Does personalized feedback improve the outcome of cognitive-behavioural guided self-care in bulimia nervosa? A preliminary randomized controlled trial.

OBJECTIVES: Feedback has long been a part of psychosocial and health behaviour interventions and with the advent of computerised assessment and treatment tools, is gaining greater importance. The aim of the present study was to evaluate the addition of personalized feedback to a guided cognitive-behavioural (CBT) self-help programme for patients with bulimia nervosa. DESIGN: Randomised-controlled trial. METHOD: 61 patients with DSM-IV bulimia nervosa or eating disorder not otherwise specified (EDNOS) were randomly allocated to receive 14 sessions of cognitive behavioural guided self-care with or without added personalised feedback on current physical and psychological status, risk and problems, and variables facilitating or hindering change. Feedback to patients was delivered in a number of ways: (a) personalised letters after assessment and at the end of treatment, (b) a specially designed feedback form administered half-way through treatment, (c) computerised feedback about bulimic and other symptoms, such as anxiety, depression and interpersonal functioning repeated at intervals throughout treatment and follow-up. RESULTS: Outcome was assessed using patient-rated measures of bulimic symptoms at the end of treatment and at 6-month follow-up. The data were analysed using maximum likelihood methods of assess group differences at the follow-up. Added feedback did not have an effect on take-up or drop-out from treatment. However, it improved outcome by reducing self-induced vomiting and dietary restriction more effectively. CONCLUSIONS: The findings lend support to the notion that the addition of repeated personalised feedback improves outcome from guided CBT self-help treatment and deserves further study.

A neurodevelopmental model for anorexia nervosa.

This paper integrates genetic and biological data on aetiological risk for anorexia nervosa (AN) with cognitive and psychosocial explanatory models. We have reviewed clinical and basic science data from each of these domains and then used a developmental perspective to formulate a multifactorial threshold model. By positioning interpersonal stress as a central component of this model, psychological, social and biological conceptualisations of AN can be used to generate a data driven, neurodevelopmental hypothesis for the aetiology of this complex disorder.

Social comparison and submissive behaviour in eating disorder patients.

Animal analogues of anorexia nervosa suggest that submissive behaviour and social defeat may be implicated in the onset of wasting diseases. Data from human sufferers of anorexia nervosa and bulimia nervosa are also consistent with the presence of submissive behaviours and perceived low social rank (e.g. low self-esteem, helplessness, and feelings of shame). A total of 101 patients with eating disorders completed the Submissive Behaviour Scale and the Social Comparison Rating Scale, and their responses were compared with 101 age- and sex-matched student controls. Patients with eating disorders reported significantly higher levels of submissive behaviour and a more unfavourable social comparison than did student controls. Furthermore, levels of submissive behaviour and unfavourable social comparison were significantly related to severity of eating disorder symptoms, even after taking account of depressive symptoms and other psychopathology. These preliminary results suggest that ranking theory may have some application to eating disorders. Further research is required to determine whether rank plays a specific role in eating disorders (beyond the increased rates of depression which also occur in eating disorders) and, if so, what is its precise role.

An exploration of eating disorders in a Georgian sample.

BACKGROUND: There is debate as to whether eating disorders may be culture-bound. However, accumulating evidence suggests that eating disorders may be found outside of the West, although the precise form of the eating disorder may differ. AIMS: There were two aims of this study: (1) to translate and establish the psychometric properties of standard questionnaires to measure eating pathology in a Georgian sample; (2) to use these measures to determine whether cases of eating disorders exist in Georgia. METHODS: We held focus groups of various health professionals to establish how eating disorders present in Georgia and to identify groups perceived to be at high risk of having an eating disorder. We obtained translated versions of a number of standardized questionnaires (measuring eating and general psychopathology) from 245 women from these identified high risk groups and a subsample were given a structured clinical interview. RESULTS: We estimated from the responses to the questionnaires, that as many as 5% may have clinically significant bulimia nervosa, 7% fell in the weight range for anorexia nervosa with a further 7% in the weight range for obesity. We interviewed a sample of the high scoring group which confirmed the presence of clinically significant eating pathology in the majority of those identified as possible cases. CONCLUSIONS: The results of this study suggest there may be women in Georgia with significant eating problems.
