Abstract

Alcohol misuse, PTSD, and sleep disturbance often co-occur among veterans of post 9/11/2001 conflicts, however, the relations among these conditions have not been fully explored. The current study aimed to investigate the additive effects of PTSD and sleep disturbance on alcohol misuse. Participants included 110 veterans and active military personnel who served in a combat deployment following September 11th, 2001 (Mage=37.02, SD=7.74; 87% Male; 62% White). Bivariate correlations revealed total PTSD severity was significantly associated with sleep disturbance and with alcohol misuse, as expected; however, no significant association between sleep disturbance and alcohol misuse was observed, contrary to prior research. Additionally, regression analysis showed that sleep disturbance did not explain unique variance in alcohol use, beyond the role of PTSD severity. These findings suggest that an additive model does not fit the data from the present sample and a complex set of relations among these variables likely exists.
