Mental health impairment associated with eating-disorder features in a community sample of women.

BACKGROUND AND AIMS: Impairment in mental health associated with eating-disorder features was examined in a large, general population sample of women aged 18 to 42 years. METHOD: Participants (n = 5255) completed self-report measures of eating-disordered behaviour, mental health functioning, height and weight and socio-demographic information. RESULTS: The most common eating-disorder features were extreme concerns about weight or shape (14.6%), subjective overeating (12.7%), objective overeating (10.6%) and extreme concerns about dietary intake (10.4%). In multivariable analysis, in which mental health functioning was regressed on eating-disorder features, while also controlling for age and body weight, objective overeating (ß  =  -0.07), subjective overeating (ß â€Š = -0.07), extreme dietary restriction (ß â€Š=  -0.06) and extreme concerns about eating (ß â€Š=  -0.04) showed small, but statistically significant associations with mental health impairment, whereas extreme weight or shape concerns showed a very strong association (ß â€Š=  -0.24). CONCLUSIONS: From a clinical perspective, the findings are consistent with the importance attached to the "over-evaluation" of weight or shape as a core component of eating-disorder psychopathology. From a public health perspective, the findings indicate the need to conceive of body dissatisfaction as a target for health promotion in its own right.

The case for a national survey of eating disorders in Australia.

In this Commentary we outline the case for a national survey of eating disorders in Australia. Given the recent focus of the federal government to provide further funding for mental health research, we call for a national survey to be made a key priority. Such high-quality, nationally representative data are critically important to informing all other domains of eating disorders research in the Australian context, and to informing the research agenda internationally.

Self-report versus interview assessment of purging in a community sample of women.

OBJECTIVE AND METHODS: Agreement between self-report and interview assessment of purging behaviours was examined in a community sample of women with a high level of eating disorder symptoms (n = 324) who completed both the Eating Disorder Examination (EDE) and Eating Disorder Examination Questionnaire (EDE-Q). RESULTS: Of 46 individuals who reported any use of self-induced vomiting or laxative misuse on the questionnaire, 19 (41.7%) denied these behaviours when subsequently questioned in a face-to-face interview. These individuals had lower levels of eating disorder psychopathology, functional impairment and general psychological distress, than participants who reported purging on both the questionnaire and at interview (n = 27). CONCLUSIONS: The assumption of interview superiority in the assessment of specific aspects of eating disorder psychopathology should not be uncritically accepted. Caution should be exercised in drawing conclusions concerning the level of agreement between self-report and interview assessment of purging based on research in clinical samples.

Eating Disorder Examination Questionnaire (EDE-Q): norms for young adult women.

In order to establish norms for the Eating Disorder Examination Questionnaire (EDE-Q) among young adult women, the questionnaire was administered to a large general population sample of women aged 18-42 yr in the Australian Capital Territory (ACT) region of Australia. Normative data were derived for EDE-Q subscales and for the occurrence of specific eating disorder behaviours, for each of five age bands (18-22, 23-27, 28-32, 33-37, 38-42 yr). Mean scores (SDs) for the Restraint, Eating Concern, Weight Concern and Shape Concern subscales for the total sample (n = 5,255) were, respectively, 1.30 (1.40), 0.76 (1.06), 1.79 (1.51) and 2.23 (1.65). The mean global score was 1.52 (1.25). The regular occurrence of objective and subjective overeating episodes was reported by 10.6% and 12.7% of participants, respectively. The regular use of self-induced vomiting, laxative misuse, and use of diuretics, was reported by 1.4%, 1.0%, and 0.3%, of participants, respectively, while 2.2% of participants reported regularly using diet pills. "Extreme dietary restraint" and "excessive exercise" were reported by 3.4% and 4.9% of participants, respectively. Both attitudinal and behavioural features of eating disorder psychopathology tended to decrease with increasing age. These data will inform researchers intending to use the EDE-Q in epidemiological studies.

Risk factors for binge eating disorder: a community-based, case-control study.

BACKGROUND: Many risk factors have been implicated for eating disorders, although little is known about those for binge eating disorder. METHODS: A community-based, case-control design was used to compare 52 women with binge eating disorder, 104 without an eating disorder, 102 with other psychiatric disorders, and 102 with bulimia nervosa. RESULTS: The main risk factors identified from the comparison of subjects with binge eating disorder with healthy control subjects were certain adverse childhood experiences, parental depression, vulnerability to obesity, and repeated exposure to negative comments about shape, weight, and eating. Compared with the subjects with other psychiatric disorders, those with binge eating disorder reported more childhood obesity and more exposure to negative comments about shape, weight, and eating. Certain childhood traits and pronounced vulnerability to obesity distinguished the subjects with bulimia nervosa from those with binge eating disorder. CONCLUSIONS: Binge eating disorder appears to be associated with exposure to risk factors for psychiatric disorder and for obesity. When compared with the wide range of risk factors for bulimia nervosa, the risk factors for binge eating disorder are weaker and more circumscribed. Pre-morbid perfectionism, negative self-evaluation, and vulnerability to obesity appear especially to characterize those in whom bulimia nervosa subsequently develops.

Mode of delivery, but not questionnaire length, affected response in an epidemiological study of eating-disordered behavior.

BACKGROUND AND OBJECTIVES: The effects of questionnaire length and mode of delivery on response rates were examined in an epidemiological study of eating-disordered behavior. METHODS: Short (8 pages) and long (14 pages) questionnaires were posted or hand-delivered to a community sample of 802 women. Nonrespondents who received the first questionnaire by hand delivery received a reminder letter and replacement questionnaire by post; those who received the initial questionnaire by post were further randomized to receive the first reminder by hand delivery or by post, in short or long form. A second reminder letter and questionnaire (in short or long form) were posted to all remaining nonrespondents. RESULTS: The overall response rate was 52.9%. This is a conservative estimate of true response, because in a substantial proportion of cases (12.2%) individuals were no longer resident at the listed address. There was a significant effect of mode of delivery on response, favoring hand delivery, at both the initial mailout and first reminder. There was no effect of questionnaire length on response to the initial mailout, although overall response was significantly higher for the longer form. It was estimated that an overall response of 58.0% would have been achieved had first reminders been hand-delivered to all nonrespondents who received the initial mailout by post. CONCLUSIONS: Delivery of questionnaires by hand may be an effective way to increase response rates in epidemiological research, but little is to be gained by reducing questionnaire length.

Validity of the Eating Disorder Examination Questionnaire (EDE-Q) in screening for eating disorders in community samples.

In order to examine the concurrent and criterion validity of the questionnaire version of the Eating Disorders Examination (EDE-Q), self-report and interview formats were administered to a community sample of women aged 18-45 (n = 208). Correlations between EDE-Q and EDE subscales ranged from 0.68 for Eating Concern to 0.78 for Shape Concern. Scores on the EDE-Q were significantly higher than those of the EDE for all subscales, with the mean difference ranging from 0.25 for Restraint to 0.85 for Shape Concern. Frequency of both objective bulimic episodes (OBEs) and subjective bulimic episodes (SBEs) was significantly correlated between measures. Chance-corrected agreement between EDE-Q and EDE ratings of the presence of OBEs was fair, while that for SBEs was poor. Receiver operating characteristic (ROC) analysis, based on a sample of 13 cases, indicated that a score of 2.3 on the global scale of the EDE-Q in conjunction with the occurrence of any OBEs and/or use of exercise as a means of weight control, yielded optimal validity coefficients (sensitivity = 0.83, specificity = 0.96, positive predictive value = 0.56). A stepwise discriminant function analysis yielded eight EDE-Q items which best distinguished cases from non-cases, including frequency of OBEs, use of exercise as a means of weight control, use of self-induced vomiting, use of laxatives and guilt about eating. The EDE-Q has good concurrent validity and acceptable criterion validity. The measure appears well-suited to use in prospective epidemiological studies.

Psychotherapy for bulimia nervosa and binging.

BACKGROUND: Bulimia nervosa and like syndromes, such as binge eating disorder, are common in young Western women. A specific psychotherapy, cognitive behaviour therapy (CBT) has been developed for the treatment of bulimia nervosa. Other psychotherapies, some from a different theroretical framework, some modifications of CBT are also used. OBJECTIVES: The review aims to evaluate the psychotherapeutic treatments for those with binge eating syndromes, that have been tested in randomised controlled trials. Specifically, CBT therapy is compared with waiting list or a non-treatment group, any other psychotherapy, CBT in a "pure self-help" form and CBT augmented by exposure and response therapy. As well, the review aims to evaluate the evidence for the efficacy of other psychotherapies when compared to a no treatment control group and to evaluate the evidence for the efficacy of other psychotherapies when compared to a 'placebo' therapy. SEARCH STRATEGY: Handsearch of The International Journal of Eating Disorders since its first issue; database searches of MEDLINE, EXTRAMED, EMBASE, PSYCHLIT, CURRENT CONTENTS, LILACS, SCISEARCH, The Cochrane Collaboration Controlled Trials Register and the Cochrane Depression, Anxiety and Neurosis Group Database of Trials; citation list searching and personal approaches to authors communication are used. SELECTION CRITERIA: All studies that have tested any form of psychotherapy for adult patients with non-purging bulimia nervosa, binge eating disorder and/or EDNOS of a bulimic type, and which have applied a randomised controlled and standardized outcome methodology, are sought for the purpose of this review. DATA COLLECTION AND ANALYSIS: Data are entered into a spreadsheet programme, and into the REVMAN analysis program. Relative risk analyses are conducted of binary outcome data. The relative risk analysis is used rather than the odds ratio as the outcome measures proposed are not measuring a rare event (such as death) and the total number of studies is small. Standardized mean difference analyses are conducted of continuous variable outcome data, as the continuous outcome measures are not consistent across studies. Sensitivity analyses are conducted of a number of measures of trial quality. Data were not reported in such a way to permitsubgroup analyses, but the effect of treatment on depressive symptoms, psychosocial and/or interpersonal functioning, general psychiatric symptoms and weight is examined where possible. Chi-square tests for homogeneity are done, at 5% level of significance, using a fixed effects model. Funnel plots to evaluate presence of publication bias are completed and available in a text file upon request. MAIN RESULTS: To date, more than 1360 trials have been generated by searching and 63 trials have been evaluated in detail. Because of a relatively high number of exclusions (n=12) the trial inclusion criteria were broadened to include those with non-blinded outcome assessment, providing 25 trials for analyses. Because of incomplete published and available data, at best up to 10 studies had data available for any single analysis. The maximum number of total patients included in a single analysis is 543. The majority of studies (21) evaluate patients with bulimia nervosa of a purging type. CBT is superior to waiting list controls with respect to abstinence from binge eating (RR 0.64 CI.53-.78). CBT just fails to be significantly superior to other psychotherapies with respect to abstinence from binge eating (RR.79, CI.61-1.04). CBT in a full or less intensive form is not significantly superior to CBT in a pure self-help form. Augmentation of CBT with exposure therapy is not more effective than CBT alone. Non CBT-psychotherapies also have significantly greater abstinence rates in comparisons with wait-list controls, but there is a paucity of such studies (RR 0.67, CI.56-.81, n=3 studies). Funnel plots suggest a bias towards publication of positive outcome studies only. REVIEWER'S CONCLUSIONS: There is 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 (e.g. the majority are not blinded) and sample sizes are often very small. More trials are needed, particularly for binge eating disorder and other EDNOS syndromes, and evaluating other psychotherapies and less intensive psychotherapies.

BACKGROUND: Bulimia nervosa and like syndromes, such as binge eating disorder, are common in young Western women. A specific manual based psychotherapy, 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 psychotherapeutic treatments for those with binge eating syndromes, that have been tested in randomised controlled trials. The efficacy of CBT in the specific treatment of bulimia nervosa and binge eating disorder was evaluated. CBT therapy was compared with waiting list or a non-treatment group, any other psychotherapy, CBT in a "pure self-help" form and CBT augmented by exposure and response therapy. In addition, the review aimed to evaluate the evidence for the efficacy of other psychotherapies when compared to a no treatment control group and to evaluate the evidence for the efficacy of other psychotherapies when compared to a 'placebo' therapy.

Chi-square tests for homogeneity were done, at 5% level of significance, using a fixed effects model. Funnel plots to evaluate presence of publication bias were completed and are available in a text file upon request. MAIN RESULTS: To date, more than 1365 trials have been generated by searching and over 100 trials have been evaluated in detail. Because of a relatively high number of original exclusions (n=12) the trial inclusion criteria were broadened to include those with non-blinded outcome assessment, providing 34 trials for analyses. Because of incomplete published and available data, at best up to 12 studies had data available for any single analysis. The maximum number of total patients included in a single analysis was 602. The majority of studies evaluated patients with bulimia nervosa of a purging type. 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) like eating disorder syndromes. CBT had been used with efficacy 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 approach 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. REVIEWER'S CONCLUSIONS: There was a small body of evidence for the efficacy of cognitive-behaviour therapy in bulimia nervosa and similar syndromes, but the quality of trials was very variable (e.g. the majority were not blinded) and sample sizes were often small in comparison to pharmacotherapy trials. More trials are needed, particularly for binge eating disorder and other EDNOS syndromes, and trials evaluating other psychotherapies and less intensive psychotherapies.

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.

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.

Casemix funding in psychiatry: some problems and common pitfalls.

The aims of this study were to evaluate the accuracy of AN-DRG version 2.0 codings. Ninety-two separations, covering three of the most commonly occurring AN-DRG in psychiatry, were reviewed by a psychiatrist. The AN-DRG diagnosis was then compared to that given by morbidity coders. There was agreement for 69 (79 per cent) separations and disagreement for 18 (21 per cent) separations. Recoding of the 18 separations altered average length of stay data and the funding received. The high error rate of coding stimulated changes to the training of morbidity coders and registrars.

Women with bulimic eating disorders: When do they receive treatment for an eating problem?

Variables associated with the use of health services were examined in a prospective, community-based study of women with bulimic-type eating disorders who did (n = 33) or did not (n = 58) receive treatment for an eating problem during a 12-month follow-up period. Participants who received treatment for an eating problem differed from those who did not in several respects, including higher body weight, higher levels of eating disorder psychopathology, general psychological distress, and impairment in role functioning, deficits in specific aspects of coping style, greater awareness of an eating problem, and greater likelihood of prior treatment for a problem with weight. However, the variables most strongly associated with treatment seeking were greater perceived impairment in role functioning specifically associated with an eating problem and greater perceived inability to suppress emotional difficulties. These were the only variables that were significantly associated with treatment seeking in multivariable analysis. The findings suggest that individuals' recognition of the adverse effects of eating-disordered behavior on quality of life may need to be addressed in prevention and early intervention programs for eating disorders.

Associations between obesity and developmental functioning in pre-school children: a population-based study.

OBJECTIVE: To examine associations between obesity and impairment in developmental functioning in a general population sample of pre-school children. METHOD: Standardized medical examinations were conducted in nine consecutive cohorts of male and female children (n=9415) aged between 4.4 and 8.6 years (mean=6.0, s.d.=0.37) residing in the Lower Bavaria region of Germany. Tests designed to assess performance in subdivisions representing four broad developmental domains, namely, motor development, speech development, cognitive development and psycho-social development, were completed by all participants. RESULTS: Boys had significantly higher rates of impairment than girls. The prevalence of obesity in boys was 2.4%, whereas in girls it was 4.3% (chi (2)=21.51, P< 0.01). After controlling for age, gender, year of recruitment and other potential covariates, the prevalence of impairment in gross motor skills was higher among obese male children than normal-weight male children (adjusted odds ratio=1.76, 95% confidence interval (CI)=1.02, 3.01, P< 0.05), whereas the prevalence of impairment in the ability to focus attention was higher in obese female children than normal-weight female children (adjusted odds ratio=1.86, 95% CI=1.00, 3.44, P< 0.05). CONCLUSIONS: The findings suggest that gender-specific associations between obesity and impairment in specific aspects of developmental functioning may be evident in younger children.

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.

The 'expert' in problem-based and case-based learning: necessary or not?

BACKGROUND: Problem-based learning (PBL) and other small-group teaching methods which incorporate principles of adult learning, are exciting innovations in medical education. In the application of these methods to medical curricula many schools have introduced non-expert tutors. However, research evaluating the effectiveness of non-expert lead teaching has been inconclusive. AIM: The present study aim was to compare the outcome of teaching in small groups facilitated by either an 'expert' or a 'non-expert' tutor, in a single topic area. METHOD: Fourth-year medical students were allocated randomly to teaching of eating disorders either by a non-expert or an expert tutor. Outcomes were evaluated by (i) a knowledge test, and (ii) self-report ratings by tutors and students of their learning methods and other qualities. RESULTS: The study found that while the non-expert tutor was rated more highly for her group management skills, and she also rated her students more highly in the area of oral communication, students who were taught by the expert scored higher in the end-of-course test in the topic area. CONCLUSION: The findings suggest that caution should be exercised, and the need for more research before widespread adoption of teaching by non-expert tutors.

Eating disorder patient referrals from a population region 1977-1986.

Three hundred and forty-three eating disorder patients (50% anorexia nervosa, 37% bulimia and 13% atypical eating disorder) were seen by the eating disorder service in the Wellington (New Zealand) region between 1977 and 1986. Ninety-six per cent were female. Annual rate of referral for anorexia nervosa remained stable at 5 per 100,000 population (34 per 100,000 females aged 15-29 years). Annual referral rate for bulimia increased from 6 to 44 per 100,000 females aged 15-29 years.
