The validity of the eating disorder examination and its subscales

Binge eating in the bariatric surgery population: a review of the literature

OBJECTIVE

This article reviews the status of the literature addressing clinically significant binge eating in the bariatric surgery patient. The goal is to provide a background that will guide patients, surgeons, and mental health practitioners toward the most successful long-term surgical outcome when binge eating is identified.

METHOD

Pubmed and Medline search with subsequent reference list search of identified articles. We searched literature through April 2006 on the influence of binge eating (BE) on surgical outcome.

RESULTS

Those with pre-surgical BE are more likely to retain the eating pathology and, if they do, to have poorer weight loss outcome. Many people who binge ate prior to surgery report continued feelings of loss of control when eating small amounts of food after surgery. Studies that employed the DSM-IV definition of a binge episode reported absence of BE after surgery, unlike those that modified binge criteria after surgery.

CONCLUSION

Clinically significant BE is related to poorer surgical outcomes, and additional interventions may be needed to improve long term outcomes. Though surgery does alter body's physiology, claims that the psychological aspects of BE are "cured" by obesity surgery must be viewed with caution. Researchers and practitioners must reach a consensus on how to define BE after gastric surgery so that future long-term prospective studies may further evaluate the effect of BE on surgical outcome and vice versa.

Natural history and predictors of disturbed eating behaviour in girls with Type 1 diabetes

AIM

To determine the natural history and psychosocial predictors of disturbed eating behaviour in girls with Type 1 diabetes (T1D) over a 1-year period.

METHODS

One hundred and six girls with T1D, 9-13 years of age at Time 1, completed a Children's Eating Disorder Examination (cEDE) interview at Time 1 and again 1 year later (Time 2). Potential Time 1 predictors of Time 2 disturbed eating behaviour were body mass index (BMI), self-esteem, depressive symptoms, attachment to parents, and parental eating attitudes. Glycated haemoglobin (HbA(1c)) was measured.

RESULTS

Disturbed eating behaviour was reported by 14% (15/106) of girls at Time 1, and 17% (18/106) at Time 2, and persisted in 8/15 girls over 1 year. Lower self-esteem, higher BMI and more disturbed maternal eating attitudes at Time 1 accounted for 35% of the variance in Time 2 cEDE score, while higher BMI and more disturbed attachment to one's mother predicted new-onset disturbed eating behaviour at Time 2. Glycaemic control was not associated with or predicted by disturbed eating behaviour.

CONCLUSIONS

There was only moderate stability in disturbed eating behaviour status over a 1-year period. In this preliminary study, disturbed eating behaviour was associated with and, to a lesser degree, predicted by physical, psychological and family factors. Although the long-term clinical course of the mild disturbances identified is not known, prevention and early intervention efforts in this high-risk medical group should begin in the pre-teen years, and should probably target multiple factors in order to prevent the persistence and worsening of disturbed eating behaviour and its medical sequelae.

Prevalence of eating disorders in a Spanish community adolescent sample

OBJECTIVE

To describe the prevalence of eating disorders (ED) among Spanish adolescents and to present the reliability of the Catalan version of the EDE-12.

METHOD

A community sample of 1155 participants, and a risk sample of 93 participants, aged between 10.9 and 17.3 years old, from the city of Barcelona participated in the study. The study involved two stages: first, an initial screening with the Eating Disorder Inventory-2 (EDI-2), and second, a structured clinical interview (EDE-12). Three scales of the EDI-2 (Drive for thinness, Body dissatisfaction and Bulimia) were used to select the at risk sample; the Eating Disorders Examination-12 (EDE-12) was only administered to the at-risk sample.

RESULTS

A 1.28% of the total sample was detected as ED (2.31% of girls and 0.17% of boys). Reliability coefficients of EDE-12 ranged from medium to high.

DISCUSSION

Symptoms of anorexia and bulimia nervosa were higher among girls than boys. Preoccupation with maintained low weight, with body image and shape, and taking excessive exercise in order to loose weight, are increasing among Spanish adolescents. Prevalence rate of ED is lower than other studies with Spanish' adolescents sample, and could be related to the sample age (13.16% of the sample is smaller than 12 years old), and to the non response bias to the interview because the assessment was carried out in the school setting.

Psychosocial and physical impairment in overweight adolescents at high risk for eating disorders

OBJECTIVE

Many overweight adolescents display elevated risk for the development of eating disorders, as seen in higher rates of weight/shape concerns and disordered eating behaviors, but the extent of impairment in this subset of high-risk adolescents has not been explored.

RESEARCH METHODS AND PROCEDURES

Eighty-one overweight adolescents (63% girls) presenting for an Internet-based weight loss program were assessed at baseline using the Eating Disorder Examination Questionnaire, the Depression, Anxiety, and Stress Scale, and the Pediatric Quality of Life questionnaire. Adolescents who earned elevated scores on both the Weight Concern and Shape Concern subscales of the Eating Disorder Examination Questionnaire were considered at high risk for the development of eating disorders (56.8%).

RESULTS

Comparisons of high- and normal-risk groups revealed that high-risk adolescents reported higher levels of depression [F(3,76) = 5.75, p = 0.019], anxiety [F(3,76) = 5.67, p = 0.020], and stress [F(3,75) = 8.50, p = 0.005], and greater impairments in physical health [F(3,77) = 10.7, p = 0.002], emotional functioning [F(3,77) = 5.3, p = 0.024], and social functioning [F(3,77) = 10.0, p = 0.002]. There were no differences in school functioning [F(3,77) = 1.5, p = 0.219]. Among the high-risk adolescents, over half (52.2%) reported binge eating at least once in the past month.

DISCUSSION

Results suggest that overweight adolescents at high risk for the development of eating disorders also experience elevated levels of negative affect, impairment in health-related quality of life, and eating disturbances, although prospective data are needed to determine the directionality between eating disorder pathology and general psychopathology. Further research is warranted to evaluate whether behavioral weight loss interventions should be enhanced for this high-risk subset.

Detailed analysis of binges in obese women with binge eating disorder: Comparisons using multiple methods of data collection

OBJECTIVE

This study compares multiple methods of assessing food intake in obese women with binge eating disorder (BED).

METHOD

Twelve women meeting BED criteria completed six random 24-hour dietary recalls, engaged in a laboratory binge eating episode, and completed the EDE interview.

RESULTS

There was not a significant difference in total or macronutrient intake when binge eating episodes were assessed via the recall and laboratory methods. However, within-individual correlations were low for the size of different binge eating episodes collected by the two methods. Significantly more calories were consumed during objective than during subjective binges, and significant differences in macronutrient composition were observed. Meal patterning data collected by the EDE and the recalls were comparable.

CONCLUSION

The findings suggest only moderate agreement between the methods that were examined. Future investigations with larger sample sizes are needed to examine the relationship among these different methods of assessing food intake.

Role of therapeutic alliance in family therapy for adolescent anorexia nervosa

OBJECTIVE

The purpose of this study is to examine the role of therapeutic alliance in predicting treatment dropout, response and outcome in a cohort of adolescents with anorexia nervosa (AN) and their families who were treated using a manualized form of family-based therapy (FBT).

METHOD

Independent assessors scored early and late therapeutic alliances for patients and parents using the Working Alliance Inventory-Observer (WAIo). Outcomes were weights and scores on the subscales of the Eating Disorder Examination at the end of 12 months of FBT.

RESULTS

Therapeutic alliance throughout treatment was strong both for adolescents and for their parents. A strong early alliance with adolescents was associated with early treatment response in terms of weight gain. A strong early alliance with parents prevented dropout, whereas a strong late parental alliance predicted their child's total weight gain at the end of treatment.

CONCLUSION

Therapeutic alliance in both patients and parents treated with FBT is generally strong and likely contributes to treatment retention and treatment outcome.

Predictors of dropout and remission in family therapy for adolescent anorexia nervosa in a randomized clinical trial

OBJECTIVE

The purpose of this study is to explore the predictors of dropout and remission in the treatment of adolescent anorexia nervosa (AN) using family therapy.

METHOD

Data derived from a randomized clinical trial comparing short and long term family therapy for adolescents with AN were used. A rotated component analysis was employed to reduce the number of variables and to address problems of collinearity and multiple testing. Dropout was defined as participating in less than 80% of the assigned therapy. Participants were classified as remitted if they obtained an ideal body weight greater than 95% and a global eating disorder Examination score within two standard deviations of community norms at the end of 12 months.

RESULTS

Co-morbid psychiatric disorder and being randomized to longer treatment predicted greater dropout. The presence of co-morbid psychiatric disorder, being older, and problematic family behaviors led to lower rates of remission. A reduction of child behavioral symptoms, a decline in problematic family behaviors, and early weight gain were all within treatment changes that increased the chance of remission.

CONCLUSION

Co-morbid psychiatric disorder, family behaviors, and early response to treatment are important factors when predicting dropout and remission in family therapy for adolescent AN.

An investigation into the psychometric properties of the Stirling Eating Disorder Scales

The Stirling Eating Disorder Scales (SEDS) are widely used in clinical practice, however evidence regarding the internal consistency and validity of the measure is limited. The aim of this study was to investigate the psychometric properties of the SEDS in a mixed eating disorder population. The SEDS and the Eating Disorder Examination (EDE) were administered to 241 consecutive patients attending an adult out-patient eating disorder service in the UK. The internal consistency of the overall SEDS was good, but there was variation in the internal consistency of the individual subscales. There were differences across diagnosis for all SEDS subscales, and some significant correlations were found between the EDE and SEDS subscales. It was not possible to replicate the derivation of the original SEDS subscales using a principal components analysis (PCA); further analysis was conducted on the new subscales that were identified. It is suggested that information obtained from the administration of the SEDS should be interpreted with caution, and also that further exploration of the psychometric properties of the SEDS is warranted.

Impulsivity in women with eating disorders: problem of response inhibition, planning, or attention?

OBJECTIVE

Impulsivity is generally believed to be more characteristic of individuals with bulimic than with restrictive eating disorders (EDs). However, studies have not exhaustively explored the association between EDs and various component dimensions of the impulsivity construct.

METHOD

We conducted a multidimensional assessment of impulsivity in 84 women with bulimia nervosa (BN), 37 with anorexia nervosa (AN: 19 restricters and 18 bingers-purgers), and 61 normal-control participants. To assess multiple components of impulsivity, participants completed a battery of self-report questionnaires and a performance test.

RESULTS

Compared with normal-control participants, all ED groups showed attentional problems. However, only women suffering BN or AN-binge purge subtype showed elevations on motoric forms of impulsivity, whereas women with BN were the only group to report tendencies toward reckless behavior.

CONCLUSION

These findings suggest that binge-eating behavior coincides with problems of response inhibition, whereas a risk-taking attitude may be a unique characteristic of individuals with BN.

Do supplementary items on the eating disorder examination improve the assessment of adolescents with anorexia nervosa?

OBJECTIVE

Given that adolescents with anorexia nervosa (AN) typically have lower scores on the Eating Disorder Examination (EDE) than expected, the current study examined whether the inclusion of eight supplementary items developed by the authors of the EDE better captured the symptoms of adolescents with AN.

METHOD

A dataset consisting of EDEs from 86 adolescents was examined by 3 primary methods: (1) baseline subscale scores were compared before and after the addition of the supplementary items, (2) the internal consistency of the EDE with the addition of these items was examined, and (3) each of these items was compared before and after treatment.

RESULTS

After the addition of the supplementary items, the Eating Concern and Weight Concern subscales were significantly increased, whereas the Restraint subscale was significantly decreased, and the Shape Concern subscale was unchanged. Internal consistency was improved on the Eating Concern, Weight Concern, and Shape Concern subscales, and was decreased on the Restraint subscale. Three of eight items showed a significant decrease with treatment.

CONCLUSION

Although the addition of some of these eight supplementary items better captured the psychopathology of adolescents with AN, scores were still substantially below expected, indicating that the exploration of other methods of assessment is needed.

Binge eating in overweight treatment-seeking adolescents

OBJECTIVE

To examine the frequency and recency of binge eating in relation to psychopathology in overweight, treatment-seeking adolescents.

METHODS

We investigated psychological correlates of the frequency and recency of reported loss of control (LOC) eating episodes in 160 overweight (body mass index [BMI]: 40.7 +/- 8.8 kg/m(2)) adolescents. On the basis of the responses to the eating disorder examination (EDE), participants were categorized into one of four groups: full-syndrome binge eating disorder (BED); recent but infrequent binge eating (episodes within the 3 months before interview; RECENT-BINGE); remote and infrequent LOC eating (episodes occurring >3 months before assessment; PAST-LOC), or no history of LOC episodes (NE).

RESULTS

The BED group reported higher EDE scores (global, p < .01), and more negative mood and anxiety than all other groups (p's < .01). Compared with NE, RECENT-BINGE also reported more anxiety and higher EDE scores (p's < .01).

CONCLUSIONS

Overweight, treatment-seeking adolescents with BED are clearly distinguishable from teens without the disorder on measures of eating-related psychopathology, mood, and anxiety. RECENT-BINGE, but not PAST-LOC, is also associated with significantly greater eating-related and general psychopathology.

The eating disturbed spectrum in relation with coping and interpersonal functioning

Although much has been written with regards to the interpersonal functioning of eating-disordered women, research in the domain of eating disorders (ED) has still overlooked the complex relationships between stressful life events, coping styles, social and marital support while considering the ED spectrum.

OBJECTIVE

This study evaluates to what extent stressful life events, coping styles, and social support represent useful concepts for differentiating between four groups of participants with varying severity of eating preoccupations and disturbances.

METHOD

One hundred twenty-five participants were divided into four groups: 40 women suffering from ED, 21 women in remission from an ED, 33 women with intense weight and shape preoccupations, and 31 women without eating preoccupations. Each participant completed the Eating Disorder Evaluation, as well as questionnaires concerning stressful life events, coping styles, social support, and couple satisfaction.

RESULTS

There were significant differences between the groups in terms of negative impact of stressful events, social support, as well as task-oriented and emotion-oriented coping styles. Significant differences were not found between the groups for couple satisfaction.

CONCLUSION

It appears that accurate cognitive appraisal of stressful situations, adaptive coping styles and improvement of the social network represent interesting dimensions to include in prevention and treatment programs for ED. Moreover, for women in remission from an ED, an effective relapse prevention strategy could be to learn to make better use of their social network.

Girls with anorexia nervosa as young adults: personality, self-esteem, and life satisfaction

OBJECTIVE

The current study evaluated personality, self-esteem, and life satisfaction in former patients with different outcomes of childhood and adolescent-onset anorexia nervosa (AN).

METHODS

Forty-four female patients with AN were assessed 8.5 +/- SD 3.4 years after treatment start with a clinical interview and questionnaires including the Temperament and Character Inventory (TCI) and the Rosenberg Self-Esteem Scale. Self-esteem and general life satisfaction in former patients were compared with women in a large population study.

RESULTS

Former AN patients with no eating disorder and normal eating attitudes at follow-up (n = 21 [48%]) had similar TCI profiles and self-esteem as samples from normal populations, whereas participants with poorer outcome had significantly lower TCI Self Directedness, self-esteem, and life satisfaction scores. Life satisfaction was reduced in all outcome groups and was strongly associated with self-esteem.

CONCLUSION

Personality, self-esteem, and life satisfaction varied significantly between outcome groups. The results indicate that young patients with AN with a good outcome may have normal personality and self-esteem features in young adulthood.

Eating and weight control behaviors among middle school girls in relationship to body weight and ethnicity

This study examined the links among body mass index (BMI), weight control practices, binge eating, and eating disorders in 1164 middle school girls. Both the prevalence and frequency of weight control behaviors increased as BMI increased, but binge eating was reported approximately equally by girls across the BMI spectrum.

What is remission in adolescent anorexia nervosa? A review of various conceptualizations and quantitative analysis

OBJECTIVE

The current article evaluated models of remission in anorexia nervosa (AN).

METHOD

A dataset from 86 adolescents with AN was used to model definitions of remission by using (a) Morgan-Russell categories, (b) criteria proposed by Pike, (c) criteria proposed by Kordy, et al. (d) DSM-IV-text revision criteria, (e) other weight thresholds, (f) psychological symptoms (Eating Disorder Examination [EDE] scores), and (g) combinations of these.

RESULTS

The mean age was 15.2 +/- 1.6 years. Remission rates varied from 3% to 96% depending on the method used. Combining percent ideal body weight and EDE scores appeared to reduce the variability in rates, capture the most meaningful aspects of remission, and avoid the pitfalls of other methods.

CONCLUSION

These methods of defining remission produce a wide range of outcomes, demonstrating the importance of defining remission consistently. Weight and psychological variables combined appear most important in defining remission.

Cognitive-behavioral therapy for adolescents with binge eating syndromes: a case series

OBJECTIVE

Published empirically based studies of psychotherapies for bulimia nervosa (BN) have been conducted solely with adult populations. The current study extends the extant literature by piloting a version of cognitive-behavioral therapy (CBT) for BN adapted for an adolescent population.

METHOD

The participants were referred for treatment for binge eating and purging behaviors at a university clinic. Patients received pretreatment and posttreatment interviews assessing the frequency of their binge eating and purge behaviors, and they also completed pretreatment and posttreatment assessments with the Eating Disorders Examination (EDE).

RESULTS

Results indicated significant reductions in the frequency of binge eating from pretreatment to posttreatment. Furthermore, all subscale scores of the EDE showed significant declines from pretreatment to posttreatment.

CONCLUSION

The authors concluded that CBT adapted for adolescents with bulimic symptoms appears to be a promising intervention worthy of further study in adolescents.

The impact of childhood sexual abuse in anorexia nervosa

OBJECTIVE

The aim of this study was to examine the impact of childhood sexual abuse (CSA) on clinical characteristics and premature termination of treatment in anorexia nervosa (AN).

METHOD

The participants were 77 consecutive patients with AN admitted to an inpatient eating disorders unit. The patients were assessed in terms of eating disorder symptoms, general psychopathology, and CSA history at admission to hospital.

RESULTS

Thirty-seven patients (48%) reported a history of CSA before the onset of the eating disorder. Individuals with a history of CSA reported significantly greater psychiatric comorbidity, including higher levels of depression and anxiety, lower self-esteem, more interpersonal problems, and more severe obsessive-compulsive symptoms. Patients with the binge-purge subtype of AN (AN-BP) were significantly more likely to report a history of CSA prior to the onset of the eating disorder as compared with patients with the restricting subtype (AN-R) of the illness (65% of the AN-BP patients vs. 37% of the AN-R patients; p<.02). Contrary to our predictions, abused patients were not significantly more likely to dropout of treatment overall. However, patients of the binge-purge subtype (AN-BP) with a history of CSA were significantly more likely to terminate treatment prematurely as compared with the other patients.

CONCLUSIONS

Consistent with previous findings, the present results indicate that the prevalence of CSA is high among individuals seeking inpatient treatment for AN. A history of CSA was associated with greater psychiatric disturbance overall and a higher rate of dropout for patients of the binge-purge subtype.

A comparison of sequenced individual and group psychotherapy for patients with bulimia nervosa

OBJECTIVE

The current study examined the effectiveness of individual (IND) versus group (GRP) therapy for patients with bulimia nervosa (BN), using a manual of sequenced treatment with cognitive-behavioral therapy (CBT) followed by interpersonal psychotherapy (IPT).

METHOD

Eighty-six participants with BN were matched and randomized to 23 sessions of IND or GRP. Participants were measured pretreatment and posttreatment and at 1-year and 2.5-year follow-ups using both intent-to-treat and completer samples.

RESULTS

The intent-to-treat analysis revealed that the percentage of participants recovered and remitted was equivalent between IND and GRP. Significant group differences were found between completers on binge eating and compensatory behavior with greater improvement for IND. On most measures, effect sizes were larger for IND at 1-year follow-up.

CONCLUSION

Sequencing CBT and IPT worked well in both IND and GRP formats. We found few outcome differences between IND as opposed to GRP.

The female athlete triad exists in both elite athletes and controls

PURPOSE

To examine the prevalence of the female athlete triad (the Triad) in Norwegian elite athletes and controls.

METHODS

This study was conducted in three phases: (part I) screening by means of a detailed questionnaire, (part II) measurement of bone mineral density (BMD), and (part III) clinical interview. In part I, all female elite athletes representing the national teams at junior or senior level, aged 13-39 yr (N = 938) and an age group-matched randomly selected population-based control group (N = 900) were invited to participate. The questionnaire was completed by 88% of the athletes and 70% of the controls. Based on data from part I, a stratified random sample of athletes (N = 300) and controls (N = 300) was selected and invited to participate in parts II and III of the study. 186 athletes (62%) and 145 controls (48%) participated in all parts of the study.

RESULTS

Eight athletes (4.3%) and five controls (3.4%) met all the criteria for the Triad (disordered eating/eating disorder, menstrual dysfunction, and low BMD). Six of the athletes who met all the Triad criteria competed in leanness sports, and two in nonleanness sports. When evaluating the presence of two of the components of the Triad, prevalence ranged from 5.4 to 26.9% in the athletes and from 12.4 to 15.2% in the controls.

CONCLUSION

Our results support the assumption that a significant proportion of female athletes suffer from the components of the Triad. In addition, we found that the Triad is also present in normal active females. Therefore, prevention of one or more of the Triad components should be geared towards all physically active girls and young women.

Can collaboration between education and health professionals improve the identification and referral of young people with eating disorders in schools? A pilot study

In this pilot study, a number of different methods of identifying young people with eating disorders in schools were compared. Pupils aged 16-18 years from 3 schools in the South West of the UK participated (389 boys and 374 girls in total). A self-report questionnaire (EDE-Q) was found to be the most effective method of case identification. However, very few of these cases accepted the offer of help and it was strongly suspected that other cases went undetected despite teacher, parent and school nurse guidance. Implications for future early intervention studies are discussed.

Eating patterns and breakfast consumption in obese patients with binge eating disorder

This study examined eating patterns and breakfast consumption, and their relationships to weight and binge eating, in obese individuals with binge eating disorder (BED). One-hundred seventy-three consecutively evaluated men (n=46) and women (n=127) with BED were administered semi-structured interviews and self-report measures to assess the frequency of meals and snacks eaten, as well as binge eating and eating disorder features. Overall, those who consumed more frequent meals, particularly breakfast, and snacks, weighed less. Breakfast, which was eaten on a daily basis by less than half of participants (n=74; 43%), was the least frequently eaten meal of the day. Participants (n=56; 32%) who ate three meals per day weighed significantly less, and had significantly fewer binges, than participants (n=117; 68%) who did not regularly eat three meals per day. Thus, eating more frequently, having breakfast and consuming three meals every day, have potentially important clinical applications for the treatment of BED given that the effectiveness of specific interventions within treatments for BED are unknown, and that weight loss outcome for BED has been poor.

Binge Eating Disorder and Night Eating Syndrome: A Comparative Study of Disordered Eating

The authors compared eating patterns, disordered eating, features of eating disorders, and depressive symptoms in persons with binge eating disorder (BED; n = 177), with night eating syndrome (NES; n = 68), and in an overweight comparison group without BED or NES (comparison; n = 45). Participants completed semistructured interviews and several established measures. Depressive symptoms were greater in the BED and NES groups than in the comparison group. NES participants ate fewer meals during the day and more during the night than BED and comparison participants, whereas BED participants ate more during the day than the comparison participants. BED participants reported more objective bulimic and overeating episodes, shape/weight concerns, disinhibition, and hunger than NES and comparison participants, whereas NES participants reported more eating pathology than comparison participants. This evaluation provides strong evidence for the distinctiveness of the BED and NES constructs and highlights their clinical significance.

The Minnesota Eating Behavior Survey: a brief measure of disordered eating attitudes and behaviors

This article describes details of the development and psychometric characteristics of a brief self-report inventory for assessing attitudes and behaviors symptomatic of eating disorders that is currently in use in a longitudinal study of over 700 families with 11-year-old or 17-year-old twin girls. The Minnesota Eating Behavior Survey (MEBS), formerly the Minnesota Eating Disorder Inventory, is a 30-item measure developed for use with children as young as 10 years as well as adults. An examination of the MEBS's psychometric properties in a large, community sample of girls, women, and men demonstrated good factor congruence, internal consistency reliability, three-year stability, as well as evidence of concurrent and criterion validity. This questionnaire has promise as a screening and assessment measure for eating disturbance in cross-sectional and longitudinal research involving individuals of a wide range of ages.

Ethnicity and sampling bias in binge eating disorder: Black women who seek treatment have different characteristics than those who do not

OBJECTIVE

The current study investigated sampling bias as it affects recruited clinic samples of Black and White women with binge eating disorder (BED).

METHODS

Clinical characteristics of a recruited clinic sample (35 Black and 302 White consecutively evaluated women) with BED were compared with a community sample of Black and White women with BED drawn from the New England Women's Health Project. The clinic and community groups met the same definition of BED and were assessed with identical methods.

RESULTS

Among White women, the clinic and community samples differed on some features (higher body mass index [BMI], and greater eating concerns and shape concerns in the clinic sample) but these differences reflected small to moderate effects sizes. In contrast, among Black women, the clinic sample had substantially higher levels (large effect sizes) of several features of eating disorders (eating concerns, dietary restraint, and shape concern), higher (moderate effect size) BMI, but lower frequency of binge eating (moderate effect size) than the community sample. A comparison of Black and White women within the clinic sample revealed little difference in clinical presentation, except for the significantly higher BMI among Black women.

CONCLUSION

A sampling bias appears to exist between both White and Black recruited clinic samples of women with BED, although the bias appears to be substantially greater for Black women. Black women with BED who seek treatment have significantly different characteristics than those who do not.

Purging disorder: an ominous variant of bulimia nervosa?

OBJECTIVE

The current study evaluates the clinical significance and distinctiveness of purging disorder (PD), an eating disorder characterized by recurrent purging in the absence of objective binge episodes (OBE) among normal-weight individuals.

METHOD

Women with PD (n = 37), bulimia nervosa (BN; n = 39), or no eating disorder (n = 35) completed clinical assessments. Women with PD (n = 23) and BN (n = 25) completed 6-month follow-up assessments.

RESULTS

Compared with controls, both eating-disordered groups reported significantly higher eating, Axis I, and Axis II pathology. Compared with BN, PD was associated with significantly lower eating concerns, disinhibition, and hunger. At 6-month follow-up, rates of remission did not differ significantly between PD and BN, and crossover between disorders was rare.

CONCLUSION

PD appears to be a clinically significant and potentially distinctive eating disorder.

Why do adolescents with bulimia nervosa choose not to involve their parents in treatment?

BACKGROUND

Although the use of family therapy for adolescents with anorexia nervosa is well established, there has been limited research into the efficacy of family therapy in adolescents with bulimia nervosa (BN). No previous research has investigated why individuals with BN do or do not involve their parents in treatment. This is an exploratory study aimed at determining whether there are any differences between these individuals in terms of eating disorder symptomatology, psychopathology, familial risk factors, patients' perception of parental expressed emotion (EE) and family functioning.

METHODS

Participants were 85 adolescents with BN or Eating Disorder Not Otherwise Specified, recruited to a randomised controlled evaluation of the cost-effectiveness of cognitive-behavioural guided self-care vs. family therapy. Participants were interviewed regarding the history of their eating disorder and completed self-report measures.

RESULTS

Patients who did not involve their parents in treatment were significantly older, had more chronic eating disorder symptoms, exhibited more co-morbid and impulsive behaviours and rated their mothers higher in EE. However, they did not have more severe eating disorder symptomatology.

CONCLUSIONS

These preliminary findings, although in need of replication with a larger sample and limited by the attrition rate in some of the self-report measures, indicate that patients who did not involve their parents in treatment may perceive their mothers as having a more blaming and negative attitude towards the patient's illness. Public awareness about BN needs to be raised, focusing on reducing the stigma and negative views attached to this illness.

Girls with anorexia nervosa as young adults. Self-reported and parent-reported emotional and behavioural problems compared with siblings

This follow-up study had three objectives: 1) to investigate emotional and behavioural problems, adaptive functioning and substance use in former anorexia nervosa (AN) patients compared with siblings, 2) to compare information obtained from different informants, and 3) to compare questionnaire results with interview results. Fifty (of 55) female AN patients, representative for AN patients under 18 years referred to county health services, were assessed at a mean of 8.8 years after treatment start with the Young Adult Self-Report and the Young Adult Behaviour Checklist (mean age 23.1 years). In all, 48 patients, 25 siblings, 33 mothers and 27 fathers participated in the questionnaire study. Although 41/50 (82 %) had recovered from their eating disorder, the former AN patients had substantially more self-reported and parent-reported problems than their siblings, particularly with regard to Internalising Problems and on the Anxious/Depressed syndrome scale. Cross-informant agreement between the parents and between parents and patients was high, but low between parents and siblings. The patients with psychiatric diagnoses at follow-up had substantially higher problem scores than those without diagnoses both on the self-report and the parent-report, supporting the validity of the questionnaires. In conclusion, the self- and parent-reports showed a high level of Internalising Problems and were useful instruments in the assessment of former AN patients.

Reliability and validity of the child version of the Eating Disorder Examination: a preliminary investigation

OBJECTIVE

The Eating Disorder Examination (EDE) is a reliable and valid semistructured interview that measures the specific psychopathology of anorexia nervosa (AN) and bulimia nervosa. The current study aims to investigate the psychometric properties of the child adaptation of the EDE (ChEDE 12.0).

METHOD

The ChEDE was administered to 15 children with AN, 15 children with other clinical eating disturbances, and two groups of 15 age-matched controls. The groups were compared using a two-sample matched groups design.

RESULTS

Alpha coefficients for each of the ChEDE subscales indicated a high degree of internal consistency, and interrater reliability was found to be high (r = .91 to r = 1.00). The subscale scores of the AN group were significantly higher than those of the other groups, whereas the other eating disturbance group did not differ from its control group.

DISCUSSION

The ChEDE differentiates children with AN from children with other forms of clinical eating disturbance and control children.

Inter-rater and test-retest reliability of the Spanish language version of the eating disorder examination interview: clinical and research implications

BACKGROUND

To examine the inter-rater and test-retest reliability of the Spanish Language version of the Eating Disorder Examination (S-EDE) in monolingual Latina women. Established measures are needed to study Latino groups, and short-term test-retest reliability findings are needed to provide context for clinical treatment and outcome studies.

METHODS

Inter-rater reliability (IRR) and short-term (5-14 days) test-retest reliability (TRR) of the S-EDE (using intraclass correlation coefficients [ICCs]) were examined in a non-clinical study group of 60 monolingual Latina women.

RESULTS

IRR was excellent for objective bulimic episodes (ICC = 0.99) but was modest for subjective bulimic episodes (ICC = 0.55). TRR was good for objective bulimic episodes (ICC = 0.79) but was unacceptable for subjective bulimic episodes (ICC = 0.22). IRR and TRR kappa coefficients (0.56 and 0.37, respectively) for identifying the presence or absence of objective bulimic episodes were modest. For the S-EDE subscales, both IRR (ICCs ranged from 0.80 to 0.98) and TRR (ICCs ranged from 0.67 to 0.90) were good to excellent.

CONCLUSIONS

These findings provide preliminary support for the reliability of the S-EDE for use with Latina women. The constructs of eating disorder psychopathology measured by the S-EDE subscales (restraint, eating concern, weight concern, and shape concern) and the core feature of binge eating (objective bulimic episodes) show high short-term consistency. The results for subjective bulimic episodes are consistent with previous studies that have questioned whether these eating behaviors are reliable indicators of eating disorders. Additional evaluation is needed with clinical groups.

A comparison of short- and long-term family therapy for adolescent anorexia nervosa

OBJECTIVE

Research suggests that family treatment for adolescents with anorexia nervosa may be effective. This study was designed to determine the optimal length of such family therapy.

METHOD

Eighty-six adolescents (12-18 years of age) diagnosed with anorexia nervosa were allocated at random to either a short-term (10 sessions over 6 months) or long-term treatment (20 sessions over 12 months) and evaluated at the end of 1 year using the Eating Disorder Examination (EDE) between 1999 and 2002.

RESULTS

Although adequately powered to detect differences between treatment groups, an intent-to-treat analysis found no significant differences between the short-term and long-term treatment groups. Although a nonsignificant finding does not prove the null hypothesis, in no instance does the confidence interval on the effect size on the difference between the groups approach a moderate .5 level. However, post hoc analyses suggest that subjects with severe eating-related obsessive-compulsive features or who come from nonintact families respond better to long-term treatment.

CONCLUSIONS

A short-term course of family therapy appears to be as effective as a long-term course for adolescents with short-duration anorexia nervosa. However, there is a suggestion that those with more severe eating-related obsessive-compulsive thinking and nonintact families benefit from longer treatment.

Low bone mineral density is two to three times more prevalent in non-athletic premenopausal women than in elite athletes: a comprehensive controlled study

OBJECTIVE

To compare bone mineral density (BMD), investigate factors associated with BMD, and examine the prevalence of low BMD in athletes and non-athletic controls.

METHODS

The study included a questionnaire (part I), measurement of BMD (part II), and a clinical interview (part III). All Norwegian female athletes on national teams (n = 938) and an aged matched random sample of non-athletic controls (n = 900) were invited to participate. The questionnaire was completed by 88% of athletes and 70% of controls. A random sample of these athletes (n = 300) and controls (n = 300) was invited to participate in parts II and III. All parts were completed by 186 athletes (62%) and 145 controls (48%).

RESULTS

Mean (standard deviation) total body (TB) BMD was higher (p<0.001) in athletes (1.21 (0.09) g/cm2) than in controls (1.18 (0.08) g/cm2), and higher (p<0.001) in high impact (HI) sports athletes than in medium impact (MI) and low impact (LI) sports athletes. In athletes, body weight and impact loading sports were positively associated, and percent body fat and eating disorders were negatively associated with TB BMD. Body weight and weight bearing activities were positively associated and menstrual dysfunction was negatively associated with TB BMD in controls. A higher percentage of controls (28.3%) than athletes (10.7%) had low BMD (p<0.001).

CONCLUSION

Female elite athletes have 3-20% higher BMD than non-athletic controls and HI sports athletes have 3-22% higher BMD compared with MI and LI sports athletes. Low BMD is two to three times more common in non-athletic premenopausal women than in elite athletes.

Identification and treatment of eating disorders in women with type 1 diabetes mellitus

A series of case reports in the early 1980s and prevalence studies in the 1990s highlighted the serious medical consequences of coexisting eating disorders and diabetes mellitus. Diabetes-specific treatment issues, such as the need to carefully monitor diet, exercise, and blood glucose, may contribute to the development of eating disorder symptoms among women with diabetes mellitus. The attention to food portions and bodyweight that is part of routine diabetes mellitus management parallels the rigid thinking about food and body image found in women with eating disorders who do not have diabetes mellitus. Additionally, intensive insulin management of diabetes mellitus, the current standard of care, has been shown to be associated with bodyweight gain. Following from this, it may be that the very goals of state-of-the-art diabetes mellitus care increase the risk for developing an eating disorder. Once an eating disorder and recurrent insulin omission becomes entrenched, a pattern develops which is hard to break - one of chronic hyperglycemia, depressed mood, fear of bodyweight gain, and frustration with diabetes management. Eating disorders predispose women with diabetes mellitus to many complex medical risks. For example, insulin omission and reduction, eating disorder symptoms unique to diabetes mellitus, are strongly associated with an increased risk of diabetic ketoacidosis and with microvascular complications of diabetes mellitus such as retinopathy. For this reason, it is critical that diabetes mellitus clinicians understand more about eating disorders so as to improve the likelihood of early detection, appropriate treatment, and prevention of acute and long-term medical complications within this high-risk group of women.

The relationship of disordered eating habits and attitudes to clinical outcomes in young adult females with type 1 diabetes

OBJECTIVE

To describe the clinical outcomes of adolescent and young adult female subjects with type 1 diabetes in relation to the disturbance of eating habits and attitudes over 8-12 years.

RESEARCH DESIGN AND METHODS

Patients were recruited from the registers of pediatric and young adult diabetes clinics (including nonattenders) and interviewed in the community. A total of 87 patients were assessed at baseline (aged 11-25 years), and 63 (72%) were reinterviewed after 8-12 years (aged 20-38 years). Eating habits and attitudes were assessed by a semistructured research diagnostic interview (Eating Disorder Examination).

RESULTS

Clinical eating disorders ascertained from the interview and/or case note review at baseline or follow-up were found in 13 subjects (14.9% [95% CI 8.2-24.2]), and an additional 7 subjects had evidence of binging or purging, bringing the total affected to 26%. Insulin misuse for weight control was reported by 31 (35.6% [25.7-46.6]) subjects. Overall outcome was poor; serious microvascular complications were common and mortality was high. There were significant relationships between disordered eating habits, insulin misuse, and microvascular complications.

CONCLUSIONS

Although the cross-sectional prevalence of clinical eating disorders in young women with diabetes is modest, the cumulative incidence of eating problems continues to increase after young adulthood, and this is strongly associated with poor physical health outcomes. The combination of an eating disorder and diabetes puts patients at high risk of mortality and morbidity. Better methods of detection and management are needed.

A comparison of the binge eating scale, questionnaire for eating and weight patterns-revised, and eating disorder examination questionnaire with instructions with the eating disorder examination in the assessment of binge eating disorder and its symptoms

OBJECTIVE

The current study assesses concordance between self-administered measures and a diagnostic standard for assessment of binge frequency and diagnosis of binge eating disorder (BED) in a sample of binge eaters.

METHOD

The Questionnaire for Eating and Weight Patterns-Revised (QEWP-R), Binge Eating Scale (BES), two items from the Eating Disorder Examination Questionnaire with Instructions (EDE-Q-I), and the Eating Disorder Examination (EDE) were administered. Participants were 157 adults volunteering for a clinical study, of whom 129 (79%) were diagnosed with BED using the EDE as the diagnostic standard.

RESULTS

In the identification of BED, the QEWP-R yielded a sensitivity value of .74 and a specificity value of .35. The BES yielded a sensitivity value of .85 and a specificity value of .20. Frequency of binge eating days and episodes on the EDE-Q-I correlated highly with the EDE (.65 and .48, respectively; p < .001).

DISCUSSION

The accuracy of diagnosis and symptomatology among self-administered questionnaires is variable. The BES and the QEWP-R performed satisfactorily as initial screens for the diagnosis of BED, but were less accurate in identifying non-BED individuals and the frequency of binge eating. The EDE-Q-I most accurately assessed the frequency of binge eating.

Assessment of eating disorders: review and recommendations for clinical use

Practitioners have come under increasing pressure to provide objective data on assessment and treatment outcome of clients. This article provides a brief summary of assessment of eating disorders for the practicing clinician, with an emphasis on well-validated assessment instruments. The critical domains that should be covered in a thorough assessment of eating disorders are reviewed, as are some shortcomings in the current assessment literature, and also discussed is which assessment instruments for the eating disorders are most useful in a clinical context. Using well-validated, standardized assessment instruments in all phases of the treatment process is a critical part of justifying a treatment plan and providing objective data on client progress and outcome.

Time course of symptom remission in eating disorders

OBJECTIVE

The study was carried out to test whether time to remission varies for different eating disorder symptoms.

METHOD

Sixty-five patients (35 anorexic patients and 30 bulimic patients) treated with psychotherapy were interviewed 2 1/2 years after initial assessment.

RESULTS

The anorexic physical symptoms remitted before the psychological symptoms of anorexia and bulimia nervosa, as did the bulimic behaviors: binging and purging. Nonpurging compensatory behavior and obsession with weight and shape were the last symptoms to remit. Differences between the anorexic and bulimic groups were found between the remission order of psychological symptoms.

DISCUSSION

In spite of different treatments and symptoms between patients, the results support the notion of a common pattern in the process of change including a long and stepwise course. The results detail a template of the course to recovery for eating disorders.

The reliability and validity of the Swedish version of the Body Shape Questionnaire

Psychometric properties of the Swedish version of the Body Shape Questionnaire (BSQ) were examined using data from three samples: (1) a sample from the general population (n= 1157), (2) a student sample (n= 124) and (3) a clinical sample (n= 90). Analyses showed that a single factor solution might be a reasonable solution as 32 of the 34 items loaded heavily on the first factor. The derived short 14-item version of the BSQ also showed a coherent structure with all the items loading on one single factor. The BSQ showed high test-retest reliability, very high internal consistency, ranging from 0.94 to 0.97, and high split-half reliability (above 0.93). Furthermore, it showed high validity by correlating highly with the body dissatisfaction subscale of the Eating Disorders Inventory (r= 0.72 and higher), and high discriminant validity. Thus, the Swedish version of the BSQ showed good concurrent and discriminant validity as well as high reliability.

Good outcome of adolescent onset anorexia nervosa after systematic treatment. Intermediate to long-term follow-up of a representative county-sample

We studied the intermediate to long-term outcome of childhood and adolescent onset anorexia nervosa (AN), in a sample that had received systematic treatment based on close cooperation between parents, paediatric department and child and adolescent psychiatry. Of 55 female AN-patients, 51 were examined 3.5-14.5 years after treatment start. The material includes all AN-patients under 18 years in one county that received inpatient treatment and almost all that received outpatient treatment, during the time period 1986-1998. Forty-two (82%) subjects had no eating disorder (ED) at follow-up, one (2%) had AN, one (2%) bulimia nervosa (BN) and seven (14%) had less severe ED (EDNOS). Except the one with BN, none had bulimic symptoms. There was no mortality. Twenty (41%) had one or more other axis-1 psychiatric diagnoses at follow-up. Depression and anxiety disorders were most frequent. Psychosocial functioning assessed by Global Assessment of Functioning (GAF) was fairly good; mean 73+/-SD14 for symptoms and mean 77+/-SD13 for functioning. Only 48% were satisfied with life, compared to 83% in a normal population sample. Our conclusion is that the eating disorder outcome was good. However, in accordance with other studies, many subjects had other psychiatric problems at follow-up.

The Eating Disorder Examination as a retrospective interview

The purpose of this study was to determine the validity of the Eating Disorder Examination 12.0D (EDE) when administered retrospectively.

METHODS

Twenty-five female patients suffering from an eating disorder [(10 with anorexia nervosa (AN), 10 with bulimia nervosa (BN), 5 with eating disorders not otherwise specified (EDNOS)] were investigated using the EDE at the time of the first referral to our outpatient ward (T1). Afterwards (mean 1.4 +/- 0.6 years later) each patient was administered again the EDE by the same assessor (T2). At this time the interviewer asked the patients to answer the questions referring to the symptoms and behaviours at the time of the first interview.

RESULTS

Test-retest correlation factors were 0.7 or greater for all subscales of the EDE (p < 0.0001) and 0.5 or greater for every single item of the EDE (p < 0.001), except for EDE 1.5 (snack after dinner) and EDE 9A.6 (maximum time free from objective bulimic episodes in the last two months).

DISCUSSION

Our results provide evidence that the EDE 12.0D is a reliable interview even when administered retrospectively, suggesting the use of this instrument for the retrospective assessment of eating disorders.

Emotional functioning in anorexia nervosa patients: adolescents compared to adults

Studies concerning eating disorder patients have revealed the presence of alexithymia, depressive, and anxiety disorders. We compared these aspects of emotional functioning in two groups of anorexia nervosa (AN) patients: adolescents vs. adults. Forty-eight adolescent anorexia nervosa patients (ADO) and 23 adult anorexia nervosa patients (ADU) completed a battery of tasks and questionnaires to measure these different aspects of emotional functioning and to control for differences of a more general cognitive nature. Both groups showed marked resemblance; both had high alexithymia scores and performed worse on emotional tasks measuring aspects of alexithymia. Furthermore, both groups showed high percentages of depressive and anxiety disorders, with the ADU group scoring only higher on specific and social phobia than the ADO group. Adult and adolescent AN patient groups do not differ substantially with respect to emotional functioning.

Disturbed eating behavior and eating disorders in preteen and early teenage girls with type 1 diabetes: a case-controlled study

OBJECTIVE

To compare the prevalence of eating disturbances in preteen and early teenage girls with type 1 diabetes to their nondiabetic peers.

RESEARCH DESIGN AND METHODS

A cross-sectional, case-controlled study of 101 girls with type 1 diabetes, ages 9-14 years, and 303 age-matched, female nondiabetic control subjects was conducted. Participants completed a Children's Eating Disorder Examination interview. Socioeconomic status, BMI, and diabetes-related variables were assessed. Groups were compared using chi(2) analyses.

RESULTS

Binge eating; the use of intense, excessive exercise for weight control; the combination of two disturbed eating-related behaviors; and subthreshold eating disorders were all more common in girls with type 1 diabetes. Metabolic control was not related to eating behavior in this study population.

CONCLUSIONS

Eating disturbances, though mostly mild, were significantly more common in preteen and early teenage girls with type 1 diabetes. Screening and prevention programs for this high-risk group should begin in the preteen years.

Assessment of eating disorder psychopathology in obese children and adolescents: interview versus self-report questionnaire

The present study compared two methods for assessing binge eating and related eating disorder psychopathology in obese children and adolescents. A comparison was made between the child version of the Eating Disorder Examination (ChEDE) and the self-report version of the interview (ChEDE-Q). A total of 139 children and adolescents (aged 10-16 years) seeking inpatient treatment for obesity completed the ChEDE questionnaire and were administered the ChEDE interview afterwards. The ChEDE and ChEDE-Q were significantly correlated for the four subscales: restraint, eating concern, weight concern and shape concern. The ChEDE-Q generated consistently higher levels of eating disorder psychopathology. There was a significant discrepancy for the assessment of a more complex feature such as binge eating. Overall, the current study found lower levels of agreement between the EDE and EDE-Q than previously reported in adult samples. It appears that children and adolescents have difficulties in identifying binge-eating episodes when they receive no detailed instruction. It is concluded that a clinical interview is necessary to identify eating disorders in obese children and that a self-report questionnaire can only be used as a screening tool. Even then, thorough clarification of the definition of the eating disorder features is needed when using a self-report questionnaire.
