Imagery-enhanced cognitive behavioural group therapy for social anxiety disorder: a pilot study

Cognitive behavioural group therapy (CBGT) for social anxiety disorder (SAD) is efficacious and effective, however a substantial proportion of patients remain in the clinical range so treatment innovations are required. Research suggests that working within the imagery mode may be more emotionally potent than traditional verbal-linguistic strategies. This study piloted an imagery-enhanced CBGT (IE-CBGT) protocol for SAD. It was hypothesised that IE-CBGT would be acceptable to patients, demonstrate large effect sizes, and compare favourably to historical controls who completed CBGT without the imagery-enhancements. Patients (N=19) were consecutive referrals to a community clinic specialising in anxiety and mood disorders. Primary outcomes were self-reported performance and social interaction anxiety. IE-CBGT was highly acceptable to patients with high attendance and completion rates. Effect sizes were large by mid-treatment and very large at post-treatment and follow-up. A high proportion of patients achieved reliable change. Outcomes compared favourably to published group and individual treatments for SAD but larger randomised controlled trials are now required.
