Feasibility of trauma-focused cognitive behavioral therapy for traumatized children in Japan: a Pilot Study

Background: Trauma-focused cognitive behavioral therapy is used to treat children who have experienced traumatic events and suffer from trauma-related disorders. Its effectiveness has been demonstrated in several randomized controlled studies. However, most of these studies have been performed in the United States, with few studies conducted in Asian countries. Therefore, we aimed to evaluate the feasibility of trauma-focused cognitive behavioral therapy in children who have experienced traumatic events and who suffer from trauma-related disorders in Japan. Findings: Thirty-five traumatized children (mean age = 10.9 years; range = 3-17 years; 74.3% girls) who received trauma-focused cognitive behavioral therapy were included. The effectiveness of the program was evaluated in each case using the University of California at Los Angeles Post-Traumatic Stress Disorder Reaction Index for DSM-IV for trauma-related symptoms and the Children's Global Assessment Scale for social functioning. Pre-and post-treatment outcome measures were analyzed using two-tailed paired t tests. The results for 35 participants indicate that post-traumatic stress symptoms were significantly improved following therapy [t(35) = 8.27; p < 0.01], whereas the assessment of social functioning supported the effectiveness of the program [t(35) = -14.68; p < 0.01]. The pre- to post-treatment effect sizes (Glass's delta) were 1.24 for the University of California at Los Angeles Post-Traumatic Stress Disorder Reaction Index and 1.96 for the Children's Global Assessment Scale. Conclusions: Our findings indicate that trauma-focused cognitive behavioral therapy is feasible for treating traumatized children of an Asian population. We discuss the implications of this result for clinical practice and future research.
