Post-traumatic stress disorder and occupational characteristics of police officers in Republic of Korea: a cross-sectional study.

The high-risk classification was observed in 41.11% of all officers who had experienced traumatic events, and this frequency is greater than that for other specialised occupations (eg, firefighters). Therefore, we conclude that groups with an elevated proportion of high-risk respondents should be a priority for PTSD treatment, which may help increase its therapeutic effect and improve the awareness of PTSD among South Korean police officers.
