Cognitive-behavioral group therapy versus group psychotherapy for social anxiety disorder among college students: a randomized controlled trial.

OBJECTIVE: In this randomized controlled trial, cognitive-behavioral group therapy (CBGT) for social anxiety disorder (SAD) was compared to group psychotherapy (GPT), a credible, structurally equivalent control condition that included only nonspecific factors of group treatment (such as group dynamics). METHODS: Participants were 45 college students at the University of Colorado with a primary diagnosis of SAD. Each treatment condition comprised eight group sessions lasting 2 hr each. Independent assessors (blind to treatment assignment) assessed participants at baseline and posttreatment with the Clinical Global Impression Scale (CGI) and the Liebowitz Social Anxiety Scale (LSAS). RESULTS: Both treatments were found to be equally credible. There were five noncompleters in the CBGT condition (21.7%) and only one in the GPT condition (4.3%). There were no statistically significant differences posttreatment (controlling for pretreatment scores) between the two treatment conditions, and both treatments were found to be efficacious. Effect sizes for CBGT were similar to earlier studies, and adherence ratings revealed excellent adherence. CONCLUSIONS: Treatment of SAD appears to be moving toward individual CBT, partly because of high attrition rates and underutilization of group dynamics in group CBT. However, group therapy has unique therapeutic ingredients, and it may be too early to give up on group treatment altogether. Discussion of these findings included future directions with this treatment modality, especially whether these two types of group treatment could be combined and whether such combination might serve to decrease attrition, enhance efficacy, and facilitate dissemination.

A placebo-controlled trial of phenelzine, cognitive behavioral group therapy, and their combination for social anxiety disorder.

CONTEXT: Medication and cognitive behavioral treatment are the best-established treatments for social anxiety disorder, yet many individuals remain symptomatic after treatment. OBJECTIVE: To determine whether combined medication and cognitive behavioral treatment is superior to either monotherapy or pill placebo. DESIGN: Randomized, double-blind, placebo-controlled trial. SETTING: Research clinics at Columbia University and Temple University. PARTICIPANTS: One hundred twenty-eight individuals with a primary DSM-IV diagnosis of social anxiety disorder. INTERVENTIONS: Cognitive behavioral group therapy (CBGT), phenelzine sulfate, pill placebo, and combined CBGT plus phenelzine. MAIN OUTCOME MEASURES: Liebowitz Social Anxiety Scale and Clinical Global Impression (CGI) scale scores at weeks 12 and 24. RESULTS: Linear mixed-effects models showed a specific order of effects, with steepest reductions in Liebowitz Social Anxiety Scale scores for the combined group, followed by the monotherapies, and the least reduction in the placebo group (Williams test = 4.97, P < .01). The CGI response rates in the intention-to-treat sample at week 12 were 9 of 27 (33.3%) (placebo), 16 of 34 (47.1%) (CBGT), 19 of 35 (54.3%) (phenelzine), and 23 of 32 (71.9%) (combined treatment) (chi(2)(1) = 8.76, P < .01). Corresponding remission rates (CGI = 1) were 2 of 27 (7.4%), 3 of 34 (8.8%), 8 of 35 (22.9%), and 15 of 32 (46.9%) (chi(2)(1) = 15.92, P < .01). At week 24, response rates were 9 of 27 (33.3%), 18 of 34 (52.9%), 17 of 35 (48.6%), and 25 of 32 (78.1%) (chi(2)(1) = 12.02, P = .001). Remission rates were 4 of 27 (14.8%), 8 of 34 (23.5%), 9 of 35 (25.7%), and 17 of 32 (53.1%) (chi(2)(1) = 10.72, P = .001). CONCLUSION: Combined phenelzine and CBGT treatment is superior to either treatment alone and to placebo on dimensional measures and on rates of response and remission.

Traumatic and socially stressful life events among persons with social anxiety disorder.

This study examined the frequency of reexperiencing, avoidance, and hyperarousal symptoms most often associated with posttraumatic stress disorder (PTSD) among 45 persons with social anxiety disorder and 30 nonanxious controls in response to an extremely stressful social event (which did not satisfy DSM-IV's PTSD Criterion A). Avoidance and hyperarousal in response to reminders of socially stressful events were common among patients; more than one-third would have met criteria for PTSD if these events satisfied DSM-IV PTSD Criterion A. Frequency of this PTSD-like symptom pattern did not differ among patients who did and did not experience another event that did satisfy PTSD Criterion A. Implications of these findings for the treatment of social anxiety disorder are discussed.

The Internet: home to a severe population of individuals with social anxiety disorder?

The current study sought to understand better the psychological characteristics of socially anxious individuals who seek information on the internet about social anxiety disorder and its treatment. Participants were 434 individuals who responded to an internet-based survey linked to the website of an anxiety specialty clinic. Using established cut-off scores, 92% of the sample met criteria for social anxiety disorder. Internet survey respondents who met these criteria reported greater severity of and impairment due to social anxiety than a treatment-seeking sample of persons with social anxiety disorder. Nevertheless, only about one-third of these internet respondents reported having received psychotherapy, and a similar percentage reported having received pharmacotherapy. Those with the most severe social interaction anxiety and who spent the most time interacting on the internet endorsed positive effects of internet use. However, a significant number of negative effects also were endorsed.

Comorbid anxiety and mood disorders among persons with social anxiety disorder.

Axis I comorbidity is associated with greater severity of social anxiety disorder. However, the differential effects of comorbid mood and anxiety disorders on symptom severity or treatment outcome have not been investigated. We evaluated 69 persons with uncomplicated social anxiety disorder, 39 persons with an additional anxiety disorder, and 33 persons with an additional mood disorder (with or without additional anxiety disorders). Those with comorbid mood disorders reported greater duration of social anxiety than those with uncomplicated social anxiety disorder. They were also judged, before and after 12 weeks of cognitive-behavioral group treatment and at follow-up, to be more severely impaired than those with no comorbid diagnosis. In contrast, persons with comorbid anxiety disorders were rated as more impaired than those with no comorbid diagnosis on only a single measure. Type of comorbid diagnosis did not result in differential rates of improvement of social anxiety disorder.
