No differences between group versus individual treatment of childhood anxiety disorders in a randomised clinical trial.

Background: The present study compares an individual versus a group format in the delivery of manualised cognitive-behavioural therapy (FRIENDS) for children with anxiety disorders. Clinically referred children (aged 8 to 12) diagnosed with Separation Anxiety Disorder (n = 52), Generalised Anxiety Disorder (n = 37), Social Phobia (n = 22) or Specific Phobia (n = 16) were randomly assigned to individual (n = 65) or group (n = 62) treatment.

Method: Analyses were conducted separately for the intent-to-treat sample and the sample of children who completed treatment. Analyses included chi-square comparisons and regression analyses with treatment format as a predictor.

Results: Forty-eight percent of the children in the individual versus 41% in the group treatment were free of any anxiety disorder at post-treatment; 62% versus 54% were free of their primary anxiety disorder. Regression analyses showed no significant difference in outcome between individual and group treatment.

Conclusions: Children improved in both conditions. Choice between treatments could be based on pragmatic considerations such as therapeutic resources, referral rates, and the preference of the parents and the child.
