The overall goal of this research is to elucidate the neural bases of two specific forms of emotion regulation - cognitive regulation (CR) and attention regulation (AR). CR and AR are thought to be important mechanisms underlying therapeutic change associated with Cognitive-Behavioral Therapy (CBT) and Mindfulness-Based Stress Reduction (MBSR) for generalized Social Anxiety Disorder (SAD). We seek to test whether changes in CR and AR underlie the therapeutic effects of CBT and MBSR, which have been shown in the clinical science literature to be effective treatments for SAD. We will examine CR and AR in healthy controls (HCs) and in participants with generalized SAD at baseline, as well as in participants with SAD after they have completed a randomized controlled trial (RCT) with three treatment arms: CBT, MBSR, or Waitlist (WL). This work will address 3 aims: Aim 1 will examine the efficacy of CR and AR in individuals with SAD versus HCs; Aim 2 will investigate the immediate and longer-term impact of CBT versus MBSR for SAD; and Aim 3 will examine treatment-related changes in CR and AR and test whether these changes mediate the effects of CBT versus MBSR. The broad, long-term objective of this research is to contribute to advances in clinical interventions targeting individuals suffering from SAD, as well as a wide range of other anxiety and mood disorders.
|Study Type :||Interventional (Clinical Trial)|
|Actual Enrollment :||108 participants|
|Intervention Model:||Single Group Assignment|
|Intervention Model Description:||To investigate treatment outcome and mediators of Cognitive-Behavioral Group Therapy (CBGT) vs. Mindfulness-Based Stress Reduction (MBSR) vs. Waitlist (WL) in patients with generalized social anxiety disorder (SAD), unmedicated patients with a primary diagnosis of Social Anxiety Disorder (SAD) will be randomized to CBGT vs. MBSR vs. WL and will complete assessments at baseline, post-treatment/WL, and at 1-year follow-up, including the Liebowitz Social Anxiety Scale - Self-Report (primary outcome; Liebowitz, 1987) as well as measures of treatment-related processes.|

Active Comparator: Cognitive Behavioral Group Therapy
Cognitive behavioral group therapy (CBGT) will be delivered by two Ph.D. clinical psychologists trained by Dr. Richard Heimberg to implement his CBGT for SAD (Heimberg & Becker, 2002). Groups of six individuals will meet for 12 sessions of 2.5 hours each. The participants will also use selected portions of the client workbook developed by (Hope, Heimberg, & Turk, 2010) to supplement relevant portions of the protocol. The treatment will be comprised of four major components: (1) psychoeducation and orientation to CBGT; (2) cognitive restructuring skills; (3) graduated exposure to feared social situations, within session and as homework; and (4) relapse prevention and termination. Further details of the treatment are available elsewhere (Heimberg & Becker, 2002).
Behavioral: Cognitive Behavioral Group Therapy
Cognitive Behavioral Group Therapy for social anxiety disorder is a 12-week treatment that involves psychoeducation, cognitive restructuring and exposure to social situations.
Other Name: CBGT
Active Comparator: Mindfulness-Based Stress Reduction
MBSR will follow the standard curriculum outline compiled in 1993 by Jon Kabat-Zinn except that the one-day meditation retreat will be converted to four additional weekly group sessions between the standard class 6 and 7 so that there will be 12 weekly 2.5 hour sessions. This will be done to match the CBGT protocol in duration and time. The MBSR intervention will be delivered by a University of Massachusetts Center for Mindfulness certified MBSR instructor with more than 30 years of teaching experience. To support the practice, each participant will be given A Mindfulness-Based Stress Reduction Workbook (Stahl & Goldstein, 2010), which includes descriptions of mindfulness exercises together with pre-recorded audio files to support ongoing practice.
Behavioral: Mindfulness-Based Stress Reduction
Mindfulness-Based Stress Reduction will be completed in 12 weeks in the study and includes enhancing one's awareness non-judgmentally by focusing on the present moment through the use of mindfulness meditation.
Other Name: MBSR
No Intervention: Waitlist Control
This will be a delayed treatment arm. Participants randomized to the waitlist control group will be re-randomized after completing the no treatment period of 12 weeks to CBGT or MBSR with equal probability.
- Changes in Liebowitz Social Anxiety Scale (LSAS) [ Time Frame: from baseline to 1- year following treatment ]The Liebowitz Social Anxiety Scale (LSAS) is a self-report questionnaire which assesses the severity of social anxiety symptoms (Fresco et al., 2001; Liebowitz, 1987). Respondents are asked to rate their level of fear and avoidance to 11 social interaction situations and 13 performance situations. A 4-point Likert-type scale is used for ratings of fear and of avoidance, with a range from 0 (none and never, respectively) to 3 (severe and usually, respectively) for each situation during the past week. Ratings are summed for a total LSAS-SR score (range 0 to 144). The LSAS-SR has demonstrated good reliability and construct validity (Rytwinski et al., 2009).
