ABSTRACT The aim of this study was to examine the effectiveness of Enhanced Cognitive Behaviour Therapy (CBT-E) for eating disorders in an open trial for adults with the full range of eating disorders found in the community. The only previously published trial of CBT-E for eating disorders was a randomised controlled trial (RCT) conducted in the U.K. for patients with a BMI ≥ 17.5. The current study represents the first published trial of CBT-E to include patients with a BMI<17.5. The study involved 125 patients referred to a public outpatient clinic in Perth, Western Australia. Patients attended, on average, 20-40 individual sessions with a clinical psychologist. Of those who entered the trial, 53% completed treatment. Longer waiting time for treatment was significantly associated with drop out. By the end of treatment full remission (cessation of all key eating disorder behaviours, BMI ≥ 18.5 kg/m(2), not meeting DSM-IV criteria for an eating disorder) or partial remission (meeting at least 2 these criteria) was achieved by two thirds of the patients who completed treatment and 40% of the total sample. The results compared favourably to those reported in the previous RCT of CBT-E, with one exception being the higher drop-out rate in the current study. Overall, the findings indicated that CBT-E results in significant improvements, in both eating and more general psychopathology, in patients with all eating disorders attending an outpatient clinic.

    ABSTRACT: The research-practice gap is of concern in the treatment of eating disorders. Despite the existence of empirically supported treatments, few receive them. The barriers to wider dissemination and implementation of evidence-based treatment include clinician attitudes towards such treatments and the lack of sufficient numbers of suitably trained therapists to provide treatment. In this review we discuss these barriers in the context of the wider issue of the dissemination and implementation of psychological treatments and review the research with regard to the treatment of eating disorders. Particular emphasis is placed on examining recent efforts to expand the availability and reach of treatments by making treatment delivery and training more scalable. We highlight promising developments and areas where further research is needed.

    ABSTRACT: Background: Enhanced Cognitive Behaviour Therapy (CBT-E) (Fairburn, Cooper and Shafran, 2003) was developed as a treatment approach for eating disorders focusing on both core psychopathology and additional maintenance mechanisms. Aims: To evaluate treatment outcomes associated with CBT-E in a NHS Eating Disorders Service for adults with bulimia and atypical eating disorders and to make comparisons with a previously published randomized controlled trial (Fairburn et al., 2009) and "real world" evaluation (Byrne, Fursland, Allen and Watson, 2011). Method: Participants were referred to the eating disorder service between 2002 and 2011. They were aged between 18-65 years, registered with a General Practitioner within the catchment area, and had experienced symptoms fulfilling criteria for BN or EDNOS for a minimum of 6 months. Results: CBT-E was commenced by 272 patients, with 135 completing treatment. Overall, treatment was associated with significant improvements in eating disorder and associated psychopathology, for both treatment completers and the intention to treat sample. Conclusions: Findings support dissemination of CBT-E in this context, with significant improvements in eating disorder psychopathology. Improvements to global EDE-Q scores were higher for treatment completers and lower for the intention to treat sample, compared to previous studies (Fairburn et al., 2009; Byrne et al., 2011). Level of attrition was found at 40.8% and non-completion of treatment was associated with higher levels of anxiety. Potential explanations for these findings are discussed.

    ABSTRACT: Cognitive-behavioural therapy (CBT) can be effective for anorexia nervosa. However, there is evidence that the delivery of treatments for the eating disorders is inconsistent. This study examined evidence that clinician characteristics and practice can influence the effective implementation of CBT. The participants were 100 qualified clinicians who routinely offered outpatient CBT to adults with anorexia nervosa. They completed a survey of their demographic characteristics, level of anxiety, clinical practice in CBT for anorexia nervosa, and beliefs about the relationship between weight gain and therapeutic alliance in the early part of such treatment. Greater reported levels of weight gain were associated with the use of manuals, early focus on weight gain as a target, structured eating, and a belief that weight gain precedes a good working alliance. Clinician anxiety and early focus on the therapeutic alliance rather than structured eating were associated with poorer outcomes. These conclusions need to be tested within clinical and research settings. However, they suggest that clinicians should be encouraged to use manual-based approaches when treating anorexia nervosa using CBT, as focusing on techniques might result in the best possible outcome in this early part of treatment.
