    ABSTRACT: The efficacy and partial effectiveness of child-focused versus family-focused cognitive-behavioral therapy (CBT) for clinically anxious youths was evaluated, in particular in relation to parental anxiety disorders and child's age. Clinically referred children with anxiety disorders (N = 128) and their parents were randomly assigned to child or family CBT and evaluated at pretreatment, posttreatment, and 3-month follow-up. Twenty-five families were measured before and after a 2- to 3-month waitlist period. None of the waitlisted children recovered from their anxiety disorders. In contrast, 41% of the treated children no longer met criteria for any anxiety disorder after CBT, and 52% demonstrated continued improvement at the 3-month follow-up. Significantly more children were free of anxiety disorders (53%) in the child CBT condition compared with family CBT condition (28%) at posttreatment, whereas at 3-month follow-up, the superior effect of child CBT was no longer significant. Similar results were obtained from the questionnaire measures. Both child and family CBT were less effective if parents had an anxiety disorder themselves. On some of the measures, child CBT was superior if parents had anxiety disorders themselves, whereas family CBT was superior if parents had no anxiety disorders. Finally, younger children had better outcomes than older children, regardless of the treatment condition. Overall, child CBT seems slightly more beneficial than family CBT. Because this study was conducted in a clinical setting with clinically referred children, results indicate partial effectiveness for child CBT.

    ABSTRACT: The objective of this study was to investigate the cost-effectiveness of family cognitive-behavioral therapy (CBT) compared with individual CBT in children with anxiety disorders. Clinically anxious children (aged 8-18 years) referred for treatment were randomly assigned to family or individual CBT and were assessed pre-treatment, post treatment, and at 3 months and 1 year after treatment. Cost-effectiveness ratios were calculated expressing the incremental costs per anxiety-free child and the incremental costs per Quality Adjusted Life Year (QALY) for the referred child. Neither societal costs nor effectiveness were significantly different between individual and family CBT. However, the point estimates of the cost-effectiveness ratios resulted in dominance for individual CBT, indicating that individual CBT is more effective and less costly than family CBT. These results were confirmed by bootstrap analyses and cost-effectiveness acceptability curves. Several secondary and sensitivity analyses showed that the results were robust. It can be concluded that family CBT is not a cost-effective treatment for clinically anxious children, compared with individual CBT.
