*****************************************************************************************
The Army Study to Assess Risk and Resilience in Servicemembers (STARRS) is an extensive study of mental health risk and resilience among military personnel. Army STARRS consists of eight separate but integrated epidemiologic and neurobiologic studies. Survey data for three of the Army STARRS study components are available via Secure Dissemination or via the ICPSR Virtual Data Enclave: New Soldier Study (NSS); All Army Study (AAS) and Pre-Post Deployment Study (PPDS). Also available are data for the STARRS-Longitudinal Study (STARRS-LS), which are follow-up surveys conducted with Army STARRS participants from AAS, NSS and PPDS studies. Lastly, baseline administrative data from the Army/Department of Defense (DoD) and blood sample flags for Soldiers who had blood drawn as a part of their participation in NSS or PPDS are available.
The AAS component of Army STARRS assesses soldiers' psychological and physical health, events encountered during training, combat, and non-combat operations, and life and work experiences across all phases of Army service. The AAS data includes data on soldiers' psychological resilience, mental health, and risk for self-harm.
The NSS data are drawn from new soldiers who have just entered the Army. The data contain information on soldier health, personal characteristics, and prior experiences. Results from a series of neurocognitive tests are also included in the NSS data.
The PPDS data are drawn from active duty soldiers who were interviewed at four points in time: 3-4 months prior to deployment to Afghanistan; within 1-2 weeks after return from deployment; 1-3 months after return from deployment; and 9-12 months after return from deployment. The PPDS data contain information on soldiers' psychological resilience, mental health, deployment experiences, and risk for self-harm.
The STARRS-LS data are from multiple follow-up interviews with individuals who previously participated in the AAS, NSS and PPDS study components of Army STARRS. STARRS-LS data contain follow-up information on soldiers' and veterans' physical and mental health, resilience and risk for self-harm, military and employment status, deployment experience, and personal characteristics as they move through their Army careers and after they leave the Army.

description: Analysis of Army STARRS/STARRS-LS study data requires the use of weights to correct for differential probabilities of selection as well as nonresponse. To conduct weighted analyses, AAS (Dataset 1) contains weight variable, WGT_AAS, and NSS (Dataset 2) contains weight variable, WGT_NSS. For the PPDS studies (Datasets 5, 6, 7, and 8), a table called PPDS_WEIGHTS (Dataset 4) contains weights for various combinations of participation in each wave of PPDS data collection. Finally, STARRS-LS Wave 1 (Dataset 9) contains weight variable WEIGHT_LSW1_NORM, STARRS-LS Wave 2 (Dataset 10) contains weight variable WEIGHT_LSW2_NORM, STARRS-LS Wave 3 (Dataset 11) contains weight variables WEIGHT_LSW3_NORM and WEIGHT_LSW3_WITH_LSW2_NORM (for respondents who completed both LSW2 and LSW3 surveys), STARRS-LS Wave 4 (Dataset 13) contains weight variables WEIGHT_LSW4_NORM and WEIGHT_LSW4_WITH_LS2LS3_NORM (for respondents who completed LSW2, LSW3, and LSW4 surveys). Weights provided for each study can be applied in analysis of the AAS, NSS, PPDS, STARRS-LS Wave 1, STARRS-LS Wave 2, STARRS-LS Wave 3, and STARRS-LS Wave 4 survey data. For information on survey weights, please see the Analysts' Guide for Weighted Estimation and Design-based Inference section of the ICPSR User Guide.
