ABSTRACT

OBJECTIVE: Eating disorders (EDs) often co-occur with social anxiety disorder (SAD). However, little research has examined the influence of SAD symptoms on ED treatment outcomes in the context of individual outpatient cognitive-behavior therapy for eating disorders (CBT-ED). It is plausible that SAD symptom severity could improve as a result of ED treatment, given the high overlap between EDs and SAD. We sought to test whether baseline SAD symptoms moderate early response to CBT-ED or post-treatment outcomes in CBT-ED, and the degree to which SAD symptoms improve during therapy despite SAD not being an explicit treatment target. METHOD: ED clients (N = 226) aged ≥16 years were treated with CBT-ED. Outcomes were ED symptoms, clinical impairment, and SAD symptoms measured at baseline, session 5 and post-treatment. RESULTS: Baseline SAD was a weak moderator of early and post-treatment ED symptoms and impairment. SAD symptoms improved moderately over treatment among clients who started with elevated levels of SAD symptomology. DISCUSSION: Clients with EDs can experience good therapeutic outcomes regardless of their social anxiety severity at pre-treatment. SAD symptoms reduced over CBT-ED, but protocol enhancements such as exposure-based strategies that directly target co-occurring social-evaluative concerns may help achieve larger reductions in SAD symptoms. PUBLIC SIGNIFICANCE: Eating disorders often co-occur with anxiety disorders such as social anxiety. We found people who had both social anxiety and an eating disorder benefited as much from eating disorder treatment as people who did not have social anxiety. People who were socially anxious became less anxious as a by-product of receiving eating disorder treatment. It may be possible to reduce social anxiety further by enhancing eating disorder treatment protocols.

ABSTRACT

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

ABSTRACT

Trials of cognitive behaviour therapy (CBT) for social anxiety disorder (SAD) have struggled to identify replicable moderators of treatment outcome. This could be due to a genuine lack of effects, or a spurious finding caused by methodological factors such as inadequate testing of theory-driven moderators, use of small homogenous samples, failure to model non-linear relationships, and over-reliance on significance testing. We probed explanations for the field's failure to detect moderators by testing whether 15 theory-driven and atheoretical variables moderated treatment outcome in a large heterogeneous sample treated with group CBT for SAD. Moderation was not assessed by only using p-values for linear models, but also by considering effect sizes, plots, and non-linear relationships. Despite using a comprehensive approach to assess moderation, only two variables - the baseline severity of SAD symptoms and fear of negative evaluation (FNE) - were found to moderate social anxiety symptom trajectories. FNE had a non-linear relationship with symptom change that would have been missed using common research methods. Our findings suggest both a genuine lack of effects and limitations of research methods have contributed to the field's inability to identify moderators. We provide suggestions that may increase the likelihood of future researchers detecting genuine effects.

ABSTRACT

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

ABSTRACT

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

ABSTRACT

BACKGROUND: The coronavirus pandemic (COVID-19) has required telehealth to be integrated into the delivery of evidence-based treatments for eating disorders in many services, but the impact of this on patient outcomes is unknown. OBJECTIVE: The present study examined the impact of the first wave of COVID-19 and rapid transition to telehealth on eating disorder symptoms in a routine clinical setting. METHOD: Participants were 25 patients with a confirmed eating disorder diagnosis who had commenced face-to-face treatment and rapidly switched to telehealth during the first wave of COVID-19 in Western Australia. Eating disorder symptoms, clinical impairment and mood were measured prospectively before and during lockdowns imposed due to COVID-19. HYPOTHESES: We predicted that patients would experience poorer treatment outcomes during COVID-19 and would perceive poorer therapeutic alliance and poorer quality of treatment compared to face-to-face therapy. RESULTS: Our hypotheses were not supported. On average, patients achieved large improvements in eating disorder symptoms and mood, and the magnitude of improvement in eating disorder symptoms was comparable to historical benchmarks at the same clinic. Patients rated the quality of treatment and therapeutic alliance highly. DISCUSSION: Providing evidence-based treatment for eating disorders via telehealth during COVID-19 lockdown is acceptable to patients and associated with positive treatment outcomes.

ABSTRACT

Repetitive negative thinking (RNT) is a transdiagnostic process that serves to maintain emotional disorders. Metacognitive theory suggests that positive and negative metacognitive beliefs guide the selection of RNT as a coping strategy which, in turn, increases psychological distress. The aim of this study was to test the indirect effect of metacognitive beliefs on psychological distress via RNT. Patients (N=52) with primary and non-primary generalized anxiety disorder attended a brief, six-week group metacognitive therapy program and completed measures of metacognitive beliefs, RNT, and symptoms at the first and final treatment sessions, and at a one-month follow-up. Prospective indirect effects models found that negative metacognitive beliefs (but not positive metacognitive beliefs) had a significant indirect effect on psychological distress via RNT. As predicted by metacognitive theory, targeting negative metacognitions in treatment appears to reduce RNT and, in turn, emotional distress. Further research using alternative measures at multiple time points during therapy is required to determine whether the absence of a relationship with positive metacognitive beliefs in this study was a consequence of (a) psychometric issues, (b) these beliefs only being relevant to a subgroup of patients, or (c) a lack of awareness early in treatment.

ABSTRACT

BACKGROUND: Generalized anxiety disorder (GAD) is a common and highly comorbid anxiety disorder characterized by repetitive negative thinking (RNT). Treatment trials tend to exclude individuals with non-primary GAD, despite this being a common presentation in real world clinics. RNT is also associated with multiple emotional disorders, suggesting that it should be targeted regardless of the primary disorder. This study evaluated the acceptability and effectiveness of brief group metacognitive therapy (MCT) for primary or non-primary GAD within a community clinic. METHODS: Patients referred to a specialist community clinic attended six, two-hour weekly sessions plus a one-month follow-up (N=52). Measures of metacognitive beliefs, RNT, symptoms, positive and negative affect, and quality of life were completed at the first, last, and follow-up sessions. RESULTS: Attrition was low and large intent-to-treat effects were observed on most outcomes, particularly for negative metacognitive beliefs and RNT. Treatment gains increased further to follow-up. Benchmarking comparisons demonstrated that outcomes compared favorably to longer disorder-specific protocols for primary GAD. LIMITATIONS: No control group or independent assessment of protocol adherence. CONCLUSIONS: Brief metacognitive therapy is an acceptable and powerful treatment for patients with primary or non-primary GAD.

ABSTRACT

Cognitive Behavioural Group Therapy (CBGT) for social phobia has been shown to be efficacious within research units and effective within a variety of real world clinical settings. However, most effectiveness studies of CBGT for social phobia have (a) used protocols without demonstrated efficacy, (b) not included direct comparison groups, and/or (c) contained features of efficacy trials. This study addressed these limitations by using a benchmarking strategy to compare outcomes from the same CBGT protocol used in both a research unit and a community clinic. Research (N = 71) and community (N = 94) patients completed the same 12-session protocol, which resulted in significant reductions in social anxiety and life interference at post-treatment. Compared to research unit patients, community patients had more severe symptoms and life interference at pre-treatment, and were more likely to be male, use medication, have comorbid disorders, and have lower educational attainment. Importantly, degree of improvement on social anxiety symptoms and life interference did not differ across the treatment settings for either completer or intention-to-treat analyses. There was some evidence that being younger, single, and having a depression diagnosis were associated with dropout. Pre-treatment symptoms and number of diagnoses predicted post-treatment symptoms. Consistent with previous uncontrolled trials, it is concluded that CBGT is effective within community mental health clinics.
