Abstract
Background: One-third of women who experience intimate partner violence (IPV) are identified as having alcohol use problems. Yet, little research has examined factors that may increase the risk of alcohol use among this high-risk population. Objectives: This study overcomes limitations of previous research by using micro-longitudinal methods to examine how fluctuations in PTSD symptoms throughout the day are associated with proximal drinking behavior and whether these associations are related to individuals' overall PTSD severity and race/ethnicity. Methods: Using phone-based interactive voice response, 244 female victims of current IPV reported their PTSD symptoms and drinking four times daily for 14 days. Results: Results indicated positive associations between PTSD symptom cluster severity and drinking level at the person, daily and within-day levels. The effects of within-person fluctuations in daily levels of PTSD severity on levels of drinking were stronger for individuals with lower PTSD severity. No evidence was found for within-person differences on time-lagged effects of PTSD on drinking or by racial/ethnic group. Further, in time-lagged models no evidence was found for reverse causation whereby alcohol use predicts increased PTSD symptom severity. Conclusions: Findings suggest that IPV-exposed women use alcohol to alleviate their PTSD symptoms at the micro-process level and that prevention and treatment efforts targeting PTSD symptoms may be useful in reducing alcohol use in this population. Further, these efforts should consider the overall severity of PTSD symptoms experienced given the differential findings among women with higher vs. lower PTSD symptom severity.
