DSM-5 posttraumatic stress symptom dimensions and health-related quality of life among Chinese earthquake survivors

Abstract

It has been well-documented that posttraumatic stress symptoms cause impairments in health-related quality of life (HRQoL). Until now we have little data on how DSM-5 PTSD symptom dimensions relate to different aspects of HRQoL. Clarifying this question would be informative to improve the quality of life of PTSD patients. This study aimed to investigate the effects of dimensions of a well-supported seven-factor model of DSM-5 PTSD symptoms on physical and psychosocial HRQoL. A total of 1063 adult survivors of the 2008 Wenchuan earthquake took part in this study nine years after the disaster. PTSD symptoms were measured by the PTSD Checklist for DSM-5 (PCL-5). HRQoL was measured by the Medical Outcomes Survey Short Form-36 (SF-36). The associations between PTSD symptom dimensions and HRQoL were examined using structural equation models. Dysphoric arousal symptoms were found to significantly relate to physical HRQoL. Other symptom dimensions were not associated with HRQoL. Our findings contribute to the relationship between DSM-5 PTSD and HRQoL, and carry implications for further clinical practice and research on trauma-exposed individuals.

High risk of infection caused Posttraumatic Stress symptoms in individuals with poor sleep quality: A study on influence of Coronavirus disease (COVID-19) in China

“…PCL-5 is a self-report 5-point Likert-Type scale (1=not at all, and 5=extremely) with 20 items measuring PTSS of instruction, avoidance, numbing and hyperarousal. The Chinese version of PCL-5 showed excellent consistency and convergent validity in previous studies (Li et al, 2018;Liu et al, 2014). Internal consistency (Cronbach's α ) of PCL-5 in the present study was 0.87.…”

A Network Analysis of Post-traumatic Stress Disorder Symptoms and Correlates During the COVID-19 Pandemic

“…Empirical studies also showed that the factor structure of PTSD symptoms was varying in different traumatic experiences (18)(19)(20). Moreover, the relationships between PTSD symptoms and other psychological symptoms (e.g., anxiety, depression, and quality of life) (21)(22)(23)(24), as well as the responses to treatment are changeable for different PTSD symptoms (25). However, neither the most central PTSD symptoms related to COVID-19 nor the related covariates were clear yet.…”

A comparison of ICD-11 and DSM-5 criteria for PTSD among a representative sample of Chinese earthquake survivors

“…The data used in this study were acquired from an epidemiological sample of adult Chinese earthquake survivors (Li et al, 2018 ). Participants were recruited from five rebuilt communities in Hanwang Town which was almost completely destroyed by the 2008 Wenchuan Earthquake, Sichuan Province, China.…”
