Randomized Controlled Trial of Group Cognitive Behavioural Therapy for Post-Traumatic Stress Disorder in Children and Adolescents Exposed to Tsunami in Thailand.

BACKGROUND Post-traumatic stress disorder (PTSD) is a common and debilitating consequence of natural disaster in children and adolescents. Accumulating data show that cognitive behavioural therapy (CBT) is an effective treatment for PTSD. However, application of CBT in a large-scale disaster in a setting with limited resources, such as when the tsunami hit several Asian countries in 2004, poses a major problem. AIMS This randomized controlled trial aimed to test for the efficacy of the modified version of CBT for children and adolescents with PSTD. METHOD Thirty-six children (aged 10-15 years) who had been diagnosed with PSTD 4 years after the tsunami were randomly allocated to either CBT or wait list. CBT was delivered in 3-day, 2-hour-daily, group format followed by 1-month posttreatment self-monitoring and daily homework. RESULTS Compared to the wait list, participants who received CBT demonstrated significantly greater improvement in symptoms of PTSD at 1-month follow-up, although no significant improvement was observed when the measures were done immediately posttreatment. CONCLUSIONS Brief, group CBT is an effective treatment for PTSD in children and adolescents when delivered in conjunction with posttreatment self-monitoring and daily homework.
