Appropriate Number of Treatment Sessions in Virtual Reality-Based Individual Cognitive Behavioral Therapy for Social Anxiety Disorder

Virtual reality (VR) was introduced to maximize the effect of cognitive behavioral therapy (CBT) by efficiently performing exposure therapy. The purpose of this study was to find out whether VR-based individual CBT with relatively few treatment sessions is effective in improving social anxiety disorder (SAD). This therapy was applied to 115 patients with SAD who were retrospectively classified into 43 patients who completed the nine or 10 sessions normally (normal termination group), 52 patients who finished the sessions early (early termination group), and 20 patients who had extended the sessions (session extension group). The Brief Fear of Negative Evaluation Scale (BFNE) scores tended to decrease in all groups as the session progressed, and the slope of decrease was the steepest in the early termination group and the least steep in the session extension group. Severity of social anxiety in the last session and symptom reduction rate showed no significant group difference. Our findings suggest that short-term VR-based individual CBT of nine to 10 sessions may be effective. When the therapeutic effect is insufficient during this period, the additional benefit may be minimal if the session is simply extended. The improvement in the early termination group suggests that even shorter sessions of five or six can also be effective.

Background: Psychoanalytic theory and some empirical research suggest the working alliance follows a “rupture and repair” pattern over the course of therapy, but given its emphasis on collaboration, cognitive behavioral therapy may yield a different trajectory. Aims: The current study compares the trajectory of the working alliance during two types of cognitive behavioral therapy for social anxiety disorder – virtual reality exposure therapy (VRE) and exposure group therapy (EGT), one of which (VRE) has been proposed to show lower levels of working alliance due to the physical barriers posed by the technology (e.g. no eye contact with therapist during exposure). Method: Following randomization, participants (N = 63) diagnosed with social anxiety disorder received eight sessions of manualized EGT or individual VRE and completed a standardized self-report measure of working alliance after each session. Results: Hierarchical linear modeling showed overall high levels of working alliance that changed in rates of growth over time; that is, increases in working alliance scores were steeper at the beginning of therapy and slowed towards the end of therapy. There were no differences in working alliance between the two treatment groups. Conclusion: Results neither support a rupture/repair pattern nor the idea that the working alliance is lower for VRE participants. Findings are consistent with the idea that different therapeutic approaches may yield different working alliance trajectories.
