While most UK Service leavers experience successful transitions to civilian life, some face challenges including ill health, unemployment, debt and homelessness. In 2016, the Forces in Mind Trust (FiMT) ran a consultation on Life Transitions that identified individual resilience as an important driver of successful transition. Building on this engagement, FiMT has commissioned RAND Europe to conduct a systematic review of the literature on the effect of Service leavers’ resilience on transition pathways and outcomes.
