- Abstract
Background: Intolerance of uncertainty (IU) correlates with posttraumatic stress disorder (PTSD) symptoms and coping-oriented alcohol use, a known risk factor for, and consequence of, alcohol use disorder (AUD). However, no studies have explicitly evaluated associations among PTSD symptoms, IU, and alcohol-related outcomes in trauma-exposed populations. The current study evaluated the main and interactive effects of PTSD symptoms and IU in relation to alcohol use and problems (i.e., past-month alcohol consumption and binge frequency, negative alcohol-related consequences, coping motives), using secondary data from a laboratory investigation of trauma and alcohol cue reactivity. Exploratory analyses were also conducted with regards to primary subfacets of IU (i.e., inhibitory IU and prospective IU). Methods: Participants were 81 college students (67% male) endorsing interpersonal trauma exposure (e.g., sexual/physical assault) and current alcohol use. Hierarchical linear regression models were conducted to evaluate aims, covarying for gender. Results: The IU main effect was significantly positively associated with alcohol coping motives (β =.42, p <.001) but no other alcohol use variables. IU did not interact with PTSD symptoms with respect to any alcohol use variables (p's >.05). Exploratory prospective IU models revealed a significant main effect of PTSD symptoms in relation to alcohol-related consequences (β =.34, p =.009) and coping motives (β =.31, p =.001). Inhibitory IU models revealed a significant main effect of PTSD symptoms in relation to alcohol coping motives (β =.30, p =.006). Both prospective IU (β =.34, p =.001) and inhibitory IU (β =.40, p <.001) were significantly positively associated with alcohol coping motives. Conclusions: Greater levels of IU relates to coping-oriented alcohol use in trauma-exposed young adult drinkers; however, IU may not inform levels of alcohol consumption or negative consequences from alcohol use in college populations.
