Symptoms of posttraumatic stress disorder, depression, and anxiety among adolescents following the 2008 Wenchuan earthquake in China.

This study examined the symptoms of posttraumatic stress disorder (PTSD), anxiety, and depression among 2,250 adolescents 6 months after the 2008 Wenchuan earthquake in China. Results showed that 15.8%, 40.5%, and 24.5% of participants reported clinical symptoms of PTSD, anxiety, and depression, respectively. Posttraumatic stress disorder, anxiety, and depression were highly comorbid. Risk factors for symptoms of the 3 disorders were female gender, older age, and earthquake disaster exposure. In addition, the interaction effects of residence (urban/rural) and number of siblings of study subjects on symptoms of the 3 disorders were examined. Implications of findings on intervention and prevention of mental health problems among adolescents after experiencing earthquake disasters are discussed.
