The aim of this study is to evaluate the effectiveness of Triple P Positive Parenting Program, which has been shown to be effective in reducing children’s behavior problems in a variety of populations, on childhood anxiety disorders. This is an open-labelled continuation study of the randomized, single-blinded, controlled trial which is done 4 months after the intervention. A total of 50 subjects ages between 8 and 12 diagnosed with anxiety disorder were enrolled to the open-labelled phase of the study. The two groups were compared right before and 4 months after the implementation with various questionnares which measured the children’s amotional and behavioral problems and anxiety severity and parental general well being and axiety were also evaluated. Children’s general anxiety level and anxiety disorder severity of intervention group were significantly lower than waiting list group. In this study, it is shown that parental anxiety and general well being were also improved. Our results suggest that Triple P may be an effective and useful method of treatment for anxious children. Large sample sized studies are needed.
