Mindfulness and acceptance-based group therapy versus traditional cognitive behavioral group therapy for social anxiety disorder: A randomized controlled trial
ABSTRACT Recent research has supported the use of mindfulness and acceptance-based interventions for Social Anxiety Disorder (SAD).
The purpose of the present study was to compare mindfulness and acceptance-based group therapy (MAGT) with cognitive behavioral group therapy (CBGT) with respect to outcome. It was hypothesized that MAGT and CBGT would both be superior to a control group but not significantly different from one another.
Individuals (N = 137, mean age = 34 years, 54% female, 62% White, 20% Asian) diagnosed with SAD were randomly assigned to MAGT (n = 53), CBGT (n = 53) or a waitlist control group (n = 31). The primary outcome was social anxiety symptom severity assessed at baseline, treatment midpoint, treatment completion, and 3-month follow-up. Secondary outcomes were cognitive reappraisal, mindfulness, acceptance, and rumination. Depression, valued living, and group cohesion were also assessed.
As hypothesized, MAGT and CBGT were both more effective than the control group but not significantly different from one another on social anxiety reduction and most other variables assessed.
The present research provides additional support for the use of mindfulness and acceptance-based treatments for SAD, and future research should examine the processes by which these treatments lead to change.

ABSTRACT: Postevent processing (PEP; reviewing a past social event in detail) is a key maintenance factor of social anxiety disorder (SAD). The current study examined the efficacy of a single session cognitive restructuring or mindfulness strategy on decreasing PEP and its associated effects, and investigated the cognitive processes involved. Fifty-six individuals with SAD completed a speech task to elicit PEP and were taught a cognitive restructuring, mindfulness, or control strategy to manage their negative thoughts. Participants in the cognitive restructuring and mindfulness conditions reported significantly reduced PEP and improved affect as compared to the control condition. There were no significant differences between the cognitive restructuring and mindfulness conditions. Participants in the cognitive restructuring condition reported decreased probability and cost biases. Regardless of study condition, decreases in cost biases and maladaptive beliefs significantly predicted reductions in PEP. Cognitive restructuring and mindfulness appear to be promising strategies to decrease PEP and improve affect.Journal of Anxiety Disorders 06/2014; 28:570-579.

ABSTRACT: Mindfulness-based interventions for depression and anxiety emphasize the importance of observing present moment experience, but observing has often been positively related to anxiety and unrelated to depression symptoms. The current study sought to better understand the conditions and mechanism through which observing relates to symptoms by examining six conditional process models in which (1) nonreactivity moderates the direct effect of observing on symptoms of anxiety and depression symptoms and (2) nonreactivity moderates the indirect effect of observing on anxiety and depression via cognitive emotion regulation strategies (i.e. rumination, worry, and reappraisal).Journal of Affective Disorders 08/2014; 165:31-7.

ABSTRACT: Acceptance and commitment therapy (ACT) has attracted a lot of interest during the last 10-15 years with a strong increase of the number of randomized controlled trials (RCTs). The present review and meta-analysis includes 60 RCTs (4,234 participants) on psychiatric disorders, somatic disorders, and stress at work. The mean effect size across all comparisons was small (0.42). Compared to the Öst (2008) meta-analysis there was no significant improvement in methodological quality and deterioration in effect size (from 0.68). When ACT was compared to various forms of cognitive or behavioral treatments a small and non-significant effect size of 0.16 was obtained. An evidence-base evaluation showed that ACT is not yet well-established for any disorder. It is probably efficacious for chronic pain and tinnitus, possibly efficacious for depression, psychotic symptoms, OCD, mixed anxiety, drug abuse, and stress at work, and experimental for the remaining disorders.Behaviour Research and Therapy 10/2014; 61.
