The Compulsive Exercise Test : confirmatory factor analysis and links with eating psychopathology among women with clinical eating disorders

Background: This study aimed to determine the psychometric properties of the Compulsive Exercise Test (CET) among an adult sample of patients with eating disorders. Method: Three hundred and fifty six patients and 360 non-clinical control women completed the CET and the Eating Disorders Examination questionnaire (EDE-Q). Results: A confirmatory factor analysis revealed that the clinical data showed a moderate fit to the previously published five factor model derived from a community sample (Taranis L, Touyz S, Meyer C, Eur Eat Disord Rev 19:256-268, 2011). The clinical group scored significantly higher than the non-clinical group on four of the five CET subscales, and logistic regression analysis revealed that the CET could successfully discriminate between the two groups. A Receiver Operating Curve analysis revealed that a cut-off score of 15 on the CET resulted in acceptable values of both sensitivity and specificity. Conclusions: The CET appears to have a factor structure that is acceptable for use with an adult sample of patients with eating disorders. It can identify compulsive exercise among patients with eating disorders and a cut-off score of 15 is acceptable as indicating an appropriate cut-off point

Predictors of positive treatment outcome in people with anorexia nervosa treated in a specialized inpatient unit: The role of early response to treatment

o investigate factors which predict positive treatment outcome in inpatients with anorexia nervosa (AN), particularly the role of early treatment response. METHOD: 102 patients entering specialist inpatient treatment were assessed for eating disorder history, psychopathology and motivation to change. Predictive factors assessed were: early treatment response defined as weight increase of at least 0.5-1 kg/week during the first six weeks of treatment; admission BMI; onset age; chronicity; motivation to change; diagnosis; and previous hospitalization for AN. Positive treatment outcome was defined as achieving BMI 17.5 kg/m2 within an individual timeframe. RESULTS: Logistic regression indicated that patients were 18 times more likely to reach positive treatment outcome if they met NICE weight guidelines within the first six weeks of hospitalization. Higher admission BMI was also found to predict positive treatment outcome. DISCUSSION: Higher entry BMI and early weight gain predict positive treatment outcome in individuals receiving specialist AN inpatient treatment

Evaluation of a motivation and psycho-educational guided self help intervention for people with eating disorders (MOPED)

High dropout rates and poor levels of engagement are well documented for patients with eating disorders. Utilising motivational techniques and providing psycho-education have been suggested as ways to reduce treatment disengagement. This study aimed to evaluate the effect of a newly developed motivational and psycho-educational guided self-help intervention (MOPED) for people with eating disorders on engagement and retention in therapy. Patients who received MOPED pre-treatment (n = 79) were compared to a diagnosis matched group of patients receiving treatment as usual (TAU; n = 79). The study found that patients receiving MOPED had a higher engagement rate than those within the TAU group. Specifically, patients in the anorexic spectrum were found to present with both higher rates of engagement and completion of therapy when issued with MOPED in comparison to TAU. Self-help packages using motivational style could be a valuable and cost effective intervention for patients with eating disorders

Treatment outcome of patients with comorbid type 1 diabetes and eating disorders

Background: Co-morbidity between Type 1 Diabetes Mellitus (T1DM) and eating disorders (ED) has been previously described; however the effect of this illness on the outcomes for conventional ED treatments has not been previously investigated. This study aims to compare clinical, psychopathological and personality features between two samples of ED individuals: those with comorbid T1DM and those without (No-DM); and to identify differences in treatment outcomes between the groups. Methods: This study compares treatment outcome, dropouts, ED psychopathology and personality characteristics for 20 individuals with ED and T1DM and 20 ED patients without diabetes, matched for diagnostic and treatment type. Results: The study found higher dropout rates from therapy in individuals with T1DM and worse treatment outcome in spite of having no significant differences in eating disorder psychopathology, although individuals with T1DM report misusing insulin. Conclusions: The low levels of motivation to change, and insulin abuse in T1DM patients, may suggest that treatment for patients with ED and T1DM should consider the individual's personality and role of insulin abuse when determining the appropriate intervention

The clinical effectiveness and cost-effectiveness of a ‘stepping into day treatment’ approach versus inpatient treatment as usual for anorexia nervosa in adult specialist eating disorder services (DAISIES trial): a study protocol of a randomised controlled multi-centre open-label parallel group non-inferiority trial

BACKGROUND: Anorexia nervosa (AN) is a serious and disabling mental disorder with a high disease burden. In a proportion of cases, intensive hospital-based treatments, i.e. inpatient or day patient treatment, are required, with day patient treatment often being used as a 'step-down' treatment after a period of inpatient treatment. Demand for such treatment approaches has seen a sharp rise. Despite this, the relative merits of these approaches for patients, their families, and the NHS and wider society are relatively unknown. This paper describes the rationale for, and protocol of, a two-arm multi-centre open-label parallel group non-inferiority randomised controlled trial, evaluating the effectiveness and cost-effectiveness of these two intensive treatments for adults with severe AN: inpatient treatment as usual and a stepped care day patient approach (the combination of day patient treatment with the option of initial inpatient treatment for medical stabilisation). The main aim of this trial is to establish whether, in adults with severe AN, a stepped care day patient approach is non-inferior to inpatient treatment as usual in relation to improving body mass index (BMI) at 12 months post-randomisation. METHODS: 386 patients with a Diagnostic and Statistical Manual 5th edition diagnosis of severe AN or related disorder, with a BMI of ≤16 kg/m2 and in need of intensive treatment will be randomly allocated to either inpatient treatment as usual or a stepped care day patient approach. Patients in both groups will receive treatment until they reach a healthy weight or get as close to this point as possible. Assessments will be conducted at baseline (prior to randomisation), and at 6 and 12 months post-randomisation, with additional monthly symptom monitoring. The primary outcome will be BMI at the 12-month post-randomisation assessment. Other outcomes will include psychosocial adjustment; treatment motivation, expectations and experiences; cost-effectiveness; and carer burden. DISCUSSION: The results of this study will provide a rigorous evaluation of two intensive treatment approaches which will inform future national and international treatment guidelines and service provision

A randomised controlled trial of the compuLsive Exercise Activity TheraPy (LEAP): a new approach to compulsive exercise in anorexia nervosa

Objective: To compare the efficacy of the compuLsive Exercise Activity theraPy (LEAP) programme integrated with manualised cognitive behavioural therapy for anorexia nervosa (CBT-AN) compared to CBT-AN alone. Method: Seventy-eight adults were randomised to CBT-AN, delivered with or without 8 embedded sessions of LEAP, for a total of 34 individual outpatient sessions. Participants were assessed at baseline, the end of the first phase of CBT-AN (which included LEAP), mid-therapy, end of therapy, and at 3 and 6-months follow-up. Linear mixed effects modelling was used for comparing trajectories over time by group in primary outcomes of pathological exercise cognitions and secondary outcomes of exercise frequency, BMI, eating disorder (ED) symptoms, AN stage of change, anxiety/depression, and health related quality of life. Results: There were significant improvements over time in all outcomes. There were no significant differences between treatment groups in primary outcome measures. Fidelity and end-of- treatment participant satisfaction were satisfactory across both conditions. Discussion: CBT-AN and LEAP added to CBT-AN resulted in improved attitudes and beliefs towards exercise and general improvements in BMI and eating disorder psychopathology in people with AN

Exploring Barriers to South Asian Help-Seeking for Eating Disorders

The file attached to this record is the author's final peer reviewed version. The Publisher's final version can be found by following the DOI link.Purpose Referrals to specialist eating disorder services from the South Asian (SA) community are under-represented, despite research suggesting that disordered eating attitudes and behaviours of SA people are similar to the population in general. The study aimed to identify the reasons for this and sought to inform ways to encourage help-seeking. Design/Methodology/Approach A qualitative methodology was used to investigate barriers to help-seeking for eating disorders among the SA community. A key informant focus group was conducted with clinicians working within the local specialist eating disorder service (participants n=16, 12 female, 4 male). Six focus groups were conducted with members of the SA community in Leicester, UK, (participants n=28, 23 female, 5 male) recruited from a local university, two charities and Children, Young People & Family Centres. Findings A number of themes emerged as possible factors for delaying early access to help: lack of knowledge about eating disorders and their potential seriousness; ideals regarding body shape; family living circumstances, and the role of food in the community. Participants acknowledged stigma among their community associated with mental health issues, including eating disorders, and concerns about confidentiality when approaching services, particularly primary care. Originality/value General practitioners and specialist services need to be aware of the potential barriers to help-seeking for eating disorders as early specialist help is recommended for effective treatment. An educational campaign around eating disorders specifically designed with the SA community in mind may improve awareness, reduce stigma and promote early help-seeking

Can treatment trial samples be representative?

A catchment area-based sample of patients recruited for an eating disorder treatment trial was compared with patients from the same geographical area seen in the 12 months before and after the trial. The three samples were very similar. The research sample was representative of the usual clinic sample from which it had been selected and thus the results could be extrapolated with some confidence to other similar clinical settings. It is concluded that whilst treatment trials, by their very nature, have explicit and implicit inclusion and exclusion criteria with appropriate designs they can be usefully representative

Transdiagnostic Cognitive-Behavioral Therapy for Patients With Eating Disorders: A Two-Site Trial With 60-Week Follow-Up

Objective: The aim of this study was to compare two cognitive-behavioral treatments for outpatients with eating disorders, one focusing solely on eating disorder features and the other a more complex treatment that also addresses mood intolerance, clinical perfectionism, low self-esteem, or interpersonal difficulties. Method: A total of 154 patients who had a DSM-IV eating disorder but were not markedly underweight (body mass index over 17.5), were enrolled in a two-site randomized controlled trial involving 20 weeks of treatment and a 60-week closed period of follow-up. The control condition was an 8-week waiting list period preceding treatment. Outcomes were measured by independent assessors who were blind to treatment condition. Results: Patients in the waiting list control condition exhibited little change in symptom severity, whereas those in the two treatment conditions exhibited substantial and equivalent change, which was well maintained during follow-up. At the 60-week follow-up assessment, 51.3% of the sample had a level of eating disorder features less than one standard deviation above the community mean. Treatment outcome did not depend on eating disorder diagnosis. Patients with marked mood intolerance, clinical perfectionism, low self-esteem, or interpersonal difficulties appeared to respond better to the more complex treatment, with the reverse pattern evident among the remaining patients. Conclusions: These two transdiagnostic treatments appear to be suitable for the majority of outpatients with an eating disorder. The simpler treatment may best be viewed as the default version, with the more complex treatment reserved for patients with marked additional psychopathology of the type targeted by the treatment
