Abstract

Background: This study examined the moderating effects of four types of perceived social support on the relation between type D personality and post-traumatic stress disorder (PTSD) symptoms among ICU and ER nurses.Methods: Data were collected from 223 ICU and ER nurses in university or general hospitals located in Seoul. A questionnaire survey method was used for data collection and SPSS Windows 28.0 and PROCESS Macro Program were used for data analysis.Results: The results showed that only the moderating effect of senior support was statistically significant, while perceived support from family, friends, and coworkers were not. Specifically, the effect of type D personality on post-traumatic stress disorder (PTSD) symptoms was weaker in ICU and ER nurses who perceived higher social support from senior nurses.Conclusions: The study highlighted the significance of senior support in protecting the psychological health of ICU and ER nurses. Additionally, it addressed the major considerations in developing practical interventions in hospital settings.
