Attention and interpretation bias modification treatment for social anxiety disorder: A randomized clinical trial of efficacy and synergy

The role of interpretation biases and safety behaviours in social anxiety: an intensive longitudinal study

BACKGROUND

Interpretation bias and safety behaviours (Safe-B) have been proposed as factors perpetuating social anxiety (SA). However, longitudinal research on how they contribute to SA in everyday life is scarce.

AIM

The aim was to examine whether interpretation bias predicts daily Safe-B and SA. A mediated moderation was hypothesized, where the relationship between daily social stressors and Safe-B would be moderated by interpretation bias, and Safe-B, in turn, would mediate the association between stressors and SA levels. In addition, it was hypothesized that prior levels of SA would predict higher Safe-B use, especially in co-occurrence with stressors.

METHOD

An intensive longitudinal design was employed, with 138 vocational training students (51% men, mean age 20.15 years). They completed initial measures of SA and interpretation bias and 7-day diaries with measures of social stressors, Safe-B, and SA. They reported SA levels two months later.

RESULTS

Both stressors and interpretation bias in ambiguous situations predicted Safe-B, which in turn predicted daily SA levels. However, neither interpretation bias nor Safe-B predicted SA levels at the follow-up, and interpretation bias did not moderate the association between stressors and daily SA. In addition, the relationship between stressors and Safe-B was stronger in people with higher initial SA levels.

CONCLUSIONS

The results suggest that Safe-B are a mechanism through which earlier SA levels and interpretation bias contribute to higher SA levels in daily life.

Social Interpretation Inflexibility and Functioning: Associations with Symptoms and Stress

Introduction: Interpretation inflexibility has been implicated in a range of mental health problems, including depression, social anxiety, and paranoia. Inflexible interpretation of social situations may be particularly important as it can set the stage for problems in social functioning, a symptom cutting across all three groups of disorders. Methods: This study aimed to examine the interrelations among interpretation inflexibility, social functioning impairment, and affective and psychotic symptoms. The study also explored the potential moderating effects of COVID-related preoccupation, as an example of a major stressor, on these relationships. Results: Based on a sample recruited from the general population (N = 247), interpretation inflexibility was found to be associated with social functioning impairment, with affective symptoms and paranoia as statistical mediators of the association. These relationships were magnified by ambient stress during the COVID-19 pandemic—a moderated mediation that was found only in relation to affective symptoms but not paranoia. A parallel network analysis further confirmed the moderating effects of COVID-related preoccupation on the relation between interpretation inflexibility and depression. Limitations: Measuring ambient stress with a self-report question on COVID-related preoccupation may not be representative of the amount of distress an individual experienced during the pandemic. Also, our mediation models were performed on cross-sectional data, thus not necessarily implying a feed-forward causal mediational relationship. Conclusions: These findings highlight the importance of examining social functioning as a crucial outcome, as well as the differential role of stress in modulating social interpretation flexibility with respect to affective vs. psychotic symptoms.

Scary in the eye of the beholder: Attentional bias and attentional retraining for social anxiety

Consistent with cognitive models of social anxiety, socially anxious individuals show cognitive biases that magnify their perceived level of threat in the environment.

OBJECTIVES

The first objective was to determine whether attentional bias for socially threatening stimuli occurs after concomitant depression has been controlled. The second objective was to test the effectiveness of the Attention Control Training Program for Social Anxiety (ACTP-SA) for reducing social anxiety attentional bias and improving therapeutic indices in people with social anxiety.

METHOD

In the first study, socially anxious (N = 30) and non-anxious individuals (N = 30) completed the Beck Depression Inventory-II, Spielberger's State-Trait Anxiety Inventory, Conner's Social Phobia Inventory, a social-anxiety Stroop test, and a clinical interview. In the second study, individuals with social anxiety (N = 30) were randomly assigned to an experimental group that received 4 sessions of ACTP-SA, or to a sham-intervention control condition. At the post-test and a 3-month follow-up, both groups completed the same measures as in Study 1.

RESULTS

In Study 1, socially anxious individuals showed higher attentional bias for threatening stimuli than the controls, after depression had been controlled for. In Study 2, participants in the experimental group, compared with the controls, showed greater reductions in attentional bias, social anxiety, and trait anxiety at post-test and follow-up.

CONCLUSIONS

The results underscore the importance of information processing biases in social anxiety and the benefits of attentional bias training as a complementary intervention for modifying symptoms of social anxiety.

Attention and interpretation cognitive bias change: A systematic review and meta-analysis of bias modification paradigms

This systematic review and meta-analysis examines the effect of Cognitive Bias Modification for attention (CBM-A) and interpretation (CBM-I) on reducing the targeted biases and investigates moderators of each approach. PsycINFO, PsychArticles, and PubMED databases were searched for randomized-controlled studies published before March 2020 with pre- and post-CBM cognitive bias outcome measures, resulting in 91 CBM-A (n = 5914 individuals) and 70 CBM-I samples (n = 4802 individuals). Random-effects models and Hedge's g calculation showed significant medium overall effects of bias reduction with moderate to high heterogeneity (CBM-A g = 0.49 [0.36, 0.64], I² = 85.19%; CBM-I g = 0.58 [0.48, 0.68], I² = 70.92%). Effect sizes did not differ between approaches and remained significant after trim-and-fill adjustment for possible publication bias. Moderator variables were investigated with meta-regression and subgroup analyses. Participant age, symptom type, control condition and number of trials moderated CBM-A; student and clinical status moderated CBM-I effect size. Results support attention and interpretation modification in controlled laboratory and variable (online) training settings for non-clinical and clinical samples across various symptom types (anxiety, depression, substance use, eating disorders). Further empirical evidence is necessary to determine optimal sample and methodological combinations most strongly associated with adaptive behavioral outcomes.

The effect of immersive virtual reality-based attentional bias modification on anxiety mitigation in healthy population

The present study compared an immersive virtual reality-based attentional bias modification (immersive VR-ABM) with the desktop version of the VR-ABM and an immersive virtual reality-based game (immersive VR-game) to examine the possible effect of the immersive presence on self-reported emotional reactions to a stressful task. One hundred and twenty participants were randomly assigned into three groups, and each group received a three-turn induction-intervention training. Anxiety symptoms were assessed at pre-induction, post-induction, and post-training. Results showed that virtual reality-based anxiety was induced and alleviated successfully in all three groups, but only the immersive VR-ABM group showed an accumulated effect on self-reported anxiety across sessions. The attentional bias based on probe latencies indicated no significant change in either the immersive or desktop VR-ABM groups. The present findings support the hypothesized VR-ABM's effect on self-reported anxiety at the immersive presence. The practical implications of using immersive VR-ABM are discussed for obtaining ecological validity.

The Relationship Between Attention, Interpretation, and Memory Bias During Facial Perception in Social Anxiety

Although cognitive theories suggest the interactive nature of information processing biases in contributing to social anxiety, most studies to date have investigated these biases in isolation. This study aimed at (a) testing the association between social anxiety and each of the threat-related cognitive biases: attention, interpretation, and memory bias; and (b) examining the relationship between these cognitive biases in facial perception. We recruited an unselected sample of 188 adult participants and measured their level of social anxiety and cognitive biases using faces displaying angry, disgusted, happy, and ambiguous versions of these expressions. All bias tasks were assessed with the same set of facial stimuli. Regression analyses showed that social anxiety symptoms significantly predicted attention avoidance and poorer sensitivity in recognizing threatening faces. Social anxiety was, however, unrelated to interpretation bias in our sample. Results of path analysis suggested that attention bias influenced memory bias indirectly through interpretation bias for angry but not disgusted faces. Our findings suggest that, regardless of social anxiety level, when individuals selectively oriented to faces displaying anger, the faces were interpreted to be more negative. This, in turn, predicted better memory for the angry faces. The results provided further empirical support for the combined cognitive bias hypothesis.

The combined cognitive bias hypothesis in anxiety: A systematic review and meta-analysis

Cognitive theories have postulated the relational nature of different cognitive biases in the development and maintenance of anxiety disorders. To test this combined cognitive bias hypothesis, this review addressed the following questions: (i) whether different cognitive biases are associated with each other and (ii) whether one bias influences another bias. We identified 36 articles that studied the relationship between cognitive biases (attention, interpretation and memory bias). Of these, 31 studies were entered into two meta-analyses. Sixteen studies were included in the first meta-analysis of the correlation between cognitive bias indices. A further 15 studies were included in another meta-analysis to examine the transfer effects of cognitive bias modification (CBM) to another bias. Both meta-analyses yielded small but significant overall pooled effect sizes after the removal of outliers (r = 0.11 and g = 0.19 respectively). Moderator analyses revealed that the relationship between interpretation and memory bias was significantly stronger than other types of cognitive bias correlations and CBM is more potent in modifying biases when it was delivered in the laboratory compared with online. Our review quantifies the strength of the relationships between biases and transfer effects following CBM, which serves as a basis to further understand the mechanisms underlying biased information processing.

Does attention bias modification reduce anxiety in socially anxious college students? An experimental study of potential moderators and considerations for implementation

According to cognitive models, preferential attention to social threat contributes to maintenance of social anxiety. Socially anxious individuals are known to show attention biases to threatening stimuli, although there is inconsistency in the literature with regards to the type of attentional biases they present. This study examines the effect of attention bias modification (ABM) for social anxiety in non-treatment-seeking college students meeting social anxiety disorder criteria, taking into consideration previous mixed results regarding its effectiveness. Attention bias levels and types (i.e. vigilance vs avoidance) at baseline were examined and considered as potential moderators of ABM effects. Sixty-eight socially anxious individuals were randomly allocated to ABM vs placebo groups. A structured interview and self-report assessment were completed at pre-treatment and post-treatment. Results showed half of the participants presented few attention biases at baseline, and the rest presented either vigilance or avoidance. Participants with low attention biases scored higher in social anxiety than those showing avoidance and there was no difference between those showing vigilance vs avoidance. No significant effects from pre to post treatment were observed in attention biases, self-report or structured interview of anxiety in the ABM group. Baseline attention biases did not moderate these effects. Results are discussed with regards to implications for future research towards the creation of more effective protocols, based on the needs of heterogeneous social anxiety sub-groups.

Development of a cognitive bias modification intervention for anxiety disorders in primary care

OBJECTIVES

There is a great need for low-intensity, scalable treatments in primary care, where most anxious patients first present for treatment. We describe Stage IA treatment development and a Stage IB feasibility trial of cognitive bias modification (CBM) for transdiagnostic anxiety in primary care.

METHODS

The online intervention, Mental Habits, comprised eight sessions of a personalized CBM targeting attention and interpretation biases. Coaches assisted patients in using the website, monitored progress via a dashboard, and shared information with primary care providers. We evaluated Mental Habits in an open trial (N = 14) and a randomized controlled trial (RCT) (N = 40) in primary care patients with anxiety disorders.

RESULTS

We compared results to a priori benchmarks of clinically meaningful outcomes. In the open trial, Mental Habits met feasibility, acceptability, and efficacy benchmarks. In the pilot RCT, there was greater dropout at one study site which ultimately closed. In the intent-to-treat analyses, Mental Habits met the benchmark for self-report, but not the interview measure of anxiety. Symptom Tracking did not meet the benchmark for self-report or interview measures of anxiety. In per-protocol analyses, Mental Habits exceeded the benchmark for both self-report and interview measures, whereas Symptom Tracking met the benchmark for self-report. Interpretation bias improved in the Mental Habits group, but not in Symptom Tracking. No effects were observed for attention bias.

CONCLUSION

The online CBM intervention demonstrated good acceptability and, when delivered at a stable primary care clinic, preliminary effectiveness in primary care. A larger RCT is warranted to test effectiveness.

PRACTITIONER POINTS

A personalized, transdiagnostic Cognitive Bias Modification (CBM) intervention for anxiety in primary care is acceptable to primary care patients with social anxiety disorder, generalized anxiety disorder, and/or panic disorder /agoraphobia. With training and supervision from licensed mental health clinicians, bachelor's-level coaches can assist primary care patients to self-administer CBM. Offering a low-intensity, self-directed anxiety intervention in primary care can greatly expand the reach of anxiety treatment, with minimal need for additional resources. Interpretation bias may be an important clinical target for primary care patients with anxiety.

A Single-Session Combined Cognitive Bias Modification Training Targeting Attention and Interpretation Biases in Aggression

Experimental studies applying cognitive bias modification of attention (CBM-A) and interpretation (CBM-I) to reduce aggression have examined the effect of modifying each cognitive bias in isolation. In order to maximise the potential impact on both biases and symptom reduction, we examined whether a combined bias training procedure targeting both attention and interpretation biases (CBM-AI) in combination would be more effective than targeting interpretation bias (CBM-I) alone. University students (17–35 years) were randomly assigned to either a single session of CBM-AI training (n = 40), CBM-I training (n = 40), or a control condition (n = 40). Contrary to our expectations, participants showed an increase in adaptive attention and pro-social interpretation bias in all training conditions. Additionally, in none of the conditions, we found a significant change on self-reported or behavioural aggression. These findings suggest: (1) that the combined training did not have added effect over single interpretation bias training, (2) that training interpretation bias may lead to changes in attention bias, (3) that elements of the control condition unexpectedly, but interestingly, also affected attention and interpretation biases, and (4) single-session CBM procedures do not produce robust effects on self-report or behavioural measures of aggression in unselected samples.

Efficacy of the Chinese version interpretation bias modification training in an unselected sample: A randomized trial

Training individuals to interpret ambiguous information in positive ways might be an effective method of reducing social anxiety. However, little research had been carried out in Chinese samples, and the effect of interpretation training on other processes such as attentional bias also remained unclear. This study examined the effect of interpretation bias modification program (IMP) on interpretation bias, social anxiety and attentional bias, and the possible mediation effects. 51 healthy adults were randomly assigned to either a 5-session IMP training that guided them to endorse benign interpretation in ambiguous scenarios or an interpretation control condition (ICC). Self-reported measures of social anxiety symptoms, attentional bias and interpretation bias were evaluated before and after training. Results showed that compared to control group, IMP group generated more positive interpretations and less negative interpretations after training (F(1,49) = 7.65, p<0.01, ηp2 = 0.14; F(1,49) = 14.60, p<0.01, ηp2 = 0.23respectively). IMP yielded greater interpretation bias reduction (F(1,49) = 12.84, p<0.01, ηp2 = 0.21) and social anxiety reduction (F(1,49) = 21.39, p<0.01, ηp2 = 0.30) than ICC, but change in attentional bias was not significant between IMP and the control group. Change in interpretation bias did not show a significant mediation effect in the relationship between training condition and social anxiety reduction. This study provided preliminary evidence for the efficacy of the Chinese version of IMP training. Possible methodological issues and interpretations underlying the findings were discussed. This study was registered in Chinese Clinical Trial Registry (www.chitr.org.cn), a WHO approved registry. The title of registration trial was "A Study on the efficiency of cognitive bias and attentional bias training on fear and phobia" and the registration number was ChiCTR2100045670.

Effect of internet-based attention bias modification on the anxiety of Japanese workers: A randomized controlled trial

Objectives

This study comprised a randomized controlled trial to examine the effect of internet‐based attention bias modification (iABM) on reducing workers' anxiety.

Methods

In total, 300 eligible participants were randomized according to sex and age; 180 were assigned to the intervention group and 120 to the control group. The word stimuli used in the iABM included eight positive words and eight neutral words. Participants were instructed to indicate the positive word's position as quickly and accurately as possible by tapping one of the two directions on display. The intervention included five sessions per participant over 1 month, resulting in a total of 600 trials. The main outcome measure was the total state anxiety score of the State‐Trait Anxiety Inventory (STAI).

Results

There was no significant difference in the net change in STAI scores between the intervention and control groups. The mean reaction time of the fifth session was significantly shorter than the mean reaction time of the first session. Furthermore, although there was no effect on the index of effect size Δ, the paired t‐test showed a significant decrease in the anxiety score.

Conclusions

The iABM intervention in this study did not enhance the amelioration of workers' anxiety when compared with the control condition.

Intrinsic functional connectivity in families genetically enriched for social anxiety disorder - an endophenotype study

BACKGROUND

Social anxiety disorder (SAD) is a serious psychiatric condition with a high prevalence, and a typical onset during childhood/adolescence. The condition runs in families, but it is largely unknown which neurobiological characteristics transfer this genetic vulnerability ('endophenotypes'). Using data from the Leiden Family Lab study on SAD, including two generations of families genetically enriched for SAD, we investigated whether social anxiety (SA) co-segregated with changes in intrinsic functional connectivity (iFC), and examined heritability.

METHODS

Functional MRI data were acquired during resting-state in 109 individuals (56 males; mean age: 31·5, range 9·2-61·5 years). FSL's tool MELODIC was used to perform independent component analysis. Six networks of interest (default mode, dorsal attention, executive control, frontoparietal, limbic and salience) were identified at the group-level and used to generate subject-specific spatial maps. Voxel-wise regression models, with SA-level as predictor and voxel-wise iFC as candidate endophenotypes, were performed to investigate the association with SA, within masks of the networks of interest. Subsequently, heritability was estimated.

FINDINGS

SA co-segregated with iFC within the dorsal attention network (positive association in left middle frontal gyrus and right postcentral gyrus) and frontoparietal network (positive association within left middle temporal gyrus) (cluster-forming-threshold z>2·3, cluster-corrected extent-threshold p<0·05). Furthermore, iFC of multiple voxels within these clusters was at least moderately heritable.

INTERPRETATION

These findings provide initial evidence for increased iFC as candidate endophenotype of SAD, particularly within networks involved in attention. These changes might underlie attentional biases commonly present in SAD.

Neural correlates of cognitive bias modification for interpretation

The effectiveness of cognitive bias modification for interpretation (CBM-I), a treatment method employed to reduce social anxiety (SA), has been examined. However, the neural correlates of CBM-I remain unclear, and we aimed to elucidate brain activities during intervention and activity changes associated with CBM-I effectiveness in a pre–post intervention comparison. Healthy participants divided into two groups (CBM, control) were scanned before, during and after intervention using functional magnetic resonance imaging. Ambiguous social situations followed by positive outcomes were repeatedly imagined by the CBM group during intervention, while half of the outcomes in the control group were negative. Whole-brain analysis revealed that activation of the somatomotor and somatosensory areas, occipital lobe, fusiform gyrus and thalamus during intervention was significantly greater in the CBM than in the control group. Furthermore, altered activities in the somatomotor and somatosensory areas, occipital lobe and posterior cingulate gyrus during interpreting ambiguous social situations showed a significant group × change in SA interaction. Our result suggests that when facing ambiguous social situations, positive imagery instilled by CBM-I is recalled, and interpretations are modified to contain social reward. These findings may help to suggest an alternative manner of enhancing CBM-I effectiveness from a cognitive-neuroscience perspective.

New Developments in Emotion-Focused Therapy for Social Anxiety Disorder

Social anxiety disorder (SAD) is a highly complex, chronic, disabling and costly anxiety disorder. Although cognitive-behavioral therapy (CBT) is effective for many patients, many others do not respond to CBT or remain considerably symptomatic at the end of treatment. Pharmacological effects are also modest. More empirically-supported treatment options are needed in order to increase patient access to effective treatment. Emotion-focused therapy (EFT) shows great promise in treating SAD effectively and is particularly suitable for treating SAD because pervasive emotional avoidance, difficulties with emotional differentiation, and high levels of self-criticism, which are central psychopathological processes in SAD, are also primary therapeutic targets in EFT. EFT is based on the assumption that the most efficient way to change a maladaptive emotion is not through reason or skill learning, but through the activation of other, more adaptive emotions. EFT aims to access shame-based emotional memories that underlie SAD, and transform them by exposing them to new adaptive emotional experiences, such as empowering assertive anger, grief, and self-compassion. In this paper, the core features of EFT for SAD are presented, as well as the EFT view of dysfunction in SAD and EFT change processes. Research findings regarding the effectiveness of EFT for SAD are presented together with initial findings regarding mechanisms of change occurring during treatment.

Age Moderates Link Between Training Effects and Treatment Response to Attention Bias Modification Treatment for Social Anxiety Disorder

Attention bias modification treatment (ABMT) aims to reduce anxiety symptoms via practice on computerized attention training tasks. Despite evidence of efficacy, clinical effects appear heterogeneous. More research on ABMT mechanisms and moderators of treatment response is needed. Age is one potentially important moderator, as developmental differences in training effects may impact response. We examined developmental links between ABMT training effects and response in social anxiety disorder (SAD). We pooled data from two randomized controlled trials in treatment-seeking youths and adults with SAD (N = 99) that used identical ABMT methods. We first characterized learning effects associated with the eight-session ABMT training protocol. We then tested whether learning magnitude predicted the clinical (change in SAD symptoms) and cognitive (change in attention bias) responses to treatment. Finally, we tested whether age moderated the association between ABMT learning and treatment response. Results indicate that ABMT was associated with an incremental learning curve during the protocol, and that learning improved with age. Age further moderated the association between learning gains during the ABMT protocol and subsequent reduction in self-reported SAD symptoms, such that this association was stronger with age. These effects were not evident in bias scores or clinician ratings. Finally, pre-treatment SAD symptoms and bias scores predicted ABMT learning gains. This study highlights the links among age, learning processes, and clinical response to ABMT. These insights may inform attempts to increase the clinical efficacy of ABMT for anxiety.

The effects of positive interpretation bias on cognitive reappraisal and social performance: Implications for social anxiety disorder

People with social anxiety disorder (SAD) lack non-socially anxious individuals' tendency to interpret ambiguous social information in a positively biased manner. To gain a better understanding of the specific in-vivo social consequences of positive interpretation bias, we recruited 38 individuals with SAD and 31 healthy controls (HC) to participate in an in-vivo social task. We tested whether a positive interpretation bias, measured using a sentence completion task, might confer benefits for the adaptive emotion regulation strategy of cognitive reappraisal, and whether such benefits depended on participants' emotional states. We also examined whether positive interpretation bias might confer additional benefits such as improved self-perceived and observer-rated social performance. In support of prior research, HC participants exhibited a positive interpretation bias on the sentence completion task, whereas participants with SAD did not. Regression analyses revealed that positive interpretation bias predicted greater cognitive reappraisal during social stress, particularly when state positive affect was low. Moreover, positive interpretation bias predicted more positive self-perception of social performance and reduced underestimations of performance relative to observer ratings. These results suggest that positive interpretations of ambiguous social information may be related to increased use of cognitive reappraisal and more positive self-perceptions of social performance.

Biased Perception of Physiological Arousal in Child Social Anxiety Disorder Before and After Cognitive Behavioral Treatment

Background

A biased perception of physiological hyperreactivity to social-evaluative situations is crucial for the maintenance of social anxiety disorder (SAD). Alterations in interoceptive accuracy (IAc) when confronted with social stressors may play a role for SAD in children. We expected a biased perception of hyperarousal in children with SAD before treatment and, consequently, a reduced bias after successful cognitive behavioral therapy (CBT).

Method

In two centers, 64 children with the diagnosis of SAD and 55 healthy control (HC) children (both 9 to 13 years) participated in the Trier Social Stress Test for Children (TSST-C), which was repeated after children with SAD were assigned to either a 12-week group CBT (n = 31) or a waitlist condition (n = 33). Perception of and worry about physiological arousal and autonomic variables (heart rate, skin conductance) were assessed. After each TSST-C, all children further completed a heartbeat perception task to assess IAc.

Results

Before treatment, children with SAD reported both a stronger perception of and more worry about their heart rate and skin conductance than HC children, while the objective reactivity of heart rate did not differ. Additionally, children with SAD reported heightened perception of and increased worry about trembling throughout the TSST-C compared to HC children, but reported increased worry about blushing only after the stress phase of the TSST-C compared to HC children. Children with and without SAD did not differ in IAc. Contrary to our hypothesis, after treatment, children in the CBT group reported heightened perception of physiological arousal and increased worry on some parameters after the baseline phase of the TSST-C, whereas actual IAc remained unaffected. IAc before and after treatment were significantly related.

Conclusions

Increased self-reported perception of physiological arousal may play a role in childhood SAD and could be an important target in CBT. However, further studies should examine if this is an epiphenomenon, a temporarily occurring and necessary condition for change, or indeed an unwanted adverse intervention effect.

Attentional Bias Modification in Virtual Reality - A VR-Based Dot-Probe Task With 2D and 3D Stimuli

Background

Attentional bias modification (ABM) aims to reduce anxiety by attenuating bias toward threatening information. The current study incorporated virtual reality (VR) technology and three-dimensional stimuli with a dot-probe task to evaluate the effects of a VR-based ABM training on attentional bias and anxiety symptoms.

Methods

A total of 100 participants were randomized to four training groups. Attentional bias was assessed at pre- and post-training, and anxiety symptoms were assessed at pre-training, post-training, 1-week follow-up, and 3-months follow-up.

Results

Change in anxiety did not correlate with change in bias (p = 0.24). A repeated-measures ANOVA showed no significant difference in bias from pre- to post-ABM (p = 0.144), or between groups (p = 0.976). For anxiety symptoms, a linear mixed-effects model analysis revealed a significant effect of time. Participants showed reduction in anxiety score at each successive assessment (p < 0.001). However, no other significant main effect or interactions were found. A clinically significant change analysis revealed that 9% of participants were classified as ‘recovered’ at 3-months follow-up.

Conclusion

A single session of VR-based ABM did not change attentional bias. The significant reduction in anxiety was not specific to active training, and the majority of participants remained clinically unchanged.

Visual attention to emotional faces in adolescents with social anxiety disorder receiving cognitive behavioral therapy

Social anxiety disorder (SAD) is a psychiatric condition that often onsets in childhood. Cognitive models underline the role of attention in the maintenance of SAD, but studies on youth populations are few, particularly those using eye tracking to measure attention. Cognitive behavioral therapy (CBT) for SAD includes interventions targeting attention, like exposure to eye contact, but the link between CBT and attention bias is largely unexplored. This study investigated attention bias in youth with SAD and the association with outcome from CBT. Latency to attend to pictures of faces with different emotions (vigilance) and latency to disengage from social stimuli (avoidance) was examined in N = 25 adolescents (aged 13–17) with SAD in relation to treatment outcome. Vigilance was operationalized as the time it took to relocate the gaze from a central position to a peripherally appearing social stimulus. The latency to disengage from a centrally located social stimulus, when a non-social stimulus appeared in the periphery, was used as a proxy for avoidance. Attention characteristics in the SAD group were compared to non-anxious (NA) controls (N = 22). Visual attention was measured using eye tracking. Participants in both the SAD and NA groups were vigilant towards angry faces, compared to neutral and happy faces. Similarly, both groups disengaged attention faster from angry faces. Adolescents with SAD who disengaged faster from social stimuli had less social anxiety after CBT. The results indicate that anxious youth display a vigilant-avoidant attention pattern to threat. However, partly inconsistent with previous research, the same pattern was observed in the NA group.

Therapeutic strategies for social anxiety disorder: where are we now?

Introduction: Classical well-established treatments of social anxiety disorder (SAD) are now complemented by more recent therapeutic strategies. This review aims to summarize available therapies for SAD and discuss recent evidence-based findings on the management of this disorder.Areas covered: Recent guidelines recommend psychotherapy, particularly cognitive-behavioral therapy (CBT), and pharmacotherapy, as first-line treatments of patients with SAD, without a clear superiority of one option over the other. CBT includes classical approaches such as in vivo exposure to social situations and cognitive therapy, but new modalities and techniques have been recently developed: third-wave approaches, internet-delivered therapy, virtual reality exposure, and cognitive bias modification. Selective serotonin reuptake inhibitors and serotonin-norepinephrine reuptake inhibitors have been also extensively studied and shown to be effective in SAD. Two alternative strategies have been developed to treat SAD with disappointing results: cognitive bias modification, and pharmacological augmentation of psychotherapy using D-cycloserine during exposure sessions.Expert opinion: Personalized treatments for SAD patients are now available. Innovative strategies such as online psychotherapy and virtual reality exposure are useful alternatives to CBT and SSRIs. Future developments and optimization of attention bias modification and of pharmacological augmentation of psychotherapy can be promising.

Brain structure changes induced by attention bias modification training

Attention bias modification (ABM) therapy aims to reduce anxiety by changing threat-related attention patterns using computerized training tasks. We examined changes in brain microstructure following ABM training. Thirty-two participants were randomly assigned to one of two training conditions: active ABM training shifting attention away from threat or attention control training involving no attention modification. Participants completed six lab visits, including five training sessions and three diffusion tensor imaging scans: immediately before and after the first training session, and at the end of the training series. Indices of local and global changes in microstructure and connectivity were measured. Significant longitudinal differences in fractional anisotropy (FA) between the active and control training regimens occurred in inferior temporal cortex. Changes in FA occurred across groups within ventromedial prefrontal cortex and middle occipital gyrus. These results indicate specific effects of active ABM on brain structure. Such changes could relate to clinical effects of ABM.

Statistical learning as a predictor of attention bias modification outcome: A preliminary study among socially anxious patients

Attention bias modification (ABM) is a novel therapy designed to modulate attentional biases towards threat typically observed among anxious individuals. Bias modification is allegedly achieved via extraction of a statistical regularity embedded within the treatment task. However, no prior study examined prediction of ABM therapeutic response in relation to patients' capacity to extract statistical properties from the environment, a capacity known as "statistical learning". Here, 30 treatment-seeking patients with social anxiety disorder completed a gold-standard statistical learning task at baseline and then received six sessions of ABM therapy. Results indicate that baseline statistical learning capacity predicts treatment outcome: the better patients' statistical learning capacity, the greater their reduction in clinician-rated and self-reported social anxiety symptoms. Restricted capacities for statistical learning could account for the moderate effect sizes of ABM therapy in clinical trials. Poor response may occur in patients who fail to extract the underlying contingency embedded in ABM.

Current Status of Cognitive Remediation for Psychiatric Disorders: A Review

Cognition is an important factor that affects daily functioning and quality of life. Impairment in cognitive function is a common symptom present in various psychological disorders, which hinders patients from functioning normally. Given that cognitive impairment has devastating effects, enhancing this in patients should lead to improvements in compromised quality of life and functioning, including vocational functioning. Over the past 50 years, several attempts have been made to improve impaired cognition, and empirical evidence for cognitive remediation (CR) has accumulated that supports its efficacy for treating schizophrenia. More recently, CR has been successfully applied in the treatment of depressive disorders, bipolar disorders, attention deficit/hyperactivity disorder, and anorexia nervosa. This study critically reviews recent CR studies and suggests their future direction. This study aimed to provide a modern definition of CR, and examine the current status of empirical evidence and representative CR programs that are widely used around the world.

Insula activation is modulated by attention shifting in social anxiety disorder

Social anxiety disorder (SAD) is characterized by exaggerated reactivity to social threat, often documented by biased attention to threatening information, and increased activation in brain regions involved in salience/threat processing. Attention training has been developed to ameliorate the attention bias documented in individuals with SAD, with mixed results. We investigated patterns of brain activation underlying acute attention modulation in 41 participants (29 with SAD and 12 health controls). We then investigated how brain activation changed over time in both groups in response to a 4-session attention training protocol (toward threat, away from threat, no-training control). Results revealed diminished pre-training deactivation in the insula in SAD participants during attention modulation. SAD participants also demonstrated an increase in insula deactivation over time, suggestive of an improvement in attention modulation of emotion, and this was associated with a decrease in symptom severity. Attention training did not, itself, lead to clinical improvement, though there was a trend level effect of training toward threat on increased insula deactivation over time. While deficits in attentional control and emotion modulation are documented in individuals with SAD, current attention training protocols are not robustly effective in ameliorating aberrant functioning. Pursuit of training protocols that have more robust impacts on the relevant neural circuitry may have some value.
