Abstract

Background: Minimal research has examined utility of PC-PTSD-5 in family members of frontline medical workers. The aims of our study were to develop and elucidate the psychometric properties of the Chinese version of the PC-PTSD-5 and to determine its usefulness in screening for possible PTSD in relatives of Chinese healthcare workers during the COVID-19.Methods: We conducted a cross-sectional research in the relatives of medical staffs working in a general hospital during the COVID-19. Descriptive analysis was used to characterize demographic information of family members to find factors associated with PTSD symptoms. For reliability test, the internal consistency of PC-PTSD-5 was accessed using Cronbach's alpha coefficient. A validity test was assessed by Pearson's correlation between scales. A receiver operating characteristic (ROC) curve was used to evaluate the optimal cutoff score with the maximum Youden Index in this study.Results: The result of demographic information indicated that gender and the type of work undertaken by medical staff in the family have a potential impact on the PTSD symptoms of medical staff's family members. Cronbach's alpha coefficient of PC-PTSD-5 was 0.83, indicating the high reliability. Good validity was also demonstrated by Pearson coefficient. By calculating the Youden index, a cutoff score of 2 was found to be optimal in our study, with sensitivity of 80.74% and specificity of 88.43%.Conclusions: Our study has demonstrated the robust psychometric strengths of the PC-PTSD-5, introducing a reliable tool for screening PTSD among vulnerable and neglected families of these medical workers.

Highlights

Post-traumatic stress disorder (PTSD) is a psychiatric disorder which is common in various public health emergencies
Due to the high risk of cluster transmission, lack of professional medical knowledge, and inadequate mental health care services it is speculated that the COVID-19 pandemic posed a particular threat to the family members of frontline medical staff which may have raised their risk for developing trauma-related symptoms
The result of this study demonstrated the psychometric robustness of Primary Care Post-traumatic Stress Disorder Screen (PC-PTSD)-5 in this sample of family members of medical staff on the frontline of the COVID-19 pandemic

Summary

Introduction

Post-traumatic stress disorder (PTSD) is a psychiatric disorder which is common in various public health emergencies. Healthcare staff work against the epidemic in environments which are fast-paced and high-pressure, with high risk of infection of COVID-19, placing them in direct danger. This can disrupt family schedules, upset children, and cause worry and distress in spouses and relatives. Due to the high risk of cluster transmission, lack of professional medical knowledge, and inadequate mental health care services it is speculated that the COVID-19 pandemic posed a particular threat to the family members of frontline medical staff which may have raised their risk for developing trauma-related symptoms. The aims of our study were to develop and elucidate the psychometric properties of the Chinese version of the PC-PTSD-5 and to determine its usefulness in screening for possible PTSD in relatives of Chinese healthcare workers during the COVID-19
