RESUMEN
OBJECTIVE: Interpersonal problems have been identified as a plausible mechanism underlying the onset and maintenance of eating disorders. The Interpersonal Relationships in Eating Disorders (IR-ED) scale is the first eating disorders-specific measure of interpersonal problems, which was developed in a nonclinical sample. The aims of the current study were to (a) confirm the factor structure of the IR-ED within a large clinical sample, (b) investigate measurement invariance of the IR-ED across nonclinical and clinical samples, (c) examine the convergent validity of the IR-ED using a generic measure of interpersonal problems, and (d) investigate the incremental clinical utility of the IR-ED in uniquely predicting eating disorder symptomatology. METHOD: Treatment-seeking individuals (N = 437) completed the IR-ED at their initial assessment appointment at a specialist eating disorder outpatient service. RESULTS: A multiple-group confirmatory factor analysis supported an invariant bifactor structure comprising a general interpersonal problems factor and two group factors-Avoidance of Body Evaluation and Food-Related Interpersonal Tension. Convergent validity was demonstrated by a large, statistically significant correlation with a generic measure of interpersonal problems (r = 0.62, p < 0.001). A series of structural equation models further revealed unique incremental predictive utility of the IR-ED for eating disorder symptomatology. DISCUSSION: The IR-ED has strong psychometric properties and may prove beneficial in the assessment, formulation, and treatment of eating-specific interpersonal problems among patients with eating disorders.
RESUMEN
OBJECTIVE: Shame is a powerful self-conscious emotion that is often experienced by individuals with eating disorders (EDs). While the association between EDs and shame is well-established, there is limited research investigating the contribution of pre-treatment shame to clinical outcomes. METHOD: Participants (N = 273) received outpatient cognitive-behavioral therapy for eating disorders (CBT-ED). We investigated pre-treatment shame as a predictor of dropout and as a moderator of change in ED psychopathology and clinical impairment from pre-treatment to post-treatment. We also explored the potentially moderating roles of body mass index, ED diagnostic category, and co-occurring anxiety and depression diagnoses. RESULTS: Shame improved substantially (d = 1.28) despite not being explicitly targeted in treatment. Pre-treatment shame did not predict treatment dropout. Individuals high in shame started and ended treatment with higher ED symptoms and impairment than those with low shame. The contribution of pre-treatment shame on the degree of change in symptoms/impairment depended critically on whether analyses controlled for pre-treatment symptoms/impairment. When those were controlled, high pre-treatment shame was associated with substantially less improvement in ED symptoms and impairment. There was some evidence that ED diagnosis and co-occurring depressive diagnoses may moderate the relationship between shame and treatment outcome. Changes in shame were positively associated with changes in ED symptoms and clinical impairment. DISCUSSION: A high level of shame at pre-treatment is not a contraindication for CBT-ED as good therapeutic outcomes can be achieved. However, outcomes may be enhanced among individuals high in shame by offering adjunctive interventions that explicitly target shame.
RESUMEN
OBJECTIVE: To examine rates and predictors of attrition from referral through to treatment completion in an outpatient public psychology service's eating disorder program in Perth, Western Australia. METHOD: The proportion (number) of clients (N = 671; mean age = 23.8 years) transitioning between stages of pre-treatment and treatment was identified. Associations between demographic, treatment and clinical variables and attrition were investigated using logistic regression. RESULTS: Only 34% (n = 230) of referred patients started treatment and 16% (n = 107) completed treatment. Referral acceptance was correlated with provisional diagnoses that meet the service's inclusion criteria, and attendance at an initial assessment was correlated with younger age. Treatment commencement was correlated with the presence of a co-occurring depressive or anxiety disorder, and no previous suicide attempts. Completing a full course of treatment was correlated with no previous hospitalisation for psychiatric issues, no previous suicide attempts, a history of psychiatric medication use, and treatment with family-based therapy. DISCUSSION: High rates of attrition were found from referral to treatment completion. A suggested framework for defining the different stages of attrition is proposed to allow for consistency of attrition reporting across the mental health field. Future studies are needed to identify why clients disengage following referral, assessment, and treatment commencement, to inform strategies to engage and sustain engagement and to optimise outcomes.
RESUMEN
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.
RESUMEN
Evidence-based cognitive-behaviour therapy for eating disorders (CBT-ED) differs from other forms of CBT for psychological disorders, making existing generic CBT measures of therapist competence inadequate for evaluating CBT-ED. This study developed and piloted the reliability of a novel measure of therapist competence in this domain-the Cognitive Behaviour Therapy Scale for Eating Disorders (CBTS-ED). Initially, a team of CBT-ED experts developed a 26-item measure, with general (i.e. present in every session) and specific (context- or case-dependent) items. To determine statistical properties of the measure, nine CBT-ED experts and eight non-experts independently observed six role-played mock CBT-ED therapy sessions, rating the therapists' performance using the CBTS-ED. The inter-item consistency (Cronbach's alpha and McDonald's omega) and inter-rater reliability (ICC) were assessed, as appropriate to the clustering of the items. The CBTS-ED demonstrated good internal consistency and moderate/good inter-rater reliability for the general items, at least comparable to existing generic CBT scales in other domains. An updated version is proposed, where five of the 16 "specific" items are reallocated to the general group. These preliminary results suggest that the CBTS-ED can be used effectively across both expert and non-expert raters, though less experienced raters might benefit from additional training in its use.

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.

OBJECTIVE: The coronavirus pandemic has led to a dramatically different way of working for many therapists working with eating disorders, where telehealth has suddenly become the norm. However, many clinicians feel ill equipped to deliver therapy via telehealth, while adhering to evidence-based interventions. This article draws together clinician experiences of the issues that should be attended to, and how to address them within a telehealth framework. METHOD: Seventy clinical colleagues of the authors were emailed and invited to share their concerns online about how to deliver cognitive-behavioral therapy for eating disorders (CBT-ED) via telehealth, and how to adapt clinical practice to deal with the problems that they and others had encountered. After 96 hr, all the suggestions that had been shared by 22 clinicians were collated to provide timely advice for other clinicians. RESULTS: A range of themes emerged from the online discussion. A large proportion were general clinical and practical domains (patient and therapist concerns about telehealth; technical issues in implementing telehealth; changes in the environment), but there were also specific considerations and clinical recommendations about the delivery of CBT-ED methods. DISCUSSION: Through interaction and sharing of ideas, clinicians across the world produced a substantial number of recommendations about how to use telehealth to work with people with eating disorders while remaining on track with evidence-based practice. These are shared to assist clinicians over the period of changed practice.

OBJECTIVE: Interventions for carers of individuals with eating disorders are often time and resource intensive, which may be a barrier for service providers or attendees. This study aimed to evaluate the efficacy of a very brief, two-session psychoeducation and communication skills-based intervention for carers of individuals with eating disorders. METHOD: Carers (N = 44) were randomized to attend two 2.5 hr sessions delivered 1 week apart or waitlist control. Carer burden, self-efficacy, skills, knowledge, expressed emotion (emotional overinvolvement and critical comments), distress (anxiety and depression), and accommodating and enabling behaviors were assessed at preintervention and postintervention and 1-month follow-up. RESULTS: Carer burden, self-efficacy, skills, knowledge, and one component of expressed emotion (critical comments) improved significantly more in the treatment group compared to the waitlist. Changes in anxiety, depression, and accommodating and enabling behaviors did not significantly differ between groups. DISCUSSION: These results demonstrated that substantial improvements can be made from a very brief carers' intervention. More intensive and targeted interventions might be required to address carers' emotional symptoms and to reduce accommodating and enabling behaviors.

Behavioral methods are inherent in many evidence-based treatments of eating disorders and have also been used separately. This review demonstrates that behavioral methods are necessary in the effective treatment of eating disorders-in particular, the improvement of nutrition and exposure-based methods. It is also possible that these methods are sufficient to treat anorexia nervosa, although other elements are needed on the treatment of bulimia nervosa. The impacts and mechanisms of behavioral and nutritional change merit serious attention in clinical work and research. Clinicians are often reluctant, however, to use these methods, and that needs to be the focus of supervision.

Aim: The Clinical Impairment Assessment (CIA 3.0) is the most widely used instrument assessing psychosocial impairment secondary to eating disorder symptoms. However, there is conflicting advice regarding the dimensionality and optimal method of scoring the CIA. We sought to resolve this confusion by conducting a comprehensive factor analytic study of the CIA in a community sample (N = 301) and clinical sample comprising patients with a diagnosed eating disorder (N = 209). Convergent and discriminant validity were also assessed. Method: The CIA and measures of eating disorder symptoms were administered to both samples. Results: Factor analyses indicated there is a general impairment factor underlying all items on the CIA that is reliably measured by the CIA Global score. CIA Global demonstrated good convergent and discriminant validity. Conclusions: CIA Global is a reliable and valid measure of psychosocial impairment secondary to eating disorder symptoms; however, subscale scores should not be computed.

Clinical reports suggest that interpersonal problems are associated with the onset and maintenance of eating pathology, but existing measures of such problems have limited links to eating pathology. Therefore, the aim of this study was to develop an eating-specific measure of interpersonal problems. The new measure, the Interpersonal Relationships in Eating Disorders scale (IR-ED), was administered to a large community sample, a nonclinical replication sample, and a clinical group of eating disorder patients. In Study 1, the psychometric properties of the IR-ED were established, and they were tested using confirmatory analyses in Study 2. Study 3 determined the validity of the test score interpretations in a clinical sample. The final 15-item version of the IR-ED demonstrated 3 distinct factors with reliability of test scores-Food-Related Isolation; Avoidance of Body Evaluation; and Food-Related Interpersonal Tension. Study 2 demonstrated that the IR-ED comprises a common Interpersonal Problems factor and a specific group factor-Avoidance of Body Evaluation. Study 3 showed that the clinical group had higher IR-ED scores than a nonclinical group. Across the studies, Avoidance of Body Evaluation was the strongest correlate of eating pathology in this group. The IR-ED has strong psychometric properties and its test scores appear to be more valid than those of a generic measure of interpersonal problems. Avoidance of Body Evaluation is the strongest facet of such interpersonal problems, and has meaningful links to models of eating psychopathology.

OBJECTIVE: Clinical perfectionism is involved in the etiology and maintenance of eating disorders. Limited research has examined the factor structure of the Clinical Perfectionism Questionnaire (CPQ) in clinical eating disorder samples. The aim of this research was to examine the validity and reliability of the CPQ in a mixed eating disorder sample. METHOD: Patients (N = 211) with an eating disorder completed the CPQ at pretreatment. A bifactor model was tested that included a general clinical perfectionism factor and two group factors; overevaluation of striving and concern over mistakes. The unique contributions that general and group factors make to the prediction of eating disorder symptoms were also investigated. Unidimensional, correlated two-factor, and bifactor models were tested using confirmatory factor analysis. RESULTS: A bifactor structure for a revised 10-item version of the CPQ provided the best fit, with a strong and reliable general clinical perfectionism factor. The general clinical perfectionism factor and the overevaluation of striving group factor explained reliable variance in the CPQ, and but only the general factor predicted eating disorder symptoms. DISCUSSION: The results suggested that a total score is generally appropriate for assessing clinical perfectionism in a clinical eating disorder sample.

OBJECTIVE: The present study aimed to examine whether Anorexia Nervosa (AN) illness severity or duration is associated with retention or treatment response in outpatient, enhanced cognitive-behavioral therapy (CBT-E). METHOD: Patients with a confirmed AN diagnosis (N = 134) completed measures of eating disorder symptoms and quality of life, and had their BMI objectively measured before, during, and after treatment. We evaluated whether illness severity or duration predicted treatment outcomes, using longitudinal regression models. RESULTS: Greater levels of illness severity and duration were not associated with poorer treatment outcomes. CONCLUSIONS: Patients with more severe or long-standing AN illness did just as well in CBT-E as any other patient starting treatment. Therefore, classifying individuals as "severe and enduring" appears to lack clinical utility in CBT-E. Clinicians should continue to administer evidence-supported treatments such as CBT-E for patients with AN, regardless of duration or severity of AN illness. (PsycINFO Database Record

OBJECTIVE: The present study evaluated the relative clinical validity of two interpersonal models of the maintenance of eating disorders, IPT-ED (Rieger et al., ) and the interpersonal model of binge eating (Wilfley, MacKenzie, Welch, Ayres, & Weissman, ; Wilfley, Pike, & Striegel-Moore, ). While both models propose an indirect relationship between interpersonal problems and eating disorder symptoms via negative affect, IPT-ED specifies negative social evaluation as the key interpersonal problem, and places greater emphasis on the role of low self-esteem as an intermediate variable between negative social evaluation and eating pathology. METHOD: Treatment-seeking individuals (N = 306) with a diagnosed eating disorder completed measures of socializing problems, generic interpersonal problems, self-esteem, eating disorder symptoms, and negative affect (depression and anxiety). Structural equation models were run for both models. RESULTS: Consistent with IPT-ED, a significant indirect pathway was found from socializing problems to eating disorder symptoms via low self-esteem and anxiety symptoms. There was also a direct pathway from low self-esteem to eating disorder symptoms. Using a socializing problems factor in the model resulted in a significantly better fit than a generic interpersonal problems factor. Inconsistent with both interpersonal models, the direct pathway from socializing problems to eating disorder symptoms was not supported. DISCUSSION: Interpersonal models that included self-esteem and focused on socializing problems (rather than generic interpersonal problems) explained more variance in eating disorder symptoms. Future experimental, prospective, and treatment studies are required to strengthen the case that these pathways are causal.

Contemporary models of eating disorders suggest that interpersonal problems contribute to the maintenance of eating disorders. This study examined whether baseline interpersonal problems differed across eating disorder diagnoses and across eating disorder subtypes ("restrictors" vs. "binge-purge" patients) in a large clinical sample. Patients with a primary eating disorder diagnosis (N=406) completed measures of interpersonal problems, eating disorder symptoms, and mood prior to treatment at a specialist eating disorder clinic. Across the sample, more severe eating disorder psychopathology was associated with significantly greater difficulty socializing. Anorexia Nervosa (AN)/restrictor patients reported significantly greater difficulty socializing than Bulimia Nervosa (BN)/binge-purge patients. AN patients reported significantly greater difficulty on a measure of competitiveness/assertiveness compared to BN and Eating Disorder Not Otherwise Specified patients. All findings were significant after controlling for comorbid depression and anxiety symptoms. Interpersonal problems appear to be unique risk factors for eating disorders. Specific interpersonal mechanisms include difficulties socializing and being assertive, which were most pronounced in AN patients. These findings provide potential avenues for enhancing interventions, such as adjunctive assertiveness training for AN.

The present paper assessed therapeutic alliance over the course of Enhanced Cognitive Behavioural Therapy (CBT-E) in a community-based sample of 112 patients with a diagnosis of bulimia nervosa (BN) or atypical BN. Temporal assessment of alliance was conducted at three time points (the start, middle and end of treatment) and the relationship between alliance and treatment retention and outcome was explored. Results indicated that the alliance between patient and therapist was strong at all stages of CBT-E, and even improved in the early stages of treatment when behaviour change was initiated (weekly in-session weighing, establishing regular eating, and ceasing binge-eating and compensatory behaviours). The present study found no evidence that alliance was related to treatment retention or outcomes, or that symptom severity or problematic interpersonal styles interacted with alliance to influence outcomes. Alliance was also unrelated to baseline emotional or interpersonal difficulties. The study provides no evidence that alliance has clinical utility for the prediction of treatment retention or outcome in CBT-E for BN, even for individuals with severe symptoms or problematic interpersonal styles. Early symptom change was the best predictor of outcome in CBT-E. Further research is needed to determine whether these results are generalizable to patients with anorexia nervosa.

OBJECTIVE: This study examined whether rapid response to enhanced cognitive behavioral therapy (CBT-E) was associated with superior treatment outcomes in a transdiagnostic sample of patients with an eating disorder. METHOD: Participants were 105 patients with a primary eating disorder diagnosis who received individual CBT-E at a community-based outpatient clinic. Patients completed measures of eating disorder and related pathology at baseline and post-treatment. The Eating Disorder Examination-Questionnaire (EDE-Q) was administered at baseline and again, on average, 4.6 weeks after commencing treatment to assess rapid response to CBT-E. Patients achieving reliable change on the EDE-Q at this point were classified as rapid responders. RESULTS: No baseline differences distinguished rapid and nonrapid responders. Rapid responders had significantly lower scores on EDE-Q global at post-treatment, were more likely to achieve full remission, and required significantly fewer treatment sessions than nonrapid responders. One-quarter of the nonrapid responders went on to achieve full remission. There were no group differences on measures of anxiety and depression symptoms at the end of treatment. DISCUSSION: Early change in treatment is encouraged to achieve the best possible prognosis in CBT-E. Those who did not achieve rapid response still had an overall significant improvement in symptoms from pretreatment to post-treatment, but a lower rate of full remission. Nonrapid responders are an important group of patients to study because they offer researchers an opportunity to improve clinical decision-making and treatment outcomes for patients who are at risk of suboptimal response.

OBJECTIVE: To evaluate the effectiveness of a motivation-focused intervention prior to individual cognitive behavioural eating disorder treatment. METHOD: Enhanced cognitive-behavioural therapy (CBT-E) in its usual form was compared with CBT-E preceded by four sessions of motivation-focused therapy (MFT) (MFT + CBT-E). Participants were adult outpatients seen at a specialist eating disorder clinic in Western Australia, who met criteria for a Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition eating disorder. A sequential trial of CBT-E as usual (n = 43) and MFT + CBT-E (n = 52) was conducted over a 40-month period. RESULTS: The MFT phase was associated with significant increases in readiness to change. There were no significant between-group differences in treatment completion rates, and treatment completers in both conditions reported comparable reductions in eating disorder symptoms over time. CONCLUSION: In this sample, MFT + CBT-E was not associated with superior treatment outcome when compared with CBT-E as usual.

OBJECTIVE: To examine mediators of the relationship between perfectionism and eating disorder (ED) psychopathology in a clinical sample. METHOD: Participants were 201 women with a DSM-IV diagnosed ED consecutively referred to a specialist outpatient treatment clinic. Participants completed measures of perfectionism, ED psychopathology, shape and weight overvaluation, and conditional goal-setting (CGS). RESULTS: Evaluation of a multivariate mediator model using Baron and Kenny's (1986) four-step mediation methodology showed that shape and weight overvaluation and CGS significantly and uniquely mediated the relation between self-oriented perfectionism (SOP) and restraint, eating concern, shape concern, and weight concern. The mediator model furthered the proportion of explained variance in outcomes beyond the direct effects model by 28-49%. DISCUSSION: The findings support the conclusion that the relationship between SOP and ED psychopathology in women with a clinically diagnosed ED is mediated by shape and weight overvaluation and CGS.

The aim of this study was to develop and validate a self-report measure of Conditional Goal Setting (CGS) for use among individuals with eating disorders, the Conditional Goal Setting in Eating Disorders Scale (CGS-EDS). The CGS-EDS assesses the degree to which an individual believes that the achievement of happiness is contingent upon the attainment of body shape and weight goals. Women with a DSM-IV diagnosed eating disorder consecutively referred to a specialist outpatient clinic (N=238) completed the CGS-EDS and self-report measures of theoretically related constructs. Exploratory factor analysis indicated a one-factor solution, which accounted for 65% of the variance. The CGS-EDS correlated positively with theoretically related measures of overvaluation of shape and weight, concern with shape and weight, dichotomous thinking, and depression. The alpha reliability of the scale was .92. The CGS-EDS is a valid and reliable measure of CGS in eating disorders and is relevant to cognitive and behavioral models of maintenance and intervention.
