    Distress tolerance (DT; perceived or actual ability to tolerate aversive physical or emotional states) is related to both posttraumatic stress disorder (PTSD) symptoms and substance use disorders (SUD). This investigation evaluates self-report and behavioral measures of DT as potential predictors of PTSD and SUD cognitive-behavioral therapy outcomes. Participants included 41 treatment-seeking adults (53.7% women; 73.2% African American; Mage= 44.90, SD = 9.68) who met at least four symptoms of DSM-5 PTSD and DSM-IV substance dependence, assessed via structured interviews. At baseline (pre-treatment), participants completed the Distress Tolerance Scale (DTS), Mirror-Tracing Persistence Task (MTPT), Breath Holding task, and Paced Auditory Serial Addition Task. The Clinician-Administered PTSD Scale for DSM-5 severity scores and percent days of primary substance use, measured via Timeline Follow-back, were used as indicators of PTSD symptoms and substance use, respectively. Covariates included treatment condition, baseline PTSD symptom severity, and baseline substance use. Lower perceived DT at baseline (DTS total score) was associated with higher PTSD symptom severity at end-of-treatment. Lower behavioral DT at baseline (MTPT duration) was associated with higher substance use at the conclusion of treatment (i.e., proportion of number of use days to total number of days between two final treatment sessions)

    Nonjudgmental Acceptance: Associations With Substance-Related Cue Reactivity in Adults With Substance Use Disorders and Posttraumatic Stress

    The present investigation examined the predictive utility of nonjudgmental acceptance, a facet of mindfulness defined as the ability to remain aware and nonevaluative about internal experience, in terms of substance-related cue reactivity among adults with substance use disorders (SUD) and posttraumatic stress (PTS) symptomatology. We hypothesized that higher nonjudgmental acceptance, indexed via self-report, would predict higher levels of self-reported control over oneself and safety \u27in the moment\u27, broadly, and lower levels of substance-related craving in response to substance script cues. Effects were expected after subtracting reactivity to neutral script cues from each outcome rating. PTS severity was included as a covariate. The sample was comprised of 53 adults (48.1% women; 75.9% African American; 74.1% with past-month PTSD) with substance dependence per DSM-IV and at least four symptoms of PTSD per DSM-5. Higher baseline nonjudgmental acceptance predicted greater safety and control in response to substance cues; no effects were found for craving. These experimental laboratory results elucidate the potential clinical utility of mindfulness-based interventions in bolstering recovery from addiction among adults with SUD/PTS by fostering safety and control in response to substance cues

    Linkages between Cigarette Smoking Outcome Expectancies and Negative Emotional Vulnerability

    The present investigation examined whether smoking outcome expectancies, as measured by the Smoking Consequences Questionnaire (SCQ; [Brandon, T.H., & Baker, T.B., (1991). The Smoking Consequences Questionnaire: The subjective expected utility of smoking in college students. Psychological Assessment, 3, 484–491.]), were incrementally related to emotional vulnerability factors among an adult sample of 202 daily cigarette smokers (44.6% women; Mage= 23.78 years, SD = 9.69 years). After controlling for cigarettes smoked/day, past 30-day marijuana use, current alcohol consumption, and coping style, negative reinforcement/negative affect reduction outcome expectancies were significantly associated with greater levels of negative affectivity, emotional dysregulation, and anxiety sensitivity. The observed effects for negative reinforcement/negative affect reduction also were independent of shared variance with other outcome expectancies. Negative personal consequences outcome expectancies were significantly and incrementally related to anxiety sensitivity, but not negative affectivity or emotional dysregulation. Findings are discussed in terms of the role of negative reinforcement/ negative affect reduction smoking outcome expectancies and clinically-relevant negative emotional vulnerability for better understanding cigarette smoking-negative mood problem

    Posttraumatic Stress Symptom Clusters Differentially Predict Late Positive Potential to Cocaine Imagery Cues in Trauma-Exposed Adults With Cocaine Use Disorder

    BACKGROUND: While studies have investigated the effects of posttraumatic stress disorder (PTSD) symptoms on substance use, information on these associations in the context of drug cue reactivity is lacking, which can provide meaningful information about risk for relapse. The current study assessed the associations between PTSD symptom clusters and reactivity to cues in trauma-exposed adults with cocaine use disorder. METHODS: We recorded electroencephalogram on 52 trauma-exposed participants (M RESULTS: Linear mixed modeling indicated that higher NACM symptomatology was associated with higher LPPs to cocaine cues and higher arousal/reactivity was associated with lower LPPs to cocaine cues. CONCLUSIONS: These results highlight the potential clinical utility of the LPP in assessing drug cue reactivity in trauma-exposed adults with substance use disorder
