Few studies to date have examined psychological sequelae of natural disasters among the elderly in China. The aim of this study was to investigate the prevalence rates of probable post-traumatic stress disorder (PTSD), anxiety and depression in the elderly survivors a year after the Wenchuan earthquake as well as to analyse related risk factors. The community-based sample of the study consisted of 284 elderly survivors (≥60 years). PTSD was assessed by the PTSD Checklist--Civilian version, and anxiety and depression were assessed by the Hopkins Symptoms Checklist. In total, the estimated prevalence rates of probable PTSD, anxiety and depression were 26.3%, 42.9% and 35.2%, respectively. Nearly a fifth of the elderly participants reported symptoms that meet the criteria for all three of these mental disorders. Results indicated that some factors associated with earthquake-exposure intensity, which included loss of livelihood, bereavement, injury and initial fear during the earthquake, were among the significant risk factors for these mental disorders. Women had a higher risk of suffering from probable anxiety as compared to men. Finally, the significance and limitations of this study were also discussed.
