ABSTRACT
OBJECTIVE: Posttraumatic stress disorder (PTSD) has a well-established theoretical and empirical relation with impulsivity. Prior research has not used a multidimensional approach for measuring both PTSD and impulsivity constructs when assessing their relationship. METHOD: The current study assessed the unique relationship of impulsivity facets on PTSD symptom clusters among a nonclinical sample of 412 trauma-exposed adults. RESULTS: Linear regression analyses revealed that impulsivity facets best accounted for PTSD's arousal symptoms. The negative urgency facet of impulsivity was most predictive, because it was associated with all of PTSD's symptom clusters. Sensation seeking did not predict PTSD's intrusion symptoms, but did predict the other symptom clusters of PTSD. Lack of perseverance only predicted intrusion symptoms, while lack of premeditation only predicted PTSD's mood/cognition symptoms. CONCLUSIONS: Results extend theoretical and empirical research on the impulsivity-PTSD relationship, suggesting that impulsivity facets may serve as both risk and protective factors for PTSD symptoms.

More investigation is needed to understand how specific posttraumatic stress disorder (PTSD) symptom clusters relate to the internal experience of anger and overt negative behaviors in response to anger (negative expressivity). We investigated whether anger mediated relations between PTSD symptom clusters and negative expressivity. Multiple regression revealed lower PTSD intrusion symptoms associated with higher levels of negative expressivity. Anger mediated this relationship. Higher avoidance symptoms related to higher negative expressivity. Clinical implications, limitations, and strengths are discussed.

The aims of the present study were first to identify discrete patterns of childhood victimization experiences including crime, child maltreatment, peer/sibling victimization, sexual violence, and witnessing violence among adult trauma victims using latent class analysis; second, to examine the association between class-membership and suicidal behavior, and third to investigate the differential role of dispositional anger on the association between class-membership and suicidal behavior. We hypothesized that those classes with accumulating exposure to different types of childhood victimization (e.g., poly-victimization) would endorse higher suicidal behavior, than the other less severe classes, and those in the most severe class with higher anger trait would have stronger association with suicidal behavior. Respondents were 346 adults (N=346; Mage=35.0years; 55.9% female) who had experienced a lifetime traumatic event. Sixty four percent had experienced poly-victimization (four or more victimization experiences) and 38.8% met the cut-off score for suicidal behavior. Three distinct classes emerged namely, the Least victimization (Class 1), the Predominantly crime and sibling/peer victimization (Class 2), and the Poly-victimization (Class 3) classes. Regression analysis controlling for age and gender indicated that only the main effect of anger was significantly associated with suicidal behavior. The interaction term suggested that those in the Poly-victimization class were higher on suicidal behavior as a result of a stronger association between anger and suicidal behavior in contrast to the association found in Class 2. Clinical implications of findings entail imparting anger management skills to facilitate wellbeing among adult with childhood poly-victimization experiences.

BACKGROUND: Posttraumatic stress disorder (PTSD) and major depressive disorder (MDD) are highly comorbid (Elhai et al., 2008. J. Clin. Psychiatry, 69, (4), 597-602). Rumination is a cognitive mechanism found to exacerbate and maintain both PTSD and MDD (Elwood et al., 2009. Clin. Psychol. Rev. 29, (1), 87-100; Olatunji et al., 2013. Clin. Psychol.: Sci. Pract. 20, (3), 225-257). AIMS: Assess whether four rumination subtypes moderate the relationship between comorbid PTSD and MDD symptoms. METHOD: We consecutively sampled patients (N=45) presenting to a mental health clinic using self-report measures of PTSD and MDD symptoms, and rumination in a cross-sectional design. RESULTS: Repetitive rumination moderates the relationship between PTSD and MDD symptoms at one standard deviation above the mean (ß=.044, p=.016), while anticipatory rumination moderates the relationship between PTSD and MDD symptoms at mean levels and higher levels of anticipatory rumination (mean ß=.030, p=.042; higher ß=.060, p=.008). DISCUSSION: Repetitive and anticipatory rumination should be assessed in the context of comorbid PTSD and MDD and interventions should focus on reducing these rumination subtypes. LIMITATIONS: Results should be replicated with other trauma populations because the number and complexity of traumatic events may impact the assessed symptoms. Constructs should also be assessed longitudinally, in order to establish causality. We are unable to confirm why rumination styles moderated the relationship between PTSD and depression or why counterfactual thinking and problem-focused thinking did not moderate the relationship between the two constructs.

Acculturative stress is a risk factor for depression, and may be important in the risk for depression among acculturating Japanese adolescents. However, little to no research has been published on the mental health of acculturating Japanese adolescents. Further, although family cohesion has been shown to be protective against depression across ethnic groups, no prior research has examined family cohesion as a protective factor for Japanese adolescents. To examine these relationships, 26 Japanese temporary resident adolescents and 76 parents in the Midwest were recruited to participate. Moderate to strong correlations between acculturative stress, depression, likelihood for and seriousness of family conflict were found. A regression analysis found that likelihood for family conflict moderated the relationship between acculturative stress and depression. Findings broaden our understanding of the role of acculturative stress and family conflict on depression risk for Japanese adolescent immigrants.

RATIONALE: Individuals with attention deficit hyperactivity disorder (ADHD) have a more difficult time quitting smoking compared to their non-ADHD peers. Little is known about the underlying behavioral mechanisms associated with this increased risk. OBJECTIVES: This study aims to assess the effects of 24-h smoking abstinence in adult smokers with and without ADHD on the following outcomes: smoking-reinforced responding, withdrawal, and cognitive function. METHODS: Thirty-three (n = 16 with ADHD, 17 without ADHD) adult smokers (more than or equal to ten cigarettes/day) were enrolled. Each participant completed two experimental sessions: one following smoking as usual and one following biochemically verified 24-h smoking abstinence. Smoking-reinforced responding measured via a progressive ratio task, smoking withdrawal measured via questionnaire, and cognition measured via a continuous performance test (CPT) were assessed at each session. RESULTS: Smoking abstinence robustly increased responding for cigarette puffs in both groups, and ADHD smokers responded more for puffs regardless of condition. Males in both groups worked more for cigarette puffs and made more commission errors on the CPT than females, regardless of condition. Smoking abstinence also increased ratings of withdrawal symptoms in both groups and smokers with ADHD, regardless of condition, reported greater symptoms of arousal, habit withdrawal, and somatic complaints. Across groups, smoking abstinence decreased inhibitory control and increased reaction time variability on the CPT. Abstinence-induced changes in inhibitory control and negative affect significantly predicted smoking-reinforced responding across groups. CONCLUSIONS: Smokers with ADHD reported higher levels of withdrawal symptoms and worked more for cigarette puffs, regardless of condition, which could help explain higher levels of nicotine dependence and poorer cessation outcomes in this population. Abstinence-induced changes in smoking-reinforced responding are associated with changes in inhibitory control and negative affect regardless of ADHD status, a finding that may lead to novel prevention and treatment programs.
