概要	The Military Identity Scale measures the extent to which a service member's self-concept and life meaning are organized around military role and identity. While no single standardized MIS exists, military psychology researchers have developed identity measures assessing how strongly military identity is internalized, influencing both in-service adjustment and post-deployment civilian reintegration. These scales examine the degree to which individuals identify with military values, roles, and belonging, with implications for both operational resilience and civilian transition outcomes.	The DRRI-2 is a comprehensive self-report inventory measuring pre-deployment, deployment, and post-deployment risk and protective (resilience) factors influencing mental health outcomes in military personnel. Developed by King and colleagues in 2006 and refined in 2008, it captures contextual, behavioral, social, and psychological factors that shape post-deployment adjustment. It is used in military health surveillance, clinical formulation, and research examining how risk-resilience balance predicts PTSD and other adverse outcomes.
