Gender Differences in the Associations Between Posttraumatic Stress Symptoms and Problematic Substance Use in Psychiatric Inpatient Adolescents

Abstract

This study examined gender differences in the associations between posttraumatic stress symptoms and problematic substance use in psychiatrically hospitalized adolescents. Ninety-five adolescent inpatients (38 boys, 57 girls) were systematically evaluated with a battery of psychometrically well-established self-report measures to assess trauma exposure, posttraumatic stress symptoms, problematic alcohol and drug use, and internalizing and externalizing psychopathology. Twenty-three percent (N = 22) of patients met DSM-IV-based symptom criteria for PTSD, and 37% (N = 35) and 34% (N = 32) of patients endorsed problematic levels of drug and alcohol use, respectively. Posttraumatic stress symptoms were significantly associated with problematic drug and alcohol use in girls but not in boys. There were no significant gender differences in posttraumatic stress symptoms and/or problematic substance use, to account for the gender differences in the association between PTSD and substance use. Our findings suggest that the link between substance abuse and PTSD may be especially salient for female adolescents.
