This study examined changes in post-event processing (PEP), metacognitions, and symptoms of social anxiety and depression following cognitive behavioral group therapy for social phobia (N=61). Social anxiety, depression symptoms and PEP all significantly reduced following treatment. Reductions in PEP were associated with reductions in symptoms of social anxiety, but not depression. Metacognitions were also less strongly endorsed following treatment, with the exception of positive metacognitions. Interestingly, however, changes in metacognitions were generally associated with reductions in depression and not social anxiety. Theoretical and clinical implications as well as future research directions are discussed.
