This study aims to verify whether the PTSD risk group differs according to the socio-demographic characteristics of Korea Coast Guard Officers and derive policy implications for PTSD status survey and improvement based on this. To this end, we reviewed previous studies on socio-demographic characteristics that differ in the PTSD risk group and previous studies on PTSD characteristics of (land) police officials and firefighters performing similar tasks to Korea Coast Guard Officers. Based on the results of the review, the difference between PTSD risk groups and socio-demographic characteristics of Korea Coast Guard Officers was verified through a chi-square test using survey data conducted by Dongguk University at the request of the Korea Coast Guard in 2022. As a result, it was the age group that showed statistically significant differences in the PTSD risk group among the socio-demographic characteristics. In other words, it is necessary to issue a personnel appointment in consideration of at least the age group at workplaces where many traumatic events can be experienced when placing workplaces. In addition, the data used in this study have limitations in closely identifying variables that may affect PTSD in addition to socio-demographic characteristics, so we propose the implementation of a detailed status survey.
