Fear of negative and positive evaluation as mediators and moderators of treatment outcome in social anxiety disorder.

INTRODUCTION: Elevated fear of negative evaluation (FNE) and fear of positive evaluation (FPE) are thought to play key roles in the maintenance of social anxiety disorder (SAD). Although efficacious therapies exist for SAD, the potential mediating and moderating effects of FNE and FPE on social anxiety treatment outcome have not been examined. METHODS: This sample comprised a secondary analysis of 210 individuals who participated in one of three randomized controlled trials for the treatment of SAD. Participants were randomized to: individual cognitive behavioral therapy (CBT), group CBT, community mindfulness-based stress reduction (MBSR), group MBSR, or they were randomized to waitlist and offered treatment after waitlist. Assessments were completed pre- and post-treatment/waitlist and, for the treatment groups, at three-month follow-up. RESULTS: CBT and MBSR led to greater reductions in FNE and FPE than waitlist, with CBT more efficacious in reducing FPE than MBSR. For both CBT (vs. waitlist) and MBSR (vs. waitlist), there were significant indirect effects on post-treatment social anxiety through both FNE and FPE, and the indirect effect through FPE was greater for CBT than MBSR. However, in the fully longitudinal model testing mediation, CBT and MBSR were not differentially mediated by FPE. Baseline FNE and FPE each moderated CBT treatment outcome compared to waitlist - higher baseline FNE and FPE were associated with higher baseline social anxiety and greater reductions in social anxiety during CBT. DISCUSSION: FNE and FPE contributed in sometimes similar and sometimes distinct ways to the mediation and moderation of psychosocial approaches for treating SAD. This supports the importance of distinguishing between fears of negative and positive evaluation in the assessment and treatment of SAD.

Aberrant cognitive empathy in individuals with elevated social anxiety and regulation with emotional working memory training.

Social anxiety may disrupt the empathic process, and well-regulated empathy is critical for navigating the social world. Two studies aimed to further understand empathy in the context of social anxiety. Study 1 compared individuals with elevated or normative social anxiety on a measure assessing cognitive and affective empathy for positive and negative emotions conveyed by other people ("targets"), completed under social threat. Relative to individuals with normative social anxiety, individuals with elevated social anxiety had greater cognitive empathy and no differences in affective empathy, regardless of emotion type. As greater cognitive empathy can be maladaptive, Study 2 tested whether this could be down-regulated. Individuals with elevated social anxiety underwent emotional working memory training (eWMT) for negative emotional information, or control training (CT). Effects on an empathy measure completed under social threat were assessed. Cognitive empathy for negative emotions decreased following eWMT but not CT, and this was only evident for those with higher pre-training working memory capacity. Cognitive empathy for positive emotions and affective empathy were not affected. Overall, social anxiety is associated with aberrant elevated cognitive empathy for negative and positive emotions, and the deviation in cognitive empathy for negative emotions can be regulated with eWMT for certain individuals.Trial registration: Australian New Zealand Clinical Trials Registry identifier: ACTRN12618001196235..

Optimized short-forms of the Cognitive Distortions Questionnaire.

INTRODUCTION: The Cognitive Distortions Questionnaire (CD-Quest) is a self-report questionnaire that assesses common cognitive distortions. Although the CD-Quest has excellent psychometric properties, its length may limit its use. METHODS: We attempted to develop short-forms of the CD-Quest using RiskSLIM - a machine learning method to build short-form scales that can be scored by hand. Each short-form was fit to maximize concordance with the total CD-Quest score for a specified number of items based on an objective function, in this case R2, by selecting an optimal subset of items and an optimal set of small integer weights. The models were trained in a sample of US undergraduate students (N = 906). We then validated each short-form on five independent samples: two samples of undergraduate students in Brazil (Ns = 182, 183); patients with depression in Brazil (N = 62); patients with social anxiety disorder in the US (N = 198); and psychiatric outpatients in Turkey (N = 269). RESULTS: A 9-item short-form with integer scoring was created that reproduced the total 15-item CD-Quest score in all validation samples with excellent accuracy (R2 = 90.4-93.6%). A 5-item ultra-short-form had good accuracy (R2 = 78.2-85.5%). DISCUSSION: A 9-item short-form and a 5-item ultra-short-form of the CD-Quest both reproduced full CD-Quest scores with excellent to good accuracy. These shorter versions of the full CD-Quest could facilitate measurement of cognitive distortions for users with limited time and resources.

Assessing and improving public mental health literacy concerning rTMS.

BACKGROUND: Repetitive transcranial magnetic stimulation (rTMS) has received empirical support as a viable treatment alternative for treatment-resistant major depressive disorder. Nevertheless, patients and the public-at-large may be hesitant to adopt rTMS. In three studies, we sought to (1) assess and (2) improve public perceptions of rTMS as a treatment for depression. METHODS: In Study 1 (N = 107), we administered questionnaires on Amazon's Mechanical Turk (MTurk) to individuals from the US and Canada in a cross-sectional design to assess perceptions of rTMS compared to psychopharmacology, electroconvulsive therapy (ECT), and talk therapy. In Study 2 (N = 106), we again used an MTurk sample and a cross-sectional design to assess perceptions of rTMS after providing participants with a relatively long description of rTMS. In Study 3 (N = 308), we conducted an experiment in undergraduate students. Participants were randomized to one of four experimental conditions manipulating participants' understanding of the causal mechanisms of depression prior to assessing their perceptions of rTMS. RESULTS: Public perceptions of rTMS were more negative than pharmacotherapy and talk therapy but not ECT (Study 1). rTMS perceptions were notably better when participants were given thorough information about rTMS procedures, pain, and side-effects (Study 2), compared to the previous study when they were given a very brief description of rTMS. Finally, perceptions of rTMS were significantly better when participants were given a brain circuitry-based causal explanation of depression compared to when they were given a psychological explanation of the causes of depression (Study 3). CONCLUSIONS: Public perceptions of rTMS are relatively poor. To improve rTMS acceptability, practitioners should carefully consider patients' prior attitudes and beliefs when explaining rTMS as a treatment alternative. Given that beliefs can have powerful effects on treatment outcome (e.g., placebo, nocebo), future research should explore whether rTMS effects on depression can be improved by facilitating less negative perceptions of rTMS.

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.

Sleep quality and treatment of social anxiety disorder.

Background and Objectives: Poor sleep is prevalent among individuals with social anxiety disorder (SAD) and may affect treatment outcome. We examined whether: (1) individuals with SAD differed from healthy controls (HCs) in sleep quality, (2) baseline sleep quality moderated the effects of treatment (Cognitive-behavioral group therapy [CBGT] vs. mindfulness-based stress reduction [MBSR] vs. waitlist [WL]) on social anxiety, (3) sleep quality changed over treatment, and (4) changes in sleep quality predicted anxiety 12-months post-treatment. Design: Participants were 108 adults with SAD from a randomized controlled trial of CBGT vs. MBSR vs. WL and 38 HCs. Methods: SAD and sleep quality were assessed pre-treatment and post-treatment; SAD was assessed again 12-months post-treatment. Results: Participants with SAD reported poorer sleep quality than HCs. The effect of treatment condition on post-treatment social anxiety did not differ as a function of baseline sleep quality. Sleep quality improved in MBSR, significantly more than WL, but not CBGT. Sleep quality change from pre- to post-treatment in CBGT or MBSR did not predict later social anxiety. Conclusions: MBSR, and not CBGT, improved sleep quality among participants. Other results were inconsistent with prior research; possible explanations, limitations, and implications for future research are discussed. ClinicalTrials.gov identifier: NCT02036658.

Does centrality in a cross-sectional network suggest intervention targets for social anxiety disorder?

OBJECTIVE: Network analysis allows us to identify the most interconnected (i.e., central) symptoms, and multiple authors have suggested that these symptoms might be important treatment targets. This is because change in central symptoms (relative to others) should have greater impact on change in all other symptoms. It has been argued that networks derived from cross-sectional data may help identify such important symptoms. We tested this hypothesis in social anxiety disorder. METHOD: We first estimated a state-of-the-art regularized partial correlation network based on participants with social anxiety disorder (n = 910) to determine which symptoms were more central. Next, we tested whether change in these central symptoms were indeed more related to overall symptom change in a separate dataset of participants with social anxiety disorder who underwent a variety of treatments (n = 244). We also tested whether relatively superficial item properties (infrequency of endorsement and variance of items) might account for any effects shown for central symptoms. RESULTS: Centrality indices successfully predicted how strongly changes in items correlated with change in the remainder of the items. Findings were limited to the measure used in the network and did not generalize to three other measures related to social anxiety severity. In contrast, infrequency of endorsement showed associations across all measures. CONCLUSIONS: The transfer of recently published results from cross-sectional network analyses to treatment data is unlikely to be straightforward.

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.

The Cognitive Distortions Questionnaire (CD-Quest): Validation in a Sample of Adults with Social Anxiety Disorder.

Cognitive distortions are thought to be central to the development and maintenance of anxiety disorders and are a widely acknowledged treatment target in cognitive-behavioral interventions. However, little research has focused on the measurement of cognitive distortions. The Cognitive Distortions Questionnaire (CD-Quest; de Oliveira, 2015), a brief, 15-item questionnaire, assesses the frequency and intensity of cognitive distortions. The CD-Quest has been shown to have sound psychometric properties in American, Australian, and Brazilian undergraduate samples and one Turkish-speaking outpatient clinical sample. The current study aimed to provide the first evaluation of the psychometric properties of the English version of the CD-Quest in a clinical sample and the first evaluation of any version of the CD-Quest in a sample of adults diagnosed with social anxiety disorder (SAD). In a sample of treatment-seeking adults with SAD, the CD-Quest demonstrated good convergent validity, discriminant validity, known-groups validity, and treatment sensitivity. It also showed good internal consistency, and both confirmatory and exploratory factor analyses supported the previously reported unitary factor structure. Findings extend prior research indicating the reliability and validity of the CD-Quest.

Positive and Negative Affect as Links Between Social Anxiety and Depression: Predicting Concurrent and Prospective Mood Symptoms in Unipolar and Bipolar Mood Disorders.

The co-occurrence of social anxiety and depression is associated with increased functional impairment and a more severe course of illness. Social anxiety disorder is unique among the anxiety disorders in sharing an affective profile with depression, characterized by low levels of positive affect (PA) and high levels of negative affect (NA). Yet it remains unclear how this shared affective profile contributes to the covariation of social anxiety and depressive symptoms. We examined whether self-reported PA and NA accounted for unique variance in the association between social anxiety and depressive symptoms across three groups (individuals with remitted bipolar disorder, type I [BD; n = 32], individuals with remitted major depressive disorder [MDD; n = 31], and nonpsychiatric controls [n = 30]) at baseline and follow-ups of 6 and 12 months. Low levels of PA, but not NA, accounted for unique variance in both concurrent and prospective associations between social anxiety and depression in the BD group; in contrast, high levels of NA, but not PA, accounted for unique variance in concurrent and prospective associations between social anxiety and depression in the MDD group. Limitations include that social anxiety and PA/NA were assessed concurrently and all measurement was self-report. Few individuals with MDD/BD met current diagnostic criteria for social anxiety disorder. There was some attrition at follow-up assessments. Results suggest that affective mechanisms may contribute to the high rates of co-occurrence of social anxiety and depression in both MDD and BD. Implications of the differential role of PA and NA in the relationship between social anxiety and depression in MDD and BD and considerations for treatment 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.

Empathy for positive and negative emotions in social anxiety disorder.

Social anxiety disorder (SAD) is associated with elevated negative and diminished positive affective experience. However, little is known about the way in which individuals with SAD perceive and respond emotionally to the naturally-unfolding negative and positive emotions of others, that is, cognitive empathy and affective empathy, respectively. In the present study, participants with generalized SAD (n = 32) and demographically-matched healthy controls (HCs; n = 32) completed a behavioral empathy task. Cognitive empathy was indexed by the correlation between targets' and participants' continuous ratings of targets' emotions, whereas affective empathy was indexed by the correlation between targets' and participants' continuous self-ratings of emotion. Individuals with SAD differed from HCs only in positive affective empathy: they were less able to vicariously share others' positive emotions. Mediation analyses revealed that poor emotional clarity and negative interpersonal perceptions among those with SAD might account for this finding. Future research using experimental methodology is needed to examine whether this finding represents an inability or unwillingness to share positive affect.

Social anxiety and vulnerability for problematic drinking in college students: the moderating role of post-event processing.

Socially anxious college students are at increased risk for engaging in problematic drinking (i.e. heavy or risky drinking) behaviors that are associated with the development of an alcohol use disorder. The present study examined whether post-event processing (PEP), repeatedly thinking about and evaluating one's performance in a past social situation, strengthens the association between social anxiety and vulnerability to problematic drinking among college students. Eighty-three college drinkers with high or low social anxiety participated in a social interaction task and were exposed to a manipulation that either promoted or inhibited PEP about the social interaction. Among participants randomized to the PEP promotion condition, those with high social anxiety exhibited a greater urge to use alcohol after the social interaction and greater motivation to drink to cope with depressive symptoms over the week following the manipulation than did those with low social anxiety. These findings suggest that targeting PEP in college drinking intervention programs may improve the efficacy of such programs for socially anxious students.

Anxiety trajectories in response to a speech task in social anxiety disorder: Evidence from a randomized controlled trial of CBT.

The subjective experience of anxiety plays a central role in cognitive behavioral models of social anxiety disorder (SAD). However, much remains to be learned about the temporal dynamics of anxiety elicited by feared social situations. The aims of the current study were: (1) to compare anxiety trajectories during a speech task in individuals with SAD (n=135) versus healthy controls (HCs; n=47), and (2) to compare the effects of CBT on anxiety trajectories with a waitlist control condition. SAD was associated with higher levels of anxiety and greater increases in anticipatory anxiety compared to HCs, but not differential change in anxiety from pre- to post-speech. CBT was associated with decreases in anxiety from pre- to post-speech but not with changes in absolute levels of anticipatory anxiety or rates of change in anxiety during anticipation. The findings suggest that anticipatory experiences should be further incorporated into exposures.

Social Anxiety and Misinterpretation of the Five Facet Mindfulness Questionnaire Describe Subscale.

The Five Facet Mindfulness Questionnaire is a widely used measure assessing 5 aspects of mindfulness. The Describe subscale is intended to assess the ability to put one's inner experience into words for one's own understanding, but subscale items contain language that may be ambiguous in that regard. The current study investigated whether social anxiety is associated with a tendency to misinterpret Describe items as referring to describing one's experiences to others rather than oneself. Participants were randomized to receive one of 3 versions of the Describe subscale: the original version or one of two variants orienting participants to describe inner experience for self-communication or interpersonal communication. Social anxiety was negatively associated with Describe scores for the Standard Describe subscale and the interpersonal communication variant, but not for the self-communication variant. Results suggest that high levels of social anxiety are associated with misinterpretation of statements on the Describe subscale as probing for interpersonal communication.

Attentional blink impairment in social anxiety disorder: Depression comorbidity matters.

BACKGROUND AND OBJECTIVES: Difficulties with attentional control have long been thought to play a key role in anxiety and depressive disorders. However, the nature and extent of attentional control difficulties in social anxiety disorder (SAD) are not yet well understood. The current study was designed to assess whether attentional control for non-emotional information is impaired in SAD when taking comorbid depression into account.. METHODS: Individuals with SAD and healthy controls (HCs) were administered an attentional blink (AB) task in which they identified number targets in a rapid serial visual presentation stream of letters. RESULTS: Individuals with SAD and current comorbid depression exhibited reduced accuracy to identify a target that fell within the AB window after the presentation of a first target compared to individuals with SAD without current comorbid depression, as well as to HCs. The latter two groups did not differ from each other, and the three groups did not differ in accuracy for the second target when it was presented after the AB window. LIMITATIONS: Although we included two clinical groups and the sample size for the non-comorbid SAD group was large, the comorbid SAD group was relatively small. CONCLUSIONS: These results suggest that impaired attentional control among individuals with SAD may be limited to those suffering from current comorbid depression..

The Social Interaction Phobia Scale: Continued support for the psychometric validity of the SIPS using clinical and non-clinical samples.

The present study sought to extend findings supporting the psychometric validity of a promising measure of social anxiety (SA) symptoms, the Social Interaction Phobia Scale (SIPS; Carleton et al., 2009). Analyses were conducted using three samples: social anxiety disorder (SAD) patients, generalized anxiety disorder (GAD) patients, and healthy controls. SIPS scores of SAD patients demonstrated internal consistency and construct validity, and the previously demonstrated three-factor structure of the SIPS was replicated. Further, the SIPS total score uniquely predicted SA symptoms, and SIPS scores were significantly higher for SAD patients than GAD patients or controls. Two cut-off scores that discriminated SAD patients from GAD patients and from healthy controls were identified. The current study is the first to replicate the SIPS three-factor model in a large, treatment-seeking sample of SAD patients and establish a cut-off score discriminating SAD from GAD patients. Findings support the SIPS as a valid, SAD-specific assessment instrument.
