BACKGROUND: Earthquake exposure has often been associated with psychological distress. However, little is known about the cumulative effect of exposure to two earthquakes on psychological distress and in particular, the effect on the development of post-traumatic stress disorder (PTSD), anxiety and depression disorders. AIMS: This study explored the effect of exposure on mental health outcomes after a first earthquake and again after a second earthquake. METHODS: A population-based mental health survey using self-report questionnaires was conducted on 278 people in the hard-hit areas of Lushan and Baoxing Counties 13-16 months after the Wenchuan earthquake (Sample 1). 191 of these respondents were evaluated again 8-9 months after the Lushan earthquake (Sample 2), which struck almost 5 years after the Wenchuan earthquake. RESULTS: In Sample 1, the prevalence rates for PTSD, anxiety and depression disorders were 44.53, 54.25 and 51.82%, respectively, and in Sample 2 the corresponding rates were 27.27, 38.63 and 36.93%. Females, the middle-aged, those of Tibetan nationality, and people who reported fear during the earthquake were at an increased risk of experiencing post-traumatic symptoms. CONCLUSIONS: Although the incidence of PTSD, anxiety and depression disorders decreased from Sample 1 to Sample 2, the cumulative effect of exposure to two earthquakes on mental health problems was serious in the hard-hit areas. Therefore, it is important that psychological counseling be provided for earthquake victims, and especially those exposed to multiple earthquakes.
