A follow-up study on treatment effects of cognitive-behavioral therapy on social anxiety disorder: Impact of COVID-19 fear during post-lockdown period.

ABSTRACT

There is a paucity of research on the role of COVID-19 related fear and lockdown on social anxiety disorder (SAD). In a follow-up study during post-lockdown period, we compared social anxiety of individuals with SAD who received cognitive-behavioral therapy (CBT) versus psychoeducational-supportive therapy (PST) before the COVID-19 pandemic, and the impact of COVID-19 related fear. Social anxiety severity was rated by the Social Phobia Inventory (SPIN) at pre-intervention, post-intervention, and post-lockdown periods. Fear of COVID-19 was assessed during the post-lockdown period. The treatment effects in the CBT group (n = 33) were significantly better than the PST group (n = 32) at post-intervention; this was maintained at 14-months following intervention despite COVID-related lockdown. In the PST group, there was no change following the intervention; and the social phobia increased after lockdown. The CBT group had significantly less COVID-19 related fear than the PST group. Social anxiety was positively correlated with fear of COVID-19; and individuals with comorbidities had significantly more fear. Using the hierarchical multiple regression, SPIN post-intervention, COVID-19 fear, and duration of SAD predicted social anxiety severity during the post-lockdown period. In conclusion, the effect of CBT for SAD was maintained through lockdown and was associated with significantly less COVID-19 related fear.
