Enhancing motivation for change in treatment-resistant eating disorders

The process of recovery in eating disorder sufferers' own words: an Internet-based study

This exploratory Internet-based study attempts to understand what eating disorder sufferers suggest when they mention the word recovery. All messages (N = 685) posted in a Finnish-language eating disorders discussion group during a 3-month period were analyzed for the contexts of the word recovery using text analysis software and qualitative methods. The discussion group participants' views of recovery changed according to their current stage of change. Mentioning recovery was least likely during precontemplation and relapse. Internet discussion group was seen as helpful in the early stages of change, but as impeding recovery in the last stages. Willpower and ceasing to identify with eating disorders were viewed as essential to recovery. The value of professional help in recovery was viewed as conditional on the eating disorders sufferer's own willingness to change. Internet-based support groups have many potential therapeutic applications. Motivational aspects need to be taken into account in promoting recovery.

Disciplining the feminine: the reproduction of gender contradictions in the mental health care of women with eating disorders

This paper provides insights into the way gendered assumptions operate within health care interventions for women with eating disorders. A multidisciplinary sample of Australian health care workers were interviewed about their approaches to treatment, and discourse analysis was used to uncover the discursive dynamics and power relations characterising their accounts of intervention. The paper demonstrates a contradictory positioning of anorexic patients in relation to autonomy and control within the two common psychiatric interventions of bed rest intervention and psychotherapy. The paper argues that this is based on gendered assumptions about selfhood and femininity in eating disorders that are reproduced in the therapeutic relationship through the operation of a gendered parent-child dynamic, with the health care worker as father or mother, and the anorexic patient as daughter. One of the main effects of this is to re-inscribe rather than challenge the discursive 'double bind' of femininity that has been widely implicated by post-structural feminists in producing eating disorders in the first place. The paper also considers the widely acknowledged problem of resistance to treatment in anorexia as a function of controlling treatments, and discusses psychiatrists' perspectives on addressing this dilemma. Finally, the paper examines the potential of feminist-informed understandings of eating disorders for overcoming the gendered dilemmas inherent within the dominant psycho-medical treatment paradigm.

Virtual Reality in Psychotherapy: Review

Virtual reality (VR) has recently emerged as a potentially effective way to provide general and specialty health care services, and appears poised to enter mainstream psychotherapy delivery. Because VR could be part of the future of clinical psychology, it is critical to all psychotherapists that it be defined broadly. To ensure appropriate development of VR applications, clinicians must have a clear understanding of the opportunities and challenges it will provide in professional practice. This review outlines the current state of clinical research relevant to the development of virtual environments for use in psychotherapy. In particular, the paper focuses its analysis on both actual applications of VR in clinical psychology and how different clinical perspectives can use this approach to improve the process of therapeutic change.

"Becoming the real me": recovering from anorexia nervosa

We investigated the process of recovery from anorexia nervosa using grounded theory. Open-ended interviews conducted with 9 women who had recovered from anorexia nervosa revealed that recovery focused on rediscovery and redefinition of the self and included the following: (1) seeing the dangers, (2) inching out of anorexia, (3) tolerating exposure without anorexia, (4) gaining perspective by changing the anorexia mindset, and (5) discovering and reclaiming self as "good enough." The process of recovery described in this study may provide a useful framework for helping women understand their own process of recovery efforts. The findings also support therapies that foster therapeutic alliance, acknowledge readiness for change, and promote a senses of autonomy.

Assessing quality of life in eating disorder patients

OBJECTIVE

To examine quality of life among subgroups of eating disorder patients.

METHOD

Self-report questionnaires which included two quality of life measures were completed by 87 individuals referred for treatment to the Australian Capital Territory Eating Disorders Day Program. Health-related quality of life, as measured by the Medical Outcomes Study 12-item Short Form Mental Component Summary scale, and subjective quality of life, as measured by subscales of the World Health Organization Brief Quality of Life Assessment Scale (WHOQOL-BREF), were compared among individuals who received the diagnosis of anorexia nervosa purging subtype (n = 15), anorexia nervosa restricting subtype (n = 19), bulimia nervosa (n = 40) and binge eating disorder (n = 10), and among a general population sample of young adult women employed as a control group (n = 495).

RESULTS

Eating disorder patients, when considered together, showed marked impairment in both health-related and subjective quality of life relative to normal control subjects. However, in both domains, restricting anorexia nervosa patients reported significantly better quality of life than other patient groups, after controlling for levels of general psychological distress. Scores on the Social Relationships subscale of the WHOQOL-BREF among individuals in this subgroup were similar to those of normal control subjects.

CONCLUSIONS

Reliance on any one instrument is likely to be misleading in assessing the quality of life of eating disorder patients. Careful consideration needs to be given to the assessment of restricting anorexia nervosa patients in particular.

Readiness to recover in adolescent anorexia nervosa: prediction of hospital admission

OBJECTIVES

To determine if motivation to change in anorexia nervosa during treatment is a predictor of hospitalisation in adolescent patients.

METHOD

The Anorexia Nervosa Stages of Change Questionnaire (ANSOCQ), the Eating Disorders Inventory-2 (EDI-2) and the Beck Depression Inventory (BDI) were administered to a group of 70 anorexia nervosa patients (mean age 15.6 years). They were all receiving treatment at a specialised Eating Disorder Unit and were at different points in the treatment programme. Admission during 6-9 month follow-up was recorded in 63 of these patients who had been admitted to the Unit. The other 7 patients were contacted by phone to determine if they had been hospitalised in another unit during the follow-up period.

RESULTS

Patients who needed hospital admission during follow-up had higher mean scores at first evaluation on some of the EDI-2 scales and on the BDI, lower ANSOCQ scores and were more likely to have been outpatients at first evaluation. In the logistic regression analysis a low ANSOCQ score and being an outpatient at first evaluation were shown to be independent predictors of hospitalisation during follow-up.

CONCLUSIONS

Low motivation to change, depressive symptomatology and some EDI-2 scales are related to the necessity of hospital admission in adolescent patients with anorexia nervosa.

Motivation to change in eating disorder patients: a conceptual clarification on the basis of self-determination theory

OBJECTIVE

The current study critically reviews the different motivational frameworks that are applied in the study of eating disorders and provides a more comprehensive conceptualization of motivation to change on the basis of self-determination theory.

METHOD

The most important conceptualizations of motivation to change among eating disorder patients are identified.

RESULTS

Eating disorder patients' motivation to change has been defined very differently, adding confusion to the field and preventing research from being cumulative. On the basis of self-determination theory we argue (a) that the quality of motivation to change is primarily reflected in the degree of internalization of change rather than by the intrinsic motivation to change; (b) that the internalization of change suggests more than only the change being initiated from within the person (internal motivation) for it requires an acceptance of the personal importance of change; and (c) that, in addition to its quality, the quantity of motivation to change should be considered too.

DISCUSSION

These three conceptual issues are applied to the study of motivational dynamics in eating-disordered patients.

Psychological Treatment of Eating Disorders

Manual-based cognitive behavior therapy (CBT) is presently the most effective treatment of bulimia nervosa. Its efficacy is limited, however. Different strategies for improving upon current manual-based CBT are discussed, including combining CBT with antidepressant medication, integrating CBT with alternative psychological therapies, and expanding the scope and flexibility of manual-based CBT. CBT is underutilized in clinical practice. Dissemination of evidence-based treatment is a priority. Research on anorexia nervosa is minimal. Effective treatments have yet to be developed, although the Maudsley method of family therapy has shown the most promise in the treatment of adolescents. The most commonly seen eating disorders in clinical practice are those classified as "eating disorder not otherwise specified." With the exception of binge eating disorder (BED), however, they have been neglected by researchers. Several psychological therapies have been shown to be effective in treating BED. Controversy exists over whether treatment-specific effects have been identified. Whereas treatments have proved effective in eliminating binge eating and associated eating disorder psychopathology, achieving clinically significant weight loss remains a challenge.

Serotonergic and dopaminergic systems in anorexia nervosa: a role for atypical antipsychotics?

OBJECTIVE

To review serotonergic and dopaminergic system function in anorexia nervosa in terms of potential modulation by atypical antipsychotic medications.

METHOD

A systematic review of clinical, neurobiological and functional neuroimaging findings of serotonergic and dopaminergic system activity in anorexia nervosa was conducted via MEDLINE, PsycINFO and EMBASE psychiatry databases, with a critical review of dysregulation of these systems as therapeutic targets for atypical antipsychotics, in context of evidence regarding the utility and efficacy of these medications in this syndrome.

RESULTS

There is evidence of persistently altered serotonergic and dopaminergic function in anorexia nervosa independent to weight-recovery. Case reports, open-label and single-blinded studies, albeit sparse, suggest that atypical antipsychotics may be beneficial in the management of anorexia nervosa psychopathology beyond weight gain.

CONCLUSIONS

Double-blind placebo controlled studies of atypical antipsychotics in anorexia nervosa with well defined outcome measures are required.

Attitudes towards change and treatment outcome in eating disorders

OBJECTIVE

To investigate the influence of the stage of change on treatment outcome among patients suffering from eating disorders.

METHOD

Sixty-seven women receiving free outpatient treatment for eating disorders initially participated in this study. Their demographic, lifetime and clinical characteristics, eating disorder symptoms and general distress were assesssed at baseline and after one year, together with the results of self-report questionnaire on Attitudes towards Change in Eating Disorders (ACTA).

RESULTS

High scores on the Maintenance subscale were protective for eating psychopathology as measured by the Eating Attitudes Test (EAT-40), Eating Disorders Inventory (EDI-2) and the frequency of purging. Action was predictive of weight changes. Precontemplation and Relapse respectively predicted little change in EAT and the Bulimic Inventory Test Edinburgh (BITE). High Preparation scores were predictive of the level of EDI-2 Interoceptive Awareness, Maturity Fears, and Ascetism.

DISCUSSION

Our results suggest considering the stage of change as a useful outcome predictor.

Difficulties in the assessment of personality traits and disorders in eating-disordered individuals

There are compelling reasons to examine personality variables in the eating disorder (ED) field but many impediments to the collection of useful data. In addition to the conceptual and methodological difficulties associated with personality assessment in the general case, the EDs present a number of special problems. These include patients' young age at onset and evaluation, the "state" effects of semi-starvation and chaotic eating, denial and distortion in self-report, the instability of ED subtypes, and the intrusion of eating and weight concerns into a wide range of apparently unrelated domains. Although there is substantial support for the clinical view that personality variables are linked to anorexia nervosa (AN) and bulimia nervosa (BN), the identification of stable traits and Axis II disorders in individual patients should be deferred until after the initial phase of treatment.

Drop outs from in-patient treatment of anorexia nervosa

OBJECTIVE

Aim of the study was to identify patient characteristics that distinguish drop outs and completers from in-patient treatment for anorexia nervosa.

METHOD

A total of 133 consecutively admitted in-patients with anorexia nervosa (age range 16-50 years; 92.5% women) were analysed using sociodemographic variables as well as measures of psychopathology (SCL-90-R, EDI-2) and interpersonal difficulties (IIP-C). Patients were treated in a multimodal treatment setting, combining cognitive-behavioural and psychodynamic components.

RESULTS

Patients, who reported fewer symptoms, were hospitalized before and had a comorbid depression stayed more often in psychotherapy. Patients dropping out of treatment (31.6%) showed a trend to higher levels of maturity fears. Subtype, age, duration of illness, comorbid personality disorders or previous drop outs were not predictive of dropping out.

CONCLUSION

Addressing the high ambivalence and maturity fears of anorexic patients should be an essential issue in psychotherapy with this patient group.

The development of the P-CAN, a measure to operationalize the pros and cons of anorexia nervosa

OBJECTIVE

Research has suggested that a fundamental aspect of anorexia nervosa (AN) is its egosyntonic nature, the fact that it is often valued by individuals with the disorder. The current study describes the development of the P-CAN, a quantitative measure of both positive (valued) and negative aspects of AN.

METHOD

Items were derived from a previous qualitative study (Serpell, Treasure, Teasdale, & Sullivan. 1999. International Journal of Eating Disorders, 25, 177-186). Data from 233 women with AN were subjected to a principal components analysis.

RESULTS

Ten subscales were identified, six describing the pros of AN and four describing the cons of the illness.

DISCUSSION

The P-CAN shows good psychometric properties and should prove a useful tool for the measurement of attitudes towards AN, as well as offer insights into the maintenance of the disorder.

Eating disorders: clinical features and pathophysiology

Anorexia nervosa (AN) and bulimia nervosa (BN) are disorders of eating and weight-related behavior that together afflict some 1-3% of women in the United States. One of the remarkable features about each of the eating disorders is how persistent the disordered eating behavior becomes once it has begun. Substantial psychological, social, and physiological disturbances are associated with eating disorders, and it has been very difficult to disentangle those factors that may result from the disturbed behavior from the factors that may have predisposed individuals to, or precipitated the development of, the disorder. This article will briefly review the definitions, phenomenology, and identified risk factors for development of each of the major eating disorders. Pathophysiology will be discussed, with a particular focus on candidate factors that might sustain disordered eating behavior, as informed by clinical and basic science research. Future research directions will be suggested.

Australian and New Zealand clinical practice guidelines for the treatment of anorexia nervosa

BACKGROUND

The Royal Australian and New Zealand College of Psychiatrists is co-ordinating the development of clinical practice guidelines (CPGs) in psychiatry, funded under the National Mental Health Strategy (Australia) and the New Zealand Ministry of Health. This CPG covers anorexia nervosa (AN).

METHOD

The CGP team consulted with scientists, clinicians, carers and consumer groups in meetings of over 200 participants and conducted a systematic review of meta-analyses, randomized controlled trials and other studies.

TREATMENT RECOMMENDATIONS

It is extremely difficult to draw general conclusions about the efficacy of specific treatment options for AN. There are few controlled clinical trials and their quality is generally poor. These guidelines necessarily rely largely upon expert opinion and uncontrolled trials. A multidimensional approach is recommended. Medical manifestations of the illness need to be addressed and any physical harm halted and reversed. Weight restoration is essential in treatment, but insufficient evidence is available for any single approach. A lenient approach is likely to be more acceptable to patients than a punitive one and less likely to impair self-esteem. Dealing with the psychiatric problems is not simple and much controversy remains. For patients with less severe AN who do not require in-patient treatment, out-patient or day-patient treatment may be suitable, but this decision will depend on availability of such services. Family therapy is a valuable part of treatment, particularly for children and adolescents, but no particular approach emerges as superior to any other. Dietary advice should be included in all treatment programs. Cognitive behaviour therapy or other psychotherapies are likely to be helpful. Antidepressants have a role in patients with depressive symptoms and olanzapine may be useful in attenuating hyperactivity.

The transtheoretical model and motivational interviewing in the treatment of eating and weight disorders

The transtheoretical stages of change model suffers from conceptual and empirical limitations, including problems of stage definition, measurement, and discreteness. Sequential transition across stages has not been established. The model lacks strong predictive utility, and there is little evidence that therapeutic interventions must be matched to stage to facilitate change. Initial tests applying the model to weight and eating disorders have been negative. Although the model is frequently associated with motivational interviewing (MI), no theory links the two. MI should be evaluated independently as a treatment for weight and eating disorders, to be used either alone or prior to treatments not explicitly addressing motivation. The conceptual compatibility and procedural overlap between cognitive behavioral therapy (CBT) and MI are analyzed.

Application of Prochaska's transtheoretical model of change to patients with eating disorders

OBJECTIVE

Although eating disorders cause severe somatic and psychological sequelae, a majority of affected patients are not motivated for treatment. The aim of this study was to assess stages of change in patients with eating disorders and to analyze their correlations with clinical characteristics and treatment processes using Prochaska's transtheoretical model of change.

METHODS

A consecutive sample (N=88) including outpatients suffering from anorexia (n=29), bulimia (n=32), and eating disorders not otherwise specified (n=27) was recruited from an eating disorders clinic with a low-threshold access. The patients' readiness to change their eating behavior was assessed by a self-rating scale (URICA), and a score for each participant on each subscale (precontemplation, contemplation, action) was derived from the scale. Patients were introduced to a set of eight treatment processes over the course of four treatment sessions. During the four sessions, therapists rated whether or not patients appeared to be using each of the treatment processes.

RESULTS

While diagnostic subtype, age, illness duration, and previous treatments were not associated with motivational stages, self-referral was positively correlated to treatment motivation. Emotional involvement, specific behavioral change processes, and beginning a continuing treatment were correlated with more advanced stages of change.

CONCLUSION

This study supports the notion of the stages of change as an independent dimension that is relevant for the treatment of eating disorders. The lack of impact of previous, presumably nonspecific treatments on the stages of change underlines the importance to assess and to improve specifically patients' motivation. Therapeutic work towards the mobilisation of emotions with regard to their eating problem as a means to improve readiness to change should be examined in future studies.

Beliefs of women concerning causes and risk factors for bulimia nervosa

OBJECTIVE

To examine the beliefs of women concerning causes and risk factors for eating-disordered behaviour.

METHOD

Face-to-face interviews were conducted with a community sample of 208 women aged 18-45 years. Respondents were presented with a vignette describing a fictional person meeting diagnostic criteria for bulimia nervosa (BN) and were asked to indicate whether each of several factors was 'very likely', 'likely' or 'not likely' to be a cause of the problem described, which factor was most likely to be a cause, and whether particular subgroups of people would be 'more likely', 'less likely' or 'equally likely' to have or develop the problem described.

RESULTS

'Having low self-esteem' was considered very likely to be a cause of BN by 75.0% of respondents, and the most likely cause by 40.5% of respondents. Other factors perceived as significant were 'problems from childhood', 'portrayal of women in the media', 'being overweight as a child or adolescent' and 'day-to-day problems', while genetic factors and pre-existing psychological problems were perceived to be of minor significance. Most respondents believed that women aged under 25 years were at greatest risk of having or developing BN.

CONCLUSIONS

Women's beliefs concerning causes and risk factors for BN are generally consistent with empirical evidence. However, information concerning the increased risk associated with pre-existing anxiety and affective disorders might usefully be included in prevention programs. Systematic investigation of the benefits of addressing individuals' beliefs concerning risk factors for eating disorders - as opposed to risk factors per se - would be of interest.

Report of the National Institutes of Health workshop on overcoming barriers to treatment research in anorexia nervosa

OBJECTIVE

Anorexia nervosa (AN) is associated with serious medical morbidity and has the highest mortality rate of all psychiatric disorders. The National Institutes of Health (NIH) Workshop on Overcoming Barriers to Treatment Research in Anorexia Nervosa convened on September 26-27, 2002 to address the dearth of treatment research in this area. The goals of this workshop were to discuss the stages of illness and illness severity, pharmacologic interventions, psychological interventions, and methodologic considerations.

METHOD

The program consisted of a series of brief presentations by moderators, each followed by a discussion of the topic by workshop participants, facilitated by the session chair.

RESULTS

This report summarizes the major discussions of these sessions and concludes with a set of recommendations related to the development of treatment research in AN based on these findings.

DISCUSSION

It is crucial that treatment research in this area be prioritized.

Motivational interviewing in health settings: a review

There is evidence that patient-centred approaches to health care consultations may have better outcomes than traditional advice giving, especially when lifestyle change is involved. Motivational interviewing (MI) is a patient-centred approach that is gathering increased interest in health settings. It provides a way of working with patients who may not seem ready to make the behaviour changes that are considered necessary by the health practitioner. The current paper provides an overview of MI, with particular reference to its application to health problems.

The VEPSY UPDATED Project: clinical rationale and technical approach

More than 10 years ago, Tart (1990) described virtual reality (VR) as a technological model of consciousness offering intriguing possibilities for developing diagnostic, inductive, psychotherapeutic, and training techniques that can extend and supplement current ones. To exploit and understand this potential is the overall goal of the "Telemedicine and Portable Virtual Environment in Clinical Psychology"--VEPSY UPDATED--a European Community-funded research project (IST-2000-25323, www.cybertherapy.info). Particularly, its specific goal is the development of different PC-based virtual reality modules to be used in clinical assessment and treatment of social phobia, panic disorders, male sexual disorders, obesity, and eating disorders. The paper describes the clinical and technical rationale behind the clinical applications developed by the project. Moreover, the paper focuses its analysis on the possible role of VR in clinical psychology and how it can be used for therapeutic change.

Psychotherapy for bulimia nervosa and binging

BACKGROUND

Bulimia nervosa and related syndromes such as binge eating disorder are common in young Western women. A specific manual-based form of cognitive behaviour therapy (CBT) has been developed for the treatment of bulimia nervosa (CBT-BN). Other psychotherapies, some from a different theoretical framework, and some modifications of CBT are also used.

OBJECTIVES

To evaluate the efficacy of CBT and CBT-BN and compare them with other psychotherapies in the treatment of adults with bulimia nervosa or related syndromes of recurrent binge eating.

SEARCH STRATEGY

A handsearch of The International Journal of Eating Disorders since its first issue; database searches of MEDLINE, EXTRAMED, EMBASE, PsycInfo, CURRENT CONTENTS, LILACS, SCISEARCH, CENTRAL and the The Cochrane Collaboration Depression, Anxiety & Neurosis Controlled Trials Register; citation list searching and personal approaches to authors were used.

SELECTION CRITERIA

All studies that have tested any form of psychotherapy for adults with non-purging bulimia nervosa, binge eating disorder and/or other types of eating disorders of a bulimic type (eating disorder, not otherwise specified, or EDNOS), and which applied a randomised controlled and standardised outcome methodology.

DATA COLLECTION AND ANALYSIS

Data were analysed using the Review Manager software program. Relative risks were calculated for binary outcome data. Standardized mean differences were calculated for continuous variable outcome data. A fixed effects model was used to analyse the data. Sensitivity analyses of a number of measures of trial quality were conducted. Data were not reported in such a way to permit subgroup analyses, but the effects of treatment on depressive symptoms, psychosocial and/or interpersonal functioning, general psychiatric symptoms and weight were examined where possible. Funnel plots were drawn to investigate the presence of publication bias.

MAIN RESULTS

The review supported the efficacy of cognitive-behavioural psychotherapy (CBT) and particularly CBT-BN in the treatment of people with bulimia nervosa and also (but less strongly due to the small number of trials) related eating disorder syndromes. CBT was also shown to be effective in group settings. Other psychotherapies were also efficacious, particularly interpersonal psychotherapy in the longer-term. Self-help approaches that used highly structured CBT treatment manuals, were promising albeit with more modest results generally, and their evaluation in bulimia nervosa merits further research. Exposure and Response Prevention did not appear to enhance the efficacy of CBT.Psychotherapy alone is unlikely to reduce or change body weight in people with bulimia nervosa or similar eating disorders.

REVIEWERS' CONCLUSIONS

There is a small body of evidence for the efficacy of cognitive-behaviour therapy in bulimia nervosa and similar syndromes, but the quality of trials is very variable and sample sizes are often small. More trials of CBT are needed, particularly for binge eating disorder and other EDNOS syndromes. Trials evaluating other psychotherapies and less intensive psychotherapies should also be conducted.

Management of child and adolescent eating disorders: the current evidence base and future directions

Although eating disorders in children and adolescents remain a serious cause of morbidity and mortality, the evidence base for effective interventions is surprisingly weak. The adult literature is growing steadily, but this is mainly with regard to psychological therapies for bulimia nervosa and to some extent in the field of pharmacotherapy. This review summarises the recent research literature covering management in three areas, namely physical management, psychological therapies, and service issues, and identifies prognostic variables. Findings from the adult literature are presented where there is good reason to believe that these might be applied to younger patients. Evidence-based good practice recommendations from published clinical guidelines are also discussed. Suggestions for future research are made, focusing on 1) the need for trials of psychological therapies in anorexia nervosa, 2) applications of evidence-based treatments for adult bulimia nervosa to the treatment of adolescents, and 3) clarification of the benefits and costs of different service models.

Emerging psychotherapies for eating disorders

Eating disorders are serious illnesses associated with significant medical and psychological sequelae and, in the case of anorexia nervosa, significant mortality. Established psychotherapies such as cognitive-behavioral therapy and interpersonal therapy are effective for many patients with eating disorders. However, these treatments fail to yield full long-term remission in a substantial number of patients. There is a need for novel psychotherapeutic approaches for patients with eating disorders. The authors review three promising new treatment approaches in the field of eating disorders. Motivational enhancement therapy is based on established motivational principles for treating patients with addictive disorders and has been adapted as an early component of treatment for patients with anorexia nervosa and bulimia nervosa. Dialectical behavioral therapy was initially developed for the treatment of borderline personality disorder and has been successfully applied to patients with binge eating. A novel form of family therapy, the Maudsley family treatment for adolescents with anorexia nervosa, has been newly manualized, and studies using this treatment are ongoing. For each treatment, the authors review the theory and techniques of treatment and then go on to review existing data on treatment efficacy.

Eating disorders in children and adolescents

Anorexia nervosa and bulimia nervosa are common disorders in the pediatric population. This article is designed to help the clinician develop a detailed understanding of these disorders as they affect children and adolescents. The etiology, diagnosis, complications, and treatment of these eating disorders are discussed. The special circumstances of diabetes mellitus, athletics, and the interface with the obese patient also are covered. The need to correctly identify a patient with the disorder, perform the appropriate testing, and organize the most appropriate treatment is required from virtually every primary care practitioner.

The interpretation of symptoms of severe dietary restraint

A recent cognitive-behavioural theory of eating disorders proposes that people with eating disorders interpret symptoms of dietary restraint in terms of control. The primary aim of the present study was to test this hypothesis. A second aim was to test the hypothesis derived from clinical observation that people with eating disorders view these symptoms positively. Forty-four participants meeting DSM-IV criteria for a clinical eating disorder and 80 control participants with no history of an eating disorder completed an ambiguous scenario paradigm and self-report measures of eating disorder features and depression. Patients with eating disorders were significantly more likely to interpret symptoms of dietary control in terms of control, providing support for the cognitive-behavioural theory. There was only partial support for the second hypothesis. The implications for the new cognitive-behavioural theory and therapy are discussed.

The use of the Pros and Cons of Anorexia Nervosa (P-CAN) Scale with children and adolescents

OBJECTIVE

The Pros and Cons of Anorexia Nervosa (P-CAN) Scale was developed out of a previous qualitative study [Int J Eat Disord 25 (1999) 177] in which the positive and negative aspects of anorexia nervosa (AN) were elicited from individuals with AN. Principal components analysis was then used in an adult sample to reduce the number of items and to derive empirically and theoretically based subscales [Serpell et al., submitted]. The aim of the current study was to validate the P-CAN in children and adolescents with AN and compare the pros and cons of young people with AN with those of adults.

METHODS

Forty-eight young people with AN completed the P-CAN and the Eating Disorders Examination, a semistructured interview used to aid in the diagnosis of eating disorders.

RESULTS

Validity in younger patients appeared to be good. Children and adolescents showed both similarities and differences from adults tested in a previous study.

CONCLUSIONS

The measure is the first to measure attitudes of children and adolescents with AN towards their illness and may prove a useful tool for the measurement of attitudes towards AN in both clinical and research settings.

Eating disorders

Eating disorders are an important cause of physical and psychosocial morbidity in adolescent girls and young adult women. They are much less frequent in men. Eating disorders are divided into three diagnostic categories: anorexia nervosa, bulimia nervosa, and the atypical eating disorders. However, the disorders have many features in common and patients frequently move between them, so for the purposes of this Seminar we have adopted a transdiagnostic perspective. The cause of eating disorders is complex and badly understood. There is a genetic predisposition, and certain specific environmental risk factors have been implicated. Research into treatment has focused on bulimia nervosa, and evidence-based management of this disorder is possible. A specific form of cognitive behaviour therapy is the most effective treatment, although few patients seem to receive it in practice. Treatment of anorexia nervosa and atypical eating disorders has received remarkably little research attention.

Anguish and Despair in Adolescents with Eating Disorders

Summary: Adolescents struggling against anorexia nervosa or bulimia nervosa often experience self-punishing thoughts and behaviors, including self-mutilation, and suicidal ideation and attempts. These arise out of the profound anguish and despair frequently experienced by these young people. This paper outlines four particularly salient clinical themes underlying this despair that have significant implications for treatment. A practice perspective is discussed which emphasizes empathic listening and the development of a strong therapeutic alliance with the adolescent. Treatment recommendations draw from narrative theory and practice, and from feminist perspectives. The paper also draws on cognitive therapy and on recent developments in the areas of spirituality and motivational enhancement. Involving the distressed adolescent's family is also addressed.

Individual psychotherapy in the outpatient treatment of adults with anorexia nervosa

BACKGROUND

Anorexia nervosa is a disorder of high morbidity and significant mortality. It is commonest in young adult women, in whom the incidence may be increasing. The focus of treatment has moved to an outpatient setting and a number of differing psychotherapies are presently used in treatment.

OBJECTIVES

The aim of the present review was to evaluate the evidence from randomised controlled trials for the efficacy of outpatient psychotherapies used in the treatment of older adolescents and adults with anorexia nervosa

SEARCH STRATEGY

The strategy comprised database searches of MEDLINE, EXTRAMED, EMBASE,PSYCLIT, CURRENT CONTENTS, Cochrane Collaboration Controlled Trials Register and the Depression and Anxiety Neuroses Cochrane Group (CCDAN), a hand-search of The International Journal of Eating Disorders, and he reference lists of all papers selected. Personal letters were sent to identified notable researchers published in the area, requesting information on trials that are unpublished or in progress.

SELECTION CRITERIA

All randomised controlled trials of adult individual outpatient therapy for anorexia nervosa as defined by the DSM-IV or similar international criterion. Quality ratings were made according to the CCDAN criteria and in addition, whether the trial had examined treatment integrity.

DATA COLLECTION AND ANALYSIS

A range of outcome variables were selected, including physical state, severity of eating disorder attitudes and beliefs, interpersonal function, and general psychiatric symptom severity. Continuous outcome data comparisons were made with the standardized mean difference statistic, and binary outcome comparisons made with the relative risk statistic. Reliability of data extraction and quality ratings were made with the kappa statistic. Sensitivity analyses to evaluate the effects of trial quality and subgroup analyses to explore specific questions of treatment effects from different settings, frequency and duration of therapies were planned.

MAIN RESULTS

Six small trials only, two of which included children or adolescents, were identified from the search and aggregation of data was not possible. Bias was possible due particularly to lack of blinding of outcome assessments. The results in two trials suggested that 'treatment as usual' or similar may be less efficacious than a specific psychotherapy. No specific treatment was consistently superior to any other specific approach. Dietary advice as a control arm had a 100% non-completion rate in one trial.

REVIEWER'S CONCLUSIONS

No specific approach can be recommended from this review. It is unclear why 'treatment as usual' performed so poorly or why dietary advice alone appeared so unacceptable as the reasons for non-completion were not reported. There is an urgent need for large well-designed trials in his area.

"Knowing one's self" anorexic: implications for therapeutic practice

OBJECTIVE

Recent postmodernist studies of anorexia nervosa (AN) challenge current clinical understandings and therapies by illuminating not what AN is but how what it is known to be by clinicians helps construct the disorder and therapy for it. This study points to the equal if not greater importance of how patients know AN.

METHODS

Using a deconstructive approach, the discourses of a group of women diagnosed with severe AN were analyzed to reveal radically different versions of "knowing one's self" anorexic.

RESULTS

These versions of "self" have strategically different implications for, and meanings of, any therapeutic endeavour.

DISCUSSION

Postmodernist approaches point to the need for social reconstruction of lay and community understandings of AN. They also have implications at the level of individual therapy, and could be deployed with patients to establish individual but authentic bases for therapy.

Marital status and eating disorders: an analysis of its relevance

OBJECTIVES

This study attempts to understand the clinical impact of marital status on the psychopathology and symptomatology of anorexia (AN) and bulimia nervosa (BN) patients.

METHOD

Eating disorder (ED) patients (n=332, 198 BN and 134 AN) consecutively admitted to our unit participated in the study. All subjects met DSM-IV criteria for those pathologies and were female. Our sample was divided retrospectively into three subgroups based on their marital status. For the assessment, commonly applied questionnaires in the field of ED were used [Eating Attitudes Test (EAT-40), Eating Disorder Inventory (EDI), Bulimic Investigatory Test Edinburgh (BITE), Body Shape Questionnaire (BSQ), Beck Depression Inventory (BDI) and Social Avoidance and Distress Scale (SAD)].

RESULTS

2 x 3 (Diagnostic x Marital status) ANOVA and ANCOVA (with age as covariance) designs were applied in the current study. Our results suggested that ED patients who lived with a partner were significantly different with respect to the other ED patients in the following variables: higher age (P<.0001), higher motivation for change (P<.004), perfectionism (P<.03) and purging behavior (P<.04).

DISCUSSION

The main finding in this study is that ED patients who live with a partner are those who presented greater eating symptomatology and psychopathology but even higher motivation for change. Interpersonal functionality has to be considered in the development and maintenance of ED.

Using the PAI with an eating disordered population: scale characteristics, factor structure, and differences among diagnostic groups

Psychometric properties of the Personality Assessment Inventory (PAI; Morey 1991) within an eating disordered sample seeking treatment (N = 238) and differences among eating disorder diagnostic groups on the PAI were examined. The PAI showed acceptable alpha coefficients, item-total correlations, and interitem correlations. The factor structure was similar to that reported by Morey (1991), with the addition of another factor related to interpersonal coolness and distance. Those with binge eating disorder (BED) reported fewer problems and less distress in general compared to other eating disordered groups. The BED and bulimia nervosa groups were different from the anorexia nervosa groups in frequency of matching on two PAI clusters. Use of the PAI with an eating disordered population and its utility in understanding eating disorder diagnostic groups is supported.

The emergence and treatment of anorexia and bulimia nervosa. A comprehensive and practical model

The objective was to propose and describe a new bio-psycho-social model of emergence and maintenance of anorexia nervosa and bulimia nervosa, and demonstrate its application to treatment. An original model, based on literature review and our own clinical experience, was created. Therapeutic guidelines were derived from the theoretical model and applied in the treatment of 97 anorexia and bulimia nervosa patients presented at the eating disorders unit at Kaplan Hospital in Israel over 18 months. A team comprising a pediatrician, a child psychiatrist, a dietician, and trained nurses collaborated in a comprehensive systemic therapeutic approach involving parents, schools, and community agents.

RESULTS

Ninety-one girls and six boys were treated in the eating disorder unit (55 had AN, 29 had BN and 13 had EDNOS). Thirty-seven patients were hospitalized and sixty were treated in the outpatient clinic. Mean hospitalization time of the first five patients was 108 days. Mean hospitalization time of the remaining 32 patients was reduced to 32 days. The mean number of outpatient clinic interventions was 12. At the one-year follow up, 74 patients were doing well in all respects. Fourteen patients still needed a lot of supervision in eating. Five are still hospitalized and four were lost to follow up.

CONCLUSIONS

The proposed model proves to be more than just another theory in that it is successfully applied in treatment. Short systemic therapy is very effective. The longer the delay in drastic, aggressive treatment, the worse the prognosis. Extended hospitalization periods worsen the prognosis. Weakness of the parental unit is a strong indication for inpatient care. The longer the experience in treating eating disorders, the shorter the hospitalization and number of interventions.

Bulimia nervosa: friend or foe? The pros and cons of bulimia nervosa

OBJECTIVE

The aim of the current study was to use a qualitative approach to investigate the attitude of people with bulimia nervosa (BN) to their illness.

METHOD

Patients with BN were asked to write two letters to their bulimia, one addressing it as a friend and the other addressing it as an enemy. We used a coding scheme to classify themes in letters of people with anorexia nervosa (AN) to group together themes expressed by those with BN. We revised the coding scheme to include themes that were not present in the letters of people with AN.

RESULTS

There were both similarities and differences in the themes described by AN and BN patients. Two positive themes (BN allowing the individuals to eat and not get fat and BN as a way of dealing with boredom) and two negative themes (shame or low self-esteem resulting from BN and obsessive thoughts of weight and shape) were added to the coding scheme to account for these differences.

DISCUSSION

The positive and negative aspects of BN differ in some important ways from those expressed by patients with AN. The meaning of these differences is discussed with reference to the wider symptom pattern of BN compared with AN and their importance with reference to motivation for change is outlined.

Virtual-reality-based multidimensional therapy for the treatment of body image disturbances in binge eating disorders: a preliminary controlled study

The main goal of this paper is to preliminarily evaluate the efficacy of a virtual-reality (VR)-based multidimensional approach in the treatment of body image attitudes and related constructs. The female binge eating disorder (BED) patients (n = 20), involved in a residential weight control treatment including low-calorie diet (1200 cal/day) and physical training, were randomly assigned either to the multidimensional VR treatment or to psychonutritional groups based on the cognitive-behavior approach. Patients were administered a battery of outcome measures assessing eating disorders symptomathology, attitudes toward food, body dissatisfaction, level of anxiety, motivation for change, level of assertiveness, and general psychiatric symptoms. In the short term, the VR treatment was more effective than the traditional cognitive-behavioral psychonutritional groups in improving the overall psychological state of the patients. In particular, the therapy was more effective in improving body satisfaction, self-efficacy, and motivation for change. No significant differences were found in the reduction of the binge eating behavior. The possibility of inducing a significant change in body image and its associated behaviors using a VR-based short-term therapy can be useful to improve the body satisfaction in traditional weight reduction programs. However, given the nature of this research that does not include a followup study, the obtained results are preliminary only.
