The relationships among working alliance, group cohesion and homework engagement in group cognitive behaviour therapy for social anxiety disorder.

OBJECTIVE: Few studies have investigated the role of generic relational factors, such as group cohesion and working alliance, in group cognitive behaviour therapy (CBT) for social anxiety disorder (SAD). The aim of this study was to examine the temporal associations among working alliance, group cohesion, and an index of a CBT-specific factor, homework engagement, as correlates of fear of negative evaluation and symptoms of social anxiety in group CBT for SAD. METHOD: There were 105 participants with a diagnosis of social anxiety disorder who were randomly assigned to 12 sessions of group imagery-enhanced or standard CBT. Participants completed measures at various time points during the 12-session interventions, and the relationship among variables was examined through random-intercept cross-lagged panel models. RESULTS: Group cohesion was significantly associated with social anxiety symptoms at the end of treatment, however there was no significant relationship with working alliance. Greater homework engagement predicted lower social interaction anxiety, but only during mid-treatment. CONCLUSION: The results highlight the importance of supporting group cohesion and maximising homework engagement during core components of social anxiety treatment such as behavioural experiments.

Concurrent and prospective associations between negative social-evaluative beliefs, safety behaviours, and symptoms during and following cognitive behavioural group therapy for social anxiety disorder.

BACKGROUND: Improving the delivery of cognitive-behavioural therapy (CBT) for social anxiety disorder (SAD) requires an in-depth understanding of which cognitive and behavioural mechanisms drive change in social anxiety symptoms (i.e., social interaction anxiety) during and after treatment. The current study explores the dynamic temporal associations between theory-driven cognitive and behavioural mechanisms of symptom change both during and following group CBT. METHODS: A randomized controlled trial of imagery-enhanced CBT (n = 51) versus traditional verbal CBT (n = 54) for social anxiety was completed in a community mental health clinic setting. This study included data collected from 12-weekly sessions and a 1-month follow-up session. Mixed models were used to assess magnitude of change over the course of treatment. Cross-lagged panel models were fit to the data to examine temporal relationships between mechanisms (social-evaluative beliefs, safety behaviours) and social interaction anxiety symptoms. RESULTS: Participants in both CBT groups experienced significant improvements across all cognitive, behavioural, and symptom measures, with no significant differences in the magnitude of changes between treatments. During treatment, greater social-evaluative beliefs (fear of negative evaluation, negative self-portrayals) at one time point (T) were predictive of more severe SAD symptoms and safety behaviours at T+1. Social-evaluative beliefs (fear of negative evaluation, probability and cost of social failure) and safety behaviours measured at post-treatment were positively associated with SAD symptoms at the 1-month follow-up. CONCLUSIONS: The current study identifies social-evaluative beliefs that may be important targets for symptom and avoidance reduction during and following CBT. Assessment of these social-evaluative beliefs throughout treatment may be useful for predicting future SAD symptoms and avoidance, and for adapting treatment to promote optimal change for patients.

Resting state connectivity predictors of symptom change during gaze-contingent music reward therapy of social anxiety disorder.

BACKGROUND: Social anxiety disorder (SAD) is common, first-line treatments are often only partially effective, and reliable predictors of treatment response are lacking. Here, we assessed resting state functional connectivity (rsFC) at pre-treatment and during early treatment as a potential predictor of response to a novel attention bias modification procedure, gaze-contingent music reward therapy (GC-MRT). METHODS: Thirty-two adults with SAD were treated with GC-MRT. rsFC was assessed with multi-voxel pattern analysis of fMRI at pre-treatment and after 2-3 weeks. For comparison, 20 healthy control (HC) participants without treatment were assessed twice for rsFC over the same time period. All SAD participants underwent clinical evaluation at pre-treatment, early-treatment (week 2-3), and post-treatment. RESULTS: SAD and depressive symptoms improved significantly from pre-treatment to post-treatment. After 2-3 weeks of treatment, decreased connectivity between the executive control network (ECN) and salience network (SN), and increased connectivity within the ECN predicted improvement in SAD and depressive symptoms at week 8. Increased connectivity between the ECN and default mode network (DMN) predicted greater improvement in SAD but not depressive symptoms at week 8. Connectivity within the DMN decreased significantly after 2-3 weeks of treatment in the SAD group, while no changes were found in HC over the same time interval. CONCLUSION: We identified early changes in rsFC during a course of GC-MRT for SAD that predicted symptom change. Connectivity changes within the ECN, ECN-DMN, and ECN-SN may be related to mechanisms underlying the clinical effects of GC-MRT and warrant further study in controlled trials.

The Use of Dynamic Cognitive Behavioural Therapy (DCBT) in Social Anxiety Disorder (SAD): A Theoretical Integration Initiative.

Psychotherapy theorists can often become fervent advocates of the schools they follow and place the doctrines of the theories they adopt above all else. This situation can sometimes turn into a war of theories between researchers as well. However, therapists should not aim to shape therapy sessions according to their methods but to use them in line with clients' needs. Although it is emphasised that the integration of both psychoanalytic and cognitive behavioural therapy techniques, which is going to be named dynamic cognitive behavioural therapy (DCBT) in this case report, will provide more effective and permanent treatment, a discernible gap exists regarding the integration of these theories and their use in psychotherapy. Taking into account this gap, it is considered important to use this approach with a client who has a social anxiety disorder (SAD). Therefore, this study aims to describe the almost forgotten DCBT approach step by step through a case report and reveal the effectiveness of this approach. As a result, DCBT seems to be effective in the treatment of SAD.

An Investigation of Cognitive and Affective Changes During Group Imagery Rescripting for Social Anxiety Disorder.

Recurrent, negative self-imagery is common in social anxiety disorder (SAD). Imagery rescripting (ImRs) is an effective therapeutic technique that aims to target past aversive memories to modify their associated meanings, and update the encapsulated negative schematic beliefs. The current study aimed to extend previous research by investigating the cognitive and affective shifts during each phase of ImRs delivered within a group cognitive behavioral therapy protocol. Participants (N = 32) retrieved an aversive memory associated with social anxiety and were guided through brief cognitive restructuring, prior to completing ImRs. Core beliefs associated with the memory (strength and valence) and fear of negative evaluation were assessed before and after ImRs and affect was assessed following each phase. Strength and affective valence of encapsulated core beliefs about the self, others, the world, and the image itself significantly reduced following ImRs, and core beliefs were updated to become more positive. Participants reported large affective shifts early in the process, with smaller shifts in the later stages. Fear of negative evaluation did not significantly reduce following ImRs. Outcomes provide some support for cognitive and affective changes during group ImRs for SAD and suggest future research directions to investigate longer-term impacts and to better understand the underlying mechanisms of the technique.

Impacts of imagery-enhanced versus verbally-based cognitive behavioral group therapy on psychophysiological parameters in social anxiety disorder: Results from a randomized-controlled trial.

Social anxiety disorder (SAD) is associated with marked physiological reactivity in social-evaluative situations. However, objective measurement of biomarkers is rarely evaluated in treatment trials, despite potential utility in clarifying disorder-specific physiological correlates. This randomized controlled trial sought to examine the differential impact of imagery-enhanced vs. verbal-based cognitive behavioral group therapy (IE-CBGT, n = 53; VB-CBGT, n = 54) on biomarkers of emotion regulation and arousal during social stress in people with SAD (pre- and post-treatment differences in heart rate variability (HRV) and skin conductance). We acquired psychophysiological data from randomized participants across four social stress test phases (baseline, speech preparation, speech, interaction) at pre-treatment, and 1- and 6-months post-treatment. Analyses revealed that IE-CBGT selectively attenuated heart rate as indexed by increases in median heart rate interval (median-RR) compared to VB-CBGT at post-treatment, whereas one HRV index showed a larger increase in the VB-CBGT condition before but not after controlling for median-RR. Other psychophysiological indices did not differ between conditions. Lower sympathetic arousal in the IE-CBGT condition may have obviated the need for parasympathetic downregulation, whereas the opposite was true for VB-CBGT. These findings provide preliminary insights into the impact of imagery-enhanced and verbally-based psychotherapy for SAD on emotion regulation biomarkers.

Don't be afraid, try to meditate- potential effects on neural activity and connectivity of psilocybin-assisted mindfulness-based intervention for social anxiety disorder: A systematic review.

BACKGROUND: Current first-line treatment for social anxiety disorder (SAD), one of the most prevalent anxiety disorders, is limited in its efficacy. Hence, novel treatment approaches are urgently needed. The current review suggests a combination of meditation-based interventions and the administration of a psychedelic as a future alternative treatment approach. While both separate treatments show promise in the treatment of (other) clinical conditions, their combination has not yet been investigated in the treatment of psychopathologies. AIM: With a systematic literature review, we aim to identify the potential mechanisms by which combined psilocybin and mindfulness treatment could adjust anomalous neural activity underlying SAD and exert therapeutic effects. RESULTS: Thirty experimental studies investigating the neural effects of meditation or psilocybin treatment in healthy and patient samples were included. Findings suggest that psilocybin-assisted meditation interventions might change cognitive processes like biased attention to threat linked to SAD by modulating connectivity of the salience network, balancing the activity and connectivity of cortical-midline structures, and increasing frontoparietal control over amygdala reactivity. CONCLUSIONS: Future studies should investigate whether psilocybin-assisted mindfulness-based intervention can provide therapeutic benefits to SAD patients who are do not remit following conventional therapy.

Imagery-enhanced v. verbally-based group cognitive behavior therapy for social anxiety disorder: a randomized clinical trial.

BACKGROUND: Cognitive behavior therapy (CBT) is effective for most patients with a social anxiety disorder (SAD) but a substantial proportion fails to remit. Experimental and clinical research suggests that enhancing CBT using imagery-based techniques could improve outcomes. It was hypothesized that imagery-enhanced CBT (IE-CBT) would be superior to verbally-based CBT (VB-CBT) on pre-registered outcomes. METHODS: A randomized controlled trial of IE-CBT v. VB-CBT for social anxiety was completed in a community mental health clinic setting. Participants were randomized to IE (n = 53) or VB (n = 54) CBT, with 1-month (primary end point) and 6-month follow-up assessments. Participants completed 12, 2-hour, weekly sessions of IE-CBT or VB-CBT plus 1-month follow-up. RESULTS: Intention to treat analyses showed very large within-treatment effect sizes on the social interaction anxiety at all time points (ds = 2.09-2.62), with no between-treatment differences on this outcome or clinician-rated severity [1-month OR = 1.45 (0.45, 4.62), p = 0.53; 6-month OR = 1.31 (0.42, 4.08), p = 0.65], SAD remission (1-month: IE = 61.04%, VB = 55.09%, p = 0.59); 6-month: IE = 58.73%, VB = 61.89%, p = 0.77), or secondary outcomes. Three adverse events were noted (substance abuse, n = 1 in IE-CBT; temporary increase in suicide risk, n = 1 in each condition, with one being withdrawn at 1-month follow-up). CONCLUSIONS: Group IE-CBT and VB-CBT were safe and there were no significant differences in outcomes. Both treatments were associated with very large within-group effect sizes and the majority of patients remitted following treatment.

Does treatment preference affect outcome in a randomized trial of a mindfulness intervention versus cognitive behaviour therapy for social anxiety disorder?

Research suggests that treatment preference may affect outcome of randomized clinical trials, but few studies have assessed treatment preference in trials comparing different types of psychosocial interventions. This study used secondary data analysis to evaluate the impact of treatment preference in a randomized trial of a mindfulness-based intervention adapted for social anxiety disorder (MBI-SAD) versus cognitive behaviour group therapy (CBGT). Ninety-seven participants who met DSM-5 criteria for SAD were randomized. Prior to randomization, twice as many participants expressed a preference for the MBI-SAD over CBGT. However, being allocated or not to one's preferred treatment had no impact on treatment response. Additionally, with the exception of perception of treatment credibility, treatment matching had no impact on treatment-related variables, including treatment initiation, session attendance, homework compliance, satisfaction with treatment and perception that treatment met expectations. In sum, despite the greater preference for the mindfulness intervention in this sample of participants with SAD, we found little evidence of preference effects on our study outcomes. Findings should be viewed as preliminary and require replication.

Neurophysiological predictors of gaze-contingent music reward therapy among adults with social anxiety disorder.

Social anxiety disorder (SAD) is associated with fear of negative evaluation and heightened performance monitoring. The best-established treatments help only a subset of patients, and there are no well-established predictors of treatment response. The current study investigated whether individual differences in processing errors might predict response to gaze-contingent music reward therapy (GC-MRT). At baseline, healthy control subjects (HC; n = 20) and adults with SAD (n = 29), ages 19-43 years, completed the Flanker Task while electroencephalography (EEG) data were recorded. SAD participants then received up to 12 sessions over 8 weeks of GC-MRT, designed to train participants' attention away from threatening and toward neutral faces. Clinical assessments were completed 9- (post-treatment) and 20-weeks (follow-up) after initiating the treatment. At baseline, compared to HC, SAD performed the task more accurately and exhibited increased error-related negativity (ERN) and delta power to error commission. After controlling for age and baseline symptoms, more negative ERN and increased frontal midline theta (FMT) predicted reduced self-reported social anxiety symptoms at post-treatment, and FMT also predicted clinician-rated and self-reported symptom reduction at the follow-up assessment. Hypervigilance to error is characteristic of SAD and warrants further research as a predictor of treatment response for GC-MRT.

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.

Mindfulness-based interventions for social anxiety disorder: A systematic review and meta-analysis.

Various psychiatric disorders are treated with mindfulness-based interventions (MBIs), although the efficacy of MBIs in patients with social anxiety disorder (SAD) is unclear. In this meta-analysis, we investigated the efficacy of MBIs on SAD symptoms. Systematic searches were performed in various databases, and 11 eligible randomized controlled trials (RCTs) and 5 single-arm trials were identified. The between-groups analysis of the 11 RCTs showed that Hedges' g = 0.00, while the within-group analysis showed a large pre-post effect size (g = 1.20).MBIs were superior to the no-treatment comparator (g = 0.89), equivalent to specific active treatment (g = -0.19), and less effective than evidence-based treatment (i.e., cognitive behavioral therapies) (g = -0.29).MBIs significantly alleviated depressive symptoms and improved mindfulness, quality of life, and self-compassion. Meta-regression analysis showed a dose-response relationship between the alleviation of SAD symptoms and the duration of the MBIs (ß = 0.659). Follow-up analysis showed that the effects of MBIs on SAD persisted for 12 months (g = 0.231). An analysis of the 5 single-arm trials found that MBIs had a medium effect in alleviating SAD symptoms (g = 0.48). Future research is needed regarding the design of large RCTs of MBIs on SAD patients.

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.

Randomized trial of cognitive behaviour group therapy and a mindfulness-based intervention for social anxiety disorder: Preliminary findings.

Recent studies have evaluated the possible efficacy of mindfulness-based interventions (MBIs) for social anxiety disorder (SAD). However, few trials have compared MBIs with a first-line treatment. This study evaluated the relative efficacy of an MBI adapted for SAD (MBI-SAD) to cognitive behaviour group therapy (CBGT) for SAD. Participants were randomized to 12 weekly group sessions of the MBI-SAD (n = 52) or CBGT (n = 45). Results revealed that CBGT fared better than the MBI-SAD in reducing clinician- and self-rated social anxiety severity. The difference between the MBI-SAD and CBGT exceeded the prespecified noninferiority margin for our primary outcome the Liebowitz Social Anxiety Scale, but findings are inconclusive as the width of the confidence interval extended in both directions surrounding the noninferiority margin. The MBI-SAD compared favourably with CBGT in improving other indices of well-being (depression, self-esteem, satisfaction with life, social adjustment). Contrary to expectation, the MBI-SAD did not produce greater changes in mindfulness and self-compassion than CBGT. Overall, results confirm that CBGT is robust treatment for SAD and should be considered as first-line treatment.

Training the anxious brain: using fMRI-based neurofeedback to change brain activity in adolescence.

Anxiety disorders are a leading cause of morbidity and entail a lot of costs. Adolescence is characterized by social fears and poor emotion regulation abilities which together increase the likelihood of the emergence of anxiety disorders. This emotion dysregulation is potentially caused by the emotion regulating brain areas, such as the prefrontal cortex and temporal cortex, that are still undergoing developmental changes throughout late adolescence. Recently, new approaches have used functional magnetic resonance imaging-based neurofeedback to help participants gain control over emotion regulation brain networks by receiving real-time feedback on their brain activity and to use effective emotion regulation abilities. In this review, we provide an overview of the developmental changes in the brain and the corresponding behavioural changes, and explore how these can be influenced during adolescence using neurofeedback. We conclude that recent studies show promising results that children and adolescents can self-regulate emotion regulation brain networks thereby supporting the development of effective emotion regulation abilities. WHAT THIS PAPER ADDS: Functional magnetic resonance imaging-based neurofeedback can be used for brain self-regulation in development. The emotion regulation networks play a key role in treating social anxiety with neurofeedback.

Interpretation Bias Modification Versus Progressive Muscle Relaxation for Social Anxiety Disorder: A Web-Based Controlled Trial.

Computerized interpretation bias modification (IBM) programs show promise for the treatment of anxiety disorders, though they have rarely been compared to active treatments. The goal of the present study was to compare the efficacy of IBM to progressive muscle relaxation (PMR) for the treatment of social anxiety disorder (SAD). Sixty-four participants with SAD were recruited from across the United States and randomly assigned to 8 internet-delivered twice-weekly sessions of IBM or PMR. Participants were administered assessments of primary symptom outcomes and interpersonal suicide risk factors at posttreatment and 3-month follow-up. IBM led to significantly lower negative interpretation bias than PMR at posttreatment but not follow-up. Both conditions experienced comparable reductions in social anxiety from pretreatment to follow-up (IBM d = 1.37, PMR d = 1.28). They also experienced significant reductions in depression and general anxiety that did not differ from one another. Additionally, IBM led to greater reductions in thwarted belongingness than PMR at posttreatment but not follow-up. Overall, these findings suggest IBM is not more effective than PMR for reducing social anxiety, though there was some evidence of its superiority in decreasing suicide risk. Limitations and directions for future research are discussed.

Effectiveness of mindfulness-based cognitive therapy in patients with anxiety disorders in secondary-care settings: A randomized controlled trial.

AIM: The primary objective of this study was to examine the effectiveness of mindfulness-based cognitive therapy (MBCT) in secondary-care settings where the vast majority of the patients have already undergone pharmacotherapy but have not remitted. METHODS: Eligible participants were aged between 20 and 75 years and met the criteria for panic disorder/agoraphobia or social anxiety disorder specified in the DSM-IV. They were randomly assigned to either the MBCT group (n = 20) or the wait-list control group (n = 20). The primary outcome was the difference in mean change scores between pre- and post-intervention assessments on the State-Trait Anxiety Inventory (STAI). The outcome was analyzed using an intent-to-treat approach and a mixed-effect model repeated measurement. RESULTS: We observed significant differences in mean change scores for the STAI State Anxiety subscale (difference, -10.1; 95% confidence interval, -16.9 to -3.2; P < 0.005) and STAI Trait Anxiety subscale (difference, -11.7; 95% confidence interval, -17.0 to -6.4; P < 0.001) between the MBCT and control groups. CONCLUSION: MBCT is effective in patients with anxiety disorders in secondary-care settings where the vast majority of patients are treatment-resistant to pharmacotherapy.

Predictors of outcome in guided self-help cognitive behavioural therapy for common mental disorders in primary care.

Cognitive behavioural therapy (CBT) can effectively treat common mental disorders (CMDs), but access to treatment is insufficient. Guided self-help (GSH) CBT has shown effects comparable to face-to-face CBT and may be a resource-efficient treatment alternative. However, not all patients respond to GSH. Learning more about predictors of outcome may increase knowledge regarding which patients respond to GSH. The aim of this study was to investigate predictors of outcome for GSH CBT for patients with CMDs in primary care. Consecutive patients (N = 396) with a principal disorder of depression, anxiety, insomnia or stress-related disorders were included. All patients received GSH CBT. Outcomes were remission status, reliable change and post-treatment depression ratings. Predictors investigated were clinical, demographic and therapy-related variables. Analyses were conducted using logistic and linear regression. Higher educational level predicted remission, higher quality of life ratings predicted remission and decreased depression, and higher age at onset predicted reliable change. Therapy-related variables, i.e. patient adherence to treatment and patients' and clinicians' estimation of treatment response, were all related to outcome. More large-scale studies are needed, but the present study points at the importance of therapy-related variables such as monitoring and supporting treatment adherence for an increased chance of remission.
