GCBT is a child-focused treatment intervention with parental involvement, for children with overanxious disorder, social phobia, and avoidant disorder. The key therapeutic procedure in this intervention is exposure to anxious-phobic objects or events, with contingency management and self-control training as additional therapeutic strategies. In the group format, these strategies are generally sequenced between education and application with the parent receiving training on a specific strategy and applying it to the child, then the child receiving training and applying the strategy him or herself. A randomized clinical trial conducted in 1999 evaluated the therapeutic efficacy of this program versus a wait-list control condition. The study found that 64% of the children in GCBT were recovered at posttreatment (i.e., no longer met primary diagnoses) compared with 13% of the children in the control condition. In addition, 82% of the participants showed clinically significant improvement at posttreatment compared with only 9% in the control condition. An improvement was also observed for ratings of disorder severity and for child- and parent-completed questionnaire measures. A consistent trend for treatment gains was found at the 3-month and 6-month follow-ups. Additionally, participants who were not recovered continued to show improvement into the 12-month follow-ups. The pattern for all of the child- and parent-completed measures similarly indicated a continued reduction in degree and severity of anxious symptoms from posttreatment to the 3-month follow-up, with improvements maintained at 6 and 12 months.
