Impulsivity and Alcohol Use Coping Motives in a Trauma-Exposed Sample: The Mediating Role of Distress Tolerance

The present investigation examined the mediating role of distress tolerance in the association between impulsivity and alcohol use coping motives among trauma-exposed individuals. Participants were 86 adults (64.3% women; M(age) = 23.4, SD = 9.3) who met the DSM-IV-TR posttraumatic stress disorder (PTSD) criterion A for at least one traumatic life event and endorsed alcohol use in the past month. Distress tolerance at least partially mediated the association between impulsivity and alcohol use coping motives, after controlling for the variance explained by PTSD symptom severity and alcohol use problems. Clinical implications and future directions related to this line of inquiry are presented and discussed.
