Research examining emotion dysregulation and alcohol use has increased exponentially over the past decade. However, these studies have been limited by their use of cross-sectional designs and narrow definitions of emotion dysregulation. To address these significant gaps in the extant literature, this study utilized state-of-the-art methodology (i.e., experience sampling) and statistics (i.e., dynamic structural equation modeling) to examine potential reciprocal associations between negative and positive emotion dysregulation and alcohol use at the momentary level.Participants were 145 community women (mean age = 40.56, 40.3% white) experiencing intimate partner violence (IPV) and using substances. Surveys assessing negative and positive emotion dysregulation and alcohol use (i.e., number of standard drinks) were administered three times a day for 30 days using phone-based interactive voice recording.Significant contemporaneous effects indicated that negative and positive emotion dysregulation both co-occurred with alcohol use. However, levels of negative and positive emotion dysregulation did not predict later alcohol use, nor did alcohol use predict later levels of negative or positive emotion dysregulation. There was significant variability among participants in cross-lagged effects.Findings showed that negative and positive emotion dysregulation co-occurred with alcohol use and that there was significant interindividual variability in the cross-lagged associations between negative and positive emotion dysregulation and alcohol use. Research using idiographic approaches may identify women experiencing IPV for whom negative and positive emotion dysregulation drive alcohol use and alcohol use drives negative and positive emotion dysregulation.

BACKGROUND: Rates of both depression and alcohol use are disproportionately higher among American Indian (AI) adolescents than adolescents in the general population. The co-occurrence of depression and alcohol use is highly comorbid and clinically relevant given reciprocal negative influences on outcomes. Family factors may be especially relevant for conferring some buffering effect in this relationship due to the importance of kinship and community in AI communities. The purpose of the current study is to examine the roles of family warmth and parent monitoring in the association between depressive symptoms and alcohol use in a large, nationally representative sample of AI adolescents. METHODS: Data collected from 2009–2013 included 3,498 AI 7(th)-12(th) graders residing on or near a reservation (47.8% female). Participants reported on their depressive symptoms, family factors, and alcohol use. RESULTS: Depressive symptoms were statistically significantly positively associated with alcohol use (r=.11, p
