Recent research has sought to understand how individuals high in psychopathic traits perceive pain in others (Decety, Skelly, & Kiehl, 2013; Marsh et al., 2013). Perception of pain in others is presumed to act as a prosocial signal, and underreactivity to others' pain may contribute to engagement in exploitative-aggressive behaviors among individuals high in psychopathic traits (Jackson, Meltzoff, & Decety, 2005). The current study tested for associations between facets of psychopathy as...
Show moreRecent research has sought to understand how individuals high in psychopathic traits perceive pain in others (Decety, Skelly, & Kiehl, 2013; Marsh et al., 2013). Perception of pain in others is presumed to act as a prosocial signal, and underreactivity to others' pain may contribute to engagement in exploitative-aggressive behaviors among individuals high in psychopathic traits (Jackson, Meltzoff, & Decety, 2005). The current study tested for associations between facets of psychopathy as defined by the triarchic model (Patrick, Fowles, & Krueger, 2009) and decreased sensitivity to pain in 105 undergraduates tested in a laboratory pain assessment. A pressure algometer was used to index pain tolerance, and participants also rated their perceptions of and reactivity to the algometer-induced pain during the assessment and again 3 days later. A unique positive relationship was found between pain tolerance and the meanness facet of psychopathy, which also predicted reduced fear of painful algometer stimulation. Other psychopathy facets (boldness, disinhibition) showed negative relations with fear of pain stimulation during testing and at follow-up. Findings from this study extend the nomological network surrounding callousness (meanness) and suggest that increased pain tolerance may be a mechanism contributing to insensitivity to expressions of discomfort in others.

The current studies examined the hypothesis that maturity fears are increasing among undergraduate men and women from the United States over time. Study 1 used a time-lag method to assess generational effects of maturity fears among a large sample (n = 3,291) of undergraduate men and women assessed in 1982, 1992, 2002, and 2012. Results revealed that both men and women reported significantly higher rates of maturity fears across time. Study 2 replicated these findings, and used a more...
Show moreThe current studies examined the hypothesis that maturity fears are increasing among undergraduate men and women from the United States over time. Study 1 used a time-lag method to assess generational effects of maturity fears among a large sample (n = 3,291) of undergraduate men and women assessed in 1982, 1992, 2002, and 2012. Results revealed that both men and women reported significantly higher rates of maturity fears across time. Study 2 replicated these findings, and used a more restricted time frame to more closely examine the rate of change. Undergraduate women (n = 554) were assessed in 2001, 2003, 2009, and 2012. Maturity fears were again found to increase from 2001 to 2012. Recent cohorts of emerging adults seem more reluctant to mature than previous cohorts. Many contributing factors may be at play, including challenging economic times, social pressures to remain youthful, and/or internal fears of assuming increased responsibility.

Data are available on 314 pairs of monozygotic and same-sex dizygotic twins analyzed across five waves of assessment. Univariate analyses provide a range of estimates of genetic (h²=.00-.63) and shared environmental influences (c²=.15-.52) across math calculation, fluency and problem solving measures. Multivariate analyses indicate genetic overlap between math problem solving with general cognitive ability and reading, whereas math fluency shares significant genetic overlap with reading fluency and general cognitive ability. Further, math fluency has unique genetic influences. In general, math ability has shared environmental overlap with general cognitive ability and decoding. These results indicate that aspects of math that include problem solving have different genetic and environmental influences than math calculation. Moreover, math fluency, a timed measure of calculation, is the only measured math ability with unique genetic influences.

This article reviews empirical findings regarding multiple questions relevant to the issue of free will among addicted smokers: Is smoking voluntary behavior? Can people quit smoking?

This article reviews empirical findings regarding multiple questions relevant to the issue of free will among addicted smokers: Is smoking voluntary behavior? Can people quit smoking? Why don't people quit smoking? Why do smokers relapse when they try to quit? Do addicted smokers suffer from irresistible cravings? Are there some people who cannot quit? Are there conditions that make resistance impossible? Why would they smoke knowing it can kill them? The evidence reviewed here seems most consistent with the view that smokers retain control over their actions but cannot easily stop having frequent desires to smoke.

Show moreInattentive behavior is considered a core and pervasive feature of ADHD; however, an alternative model challenges this premise and hypothesizes a functional relationship between working memory deficits and inattentive behavior. The current study investigated whether inattentive behavior in children with ADHD is functionally related to the domain-general central executive and/or subsidiary storage/rehearsal components of working memory. Objective observations of children's attentive behavior by independent observers were conducted while children with ADHD (n = 15) and typically developing children (n = 14) completed counterbalanced tasks that differentially manipulated central executive, phonological storage/rehearsal, and visuospatial storage/rehearsal demands. Results of latent variable and effect size confidence interval analyses revealed two conditions that completely accounted for the attentive behavior deficits in children with ADHD: (a) placing demands on central executive processing, the effect of which is evident under even low cognitive loads, and (b) exceeding storage/rehearsal capacity, which has similar effects on children with ADHD and typically developing children but occurs at lower cognitive loads for children with ADHD.

Show moreADHD is associated with automobile crashes, traffic fatalities, and serious road trauma, but it is unclear whether this risk is (a) driven by ADHD symptoms specifically, and (b) unique to ADHD or transdiagnostic across psychiatric disabilities, such as depression, that also have concentration problems as core symptoms. The current study provides the first prospective, continuously-monitored evaluation of crash risk related to ADHD symptoms, including the first on-road comparison of ADHD with another high-prevalence psychiatric disability (depression). A probability-based sample of 3226 drivers from six U.S. sites, including subsamples with self-reported ADHD (n = 274) and depression (n = 251), consented to have their vehicles outfitted with sophisticated data acquisition technologies to continuously monitor real-world, day-to-day driving from 'engine-on to engine-of for 1-2 years (Mean = 440 consecutive days/driver, Mean = 9528 miles/driver). Crashes and near-crashes were objectively identified via software-based algorithms and double-coded manual validation (blinded to clinical status). Miles driven, days monitored, age, gender, education, and marital status were controlled. ADHD symptoms portended 5% increased crash risk per increase in symptom severity score (IRR = 1.05). This risk corresponded to approximately 1 biennial crash and 1 annual near-crash per driver with ADHD; crash risk doubled for drivers reporting ADHD symptom severity near the sample's maximum. Analyses based on self-reported clinical status indicated similarly elevated rates for ADHD (IRR = 1.46) and depression (IRR = 1.34) that may be related, in part, to both groups' inattention/concentration symptoms. Risk was not attenuated by ADHD usual treatment, but varied according to antidepressant medication status. Previous studies have significantly underestimated the risk for traffic crashes conveyed by ADHD and depression.

In a cross-sectional design, we examined AS facets (physical, cognitive, and social concerns) in relation to tobacco use, abstinence-related problems, and cognitions in 473 treatment-seeking smokers. After controlling for sex, race, age, educational attainment, hypertension status, and neuroticism, linear regression models indicated that AS physical and cognitive concerns were associated with tobacco dependence severity (β=.13-.14, p<.01), particularly the severity of persistent smoking regardless of context or time of day (β=.14-.17, p<.01). All three AS facets were related to more severe problems during past quit attempts (β=.23-.27, p<.001). AS cognitive and social concerns were related to negative affect reduction smoking motives (β=.14, p<.01), but only the social concerns aspect of AS was related to pleasurable relaxation smoking motives and positive and negative reinforcement-related smoking outcome expectancies (β=.14-.17, p<.01). These data suggest that AS physical and cognitive concerns are associated with negative reinforcement-related smoking variables (e.g., abstinence-related problems), whereas the social concerns aspect of AS is associated with positive and negative reinforcement-related smoking variables. Together with past findings, current findings can usefully guide AS-oriented smoking cessation treatment development and refinement.

Show moreTraumatic brain injury (TBI) is both prevalent and potentially disabling. Extant literature has demonstrated women to report greater post-concussive symptoms (PCS) compared to men, highlighting the necessity of investigations into malleable, gender-linked risk factors for PCS that hold promise for reducing this gender disparity. Anxiety Sensitivity (AS) and Distress Tolerance (DT) are gender-linked risk factors that may be related to PCS. Despite a breadth of research supporting elevated AS and reduced DT in women, no study to date has investigated whether AS and DT mediate gender differences in PCS. The current sample was composed of 59 participants selected from a larger study based on their report of a past TBI. Findings indicated that AS, but not DT, significantly mediated gender differences in PCS. The present results suggest that AS is a cognitive risk factor that can partially account for the gender disparity in the expression of PCS. AS may influence an individual's interpretation of PCS as dangerous, thereby amplifying the perception of PCS severity. This suggests that efforts to reduce the burden of TBI may benefit from targeting AS in prevention and treatment paradigms, especially among women.

Show moreEmpirical evidence has identified several risk factors for panic psychopathology, including smoking and anxiety sensitivity (AS; the fear of anxiety-related sensations). Smokers with elevated AS are therefore a particularly vulnerable population for panic. Yet, there is little knowledge about how to reduce risk of panic among high AS smokers. The present study prospectively evaluated panic outcomes within the context of a controlled randomized risk reduction program for smokers. Participants (N = 526) included current smokers who all received a state-of-the-art smoking cessation intervention with approximately half randomized to the AS reduction intervention termed Panic-smoking Program (PSP). The primary hypotheses focus on examining the effects of a PSP on panic symptoms in the context of this vulnerable population. Consistent with prediction, there was a significant effect of treatment condition on AS, such that individuals in the PSP condition, compared to those in the control condition, demonstrated greater decreases in AS throughout treatment and the follow-up period. In addition, PSP treatment resulted in lower rates of panic-related symptomatology. Moreover, mediation analyses indicated that reductions in AS resulted in lower panic symptoms. The present study provides the first empirical evidence that brief, targeted psychoeducational interventions can mitigate panic risk among smokers.

Show moreApproximate number sense (ANS), the ability to rapidly and accurately compare quantities presented non-symbolically, has been proposed as a precursor to mathematics skills. Earlier work reported low heritability of approximate number sense, which was interpreted as evidence that approximate number sense acts as a fitness trait. However, viewing ANS as a fitness trait is discordant with findings suggesting that individual differences in approximate number sense acuity correlate with mathematical performance, a trait with moderate genetic effects. Importantly, the shared etiology of approximate number sense, mathematics, and general cognitive ability has remained unexamined. Thus, the etiology of approximate number sense and its overlap with math and general cognitive ability was assessed in the current study with two independent twin samples (N = 451 pairs). Results suggested that ANS acuity had moderate but significant additive genetic influences. ANS also had overlap with generalist genetic mechanisms accounting for variance and covariance in mathematics and general cognitive ability. Furthermore, ANS may have genetic factors unique to covariance with mathematics beyond overlap with general cognitive ability. Evidence across both samples was consistent with the proposal that the etiology of approximate number sense functions similar to that of mathematics and general cognitive skills.

Show moreObjective: Social problems are a key area of functional impairment for children with ADHD, and converging evidence points to executive dysfunction as a potential mechanism underlying ADHD-related social dysfunction. The evidence is mixed, however, with regard to which neurocognitive abilities account for these relations. Method: A well-characterized group of 117 children ages 8-13 (M=10.45, SD=1.53; 43 girls; 69.5% Caucasian/Non-Hispanic) with ADHD (n=77) and without ADHD (n=40) were administered multiple, counterbalanced tests of neurocognitive functioning and assessed for social skills via multi-informant reports. Results: Bayesian linear regressions revealed strong support for working memory and cross-informant interfering behaviors (inattention, hyperactivity/impulsivity) as predictors of parent- and teacher-reported social problems. Working memory was also implicated in social skills acquisition deficits, performance deficits, and strengths based on parent and/or teacher report; inattention and/or hyperactivity showed strong correspondence with cross-informant social problems in all models. There was no evidence for, and in most models strong evidence against, effects of inhibitory control and processing speed. The ADHD group was impaired relative to the non-ADHD group on social skills (d=0.82-0.88), visuospatial working memory (d=0.89), and phonological working memory (d=0.58). In contrast, the Bayesian ANOVAs indicated that the ADHD and Non-ADHD groups were equivalent on processing speed, IQ, age, gender, and SES. There was no support for or against group differences in inhibition. Conclusions: These findings confirm that ADHD is associated with impaired social performance, and implicate working memory and core ADHD symptoms in the acquisition and performance of socially-skilled behavior.

Show moreWell-designed and well-conducted clinical studies represent gold standard approaches for generating medical evidence. However, elderly populations are systematically underrepresented in studies across major chronic medical conditions, which has hampered the generalizability (external validity) of studies to the real-world patient population. It is the norm that intervention studies often require a homogeneous cohort to test their hypotheses; therefore older adults with co-medications and comorbidities are often excluded. The purpose of this study is to assess the gap between clinical studies on comorbidities and prevalence in elderly populations derived from the National Health and Nutrition Examination Survey (NHANES) and the Multiparameter Intelligent Monitoring in Intensive Care II (MIMIC-II) dataset. A comorbidity gap between them was observed and reported in this work.

Aims: The current study pilot-tested minor administration/scoring modifications to improve digit span backward's construct and predictive validities in a well-characterized sample of children with ADHD. Methods and procedures: WISC-IV digit span was modified to administer all trials (i.e., ignore discontinue rule) and count digits rather than trials correct. Traditional and modified scores were compared to a battery of criterion working memory (construct validity) and academic achievement tests (predictive validity) for 34 children with ADHD ages 8-13 (M = 10.41; 11 girls). Outcomes and results: Traditional digit span backward scores failed to predict working memory or KTEA-2 achievement (all ns). Alternate administration/scoring of digit span backward significantly improved its associations with working memory reordering (r = .58), working memory dual-processing (r = .53), working "memory updating (r = .28), and KTEA-2 achievement (r = .49). Conclusions and implications: Consistent with prior work, these findings urge caution when interpreting digit span performance. Minor test modifications may address test validity concerns, and should be considered in future test revisions. Digit span backward becomes a valid measure of working memory at exactly the point that testing is traditionally discontinued.

Show moreRumination has a large direct effect on psychopathology but has received relatively little attention in autism spectrum disorder despite the propensity to perseverate in this population. This study provided initial evidence that adolescents with autism spectrum disorder self-report more anger-focused rumination than typically developing controls, though there was substantial within-group variability. Anger rumination was positively correlated with autism symptom severity with both groups combined. Future studies that include measures of perseveration on special interests are needed to understand whether anger rumination is a manifestation of a perseverative type of repetitive behavior or a distinct trait. Even when controlling for autism symptom severity, however, anger-focused rumination was associated with poorer functioning, including more depression symptoms and overall emotional and behavioral dysregulation. Therefore, further inquiry regarding anger rumination in autism spectrum disorder is clinically important, and the potential impact of rumination-focused interventions should be explored.

Show moreTo investigate emotion regulation difficulties in association with self-reported insomnia symptoms, nightmares, and depression symptoms in a sample of current and retired firefighters. A total of 880 current and retired United States firefighters completed a web-based survey of firefighter behavioral health. Self-report measures included the Center for Epidemiologic Studies Depression Scale, Insomnia Severity Index, PTSD Checklist, and Difficulties in Emotion Regulation Scale. A notable portion of participants reported clinically significant depression symptoms (39.6%) and insomnia symptoms (52.7%), as well as nightmare problems (19.2%), each of which demonstrated a strong association with emotion regulation difficulties (rs = 0.56-0.80). Bootstrapped mediation analyses revealed that the indirect effects of overall emotion regulation difficulties were significant both for the relationship between insomnia and depression (95% CI: 0.385-0.566) and nightmares and depression (95% CI: 1.445-2.365). Limited access to emotion regulation strategies emerged as the strongest, significant indirect effect for both relationships (insomnia 95% CI: 0.136-0.335; nightmares 95% CI: 0.887-1.931). Findings extend previous affective neuroscience research by providing evidence that insomnia and nightmares may influence depression symptoms specifically through the pathway of explicit emotion regulation difficulties. Sleep disturbances may impair the ability to access and leverage emotion regulation strategies effectively, thus conferring risk for negative affect and depression.

Cognitive theories of anxiety psychopathology cite biased attention towards threat as a central vulnerability and maintaining factor. However, many studies have found threat bias indices to have poor reliability and have failed to observe the theorized relationship between threat bias and anxiety symptoms; this may be due to the non-unitary nature of threat bias and the influence of state-level variables on its expression.

Show moreCognitive theories of anxiety psychopathology cite biased attention towards threat as a central vulnerability and maintaining factor. However, many studies have found threat bias indices to have poor reliability and have failed to observe the theorized relationship between threat bias and anxiety symptoms; this may be due to the non-unitary nature of threat bias and the influence of state-level variables on its expression. Accumulating data suggests that state anxious mood is important for the robust expression of threat bias and for relations to emerge between threat bias and symptoms, though this possibility has not been experimentally tested. Eye-tracking was used to assess multiple forms of threat bias (i.e., early vigilance, sustained attention, facilitated engagement, delayed disengagement) thought to be related to anxiety. A non-clinical sample (N = 165) was recruited to test the hypothesis that biased attention towards threat, but not dysphoric or positive emotional stimuli, during an anxious mood induction, but not at a pre-stress baseline, would prospectively predict greater worry symptoms on days in which more naturalistic stressors occurred. Results revealed the hypothesized moderation effect for sustained attention towards threat after the mood induction but not at baseline, though sustained attention towards dysphoric stimuli also moderated the effect of stressors on worry. Worry-relevant sustained attention towards negative emotional stimuli may be a partially mood-context dependent phenomenon.

By conventional behavioral measures, rodents respond to natural sugars, such as glucose and fructose, as though they elicit an identical perceptual taste quality.

Show moreBy conventional behavioral measures, rodents respond to natural sugars, such as glucose and fructose, as though they elicit an identical perceptual taste quality. Beyond that, the metabolic and sensory effects of these two sugars are quite different. Considering the capacity to immediately respond to the more metabolically expedient sugar, glucose, would seem advantageous for energy intake, the present experiment assessed whether experience consuming these two sugars would modify taste-guided ingestive responses to their yet unknown distinguishing orosensory properties. One group (GvF) had randomized access to three concentrations of glucose and fructose (0.316, 0.56, 1.1 m) in separate 30-min single access training sessions, whereas control groups received equivalent exposure to the three glucose or fructose concentrations only, or remained sugar naive. Comparison of the microstructural licking patterns for the two sugars revealed that GvF responded more positively to glucose (increased total intake, increased burst size, decreased number of pauses), relative to fructose, across training. As training progressed, GvF rats began to respond more positively to glucose in the first minute of the session when intake is principally taste-driven. During post-training brief-access taste tests, GvF rats licked more for glucose than for fructose, whereas the other training groups did not respond differentially to the two sugars. Additional brief access testing showed that this did not generalize to Na-saccharin or galactose. Thus, in addition to eliciting a common taste signal, glucose and fructose produce distinct signals that are apparently rendered behaviorally relevant and hedonically distinct through experience. The taste pathway(s) underlying this remain to be identified. The T1R2+T1R3 heterodimer is thought by many to be the only taste receptor for sugars. Although most sugars have been conventionally shown to correspondingly produce a unitary taste percept (sweet), there is reason to question this model. Here, we demonstrate that rats that repeatedly consumed two metabolically distinct sugars (glucose and fructose), and thus have had the opportunity to associate the tastes of these sugars with their differential postoral consequences, initially respond identically to the orosensory properties of the two sugars but eventually respond more positively to glucose. Thus, in addition to the previously identified common taste pathway, glucose and fructose must engage distinct orosensory pathways, the underlying molecular and neural mechanisms of which now await discovery.

Show moreHere, we present a mechanistically grounded theory detailing a novel function of the behavioral immune system (BIS), the psychological system that prompts pathogen avoidance behaviors. We propose that BIS activity allows the body to downregulate basal inflammation, preventing resultant oxidative damage to DNA and promoting longevity. Study 1 investigated the relationship between a trait measure of pathogen avoidance motivation and in vitro and in vivo proinflammatory cytokine production. Study 2 examined the relationship between this same predictor and DNA damage often associated with prolonged inflammation. Results revealed that greater trait pathogen avoidance motivation predicts a) lower levels of spontaneous (but not stimulated) proinflammatory cytokine release by peripheral blood mononuclear cells (PBMCs), b) lower plasma levels of the proinflammatory cytokine interleukin-6 (IL-6), and c) lower levels of oxidative DNA damage. Thus, the BIS may promote health by protecting the body from the deleterious effects of inflammation and oxidative stress.

Show moreThe gustatory cortex (GC) is widely regarded for its integral role in the acquisition and retention of conditioned taste aversions (CTAs) in rodents, but large lesions in this area do not always result in CTA impairment. Recently, using a new lesion mapping system, we found that severe CTA expression deficits were associated with damage to a critical zone that included the posterior half of GC in addition to the insular cortex (IC) that is just dorsal and caudal to this region (visceral cortex). Lesions in anterior GC were without effect. Here, neurotoxic bilateral lesions were placed in the anterior half of this critical damage zone, at the confluence of the posterior GC and the anterior visceral cortex (termed IC2 ), the posterior half of this critical damage zone that contains just VC (termed IC3), or both of these subregions (IC2 + IC3). Then, pre- and postsurgically acquired CTAs (to 0.1 M NaCl and 0.1 M sucrose, respectively) were assessed postsurgically in 15-minute one-bottle and 96-hour two-bottle tests. Li-injected rats with histologically confirmed bilateral lesions in IC2 exhibited the most severe CTA deficits, whereas those with bilateral lesions in IC3 were relatively normal, exhibiting transient disruptions in the one-bottle sessions. Groupwise lesion maps showed that CTA-impaired rats had more extensive damage to IC2 than did unimpaired rats. Some individual differences in CTA expression among rats with similar lesion profiles were observed, suggesting idiosyncrasies in the topographic representation of information in the IC. Nevertheless, this study implicates IC2 as the critical zone of the IC for normal CTA expression.

Show moreThe present review is an overview of previous experimental work on biopsychological aspects of gambling disorder. It includes the topics 1) gambling disorder from the neuroimaging and electroencephalography (EEG) perspective, 2) cognitive, executive functioning, and neuropsychological aspects of gambling disorder, and 3) rodent models of gambling disorder. Penalties and losses in gambling can differ in terms of brain activity. Also, specific patterns of brain activity, brain anatomical traits, EEG responses, and cognitive and executive performance can discriminate pathological gamblers from nonpathological gamblers. Also, pathological gamblers can display dysfunction in such brain areas as the insula, frontal lobe, and orbitofrontal cortex. Pathological gambling is a heterogeneous disorder that can vary depending on the severity of cognition, the style of gambling (strategic or not), the prospect of recovery, proneness to relapse, and proneness to treatment withdrawal. Finally, based on rodent models of gambling, the appropriateness of gambling decision is influenced by the presence of cues, the activity of dopamine receptors, and the activity of some brain areas (infralimbic, prelimbic, or rostral agranular insular cortex). Pathological gamblers differed in terms of frontoparietal brain activation compared to nonpathological gamblers (if winning or losing a game). Pathological gamblers had dysfunctional EEG activity. The severity of gambling was linked to the magnification and content of cognitive distortions. The insula was fundamental in the distortion of cognitions linked to result analysis during gambling activity.

Methods: 540 individuals (55.6% female, mean age 36) recruited via MTurk completed online measures of exercise dependence, interoception, and history of suicidal ideation and attempts. Results: Exercise dependence symptoms and low body trust were associated with suicidal ideation. Body trust moderated the relationship between exercise dependence symptoms and suicidal ideation. Continuance in exercise despite adverse consequences and low body trust were associated with past suicide attempts. Conclusions: Body trust was associated with suicidal ideation and suicide attempts in individuals with exercise dependence symptoms, and the associations strengthened as body trust decreased. The experience of not trusting one's own body may exacerbate suicide risk in at-risk individuals. (C) 2018 Elsevier Inc. All rights reserved.

As predicted by escape theory, materialistic individuals may feel dissatisfied with their standard of living, cope with failed expectations and life stressors less effectively than others, suffer from aversive self-awareness, and experience negative emotions as a result. To cope with negative, self-directed emotions, materialistic people may enter a narrow, cognitively deconstructed mindset in order to temporarily blunt the capacity for self-reflection. Cognitive narrowing decreases inhibitions thereby engendering impulsivity, passivity, irrational thought, and disinhibited behaviors, including maladaptive consumption.

Show moreA strong predisposition to engage in sexual intercourse likely evolved in humans because sex is crucial to reproduction. Given that meeting interpersonal preferences tends to promote positive relationship evaluations, sex within a relationship should be positively associated with relationship satisfaction. Nevertheless, prior research has been inconclusive in demonstrating such a link, with longitudinal and experimental studies showing no association between sexual frequency and relationship satisfaction. Crucially, though, all prior research has utilized explicit reports of satisfaction, which reflect deliberative processes that may override the more automatic implications of phylogenetically older evolved preferences. Accordingly, capturing the implications of sexual frequency for relationship evaluations may require implicit measurements that bypass deliberative reasoning. Consistent with this idea, one cross-sectional and one 3-year study of newlywed couples revealed a positive association between sexual frequency and automatic partner evaluations but not explicit satisfaction. These findings highlight the importance of automatic measurements to understanding interpersonal relationships.

Show moreThe lateral prefrontal cortex (LPFC) is essential for higher-level cognition, but the nature of its interactions in supporting cognitive control remains elusive. Previously (Nee and D'Esposito, 2016), dynamic causal modeling (DCM) indicated that mid LPFC integrates abstract, rostral and concrete, caudal influences to inform context-appropriate action. Here, we use continuous theta-burst transcranial magnetic stimulation (cTBS) to test this model causally. cTBS was applied to three LPFC sites and a control site in counterbalanced sessions. Behavioral modulations resulting from cTBS were largely predicted by information flow within the previously estimated DCM. However, cTBS to caudal LPFC unexpectedly impaired processes that are presumed to involve rostral LPFC. Adding a pathway from caudal to mid-rostral LPFC significantly improved the model fit and accounted for the observed behavioral findings. These data provide causal evidence for LPFC dynamics supporting cognitive control and demonstrate the utility of combining DCM with causal manipulations to test and refine models of cognition.

This study characterizes the emotional experiences of individuals with BPD symptoms in a combined university and community sample. Participants (N = 150) completed a clinical interview assessing BPD symptoms and self-report measures of positive and negative emotion. A subset (n = 106) completed a measure of emotion daily for 2 weeks. Pearson's correlations and multilevel modeling were used to examine the cross-sectional and longitudinal relationships between BPD symptoms and emotions. BPD symptoms were robustly related to increased negative emotion; this relationship remained after accounting for positive emotion. BPD symptoms were weakly related to decreased positive emotion; this relationship was no longer significant after accounting for negative emotion. BPD symptoms predicted higher levels of negative and not positive emotion over 14 days. These patterns held for subscales assessing intensity, frequency, and duration of negative and positive emotions. Findings suggest that individuals with BPD features are chiefly distinguished by elevated negative emotional experience.

Show moreSocial psychology's current crisis has prompted calls for larger samples and more replications. Building on Sakaluk's (in this issue) distinction between exploration and confirmation, I argue that this shift will increase correctness of findings, but at the expense of exploration and discovery. The likely effects on the field include aversion to risk, increased difficulty in building careers and hence more capricious hiring and promotion policies, loss of interdisciplinary influence, and rising interest in small, weak findings. Winners (who stand to gain from the mooted changes) include researchers with the patience and requisite resources to assemble large samples; incompetent experimenters; destructive iconoclasts; competing subfields of psychology; and lower-ranked journals, insofar as they publish creative work with small samples. The losers are young researchers; writers of literature reviews and textbooks; flamboyant, creative researchers with lesser levels of patience; and researchers at small colleges. My position is that the field has actually done quite well in recent decades, and improvement should be undertaken as further refinement of a successful approach, in contrast to the Cassandrian view that the field's body of knowledge is hopelessly flawed and radical, revolutionary change is needed. I recommend we retain the exploratory research approach alongside the new, large-sample confirmatory work. (C) 2016 Elsevier Inc All rights reserved.

Methods: 21,132 participants were drawn from 2 nationally representative cohort studies; the 1970 British Cohort Study (BCS) and the 1958 National Child Development Study (NCDS). Child self-control was teacher-rated at age 10 in the BCS and at ages 7 and 11 in the NCDS. Participants reported their smoking status and number of cigarettes smoked per day at 5 time-points in the BCS (ages 26-42) and 6 time-points in the NCDS (ages 23-55). Both studies controlled for socioeconomic background, cognitive ability, psychological distress, gender, and parental smoking; the NCDS also controlled for an extended set of background characteristics. Results: Early self-control made a substantial graded contribution to (not) smoking throughout life. In adjusted regression models, a 1-SD increase in self-control predicted a 6.9 percentage point lower probability of smoking in the BCS, and this was replicated in the NCDS (5.2 point reduced risk). Adolescent smoking explained over half of the association between self-control and adult smoking. Childhood self-control was positively related to smoking cessation and negatively related to smoking initiation, relapse to smoking, and the number of cigarettes smoked in adulthood. Conclusions: This study provides strong evidence that low childhood self-control predicts an increased risk of smoking throughout adulthood and points to adolescent smoking as a key pathway through which this may occur.

Across three studies, we generated validity evidence for scale measures of the triarchic model constructs in a large sample (=238) of socially-housed chimpanzees. Using a consensus-based rating approach, we first identified candidate items for the chimpanzee triarchic (CHMP-Tri) scales from an existing primate personality instrument and refined these into scales. In Study 2, we collected data for these scales from human informants (=301), and examined their convergent and divergent relations with scales from another triarchic inventory developed for human use. In Study 3, we undertook validation work examining associations between CHMP-Tri scales and task measures of approach-avoidance behavior (=73) and ability to delay gratification (=55). Current findings provide support for a chimpanzee model of core dispositions relevant to psychopathy and other forms of psychopathology.

Show moreChildren and adolescents with bipolar disorder are at increased risk for suicide. Sleep disturbances are common among youth with bipolar disorder and are also independently implicated in suicide risk; thus, comorbid sleep disorders may amplify suicide risk in this clinical population. This study examined the effects of comorbid sleep disorders on suicide risk among youth with bipolar disorder. We conducted secondary analyses of baseline data from the Treatment of Early Age Mania (TEAM) study, a randomized controlled trial of individuals aged 6-15 years (mean ± SD = 10.2 ± 2.7 years) with DSM-IV bipolar I disorder (N = 379). Sleep disorders (i.e., nightmare, sleep terror, and sleepwalking disorders) and suicide risk were assessed via the WASH-U-KSADS and the CDRS-R, respectively. We constructed uncontrolled logistic regression models as well as models controlling for trauma history, a generalized anxiety disorder (GAD) diagnosis, and depression symptoms. Participants with a current comorbid nightmare disorder versus those without were nearly twice as likely to screen positive for suicide risk in an uncontrolled model and models controlling for trauma history, a GAD diagnosis, and depression symptoms. Neither a current comorbid sleep terror disorder nor a sleepwalking disorder was significantly associated with suicide risk. This pattern of findings remained consistent for both current and lifetime sleep disorder diagnoses. Youth with bipolar I disorder and a comorbid nightmare disorder appear to be at heightened suicide risk. Implications for assessment and treatment are discussed.

Show moreThis trial compared attention-deficit/hyperactivity disorder (ADHD) treatment alone, intensive reading intervention alone, and their combination for children with ADHD and word reading difficulties and disabilities (RD). Children (n = 216; predominantly African American males) in Grades 2-5 with ADHD and word reading/decoding deficits were randomized to ADHD treatment (medication + parent training), reading treatment (reading instruction), or combined ADHD + reading treatment. Outcomes were parent and teacher ADHD ratings and measures of word reading/decoding. Analyses utilized a mixed models covariate-adjusted gain score approach with posttest regressed onto pretest. Inattention and hyperactivity/impulsivity outcomes were significantly better in the ADHD (parent Hedges's g = .87/.75; teacher g = .67/.50) and combined (parent g = 1.06/.95; teacher g = .36/41) treatment groups than reading treatment alone; the ADHD and Combined groups did not differ significantly (parent g = .19/.20; teacher g = .31/.09). Word reading and decoding outcomes were significantly better in the reading (word reading g = .23; decoding g = .39) and combined (word reading g = .32; decoding g = .39) treatment groups than ADHD treatment alone; reading and combined groups did not differ (word reading g = .09; decoding g = .00). Significant group differences were maintained at the 3- to 5-month follow-up on all outcomes except word reading. Children with ADHD and RD benefit from specific treatment of each disorder. ADHD treatment is associated with more improvement in ADHD symptoms than RD treatment, and reading instruction is associated with better word reading and decoding outcomes than ADHD treatment. The additive value of combining treatments was not significant within disorder, but the combination allows treating both disorders simultaneously. (PsycINFO Database Record

Show moreThe purpose of this study was to determine if modeling school and classroom effects was necessary in estimating passage reading growth across elementary grades. Longitudinal data from 8367 students in 2989 classrooms in 202 Reading First schools were used in this study and were obtained from the Progress Monitoring and Reporting Network maintained by the Florida Center for Reading Research. Oral reading fluency (ORF) was assessed four times per school year. Five growth models with varying levels of data (student, classroom, and school) were estimated in order to determine which structures were necessary to correctly partition variance and accurately estimate standard errors for growth parameters. Because the results illustrate that not modeling higher-level clustering inflated lower-level variance estimates and in some cases led to biased standard errors, the authors recommend the practice of including classroom cross-classification and school nesting when predicting longitudinal student outcomes.

Non-suicidal self-injury (NSSI) is a strong predictor of suicidal ideation and attempts. Consistent with the interpersonal theory of suicide, preliminary evidence suggests that NSSI is associated with higher levels of perceived burdensomeness (PB) and thwarted belongingness (TB).

Show moreNon-suicidal self-injury (NSSI) is a strong predictor of suicidal ideation and attempts. Consistent with the interpersonal theory of suicide, preliminary evidence suggests that NSSI is associated with higher levels of perceived burdensomeness (PB) and thwarted belongingness (TB). However, no study to date has examined the cross-sectional and prospective relationships between NSSI, TB, PB, and suicidal ideation (SI). To fill this gap, this study examined the mediating role of TB and PB in the relationship between NSSI and SI at baseline and follow-up. Young adults (N=49) with and without histories of NSSI completed self-report measures of TB, PB, and SI at three time points over two months. NSSI history was associated with higher levels of PB, TB, and SI at all time points. TB and PB significantly accounted for the relationship between NSSI history and SI at baseline. However, the relationship between NSSI history and SI at follow-up was mediated by PB, not TB. Findings provide evidence for the roles of TB and PB in the relationship between NSSI and SI, and partial support for the interpersonal theory of suicide. Future research and clinical implications are discussed.

Combining psychophysical testing and neurometric analysis of event-related potentials (ERPs) in a fear detection task with parametrically varied fear intensities (N=45), we sought to elucidate key processes in fear perception. Building on psychophysics marking fear perception thresholds, our neurometric model fitting identified several putative operations and stages: four key processes arose in sequence following face presentation - fear-neutral categorization (P1 at 100 ms), fear detection (P300 at 320 ms), valuation (early subcomponent of the late positive potential/LPP at 400-500 ms) and conscious awareness (late subcomponent LPP at 500-600 ms). Furthermore, within-subject brain-behavior association suggests that initial emotion categorization was mandatory and detached from behavior whereas valuation and conscious awareness directly impacted behavioral outcome (explaining 17% and 31% of the total variance, respectively). The current study thus reveals the chronometry of fear perception, ascribing psychological meaning to distinct underlying processes. The combination of early categorization and late valuation of fear reconciles conflicting (categorical versus dimensional) emotion accounts, lending support to a hybrid model. Importantly, future research could specifically interrogate these psychological processes in various behaviors and psychopathologies (e.g., anxiety and depression). (C) 2016 Elsevier Ltd.

Show moreReward deprivation has been implicated in major depressive disorder and severe substance abuse, but its potential relation to alcohol use disorder (AUD) symptoms in non-treatment-seeking young adult drinkers is less clear. Depression is often comorbid with alcohol misuse, so relations of AUD with reward deprivation might be due in part to the presence of depressive symptoms in young adults. Behavioral economic theory views addiction as a state that is related in part to deficits in drug-free rewards, and therefore requires an investigation into whether reward deprivation has a direct relation to alcohol misuse that is, at least partially, independent of mood. This study evaluates the contribution of 2 facets of reward deprivation (reward availability and experience) to alcohol use, AUD symptoms, and depression in a sample of young adult heavy episodic drinkers. Data were collected from 392 undergraduates (60.4% female, 85.1% Caucasian) who reported recent heavy drinking (83.7% with at least 1 AUD symptom). Low reward availability (environmental suppression) was significantly associated with both DSM-5 AUD symptoms and alcohol-related problems after controlling for age, gender, depressive symptomatology, and drinking level. This study provides support for behavioral economic models that emphasize reward deprivation as a unique risk factor for AUD that is independent of mood and drinking level. Limited access to natural rewards may be a risk and/or maintaining factor for AUD symptoms in college student drinkers.

Determining the effect strength and clinical utility of demographics as predictors is crucial for suicide risk assessment and theory development. As such, we conducted a meta-analysis to determine the effect strength and clinical utility of demographics as predictors. Methods We searched PsycInfo, PubMed, and GoogleScholar for studies published before January 1st, 2015. Inclusion criteria required that studies use at least one demographic factor to longitudinally predict suicide ideation, attempt, or death. The initial search yielded 2,541 studies, 159 of which were eligible. A total of 752 unique statistical tests were included in analysis. Results Suicide death was the most commonly studied outcome, followed by attempt and ideation. The average follow-up length was 9.4 years. The overall effects of demographic factors studied in the field as risk factors were significant but weak, and that of demographic factors studied as protective factors were non-significant. Adjusting for publication bias further reduced effect estimates. No specific demographic factors appeared to be strong predictors. The effects were consistent across multiple moderators. Conclusions At least within the narrow methodological constraints of the existing literature, demographic factors were statistically significant risk factors, but not protective factors. Even as risk factors, demographics offer very little improvement in predictive accuracy. Future studies that go beyond the limitations of the existing literature are needed to further understand the effects of demographics.

Show moreThe dual process model of moral decision-making suggests that decisions to reject causing harm on moral dilemmas (where causing harm saves lives) reflect concern for others. Recently, some theorists have suggested such decisions actually reflect self-focused concern about causing harm, rather than witnessing others suffering. We examined brain activity while participants witnessed needles pierce another person's hand, versus similar non-painful stimuli. More than a month later, participants completed moral dilemmas where causing harm either did or did not maximize outcomes. We employed process dissociation to independently assess harm-rejection (deontological) and outcome-maximization (utilitarian) response tendencies. Activity in the posterior inferior frontal cortex (pIFC) while participants witnessed others in pain predicted deontological, but not utilitarian, response tendencies. Previous brain stimulation studies have shown that the pIFC seems crucial for sensorimotor representations of observed harm. Hence, these findings suggest that deontological response tendencies reflect genuine other-oriented concern grounded in sensorimotor representations of harm.

Research regarding the relationship between deployment, suicidality, and mental health connections has been equivocal, with some studies finding a link between deployment history and mental health outcomes, and others not. The purpose of this study was to examine the effects of military deployment on mental health and service utilization outcomes using a longitudinal design. Deployment history, mental health visits, symptoms of suicidality, and various mental health outcomes were assessed in a sample of 1,566 Army recruiters at study entry and 18-months follow-up. Deployment history was positively associated with mental health visits, number of major depressive episodes, and acquired capability for suicide at baseline; however, no significant relationship between deployment, mental health visits, and any other suicide or mental health-related outcomes emerged at baseline or follow-up. Findings suggest a disconnection from mental health services among military personnel. Implications for treatment and suicide prevention efforts among military personnel are discussed.

Show moreOBJECTIVES: The current study tested opposing predictions stemming from the failure and acting out theories of depression-delinquency covariation. METHOD: Participants included a nationwide longitudinal sample of adolescents (N = 3,604) ages 12 to 17. Competing models were tested with cohort-sequential latent growth curve modeling to determine whether depressive symptoms at age 12 (baseline) predicted concurrent and age-related changes in delinquent behavior, whether the opposite pattern was apparent (delinquency predicting depression), and whether initial levels of depression predict changes in delinquency significantly better than vice versa. RESULTS: Early depressive symptoms predicted age-related changes in delinquent behavior significantly better than early delinquency predicted changes in depressive symptoms. In addition, the impact of gender on age-related changes in delinquent symptoms was mediated by gender differences in depressive symptom changes, indicating that depressive symptoms are a particularly salient risk factor for delinquent behavior in girls. CONCLUSION: Early depressive symptoms represent a significant risk factor for later delinquent behavior--especially for girls--and appear to be a better predictor of later delinquency than early delinquency is of later depression. These findings provide support for the acting out theory and contradict failure theory predictions.

In the present study, we report on the development and validation of a revised version of the Math Anxiety Scale for Young Children (MASYC; Harari et al., 2013). We conducted cognitive interviews with the 12 MASYC items with nine children and then administered the MASYC and five newly-developed items to 296 first-, second- and third-grade children. Results from cognitive interviews show that three of the items from the original scale were being systematically misinterpreted by young children. We present a revised measure (the MASYC-R) consisting of 13 items (eight original, five newly-developed) that shows strong evidence for reliability and validity. Results also showed that a small, but meaningful, proportion of children at this age show signs of high math anxiety. Validity of the MASYC-R was supported through correlations with a number of other factors, including general anxiety, math performance, and math attitudes. In addition, results suggest that a substantial proportion of the variance in math anxiety can be explained from these other variables together. The findings suggest that the MASYC-R is appropriate for use with young children and can help researchers to answer important questions about the nature and development of math anxiety at this age.

Show moreRecent data show shifts in genetic and environmental influences on emotional eating across the menstrual cycle, with significant shared environmental influences during pre-ovulation, and primarily genetic effects during post-ovulation. Factors driving differential effects are unknown, although increased estradiol during pre-ovulation and increased progesterone during post-ovulation are thought to play a role. We indirectly investigated this possibility by examining whether overall levels of estradiol and progesterone differentially impact genetic and environmental risk for emotional eating in adult female twins (N = 571) drawn from the MSU Twin Registry. Emotional eating, estradiol levels, and progesterone levels were assessed daily and then averaged to create aggregate measures for analysis. As predicted, shared environmental influences were significantly greater in twins with high estradiol levels, whereas additive genetic effects increased substantially across low versus high progesterone groups. Results highlight significant and differential effects of ovarian hormones on etiologic risk for emotional eating in adulthood.

There are serotonergic projections to both the main (MOB) and the accessory olfactory bulb (AOB). Current-clamp experiments demonstrate that serotonergic afferents are largely excitatory for mitral cells (MCs) in the MOB where 5-HT receptors mediate a direct excitatory action. Serotonergic afferents are predominately inhibitory for MCs in the AOB.

Show moreThere are serotonergic projections to both the main (MOB) and the accessory olfactory bulb (AOB). Current-clamp experiments demonstrate that serotonergic afferents are largely excitatory for mitral cells (MCs) in the MOB where 5-HT receptors mediate a direct excitatory action. Serotonergic afferents are predominately inhibitory for MCs in the AOB. There are two types of inhibition: indirect inhibition mediated through the 5-HT receptors on GABAergic interneurons and direct inhibition via the 5-HT receptors on MCs. Differential 5-HT neuromodulation of MCs across the MOB and AOB could contribute to select behaviours such as olfactory learning or aggression. Mitral cells (MCs) contained in the main (MOB) and accessory (AOB) olfactory bulb have distinct intrinsic membrane properties but the extent of neuromodulation across the two systems has not been widely explored. Herein, we investigated a widely distributed CNS modulator, serotonin (5-HT), for its ability to modulate the biophysical properties of MCs across the MOB and AOB, using an in vitro, brain slice approach in postnatal 15-30 day mice. In the MOB, 5-HT elicited three types of responses in 93% of 180 cells tested. Cells were either directly excited (70%), inhibited (10%) or showed a mixed response (13%)- first inhibition followed by excitation. In the AOB, 82% of 148 cells were inhibited with 18% of cells showing no response. Albeit located in parallel partitions of the olfactory system, 5-HT largely elicited MC excitation in the MOB while it evoked two different kinetic rates of MC inhibition in the AOB. Using a combination of pharmacological agents, we found that the MC excitatory responses in the MOB were mediated by 5-HT receptors through a direct activation. In comparison, 5-HT-evoked inhibitory responses in the AOB arose due to a polysynaptic, slow-onset inhibition attributed to 5-HT receptor activation exciting GABAergic interneurons. The second type of inhibition had a rapid onset as a result of direct inhibition mediated by the 5-HT class of receptors. The distinct serotonergic modulation of MCs between the MOB and AOB could provide a molecular basis for differential chemosensory behaviours driven by the brainstem raphe nuclei into these parallel systems.

There is little knowledge about how emotion regulation difficulties interplay with psychopathology in terms of smoking cessation. Participants ( = 250; 53.2 % female, = 39.5, = 13.85) were community-recruited daily smokers (≥8 cigarettes per day) who self-reported motivation to quit smoking; 38.8 % of the sample met criteria for a current (past 12-month) psychological disorder.

Show moreThere is little knowledge about how emotion regulation difficulties interplay with psychopathology in terms of smoking cessation. Participants ( = 250; 53.2 % female, = 39.5, = 13.85) were community-recruited daily smokers (≥8 cigarettes per day) who self-reported motivation to quit smoking; 38.8 % of the sample met criteria for a current (past 12-month) psychological disorder. Emotion regulation deficits were assessed pre-quit using the Difficulties with Emotion Regulation Scale (DERS; Gratz and Roemer in J Psychopathol Behav Assess 26(1):41-54, 2004) and smoking behavior in the 28 days post-quit was assessed using the Timeline Follow-Back (TLFB; Sobell and Sobell in Measuring alcohol consumption: psychosocial and biochemical methods. Humana Press, Totowa, 1992). A Cox proportional-hazard regression analysis was used to model the effects of past-year psychopathology, DERS (total score), and their interaction, in terms of time to lapse post-quit day. After adjusting for the effects of gender, age, pre-quit level of nicotine dependence, and treatment condition, the model revealed a non-significant effect of past-year psychopathology ( = 1.14, = 0.82-1.61) and difficulties with emotion regulation ( = 1.01, = 1.00-1.01) on likelihood of lapse rate. However, the interactive effect of psychopathology status and difficulties with emotion regulation was significant ( = 0.98, = 0.97-0.99). Specifically, there was a significant conditional effect of psychopathology status on lapse rate likelihood at low, but not high, levels of emotion regulation difficulties. Plots of the cumulative survival functions indicated that for smokers without a past-year psychological disorder, those with lower DERS scores relative to elevated DERS scores had significantly lower likelihood of early smoking lapse, whereas for smokers with past-year psychopathology, DERS scores did not differentially impact lapse rate likelihood. Smokers with emotion regulation difficulties may have challenges quitting, and not having such difficulties, especially without psychopathology, decreases the potential likelihood of early lapse.

Neuroimaging studies of the medial prefrontal cortex (mPFC) suggest that the dorsal anterior cingulate cortex (dACC) region is responsive to a wide variety of stimuli and psychological states, such as pain, cognitive control, and prediction error (PE). In contrast, a recent meta-analysis argues that the dACC is selective for pain, whereas the supplementary motor area (SMA) and pre-SMA are specifically associated with higher-level cognitive processes (Lieberman and Eisenberger, 2015).

Show moreNeuroimaging studies of the medial prefrontal cortex (mPFC) suggest that the dorsal anterior cingulate cortex (dACC) region is responsive to a wide variety of stimuli and psychological states, such as pain, cognitive control, and prediction error (PE). In contrast, a recent meta-analysis argues that the dACC is selective for pain, whereas the supplementary motor area (SMA) and pre-SMA are specifically associated with higher-level cognitive processes (Lieberman and Eisenberger, 2015). To empirically test this claim, we manipulated effects of pain, conflict, and PE in a single experiment using human subjects. We observed a robust dorsal-ventral dissociation within the mPFC with cognitive effects of PE and conflict overlapping dorsally and pain localized more ventrally. Classification of subjects based on the presence or absence of a paracingulate sulcus showed that PE effects extended across the dorsal area of the dACC and into the pre-SMA. These results begin to resolve recent controversies by showing the following: (1) the mPFC includes dissociable regions for pain and cognitive processing; and (2) meta-analyses are correct in localizing cognitive effects to the dACC, although these effects extend to the pre-SMA as well. These results both provide evidence distinguishing between different theories of mPFC function and highlight the importance of taking individual anatomical variability into account when conducting empirical studies of the mPFC. Decades of neuroimaging research have shown the mPFC to represent a wide variety of stimulus processing and cognitive states. However, recently it has been argued whether distinct regions of the mPFC separately process pain and cognitive phenomena. To address this controversy, this study directly compared pain and cognitive processes within subjects. We found a double dissociation within the mPFC with pain localized ventral to the cingulate sulcus and cognitive effects localized more dorsally within the dACC and spreading into the pre-supplementary motor area. This provides empirical evidence to help resolve the current debate about the functional architecture of the mPFC.

Show moreDistress intolerance (DI) is conceptualized as an individual difference reflective of the ability to tolerate aversive psychological states. Although high DI has demonstrated cross-sectional associations with multiple forms of psychopathology, few studies have tested key facets of its theoretical conceptualization. Specifically, little research has been conducted on DI's theorized role as an incrementally valid prospective moderator of the relationship between daily stressful events and affective symptoms reflective of preoccupation with aversive internal (e.g., depression, worry) rather than external stimuli (e.g., social anxiety). A non-clinical sample (N = 147; 77% female; M age = 19.32) in which high DI individuals were oversampled was recruited. Participants completed baseline measures of DI and trait negative affect followed by six diary entries over a two-week period in which participants reported on daily stressors, negative affect, worry, depressive, and social anxiety symptoms. Hierarchical linear models revealed that DI positively predicted depressive and worry, but not social anxiety symptoms, independent of daily stressors and negative affect. Further, a significant interaction effect was found such that the positive association between daily stressor(s) occurrence and daily worry was significant at high, but not low DI, and a similar trend-level interaction effect was observed for depressive symptoms. The interaction for social anxiety symptoms was non-significant LIMITATIONS: Utilization of a non-clinical sample precludes generalization of results to clinical samples. Only self-reported DI was assessed, limiting conclusions to perceived as opposed to behaviorally-indexed DI. Results largely supported DI's theoretical conceptualization as an incrementally valid moderator of stress responding with relevance to particular affective symptoms.

Show moreDistress intolerance is a key vulnerability factor implicated in the maintenance and relapse of cigarette smoking. Yet, past work has not examined changes in these processes during smoking cessation treatment or their relation to smoking cessation outcomes. The aim of the present study was to examine the effect of two smoking cessation interventions on changes in self-report and behavioral distress intolerance indices during treatment, and whether these changes are associated with smoking cessation outcomes. Treatment-seeking smokers (N = 384) were randomly assigned to one of two 4-session smoking cessation treatment programs: Standard Cessation Program (SCP) or Smoking Treatment and Anxiety Management Program (STAMP). Quit dates were scheduled to coincide with the final treatment session. Physical domains of distress intolerance were assessed at baseline and at each weekly session, via the Discomfort Intolerance Scale (DIS; higher scores indicate more intolerance for discomfort) and Breath Holding Duration Task (shorter durations indicate more intolerance for respiratory distress). The STAMP condition produced a greater rate of reduction in DIS scores than did the SCP condition. Changes in DIS scores during treatment mediated the effect of STAMP treatment on 7-day point prevalence abstinence at Month 3 post-quit attempt. There were no treatment conditions differences in changes in Breath-Holding duration. Data suggest self-reported distress intolerance is malleable in the context of stress sensitivity reduction treatment, but not standard smoking cessation treatment, and such reductions may result in promotion of smoking abstinence.

This study comes from a series of nested studies examining ingestive behaviors in bulimic syndromes and specifically evaluated the satiety peptide YY (PYY) and the hunger peptide ghrelin in women with PD (n=25), bulimia nervosa-purging (BNp) (n=26), and controls (n=26). Based on distinct subjective responses to a fixed meal in PD (Keel, Wolfe, Liddle, DeYoung, & Jimerson, ), we tested whether postprandial PYY response was significantly greater and ghrelin levels significantly lower in women with PD compared to controls and women with BNp. MethodParticipants completed structured clinical interviews, self-report questionnaires, and laboratory assessments of gut peptide and subjective responses to a fixed meal. ResultsWomen with PD demonstrated a significantly greater postprandial PYY response compared to women with BNp and controls, who did not differ significantly. PD women also endorsed significantly greater gastrointestinal distress, and PYY predicted gastrointestinal intestinal distress. Ghrelin levels were significantly greater in PD and BNp compared to controls, but did not differ significantly between eating disorders. Women with BNp endorsed significantly greater postprandial hunger, and ghrelin predicted hunger. DiscussionPD is associated with a unique disturbance in PYY response. Findings contribute to growing evidence of physiological distinctions between PD and BNp. Future research should examine whether these distinctions account for differences in clinical presentation as this could inform the development of specific interventions for patients with PD.
