This study will address the Traumatic Brain Injury and Psychological Health Research Program’s (TBIPHRP) focus area related to examination of care systems that can facilitate continued functional recovery among U.S. Army service members. It will specifically address the quality of treatment offered by the Army Substance Use Disorder Clinical Care (SUDCC) treatment program at Fort Cavazos, TX. This study will conduct a retrospective analysis of medical records and conduct interviews with current patients and treatment providers to gain insights into what factors contribute to soldiers’ success in their alcohol use treatment in SUDCC’s voluntary and mandatory treatment tracts. The research will specifically delve into how health, work, family, sleep, motivation, treatment options, and individual differences may impact their treatment outcomes. This study will seek to fill a significant gap in knowledge regarding our understanding of the range of experiences and outcomes that active duty soldiers receive from the Army’s SUDCC program.
