Army Study To Assess Risk and Resilience in Servicemembers (STARRS) is the largest study of mental health risk and resilience ever conducted among military personnel. Army STARRS investigators looked for factors that help protect a Soldier's mental health and factors that put a Soldier's mental health at risk. Army STARRS ran from July 2009 through June 2015. During that time, research findings were reported to senior Army leadership as the findings became available so the Army had the ability to apply them to ongoing health promotion, risk reduction, and suicide prevention efforts. The goal of extended to contact and reinterview the Army STARRS participants from the All Army Study (AAS), New Soldier Study (NSS), and Pre-Post Deployment Study (PPDS) components of the initial Army STARRS project. In addition to collecting primary survey data for these respondents, Michigan will continue to operate and support users of the Army STARRS Research Data Enclave, which contains the Historical Administrative Data System (HADS) as well as de-identified Army STARRS primary data and Army/DoD data for consenting soldiers.
