The present study compared preexisting groups of medicated and non-medicated children aged 8—13 years, with a primary diagnosis of an anxiety disorder, participating in a 12-session, manualized cognitive-behavior therapy group (GCBT). Of the 42 children, 13 (31%) were concurrently treated with Selective Serotonin Reuptake Inhibitors (SSRIs) for anxiety while they attended group treatment. Treatment outcomes for these medicated children were compared to those of children who were not on any medications for anxiety. Results suggested that both groups showed a significant decrease in their anxiety symptoms from pre- to post-treatment and from pre-treatment to 4-month follow-up, based on both child- and parent-report. No significant differences in anxiety symptoms were found between the medicated and non-medicated groups at pre-, post-, or 4-month follow-up, suggesting that the two groups benefited similarly from GCBT.
