Posttraumatic stress disorder in adolescents after Typhoon Morakot-associated mudslides

The aims of this study were to examine prevalence rate of post-traumatic stress disorder (PTSD), its associated factors and co-occurring psychological problems in a group of displaced adolescents 3 months following Typhoon Morakot in Taiwan. The relationship of trauma dimension and PTSD was also explored. A total of 271 adolescents who had been evacuated from their homes participated in this school-based survey. Adolescents were interviewed using the Mini-International Neuropsychiatric Interview for Children and Adolescents. Subjects themselves completed the following questionnaires: an inventory of exposure experiences to Typhoon Morakot, the Chinese version of Impact of Events Scale-Revised, the Center for Epidemiological Studies Depression Scale, and the Family APGAR Index. Teachers completed the Teacher's Report Form in the Achenbach system of Empirically Bases Assessment. Results revealed that the prevalence of PTSD related to Typhoon Morakot was 25.8%. Adolescents who were female, had PTSD related to previous traumatic events before Typhoon Morakot, had more exposure experiences, were physically injured, or had family member in same household died or seriously injured were more likely to have the diagnoses of PTSD. Meanwhile, adolescents with PTSD had more severe depression, internalizing, externalizing, social, thought, and attention problems than those without PTSD. Our findings indicate that specialized trauma services are needed for these youngsters to lessen prolonged vulnerabilities.
