Abstract

There is a paucity of literature on the roles of media exposure, general trust, and their interactions in long-term post-traumatic stress disorder (PTSD) symptoms after a natural disaster. Trying to address this knowledge gap, our study aimed to (a) investigate whether exposure to media coverage during the traumatic event and general trust directly affected adult survivors’ long-term PTSD symptoms 10 years after the 5.12 Wenchuan earthquake, and (b) to identify the potential differential pattern of the influence of media exposure on PTSD symptoms for adult survivors with various levels of general trust. Using cross-sectional methodology, we surveyed participants (N = 1000) recruited from six disaster-affected counties. We assessed PTSD symptoms, media exposure, general trust, demographic characteristics, socioeconomic status, and earthquake exposure. Data were analyzed descriptively and with Tobit regression analyses. Reversed relationships between general trust and PTSD were verified, whereas no direct links were found between media exposure and PTSD. Interaction tests revealed that media exposure alleviated PTSD for high-trust survivors, but aggravated PTSD for low-trust survivors. These results suggest that general trust building should be considered in post-disaster construction activities.

From 2006 to 2015, China had the highest number of people (1,019,008,563) affected by disasters in the world [1]
As one typical and common mental disorder arising after exposure to natural disasters [4], post-traumatic stress disorder (PTSD) has been a key concern for both scholars and policymakers in the recent three decades [5,6,7,8]

Summary

Introduction

From 2006 to 2015, China had the highest number of people (1,019,008,563) affected by disasters in the world [1]. This comprises 53% of disaster victims globally over the same period [1]. The. 5.12 Wenchuan earthquake was the worst disaster that occurred in these years. As one typical and common mental disorder arising after exposure to natural disasters [4], post-traumatic stress disorder (PTSD) has been a key concern for both scholars and policymakers in the recent three decades [5,6,7,8]. One meta-analysis revealed that the prevalence of PTSD after earthquakes ranged from 4.10–67.07% in adults and from
