Unique relations among anxiety sensitivity factors and anxiety,depression, and suicidal ideation

Anxiety sensitivity (AS) is composed of three lower-order dimensions, cognitive concerns, physical concerns, and social concerns. We examined the relations between AS dimensions using a more adequate assessment of subscales (ASI-3) than has previously been used, and measures of anxiety and mood disorders as well as suicidal ideation in a sample of 256 (M age = 37.10 years, SD = 16.40) treatment-seeking individuals using structural equation modeling. AS cognitive concerns was uniquely associated with generalized anxiety disorder (GAD), obsessive–compulsive disorder (OCD), major depressive disorder (MDD), post-traumatic stress disorder (PTSD), and suicidal ideation. AS physical concerns was uniquely associated with OCD, social anxiety disorder (SAD), panic disorder (PD), and specific phobia. AS social concerns was uniquely associated with SAD, GAD, OCD, and MDD. These results highlight the importance of considering the lower-order AS dimensions when examining the relations between AS and psychopathology.     

Web-based therapist-assisted cognitive behavioral treatment of panic symptoms: A randomized controlled trial with a three-year follow-up

BackgroundInternet-delivered treatment may reduce barriers to care in those unwilling or unable to access traditional forms of treatment.ObjectiveTo assesses the efficacy of web-based therapist-assisted cognitive behavioral treatment (web-CBT) of panic symptoms.DesignA randomized waiting-list controlled trial with an uncontrolled three-year follow-up.ParticipantsA community sample of 58 participants with chronic panic symptoms of varying severity (immediate treatment: n = 27, waiting-list control: n = 31).Outcome measuresThe primary outcome measures were a one-week Panic Diary and the Panic Disorder Severity Scale – Self-Report (PDSS-SR); secondary measures were the Agoraphobic Cognitions Questionnaire (ACQ), the Body Sensations Questionnaire (BSQ), the Mobility Inventory – Alone subscale (MI-AAL), and the Depression Anxiety Stress Scales (DASS-42).ResultsIn the RCT, 54 participants (93%) completed posttest measurements. With regard to the primary outcome measures, intention-to-treat ANCOVAs revealed that participants in the treatment condition improved more than the participants in the waiting-list control condition (p < .03), with a pooled between-group effect size of d = .7. After three years (n = 47; 81% study compliance), effects were more pronounced.ConclusionThe results demonstrate the efficacy of therapist-assisted web-CBT in the treatment of panic symptoms.     

Transdiagnostic versus disorder-specific and clinician-guided versus self-guided internet-delivered treatment for Social Anxiety Disorder and comorbid disorders: A randomized controlled trial

Disorder-specific (DS-CBT) and transdiagnostic (TD-CBT) cognitive behaviour therapy have both been used to treat social anxiety disorder (SAD). This study compared internet-delivered DS-CBT and TD-CBT for SAD across clinician-guided (CG-CBT) and self-guided (SG-CBT) formats. Participants with SAD (n = 233) were randomly allocated to receive internet-delivered TD-CBT or DS-CBT and CG-CBT or SG-CBT. Large reductions in symptoms of SAD (Cohen’s d ≥ 1.01; avg. reduction ≥ 30%) and moderate-to-large reductions in symptoms of comorbid depression (Cohen’s d ≥ 1.25; avg. reduction ≥ 39%), generalised anxiety disorder (Cohen’s d ≥ 0.86; avg. reduction ≥ 36%) and panic disorder (Cohen’s d ≥ 0.53; avg. reduction ≥ 25%) were found immediately post-treatment and were maintained or further improved to 24-month follow-up. No marked differences were observed between TD-CBT and DS-CBT or CG-CBT and SG-CBT highlighting the potential of each for the treatment of SAD and comorbid disorders.     

Fearful responding to interoceptive exposure in social anxiety disorder

There is accumulating evidence suggesting that anxiety sensitivity (AS) may play a role in social anxiety disorder (SAD; e.g., Ball, Otto, Pollack, Uccello, & Rosenbaum, 1995). Precedent research has demonstrated the role of AS in panic disorder and posttraumatic stress disorder, and subsequently, treatment techniques aimed at reducing AS (i.e., interoceptive exposure (IE)) have been studied in these populations (Schmidt and Trakowski, 2004, Wald and Taylor, 2008). The purpose of this study was to examine the types of responses elicited during IE exercises among individuals with SAD. This study describes the responses of individuals with SAD (n = 37) and nonclinical control participants (n = 28) to six IE exercises. Significant differences in responses to the IE exercises were found between participants with SAD and nonclinical controls. However, there were no significant differences in responses to the exercises among persons with SAD, depending on whether the exercises were completed in private versus group settings. Similarity to symptoms during naturally occurring anxiety significantly predicted fearful responding across all exercises in persons with SAD. Implications and directions for future research are discussed.     

The relationship between anxiety disorders in adults and recalled childhood teasing

This study investigated the relationship between retrospective accounts of childhood teasing and anxiety disorders as well as the relationship between experiences of teasing and more global psychological well-being. Participants (N = 377) with social anxiety disorder (SAD), obsessive compulsive disorder (OCD), or panic disorder with or without agoraphobia (PD) were compared on levels of self-reported teasing history using the Teasing Questionnaire-Revised (TQ-R; Storch et al., 2004). Teasing frequency scores were higher for the SAD group compared to both PD and OCD groups. Across all groups, teasing scores were significantly related to increased social anxiety, depression, stress, and greater impairment in functioning. Teasing frequency accounted for unique variance in severity of SAD symptoms even after controlling for concurrent mood, anxiety and stress. These results support and extend previous findings linking childhood teasing to anxiety disorders in adulthood.     

Therapist-assisted Internet-delivered cognitive behavior therapy for depression and anxiety: Translating evidence into clinical practice

This dissemination study examined the effectiveness of therapist-assisted Internet-delivered Cognitive Behavior Therapy (ICBT) when offered in clinical practice. A centralized unit screened and coordinated ICBT delivered by newly trained therapists working in six geographically dispersed clinical settings. Using an open trial design, 221 patients were offered 12 modules of ICBT for symptoms of generalized anxiety (n = 112), depression (n = 83), or panic (n = 26). At baseline, midpoint and post-treatment, patients completed self-report measures. On average, patients completed 8 of 12 modules. Latent growth curve modeling identified significant reductions in depression, anxiety, stress and impairment (d = .65–.78), and improvements in quality of life (d = .48–.66). Improvements in primary symptoms were large (d = .91–1.25). Overall, therapist-assisted ICBT was effective when coordinated across settings in clinical practice, but further attention should be given to strategies to improve completion of treatment modules.     

The role of treatment delivery factors in exposure-based cognitive behavioral therapy for panic disorder with agoraphobia

Treatment delivery factors (i.e., therapist adherence, therapist competence, and therapeutic alliance) are considered to be important for cognitive behavioral therapy (CBT) for panic disorder and agoraphobia (PD/AG). In the current study, four independent raters conducted process evaluations based on 168 two-hour videotapes of 84 patients with PD/AG treated with exposure-based CBT. Two raters evaluated patients’ interpersonal behavior in Session 1. Two raters evaluated treatment delivery factors in Session 6, in which therapists provided the rationale for conducting exposure exercises. At the 6-month follow-up, therapists’ adherence (r = 0.54) and therapeutic alliance (r = 0.31) were significant predictors of changes in agoraphobic avoidance behavior; therapist competence was not associated with treatment outcomes. Patients’ interpersonal behavior in Session 1 was a significant predictor of the therapeutic alliance in Session 6 (r = 0.17). The findings demonstrate that treatment delivery factors, particularly therapist adherence, are relevant to the long-term success of CBT for PD/AG.     

Implicit associations in social anxiety disorder: The effects of comorbid depression

Implicit associations of the self to concepts like “calm” have been shown to be weaker in persons with social anxiety than in non-anxious healthy controls. However, other implicit self associations, such as those to acceptance or rejection, have been less studied in social anxiety, and none of this work has been conducted with clinical samples. Furthermore, the importance of depression in these relationships has not been well investigated. We addressed these issues by administering two Implicit Association Tests (IATs; Greenwald, McGhee, & Schwartz, 1998), one examining the implicit association of self/other to anxiety/calmness and the other examining the association of self/other to rejection/acceptance, to individuals with generalized social anxiety disorder (SAD, n = 85), individuals with generalized SAD and a current or past diagnosis of major depressive disorder or current dysthymic disorder (n = 47), and non-anxious, non-depressed healthy controls (n = 44). The SAD and SAD-depression groups showed weaker implicit self-calmness associations than healthy controls, with the comorbid group showing the weakest self-calmness associations. The SAD-depression group showed the weakest implicit self-acceptance associations; no difference was found between non-depressed individuals with SAD and healthy controls. Post hoc analyses revealed that differences appeared to be driven by those with current depression. The SAD-only and SAD-depression groups did not differ in self-reported (explicit) social anxiety. The implications of these findings for the understanding of SAD-depression comorbidity and for the treatment of SAD are considered.     

Disorder-specific versus transdiagnostic and clinician-guided versus self-guided treatment for major depressive disorder and comorbid anxiety disorders: A randomized controlled trial

Disorder-specific cognitive behavior therapy (DS-CBT) is effective at treating major depressive disorder (MDD) while transdiagnostic CBT (TD-CBT) addresses both principal and comorbid disorders by targeting underlying and common symptoms. The relative benefits of these two models of therapy have not been determined. Participants with MDD (n = 290) were randomly allocated to receive an internet delivered TD-CBT or DS-CBT intervention delivered in either clinician-guided (CG-CBT) or self-guided (SG-CBT) formats. Large reductions in symptoms of MDD (Cohen’s d ≥ 1.44; avg. reduction ≥ 45%) and moderate-to-large reductions in symptoms of comorbid generalised anxiety disorder (Cohen’s d ≥ 1.08; avg. reduction ≥ 43%), social anxiety disorder (Cohen’s d ≥ 0.65; avg. reduction ≥ 29%) and panic disorder (Cohen’s d ≥ 0.45; avg. reduction ≥ 31%) were found. No marked or consistent differences were observed across the four conditions, highlighting the efficacy of different forms of CBT at treating MDD and comorbid disorders.     

A meta-analysis and scoping review of social cognition performance in social phobia,posttraumatic stress disorder and other anxiety disorders

Social cognition deficits are observed in a variety of psychiatric illnesses. However, data concerning anxiety disorders are sparse and difficult to interpret. This meta-analysis aims at determining if social cognition is affected in social phobia (SP) or posttraumatic stress disorder (PTSD) compared to non-clinical controls and the specificity of such deficits relatively to other anxiety disorders. The scoping review aims to identify research gaps in the field. Forty studies assessing mentalizing, emotion recognition, social perception/knowledge or attributional style in anxiety disorders were included, totalizing 1417 anxious patients and 1321 non-clinical controls. Results indicate distinct patterns of social cognition impairments: people with PTSD show deficits in mentalizing (effect size d = −1.13) and emotion recognition (d = −1.6) while other anxiety disorders including SP showed attributional biases (d = −0.53 to d = −1.15). The scoping review identified several under investigated domains of social cognition in anxiety disorders. Some recommendations are expressed for future studies to explore the full range of social cognition in anxiety disorders and allow direct comparisons between different disorders.     

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.     

Relative effects of cognitive and behavioral therapies on generalized anxiety disorder,social anxiety disorder and panic disorder: A meta-analysis

Although cognitive and behavioral therapies are effective in the treatment of anxiety disorders, it is not clear what the relative effects of these treatments are. We conducted a meta-analysis of trials comparing cognitive and behavioral therapies with a control condition, in patients with social anxiety disorder (SAD), generalized anxiety disorder (GAD) and panic disorder. We included 42 studies in which generic measures of anxiety were used (BAI, HAMA, STAI-State and Trait). Only the effects of treatment for panic disorder as measured on the BAI (13.33 points; 95% CI: 10.58–16.07) were significantly (p = 0.001) larger than the effect sizes on GAD (6.06 points; 95% CI: 3.96–8.16) and SAD (5.92 points; 95% CI: 4.64–7.20). The effects remained significant after adjusting for baseline severity and other major characteristics of the trials. The results should be considered with caution because of the small number of studies in many subgroups and the high risk of bias in most studies.     

Meta-analysis of technology-assisted interventions for social anxiety disorder

This meta-analysis investigated the efficacy of technology-assisted interventions for individuals with social anxiety disorder (SAD). A systematic literature search in the databases Medline, PsychInfo, and Web of Science revealed 37 randomized controlled trials (2991 participants) that were grouped into internet delivered cognitive behavior therapy (ICBT; 21 trials), virtual reality exposure therapy (VRET; 3 trials), and cognitive bias modification (CBM; 13 trials). Patients undergoing ICBT and VRET showed significantly less SAD symptoms at postassessment than passive control conditions (g = 0.84 and 0.82, respectively). Compared to active control conditions, ICBT had a small advantage (g = 0.38) and VRET showed comparable effects (p > 0.05). CBM was not more effective than passive control conditions, except when delivered in the laboratory (g = 0.35). While the efficacy of CBM was limited, substantial evidence for ICBT and preliminary evidence for VRET suggests that both can effectively reduce SAD symptoms indicating the potential of technology-assisted interventions for SAD.     

Psychometric evaluation of the Concerns of Social Reprisal Scale: Further explicating the roots of fear of positive evaluation

Fear of positive evaluation (FPE) has been proposed to be an important feature of social anxiety disorder (SAD) and to be rooted, at least partly, in concerns of social reprisal due to positive impressions. In order to formally test this hypothesis, the Concerns of Social Reprisal Scale (CSRS) was developed. The purpose of the present series of studies was to examine the psychometric profile of the CSRS across several independent samples including: a large (n = 981) undergraduate sample; a clinical sample of individuals diagnosed with social anxiety disorder (n = 27), and a demographically-matched subsample of healthy control participants (n = 24). The factorial validity, internal consistency, and construct validity of the CSRS were examined. Results across both studies provided support for the psychometric profile of the CSRS. The implications of concerns of social reprisal for the assessment of social anxiety symptoms, theoretical models of fear of evaluation and SAD, and their potential clinical utility with regard to treating SAD are discussed.     

The SPAI-18, a brief version of the Social Phobia and Anxiety Inventory: Reliability and validity in clinically referred and non-referred samples

We developed a new version of the Social Phobia and Anxiety Inventory (SPAI) in order to have a brief instrument for measuring social anxiety and social anxiety disorder (SAD) with a strong conceptual foundation. In the construction phase, a set of items representing 5 core aspects of social anxiety was selected by a panel of social anxiety experts. The selected item pool was validated using factor analysis, reliability analysis, and diagnostic analysis in a sample of healthy participants (N = 188) and a sample of clinically referred participants diagnosed with SAD (N = 98). This procedure resulted in an abbreviated version of the Social Phobia Subscale of the SPAI consisting of 18 items (i.e. the SPAI-18), which correlated strongly with the Social Phobia Subscale of the original SPAI (both groups r = .98). Internal consistency and diagnostic characteristics using a clinical cut-off score > 48 were good to excellent (Cronbach's alpha healthy group = .93; patient group = .91; sensitivity: .94; specificity: .88). The SPAI-18 was further validated in a community sample of parents-to-be without SAD (N = 237) and with SAD (N = 65). Internal consistency was again excellent (both groups Cronbach's alpha = .93) and a screening cut-off of >36 proved to result in good sensitivity and specificity. The SPAI-18 also correlated strongly with other social anxiety instruments, supporting convergent validity. In sum, the SPAI-18 is a psychometrically sound instrument with good screening capacity for social anxiety disorder in clinical as well as community samples.     

Reduction of depersonalization during social stress through cognitive therapy for social anxiety disorder: A randomized controlled trial

Symptoms of depersonalization during feared social situations are commonly experienced by individuals with social anxiety disorder (SAD). Despite its clinical relevance, it is not addressed in standard treatment manuals and it remains unclear if depersonalization is reduced by well-established treatments. This study investigated whether cognitive therapy (CT) for SAD effectively reduces depersonalization and whether pre-treatment severity of depersonalization predicts or mediates treatment outcome.In a randomized controlled trial, patients underwent the standardized Trier Social Stress Test before and after CT (n = 20) or a waitlist period (n = 20) and were compared to healthy controls (n = 21). Self-reported depersonalization was measured immediately after each stress test.Depersonalization significantly decreased following CT, especially in treatment responders (η_p² = 0.32). Pre-treatment depersonalization did neither predict nor mediate post-treatment severity of social anxiety.Further prospective studies are needed for a better scientific understanding of this effect. It should be scrutinized whether SAD-patients suffering from depersonalization would benefit from a more specific therapy.     

Characteristics of responders and non-responders to risperidone monotherapy or placebo in co-occurring bipolar disorder and anxiety disorder

Clinical characteristics predicting response and remission to psychopharmacological treatment of bipolar disorder (BD) and co-occurring anxiety disorders have been understudied. We hypothesized that non-response to risperidone or placebo in individuals with co-occurring BD and anxiety symptoms would be associated with a more severe clinical course of BD, and certain demographic variables. This study was a secondary analysis of a randomized, double-blind, parallel, 8-week study comparing risperidone monotherapy and placebo in individuals with BD plus current panic disorder, current generalized anxiety disorder (GAD), or lifetime panic disorder (n = 111) [31]. We compared clinical characteristics of responders (50% improvement on the Hamilton Anxiety Scale [HAM-A]) and non-responders as well as remitters (HAM-A < 7) and non-remitters in risperidone treatment (n = 54) and placebo (n = 57) groups. For non-responders in the risperidone group, co-occurring lifetime panic disorder was significantly more common than for non-responders in the placebo group. Apart from this, no significant differences in course of illness or demographics were found either between or across groups for patients with BD and co-occurring anxiety symptoms receiving risperidone or placebo in this acute phase study.     

Cognitive behavior therapy versus interpersonal psychotherapy for social anxiety disorder delivered via smartphone and computer: A randomized controlled trial

In this study, a previously evaluated guided Internet-based cognitive behavior therapy for social anxiety disorder (SAD) was adapted for mobile phone administration (mCBT). The treatment was compared with a guided self-help treatment based on interpersonal psychotherapy (mIPT). The treatment platform could be accessed through smartphones, tablet computers, and standard computers. A total of 52 participants were diagnosed with SAD and randomized to either mCBT (n = 27) or mIPT (n = 25). Measures were collected at pre-treatment, during the treatment, post-treatment and 3-month follow-up. On the primary outcome measure, the Liebowitz Social Anxiety Scale – self-rated, both groups showed statistically significant improvements. However, mCBT performed significantly better than mIPT (between group Cohen's d = 0.64 in favor of mCBT). A larger proportion of the mCBT group was classified as responders at post-treatment (55.6% versus 8.0% in the mIPT group). We conclude that CBT for SAD can be delivered using modern information technology. IPT delivered as a guided self-help treatment may be less effective in this format.     

Disorder-specific versus transdiagnostic and clinician-guided versus self-guided internet-delivered treatment for panic disorder and comorbid disorders: A randomized controlled trial

Transdiagnostic cognitive behaviour therapy (TD-CBT) aims to target the symptoms of multiple disorders whereas disorder-specific CBT (DS-CBT) targets the symptoms of principal disorders. This study compared the relative benefits of internet-delivered TD-CBT and DS-CBT when provided in clinician-guided (CG-CBT) and self-guided (SG-CBT) formats for people with a principal diagnosis of Panic Disorder (PD). Participants (n = 145) were randomly allocated to receive TD-CBT or DS-CBT and CG-CBT or SG-CBT. Large reductions in symptoms of PD (Cohen's d ≥ 0.71; avg. reduction ≥ 36%) and moderate-to-large reductions in symptoms of comorbid depression (Cohen's d ≥ 0.71; avg. reduction ≥ 33%), generalised anxiety disorder (Cohen's d ≥ 0.91; avg. reduction ≥ 34%) and social anxiety disorder (Cohen's d ≥ 0.50; avg. reduction ≥ 15%) were found over the 24-month follow-up period. Highlighting their efficacy and acceptability, no marked and consistent differences were observed between TD-CBT and DS-CBT or CG-CBT and DS-CBT.
