PTSD and Substance Abuse among Homeless War Veterans

Abstract

This research study aims to understand the correlation between PTSD and substance abuse among homeless war veterans. By utilizing a mixed method design, this study focuses on how individuals that experience PTSD will also likely experience a substance abuse disorder at some stage in their lives. This study hypothesizes that homeless war veterans who have PTSD are more at risk of having a substance abuse disorder. We will recruit 200 participants for a 15-minute survey which will include the PCL- 5 questionnaire, examining the severity of PTSD and the Drug Abuse Screening Test (DAST-10) in addition to several socio-demographic questions. Around 20-30 participants will be invited to take part in in-depth interviews to provide further insights into their personal experiences and perceptions regarding PTSD and substance abuse. The findings from this study will provide a deeper understanding of the high rates of co-occurring PTSD and substance use disorders among homeless war veterans.
