ABSTRACT
Objective: The aim of the present study was to evaluate the relationship of posttraumatic stress disorder (PTSD) with impulsivity dimensions while controlling the effect of anxiety and depression in a sample of inpatients with alcohol use disorder (AUD). Methods: Participants were 190 male patients admitted to a specialized center for substance use disorders within a six month period. Participants were evaluated with the State-Trait Anxiety Inventory (STAI), Beck Depression Inventory (BDI), the Short Form Barratt Impulsiveness Scale (BIS-11-SF), the Traumatic Experiences Checklist, and PTSD Checklist-Civilian version. Results: Age was lower in the group with PTSD (n = 63, 33.2%) than the group without PTSD (n = 127, 66.8%). Duration of education, marital, and employment status did not differ between the groups. STAI, BDI, and BIS-11-SF scores were higher in the group with PTSD. Trait anxiety, depression, and impulsivity predicted high PTSD risk in a logistic regression model. Same variables predicted the severity of PTSD symptoms in a linear regression. Among dimensions of impulsivity attentional component was the only predictor of PTSD symptoms severity, not motor or nonplanning impulsivity. Conclusions: These findings suggest that the PTSD may be related to impulsivity, particularly attentional impulsivity, even after controlling anxiety and depression among inpatients with AUD.
