Posttraumatic Stress Disorder and its Predictors in Adolescents After Earthquake in China.

J in and Li (2015) described the longitudinal prevalence of posttraumatic stress disorder (PTSD) in adolescent survivors of the Yushu earthquake in China and explored the risk factors for PTSD. They reported a prevalence of PTSD of 10.9% after 6 months and 5.8% after 24 months. They identified bereavement, being buried in the ruins, and personal injury as the risk factors for PTSD. I have some concerns on their study. First, Zhang et al. (2015) explored the somatic symptoms associated with PTSD in child and adolescent survivors at 3 and 6months after the Lushan earthquake in China. The prevalence of PTSDwas 37.4% after 3 months and 24.2% after 6 months after the earthquake, and the most common somatic symptoms were sleeping difficulty, which was reported in 58.4% and 48.4% of the subjects at 3 and 6 months, respectively. In addition, sleeping difficulty, headache, and shortness of breath were predictors of PTSD symptoms occurring at 6 months after the earthquake. The absolute prevalence after 6 months was different between the two studies, and the independent variables used for the analyses were also different. I suppose that the independent variables for predicting PTSD should be considered for further study.
