title: Effectiveness of cognitive behavioural group therapy for social phobia in a community clinic: a benchmarking study.
abstract: This study used a benchmarking strategy to investigate the transportability of cognitive behavioural group therapy (CBGT) for social phobia to a community mental health clinic. The influence of common exclusion criteria on effect sizes was also examined. Patients (N=153) attended seven 4-h sessions of CBGT, which resulted in significant reductions in symptoms of social anxiety and depression. Effect sizes compared favourably to previous efficacy and effectiveness studies of both group and individual treatment. More than half of the treatment completers achieved reliable change. One-third achieved clinically significant change (CSC) on the Social Phobia Scale and the Beck Depression Inventory, but fewer achieved CSC on the Social Interaction and Anxiety Scale. Restricting the sample on the basis of depression symptoms, age above or below 50 years, comorbidity, alcohol problems, or student status did not significantly moderate effect sizes for social anxiety. It is concluded that CBGT is effective within community mental health clinics.
