Trauma, substance use, and mental health symptoms in transitional age youth experiencing homelessness.

Objective: This descriptive study examined the prevalence and correlates of trauma, substance use, and mental health symptoms in homeless transitional age youth (TAY) in San Francisco.

Design & Sample: One hundred homeless TAY were recruited from a community-based organization to complete a survey on trauma, mental health symptoms, and substance use.

Measurements: We used these measures: National Institute on Drug Abuse (NIDA)-Modified Alcohol, Smoking, and Substance Involvement Screening Test (ASSIST) for frequency and risk level of substance use; the 10-item Adverse Childhood Experiences (ACEs) for prevalence of trauma; the Post-traumatic Stress Disorder Checklist for DSM-5 for post-traumatic stress disorder (PTSD) symptoms; Center for Epidemiologic Studies Depression Scale for depression symptoms; and Generalized Anxiety Disorder 7-item for anxiety symptoms.
