Evaluation of Cognitive Behavioral Therapy vs Mindfulness Meditation in Brain Changes During Reappraisal and Acceptance Among Patients With Social Anxiety Disorder: A Randomized Clinical Trial.

Importance: Cognitive behavioral group therapy (CBGT) and mindfulness-based stress reduction (MBSR) are thought to help patients with social anxiety disorder (SAD) via distinct emotion-regulation mechanisms. However, no study has compared the effects of CBGT and MBSR on brain and negative emotion indicators of cognitive reappraisal and acceptance in patients with SAD. Objective: To investigate the effects of CBGT and MBSR on reappraisal and acceptance in patients with SAD and to test whether treatment-associated brain changes are associated with social anxiety symptoms 1 year posttreatment. Design, Setting, and Participants: In this randomized clinical trial, a total of 108 unmedicated adults diagnosed with generalized SAD were randomly assigned to 12 weeks of CBGT, MBSR, or waitlist. The final sample included 31 patients receiving CBGT, 32 patients receiving MBSR, and 32 waitlist patients. Data were collected at the psychology department at Stanford University from September 2012 to December 2014. Data were analyzed from February 2019 to December 2020. Interventions: CBGT and MBSR. Main Outcomes and Measures: Changes in self-reported negative emotion and functional magnetic resonance imaging (fMRI) blood oxygen level-dependent (BOLD) signal within an a priori-defined brain search region mask derived from a meta-analysis of cognitive reappraisal and attention regulation 1 year posttreatment. Results: Of 108 participants, 60 (56%) were female. The mean (SD) age was 32.7 (8.0) years. Self-reported race and ethnicity data were collected to inform the generalizability of the study to the wider population and to satisfy the requirements of the National Institutes of Health. From the categories provided by the National Institutes of Health, 47 participants selected White (43.5%), 42 selected Asian (38.9%) 10 selected Latinx (9.3%), 1 selected Black (1%), 1 selected Native American (1%), and 7 selected more than 1 race (6.5%). CBGT and MBSR were associated with a significant decrease in negative emotion (partial η2 range, 0.38 to 0.53) with no significant between-group differences when reacting (ß, -0.04; SE, 0.09; 95% CI, -0.11 to 0.08; t92 = -0.37; P = .71), reappraising (ß, -0.15; SE, 0.09; 95% CI, -0.32 to 0.03; t92 = -1.67; P = .10), or accepting (ß, -0.05; SE, 0.08; 95% CI, -0.20 to 0.11; t92 = -0.59; P = .56). There was a significant increase in BOLD percentage signal change in cognitive and attention-regulation regions when reappraising (CBGT = 0.031; MBSR = 0.037) and accepting (CBGT = 0.012; MBSR = 0.077) negative self-beliefs. CBGT and MBSR did not differ in decreased negative emotion and increased reappraisal and acceptance BOLD responses. Reappraisal-associated MBSR (vs CBGT) negative emotions and CBGT (vs MBSR) brain responses were associated with social anxiety symptoms 1 year posttreatment. Conclusions and Relevance: The results of this study suggest that CBGT and MBSR may be effective treatments with long-term benefits for patients with SAD that recruit cognitive and attention-regulation brain networks. Despite contrasting models of therapeutic change, CBT and MBSR may both enhance reappraisal and acceptance emotion regulation strategies.

The moderating effects of anger suppression and anger expression on cognitive behavioral group therapy and mindfulness-based stress reduction among individuals with social anxiety disorder.

BACKGROUND: . Cognitive-behavioral therapy and mindfulness-based stress reduction (MBSR) are two prominent evidence-based treatments for social anxiety disorder (SAD). It is not clear, however, whether outcomes of these two treatments are moderated by similar factors. For example, whereas anger suppression and anger expression each predict outcomes in cognitive- behavioral group therapy (CBGT), it is unknown whether they differentially influence outcomes in CBGT versus MBSR. METHODS: . One hundred eight participants with SAD were randomized to CBGT, MBSR or Waitlist (WL). WL participants were later randomized to CBGT or MBSR, and their data were combined with data from those originally randomized to CBGT or MBSR. Anger suppression and anger expression were assessed at pre-treatment, and social anxiety was assessed at pre-treatment, post-treatment, and every 3 months throughout a 12-month follow-up period. RESULTS: . From pre- to post-treatment, higher anger suppression was associated with significantly greater reduction in social anxiety in CBGT compared with MBSR. From post-treatment through follow-up, higher anger expression was associated lesser reduction in social anxiety in MBSR but not in CBGT. LIMITATIONS: . Data are limited by sole reliance on self-report and it is unclear whether these findings generalize beyond group-based interventions. CONCLUSIONS: . Individuals with SAD who are higher in anger suppression and/or expression might be better suited to CBGT than MBSR.

Reductions in social anxiety during treatment predict lower levels of loneliness during follow-up among individuals with social anxiety disorder.

INTRODUCTION: Individuals with social anxiety disorder (SAD) are at elevated risk of loneliness, yet little research has examined loneliness in this population. Cognitive-behavioral group therapy (CBGT) and mindfulness-based stress reduction (MBSR) have demonstrated efficacy in treating SAD, yet research has not examined whether they lead to reductions in loneliness. METHODS: This sample comprised 108 individuals with SAD who were randomized to CBGT, MBSR, or a waitlist control (WL); WL participants were re-randomized to CBGT or MBSR following WL. Assessments were completed pre- and post-treatment, and 3-, 6-, 9-, and 12-month follow-up assessments. RESULTS: Compared to WL, individuals in CBGT and MBSR were less lonely at post-treatment; there was no difference between treatments after treatment or during follow-up. Greater reductions in social anxiety from pre- to post-treatment predicted lower levels of loneliness during follow-up. Greater reductions in loneliness from pre- to post-treatment also predicted lower levels of social anxiety during follow-up. DISCUSSION: Individuals who experience reductions in their social anxiety during treatment may also feel less lonely following treatment. Reductions in loneliness also lead to improvements in social anxiety. Future research should continue to examine the relationship between social anxiety and loneliness and how interventions for SAD may help reduce loneliness.

Changes in Empathy Mediate the Effects of Cognitive-Behavioral Group Therapy but Not Mindfulness-Based Stress Reduction for Social Anxiety Disorder.

Social anxiety disorder (SAD) has been shown to be associated with difficulty in the ability to vicariously share others' positive emotions (positive affective empathy). Mixed evidence also suggests potentially impaired recognition of the positive and negative emotions of others (cognitive empathy) and impaired or enhanced sharing of the negative emotions of others (negative affective empathy). Therefore, we examined whether two efficacious treatments for SAD, cognitive-behavioral group therapy (CBGT) and mindfulness-based stress reduction (MBSR), improve empathy in SAD relative to a wait-list condition and whether improvements in empathy mediate improvements in social anxiety. In the context of a randomized controlled trial, participants with SAD completed an empathy task at baseline, posttreatment/wait-list (N = 81), and 1-year follow-up (N = 37). Relative to both MBSR and wait-list, CBGT resulted in significant improvements in positive affective empathy. CBGT-related changes in positive affective empathy also mediated improvements in social anxiety at both posttreatment/wait-list and at 1-year follow-up. Other indices of empathy did not change differentially across the three conditions. Therefore, one way in which CBGT may specifically confer benefits to individuals with SAD is through increasing their ability or willingness to share in the positive emotions of others.

Do sudden gains predict treatment outcome in social anxiety disorder? Findings from two randomized controlled trials.

OBJECTIVE: Sudden gains (SGs) have been found to occur during randomized controlled trials (RCTs) for social anxiety disorder (SAD). Evidence is mixed whether SGs relate to treatment outcome in SAD. We examined SGs in two RCTs for SAD. METHOD: Study 1 (N = 68) examined SGs in individual cognitive-behavioral therapy (CBT), and Study 2 (N = 100) compared SGs in group CBT and Mindfulness-Based Stress Reduction (MBSR). Weekly ratings of social anxiety were used to calculate SGs. The Liebowitz Social Anxiety Scale-Self-Report and the Social Interaction Anxiety Scale were completed at pretreatment, posttreatment, and follow-up to assess outcome. RESULTS: In Study 1, 17.6% of participants experienced a SG. Participants with SGs started and ended treatment with lower social anxiety. SGs were not associated with greater decreases in social anxiety from pre-to posttreatment or 12-month follow-up. In Study 2, SGs occurred in 27% of participants and at comparable rates in MBSR and group CBT. SGs were not associated with changes in social anxiety during treatment in either condition. CONCLUSION: SGs occurred during treatment for SAD. In both RCTs, participants improved regardless of experiencing a SG, suggesting that SGs are not predictive of greater improvement during treatment for SAD.

Emotional clarity and attention to emotions in cognitive behavioral group therapy and mindfulness-based stress reduction for social anxiety disorder.

We examined (1) differences between controls and patients with social anxiety disorder (SAD) in emotional clarity and attention to emotions; (2) changes in emotional clarity and attention to emotions associated with cognitive-behavioral group therapy (CBGT), mindfulness-based stress reduction (MBSR), or a waitlist (WL) condition; and (3) whether emotional clarity and attention to emotions moderated changes in social anxiety across treatment. Participants were healthy controls (n = 37) and patients with SAD (n = 108) who were assigned to CBGT, MBSR, or WL in a randomized controlled trial. At pretreatment, posttreatment, and 12-month follow-up, patients with SAD completed measures of social anxiety, emotional clarity, and attention to emotions. Controls completed measures at baseline only. At pretreatment, patients with SAD had lower levels of emotional clarity than controls. Emotional clarity increased significantly among patients receiving CBGT, and changes were maintained at 12-month follow-up. Emotional clarity at posttreatment did not differ between CBGT and MBSR or between MBSR and WL. Changes in emotional clarity predicted changes in social anxiety, but emotional clarity did not moderate treatment outcome. Analyses of attention to emotions were not significant. Implications for the role of emotional clarity in the treatment of SAD are discussed.

Trajectories of social anxiety, cognitive reappraisal, and mindfulness during an RCT of CBGT versus MBSR for social anxiety disorder.

Cognitive-Behavioral Group Therapy (CBGT) and Mindfulness-Based Stress Reduction (MBSR) are efficacious in treating social anxiety disorder (SAD). It is not yet clear, however, whether they share similar trajectories of change and underlying mechanisms in the context of SAD. This randomized controlled study of 108 unmedicated adults with generalized SAD investigated the impact of CBGT vs. MBSR on trajectories of social anxiety, cognitive reappraisal, and mindfulness during 12 weeks of treatment. CBGT and MBSR produced similar trajectories showing decreases in social anxiety and increases in reappraisal (changing the way of thinking) and mindfulness (mindful attitude). Compared to MBSR, CBGT produced greater increases in disputing anxious thoughts/feelings and reappraisal success. Compared to CBGT, MBSR produced greater acceptance of anxiety and acceptance success. Granger Causality analyses revealed that increases in weekly reappraisal and reappraisal success predicted subsequent decreases in weekly social anxiety during CBGT (but not MBSR), and that increases in weekly mindful attitude and disputing anxious thoughts/feelings predicted subsequent decreases in weekly social anxiety during MBSR (but not CBGT). This examination of temporal dynamics identified shared and distinct changes during CBGT and MBSR that both support and challenge current conceptualizations of these clinical interventions.

Group CBT versus MBSR for social anxiety disorder: A randomized controlled trial.

OBJECTIVE: The goal of this study was to investigate treatment outcome and mediators of cognitive-behavioral group therapy (CBGT) versus mindfulness-based stress reduction (MBSR) versus waitlist (WL) in patients with generalized social anxiety disorder (SAD). METHOD: One hundred eight unmedicated patients (55.6% female; mean age = 32.7 years, SD = 8.0; 43.5% Caucasian, 39% Asian, 9.3% Hispanic, 8.3% other) were randomized to CBGT versus MBSR versus WL and completed assessments at baseline, posttreatment/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. RESULTS: Linear mixed model analysis showed that CBGT and MBSR both produced greater improvements on most measures compared with WL. Both treatments yielded similar improvements in social anxiety symptoms, cognitive reappraisal frequency and self-efficacy, cognitive distortions, mindfulness skills, attention focusing, and rumination. There were greater decreases in subtle avoidance behaviors following CBGT than MBSR. Mediation analyses revealed that increases in reappraisal frequency, mindfulness skills, attention focusing, and attention shifting, and decreases in subtle avoidance behaviors and cognitive distortions, mediated the impact of both CBGT and MBSR on social anxiety symptoms. However, increases in reappraisal self-efficacy and decreases in avoidance behaviors mediated the impact of CBGT (vs. MBSR) on social anxiety symptoms. CONCLUSIONS: CBGT and MBSR both appear to be efficacious for SAD. However, their effects may be a result of both shared and unique changes in underlying psychological processes.

Pre-treatment social anxiety severity moderates the impact of mindfulness-based stress reduction and aerobic exercise.

UNLABELLED: We examined whether social anxiety severity at pre-treatment would moderate the impact of mindfulness-based stress reduction (MBSR) or aerobic exercise (AE) for generalized social anxiety disorder. MBSR and AE produced equivalent reductions in weekly social anxiety symptoms. Improvements were moderated by pre-treatment social anxiety severity. PRACTITIONER POINTS: Mindfulness-based stress reduction (MBSR) and aerobic exercise (AE) are effective in reducing symptoms of social anxiety. Pre-treatment social anxiety severity can be used to inform treatment recommendations. Both MBSR and AE produced equivalent reductions in weekly levels of social anxiety symptoms. MBSR appears to be most effective for patients with lower pre-treatment social anxiety symptom severity. AE appears to be most effective for patients with higher pre-treatment social anxiety symptom severity.

The role of emotion and emotion regulation in social anxiety disorder.

Many psychiatric disorders involve problematic patterns of emotional reactivity and regulation. In this review, we consider recent findings regarding emotion and emotion regulation in the context of social anxiety disorder (SAD). We first describe key features of SAD which suggest altered emotional and self-related processing difficulties. Next, we lay the conceptual foundation for a discussion of emotion and emotion regulation and present a common framework for understanding emotion regulation, the process model of emotion regulation. Using the process model, we evaluate the recent empirical literature spanning self-report, observational, behavioral, and physiological methods across five specific families of emotion regulation processes-situation selection, situation modification, attentional deployment, cognitive change, and response modulation. Next, we examine the empirical evidence behind two psychosocial interventions for SAD: cognitive behavioral therapy (CBT) and mindfulness-based stress reduction (MBSR). Throughout, we present suggestions for future directions in the continued examination of emotion and emotion regulation in SAD.

Changes in Positive Self-Views Mediate the Effect of Cognitive-Behavioral Therapy for Social Anxiety Disorder.

Social Anxiety Disorder (SAD) is thought to be characterized by maladaptive self-views. This study investigated whether (1) patients with SAD (n=75) differ at baseline from healthy controls (HC; n=43) in negative and positive self-views, (2) Cognitive-Behavioral Therapy (CBT) for SAD vs. waitlist control (WL) produces statistically and clinically significant changes in negative and positive self-views, (3) changes in self-views mediate the effect of CBT on social anxiety symptoms, and (4) changes in self-views during CBT related to social anxiety symptoms at 1-year post-CBT. As expected, patients endorsed more negative and fewer positive self-views than HC at baseline. Compared to WL, CBT yielded statistically and clinically significant changes, specifically, fewer negative and more positive self-views. Mediational analysis indicated that increased positive (but not reduced negative) self-views mediated the effect of CBT on social anxiety reduction. Correlational analyses determined that increased positive self-views were associated with social anxiety symptom reduction at 1-year-post-CBT.

A randomized trial of MBSR versus aerobic exercise for social anxiety disorder.

OBJECTIVE: Effective treatments for social anxiety disorder (SAD) exist, but additional treatment options are needed for nonresponders as well as those who are either unable or unwilling to engage in traditional treatments. Mindfulness-based stress reduction (MBSR) is one nontraditional treatment that has demonstrated efficacy in treating other mood and anxiety disorders, and preliminary data suggest its efficacy in SAD as well. METHOD: Fifty-six adults (52% female; 41% Caucasian; age mean [M] ± standard deviation [SD]: 32.8 ± 8.4) with SAD were randomized to MBSR or an active comparison condition, aerobic exercise (AE). At baseline and post-intervention, participants completed measures of clinical symptoms (Liebowitz Social Anxiety Scale, Social Interaction Anxiety Scale, Beck Depression Inventory-II, and Perceived Stress Scale) and subjective well-being (Rosenberg Self-Esteem Scale, Satisfaction with Life Scale, Self-Compassion Scale, and UCLA-8 Loneliness Scale). At 3 months post-intervention, a subset of these measures was readministered. For clinical significance analyses, 48 healthy adults (52.1% female; 56.3% Caucasian; age [M ± SD]: 33.9 ± 9.8) were recruited. MBSR and AE participants were also compared with a separate untreated group of 29 adults (44.8% female; 48.3% Caucasian; age [M ± SD]: 32.3 ± 9.4) with generalized SAD who completed assessments over a comparable time period with no intervening treatment. RESULTS: A 2 (Group) x 2 (Time) repeated measures analyses of variance (ANOVAs) on measures of clinical symptoms and well-being were conducted to examine pre-intervention to post-intervention and pre-intervention to 3-month follow-up. Both MBSR and AE were associated with reductions in social anxiety and depression and increases in subjective well-being, both immediately post-intervention and at 3 months post-intervention. When participants in the randomized controlled trial were compared with the untreated SAD group, participants in both interventions exhibited improvements on measures of clinical symptoms and well-being. CONCLUSION: Nontraditional interventions such as MBSR and AE merit further exploration as alternative or complementary treatments for SAD.

Effects of mindfulness-based stress reduction (MBSR) on emotion regulation in social anxiety disorder.

Mindfulness-based stress reduction (MBSR) is an established program shown to reduce symptoms of stress, anxiety, and depression. MBSR is believed to alter emotional responding by modifying cognitive-affective processes. Given that social anxiety disorder (SAD) is characterized by emotional and attentional biases as well as distorted negative self-beliefs, we examined MBSR-related changes in the brain-behavior indices of emotional reactivity and regulation of negative self-beliefs in patients with SAD. Sixteen patients underwent functional MRI while reacting to negative self-beliefs and while regulating negative emotions using 2 types of attention deployment emotion regulation-breath-focused attention and distraction-focused attention. Post-MBSR, 14 patients completed neuroimaging assessments. Compared with baseline, MBSR completers showed improvement in anxiety and depression symptoms and self-esteem. During the breath-focused attention task (but not the distraction-focused attention task), they also showed (a) decreased negative emotion experience, (b) reduced amygdala activity, and (c) increased activity in brain regions implicated in attentional deployment. MBSR training in patients with SAD may reduce emotional reactivity while enhancing emotion regulation. These changes might facilitate reduction in SAD-related avoidance behaviors, clinical symptoms, and automatic emotional reactivity to negative self-beliefs in adults with SAD.

The neural bases of emotion regulation: reappraisal and suppression of negative emotion.

BACKGROUND: Emotion regulation strategies are thought to differ in when and how they influence the emotion-generative process. However, no study to date has directly probed the neural bases of two contrasting (e.g., cognitive versus behavioral) emotion regulation strategies. This study used functional magnetic resonance imaging (fMRI) to examine cognitive reappraisal (a cognitive strategy thought to have its impact early in the emotion-generative process) and expressive suppression (a behavioral strategy thought to have its impact later in the emotion-generative process). METHODS: Seventeen women viewed 15 sec neutral and negative emotion-eliciting films under four conditions--watch-neutral, watch-negative, reappraise-negative, and suppress-negative--while providing emotion experience ratings and having their facial expressions videotaped. RESULTS: Reappraisal resulted in early (0-4.5 sec) prefrontal cortex (PFC) responses, decreased negative emotion experience, and decreased amygdala and insular responses. Suppression produced late (10.5-15 sec) PFC responses, decreased negative emotion behavior and experience, but increased amygdala and insular responses. CONCLUSIONS: These findings demonstrate the differential efficacy of reappraisal and suppression on emotional experience, facial behavior, and neural response and highlight intriguing differences in the temporal dynamics of these two emotion regulation strategies.
