In recent years, mental health of naval officers and soldiers has attracted wide attention. The present research reviewed literatures on the mental health of naval officers and soldiers from 2009 to 2019, and summarized the characteristics, influencing factors and mental health intervention. The common psychological problems of naval officers and soldiers were depression, anxiety and sleeping problems; the comparative research of mental health level between naval personnel and other military services was still controversial; the branch of the navy, long-term and long-distance navigation as well as personal factors (personality, coping style and life events) influenced their mental health; and only few researches focused on mental health intervention of naval officers and soldiers. The present problems in mental health researches of naval personnel included small scale, inconsistent results, single research method and lack of experimental research. Future studies are needed to expand the sample size and diversity of naval branches, explore the promotion effect of psychological intervention on the mental health, and emphasize to the impact of various military stress factors on the mental health of naval officers and soldiers.
