RESUMEN
Aggression is a costly public health problem with severe and multi-faceted negative consequences and thus, identifying factors that contribute to aggression, particularly in understudied populations, is necessary to develop more effective interventions to reduce the public health cost of aggression. The goal this study was to test whether difficulties regulating emotions moderated the association between posttraumatic stress disorder (PTSD) symptoms and aggression in a community sample of predominantly Black females with high levels of trauma exposure. Furthermore, we explored unique relations between PTSD symptom clusters and distinct subscales of difficulties regulating emotions and aggression. The sample included 601 community participants recruited from an urban public hospital. Symptoms were assessed using self-report measures including the Difficulties in Emotion Regulation Scale (DERS) and Behavioral Questionnaire-Short. Regression analyses were conducted using PTSD symptoms and total DERS to test their interaction as predictors for aggression (using BQ-Short). We found that higher levels of PTSD arousal symptoms and difficulty controlling impulses when upset were positively related to aggression. We also conducted an exploratory analysis to examine the association between PTSD symptom clusters using the Alternative Symptom Clusters hybrid model. The results suggest that some PTSD symptoms (externalizing behavior) and some emotion dysregulation processes (difficulties controlling impulses when upset), relate to aggression in independent, rather than multiplicative ways. These results offer insights for new directions of research that focuses on the independent association between specific emotion dysregulation processes and PTSD symptoms on aggression.

BACKGROUND: Theories suggest that experiences of negative and positive affect are important precursors to alcohol and illicit substance use. Research utilizing ecological momentary assessments (EMA) has generally supported the relation between momentary experiences of positive affect, but not negative affect, and subsequent substance use. Unfortunately, most of these studies have focused on alcohol use and not other substance use. The goal of this paper was to further explore the relation between momentary affect and use of both alcohol and illicit substances within a population of individuals with a history of substance use. Additionally, this study aimed to understand whether the relations between affect and substance use would vary depending on the timing of EMA assessments of affect prior to substance use. METHOD: Participants with a history of heavy substance use (N = 59) completed EMA's measuring affect and substance use using random prompts 4 times a day for 14 days. RESULTS: We found that positive affect was significantly related to later engagement in drinking, illicit substance use, and marijuana use. Moreover, timing of the affect was important. When affect was assessed in the last hour prior to substance use, relative to 7 hours prior, the relation between positive affect and illicit substance use was stronger. Negative affect was related to a lower likelihood of subsequent marijuana use, but more so when it was measured a few hours versus several hours before the use. CONCLUSION: This study further supported the relation between positive affect and both alcohol and illicit substance use.
