The present study examined the prevalence of eating disorders in a male representative random sample in Tyrol. The data were collected by telephone. Of the 1000 men, 8 (0.8%) met the DSM-IV diagnostic criteria for binge eating disorder. An additional 42 subjects (4.2%) exhibited a partial binge eating syndrome. These two otherwise widely identical groups of binge eaters were separated only by the DSM-IV frequency criterion. Five subjects (0.5%) met the DSM-IV criteria for the diagnosis of bulimia nervosa, and 94 men (9.4%) reported recurrent overeating. Men with any eating disorder were mostly overweight or obese. The findings show that there is a significant difference in eating disorders between men and women, but certain eating disorders are frequent not only in women but also in men.

The aims of this study were, firstly, to examine the factor structure of single items from several self-report methods used to measure eating disorder symptoms, and secondly, in search for a short assessment instrument to reduce the number of items within each factor. Factor analyses were employed to identify and confirm the constructs measured by a total of sixty items drawn from these assessment methods. In phase one, 508 secondary school pupils were recruited as subjects, and principal factor analysis identified three factors; body concern, dieting, and loss of control over eating. Twenty-nine items were retained, and in phase two subjected to a second data collection among 4129 secondary school pupils. Confirmatory factor analysis was employed to cross-validate the factor structure from phase one. The three-factor structure was confirmed satisfactorily for boys, but not for girls aged 12-14 years. For girls aged 14-16 years, it was confirmed when a number of items were omitted. The findings are discussed in relation to restraint theory and the continuum hypothesis.

This study investigated the association of dietary restraint and disinhibition with self-reported and actual eating behavior, body mass, and hunger. A sample of 124 women were categorized into one of four groups based upon high and low scores on measures of Dietary Restraint and Disinhibition using the Three Factor Eating Questionnaire. Half of the participants in each group consumed a high sugar/high fat chocolate pudding as a dietary preload. All participants were given a meal comprised of a standard macaroni and beef product. The interaction of Dietary Restraint and Disinhibition was related to differences in body mass. The Dietary Restraint factor was related to self-reported pathological eating behavior and influenced both perceived hunger and subjective hunger ratings. However, actual eating behavior measured by calories consumed and rate of intake was unrelated to the Dietary Restraint factor. Disinhibition was associated with excessive eating, an increased rate of eating, self-reports of eating disorder symptomatology, and perceived hunger. Hence, actual eating behavior was significantly influenced by the ingestive motivational factor, Disinhibition, but not by the cognitive factor, Dietary Restraint. These data also suggest that the Disinhibition construct is measuring overeating rather than disinhibited eating which implies the disruption of Dietary Restraint.

A cross-sectional observational study was used to investigate the reported association between polycystic ovarian syndrome and bulimia nervosa in a group of young, post-menarcheal women in the normal population. Volunteers aged 18-25 years were recruited from two universities and two general practice surgeries in Oxford. A total of 230 women completed an interviewer-based eating disorder examination, which was used to diagnose bulimia nervosa and its variants, and to assess eating behaviour. Transabdominal ultrasound was used to diagnose the presence or absence of polycystic ovaries. Symptoms of polycystic ovarian syndrome were assessed using menstrual history, anthropometric measurements, clinical observation of acne and hirsutism, and biochemical analysis of a fasting blood sample. A total of 30% of all participants described episodes of overeating and 4% had used extreme methods of weight control. Two women were diagnosed with bulimia nervosa, and five women with binge-eating disorder; however, these diagnoses were not associated with polycystic ovaries. Scores for dieting and overall eating disorder symptoms in the polycystic ovary groups were not significantly higher than those for women with normal ovaries, and therefore the suggestion that polycystic ovaries predispose towards the development of eating disorders is not supported by this study.

The authors compared 3 methods for assessing the features of eating disorders in patients with binge eating disorder (BED). Participants were administered the Eating Disorder Examination (EDE) interview and completed the EDE Questionnaire (EDE-Q) at baseline. Participants prospectively self-monitored their eating behaviors daily for 4 weeks and then completed another EDE-Q. The EDE and the EDE-Q were significantly correlated on frequencies of objective bulimic episodes (binge eating) and on the Dietary Restraint, Eating Concern, Weight Concern, and Shape Concern subscales. Mean differences in the EDE and EDE-Q frequencies of objective bulimic episodes were not significant, but scores on the 4 subscales differed significantly, with the EDE-Q yielding higher scores. At 4 weeks, the EDE-Q retrospective 28-day assessment was significantly correlated with the prospective daily self-monitoring records for frequency of objective bulimic episodes, and the mean difference between methods was not significant. The EDE-Q and self-monitoring findings for subjective bulimic episodes and objective overeating differed significantly. Thus, in patients with BED, the 3 assessment methods showed some acceptable convergence, most notably for objective bulimic episodes.

Project GRAD (Graduate Ready for Activity Daily) was a randomized controlled study to teach university seniors behavioral skills necessary for increasing and/or maintaining physical activity habits in preparation for the transition to working adult roles after graduation. This study examines the secondary effects of this intervention on body image concerns among college-aged men and women. Three hundred thirty-eight undergraduates (54%female, Mage = 24years, SD = 1.95; MBody Mass Index = 24.26, SD = 4.0) were studied. The sample was 61/% Anglo, 16% Latino, 16% Asian/Pacific Islander, 4% African American, and 3% Native American/Other Body image concerns were assessed at pre- and posttreatment using 2 subscales of the Eating Disorder Inventory: Drive for Thinness and Body Dissatisfaction. Because the latter concentrates on body parts typically associated with female concerns (e.g., thighs, hips, buttocks), a parallel scale was developed to target body parts that may be of more concern to men (e.g., legs, shoulders, arms, stomach). Results indicated that compared to the control group, women in the intervention showed a significant increase in drive for thinness without any changes in body dissatisfaction. For men, there were no significant changes in drive for thinness or body dissatisfaction. These results suggest that physical activity interventions may have some negative consequences of increasing concerns about thinness in women. This negative effect occurred despite intervention content designed to prevent concern over eating, dieting, and the importance of weight. Health promotion studies should include assessments of potential negative side effects.

As science and medicine enter the new millennium, the influences of genetics and neurochemistry as high-risk determinants in the etiology and development of eating disorders are increasingly manifest in professional literature. Eating disorders are now recognized as major medical and psychiatric problems affecting millions throughout the world. Psychoeducational, cognitive, behavioral, and psychopharmacologic treatments form the basis of most interventions which, for the most part, tend to view the eating disorder as a symptom of underlying psychopathology. The Israel Counseling and Treatment Center of the North has been treating eating disorders as addictive disease by applying the twelve step program of the Anonymous Fellowships as an adjunct to counseling and treatment for those who suffer from compulsive overeating and bulimia. Following the ongoing program of interventions with adults, a counseling group for adolescent females was co-facilitated under the supervision of the author. A co-therapist, in recovery from bulimia and comulsive overeating, uses the twelve step philosophy and served as a role model in this group intervention. Another sample of adolescent females was offered individual counseling adhering to the same addiction treatment approach. Success rates were operationally defined and measured by weight loss in the obese population and the cessation of purging behaviors among bulimic subjects for a six-month period. The two adolescent treatment samples had success rates of 62% and 33% respectively. A higher success rate of 71% was observed with adult bulimic females who participated in group counseling. A mean weight loss of 3.9 kg for the small sample of adolescents and a 9.7 kg. mean weight loss for obese adults in treatment was reported. The theoretical basis of the addiction treatment paradigm for eating disorders is presented. Results and problems encountered specific to treating the adolescent population are discussed.

Restrained eaters have repeatedly been found to overeat following a preload, which phenomenon is called the disinhibition effect. Remarkably, the disinhibition effect is only found when the restraint scale (RS) is used, and never when other measures of restraint, like the three-factor eating questionnaire (TFEQ) or the Dutch eating behavior questionnaire (DEBQ) are applied. Recent research has shown that tendency toward overeating appears to be a better predictor of food consumption than dietary restraint. The present study examines the predictive value of preload, tendency toward overeating and dietary restraint. An experiment was carried out with 209 female participants with the aim to evaluate whether the results of the study [Int J Eating Disorders 28 (2000) 333] are robust. In addition to the RS, the TFEQ and DEBQ were used to measure restraint and tendency toward overeating. Again, no disinhibition effect occurred, confirming the results of the previous study. Restraint, as measured by the three questionnaires, was not related to food consumption. In contrast, tendency toward overeating was significantly related to food consumption. Restraint theory's contentions that dieting leads to overeating might be valid for only some dieters, namely those with a high tendency toward overeating.

The diagnostic concept of binge eating disorder (BED) was introduced in response to the clinical observation of Stunkard (1959) that some people with obesity have recurrent episodes of binge eating. We suggest that the DSM-IV concept of BED has resulted in the recruitment of heterogeneous research samples, amongst which are some people with BED, as described by Stunkard, some with bulimia nervosa, some with other types of eating disorder, and some with no eating disorder. We consider the difficulties distinguishing BED from other forms of overeating, especially in patients with obesity, and from nonpurging bulimia nervosa. We propose revised diagnostic criteria for BED and bulimia nervosa that are designed to minimize these problems.

The aim of this follow-up study was to evaluate the longer-term effectiveness of guided self-care for bulimia nervosa. In the original trial, 62 patients with DSM-III-R bulimia nervosa were randomly assigned to: a) a self-care manual plus eight fortnightly sessions of cognitive behavioural therapy (guided self-change); or b) 16 weekly sessions of cognitive behavioural therapy (CBT). Twenty-eight of these patients (45% of the original cohort) were involved in this follow-up study based on personal interviews by experts and self-rated instruments; the majority of the others could not be traced, but their pre- and post-treatment variables were not different from those of the follow-up patients. After an average follow-up of 54.2 months (SD 5.8), significant improvements were achieved or maintained in both groups in terms of the main outcome measures: eating disorder symptoms based on expert ratings (Eating Disorder Examination sub-scores for overeating, vomiting, dietary restraint, and shape and weight concerns), self report (Bulimic Investigatory Test Edinburgh), and a global five-point severity scale. There was also an improvement in the subsidiary outcome variables: Beck's Depression Inventory, the Self-concept Questionnaire, and knowledge of nutrition, weight and shape. During the week before the follow-up examination, 66.7% of the patients in the guided self-change group and 61.5% of those in the CBT group had not binged, vomited or abused laxatives. Guided self-change incorporating a self-care manual is an approach that can be as effective as standard cognitive behavioural therapy in the long-term, and can reduce the amount of therapist contact required.
