This systematic review examines qualitative research into the mental health issues encountered by military veteran personnel deployed to a combat zone. A small number of researchers have examined the often information-rich and complex experiences of returning personnel using a qualitative approach to data collection and analysis. However, qualitative studies have not often been appraised or synthesized. Using a qualitative method for conducting systematic review, the objectives of this article are twofold: (a) to review select research literature on veteran military populations, and (b) to describe veteran's experiences using a synthesis of themes across original qualitative research. Findings are discussed with considerations for applying qualitative research methods to future research of military service populations and implications for the provision of care.
