Factors influencing post-traumatic stress disorder among police officers in South Korea.

Objectives: This study aims to identify critical incident trauma (CIT), social support, resilience, and post-traumatic stress disorder (PTSD) in Korean police officers and to determine factors related to PTSD to obtain basic data for developing a PTSD intervention.

Methods: A mixed-methods approach was adopted by administering structured questionnaires to Korean police officers and conducting semi-structured interviews with seven Korean police stakeholders. The structured questionnaires elicited information on CIT, social support, resilience, and PTSD.
