Treatment of social approach processes in adults with social anxiety disorder

Despite the social impairment associated with social anxiety disorder (SAD), little research has examined the impact of treatment on positive relational functioning. Accordingly, the authors conducted a treatment outcome study to evaluate a cognitive behavior therapy (CBT) regimen augmented by a relational focus (CBT-R) relative to a graduated exposure-applied relaxation (GEAR) regimen and wait list (WL) control. To examine the mechanism(s) that underlies treatment effects, they used structural equation modeling (SEM) to evaluate two potential mediators, change in judgment biases and in safety behaviors.

Treatment-seeking adults who met SAD diagnostic criteria (n = 100; 50% women; mean age = 32.9 years.; 36% ethnic minority) were randomly assigned to CBT-R, GEAR, or WL. CBT-R and GEAR participants received 14 group treatment sessions. Social initiation, relationship satisfaction, and a SAD symptom composite were assessed at pre- and postassessment, and 6- and 12-month follow-ups.

Intent-to-treat multilevel modeling analyses indicated that the CBT-R regimen resulted in significantly greater improvement relative to GEAR on relationship satisfaction and SAD symptoms. SEM results revealed that change in safety behaviors partially mediated the superior performance of CBT-R on both variables with confidence intervals set at .90.

These findings indicate that CBT-based regimens can improve social approach processes in individuals with SAD and that safety behavior reduction contributes to positive outcomes. (PsycINFO Database Record
