Effectiveness of cognitive behavioral therapy on social anxiety disorder: A comparative study

Both cognitive behavior therapy (CBT) and paroxetine (PX) are the preferred treatments for social anxiety disorder (SAD). However, in literature, there have been divided opinions for the efficacy of the combination of these treatments. This study intended to evaluate whether the combination of CBT and PX would be superior to monotherapy of PX in the treatment of SAD.

This was a single centre, rater-blind, non randomised study which included 40 consenting adult participants who received CBT+PX or PX only. The Liebowitz Social Anxiety Scale, Social Interaction Anxiety Scale, and Brief Fear of Negative Evaluation scale (BFNE) were assessed at baseline (0 weeks), immediate posttreatment (16-18 weeks for CBT + PX and 16-20 weeks for PX only), and at follow-ups 2 months after posttreatment.

Both the treatment groups have a statistically significant difference in mean scores in all outcome measures in posttreatment and follow-up stages compared with pretreatment scores. However, CBT + PX has a better treatment and maintenance gain as compared to PX alone in the posttreatment and follow-up stages.

In SAD management, combinations of CBT + PX are superior to PX alone, and the treatment gains are also better maintained in former than latter.
