Post-traumatic stress disorder and depression symptoms of adolescents survived from a seriously-hit area in China: A 3-year follow-up study.

ABSTRACT

The objective of this study is to analyze the prevalence of probable PTSD and depression after earthquake and to find the risk factors. Adolescents having experienced an earthquake were recruited (n = 330) and assessed within 1 month of the trauma. Follow-up surveys were conducted 12 months, 24 months and 36 months later, respectively. Symptoms were assessed by the Children's Revised Impact of Event Scale and the Depression Self-Rating Scale for Children. Results indicate that the prevalence of probable PTSD in different stages was 42.2%, 20.1%, 30.3% and 11.2%. The corresponding rate of depression was 32.3%, 20.7%, 31.0% and 30.3%. The sub-symptoms of PTSD, intrusion and arousal, tended to decrease at the 1st year, followed by a rebound at the 2nd year, then dropping again at the 3rd year. The avoidance showed a consistent diminishing. The PTSD symptoms were significantly associated with gender and the degree of earthquake exposure. However, the gender, family relationship and despair played crucial roles in the development of depressive symptoms. Despite of the tendency of timing abatement, the prevalence of probable PTSD and depression might show rebound at the second year, which remind us a vital threshold for psychological intervention.
