ABSTRACT The aim of the current study was to validate the Eating Disorders Inventory 2 (EDI-2) in a Swedish population by investigating how it discriminates between three female samples aged 18 to 50 years: patients with eating disorders (n = 978), psychiatric outpatients (n = 106) and normal controls (n = 602), as well as between different eating disorder diagnoses. The internal consistency of the EDI-2 was above 0.70 for most subscales. The EDI-2 discriminated well between patients with eating disorders and normal controls on all subscales. On the symptom-related subscales, eating disorder patients scored highest followed by psychiatric controls and normals. All subscales except Perfectionism, Interoceptive awareness and Asceticism discriminated eating disorder patients and psychiatric controls. Bulimia patients scored higher than anorexics on the symptom subscales. It is concluded that the EDI-2 discriminates well between eating disorder patients and both psychiatric and normal controls.

    ABSTRACT: Objectives The current study sought to compare different features of unhealthy exercise on associations with disordered eating and their ability to identify individuals with eating disorders. A secondary aim of the study was to compare prevalence and overlap of different aspects of unhealthy exercise and potential differences in their gender distribution. Design Cross-sectional epidemiological study. Methods A community-based sample of men (n = 592) and women (n = 1468) completed surveys of health and eating patterns, including questions regarding exercise habits and eating disorder symptoms. Results Compulsive and compensatory features of exercise were the best predictors of disordered eating and eating disorder diagnoses compared to exercise that was excessive in quantity. Further, compulsive and compensatory aspects of unhealthy exercise represented overlapping, yet distinct qualities in both men and women. Conclusions Including the compulsive quality among the defining features of unhealthy exercise may improve identification of eating disorders, particularly in men. Results suggest that the compensatory aspect of unhealthy exercise is not adequately captured by the compulsive aspect of unhealthy exercise. Thus, interventions that target unhealthy exercise behaviors among high-risk individuals, such as athletes, may benefit from addressing both the compulsive and compensatory aspects of unhealthy exercise. Future prospective longitudinal studies will aid in determining the direction of the association between these features of unhealthy exercise and the onset of eating pathology.

    ABSTRACT: Background: The Eating Disorder Inventory-3 (EDI-3) is designed to assess eating disorder psychopathology and the associated psychological symptoms. The instrument has been revised and has not yet been validated for Swedish conditions in its current form. Aims: The aim of this study was to investigate the validity and reliability of this inventory and present national norms for Swedish females. Methods: Data from patients with eating disorders (n = 292), psychiatric outpatients (n = 140) and normal controls (n = 648), all females, were used to study the internal consistency, the discriminative ability, and the sensitivity and specificity of the inventory using preliminary cut-offs for each subscale and diagnosis separately. Swedish norms were compared with those from Denmark, USA, Canada, Europe and Australian samples. Results: The reliability was acceptable for all subscales except Asceticism among normal controls. Analysis of variance showed that the EDI-3 discriminates significantly between eating disorders and normal controls. Anorexia nervosa was significantly discriminated from bulimia nervosa and eating disorder not otherwise specified on the Eating Disorder Risk Scales. Swedish patients scored significantly lower than patients from other countries on the majority of the subscales. Drive for Thinness is the second best predictor for an eating disorder. The best predictor for anorexia nervosa was Interoceptive Deficits and Bulimia for the other diagnoses. Conclusions/clinical implications: The EDI-3 is valid for use with Swedish patients as a clinical assessment tool for the treatment planning and evaluation of patients with eating-related problems. However, it still exist some uncertainty regarding its use as a screening tool.
