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.

    • "As we have not found later validation studies for the EDS-5, the EDE-S and the RiBED, their screening properties are unsettled. The EDI discriminates reliably between patients and healthy controls, and to some degree between patient groups [3,33343536. However, the EDI subscales have shown mixed results in several screening trials. "

    ABSTRACT: Objective: The Eating Disorder Inventory (EDI) is used worldwide in research and treatment of eating disorders (EDs). Using the latest version (EDI-3: 91 items), we extracted the best screening items for a diagnosis of anorexia (AN) and bulimia (BN) nervosa. Method: A patient sample of 561 women was recruited from an ED treatment centre in Denmark, and a comparison group of 878 women was randomly selected from the general population. An ED diagnosis was determined according to the Eating Disorder Examination Interview, yielding 84 AN and 202 BN patients. Results: Only two EDI items (Cronbach's α = .79) were needed to achieve a superior screening capability of BN (sensitivity = .94, specificity = .94). An adequate screening of AN was possible by using three items (α = .71; sensitivity = .91, specificity = .86). Discussion: The present study provides an even more economical and reliable screening of AN and BN compared with existing screening instruments. Implications for DSM-5 are also discussed.

    • "The EDI-2 includes 91 items with higher scores indicating more disturbances in eating-or related behaviors. The EDI-2, Swedish version, has an internal consistency above 0.70 for most subscales [27] and possesses adequate test–retest reliability and predictive validity [28]. Three subscales measure ED symptoms and form a Symptom Index while eight subscales measure personality factors and form a Personality Index [24]. "

    ABSTRACT: Cognitive behavioral therapy-based guided self-help (CBT-GSH) via the Internet has been shown to be effective in the treatment of bulimia nervosa (BN) and similar eating disorders (EDs), but it is rarely offered, and little is known about the effects, in clinical settings. The present study investigated the effects of a bibliotherapy-based CBT-GSH with Internet support in a clinical setting. Participants were 48 adult outpatients who were recruited without randomization from a specialized ED clinic, diagnosed with BN or similar eating disorder. Forty-eight patients in an intensive day patient program (DPP) were used as comparison group. The Eating Disorder Examination Questionnaire (EDE-Q) and the Eating Disorder Inventory 2 measured pre- and post treatment symptoms. Results showed that both groups attained significant improvements in core- as well as related ED symptoms in both instruments. As expected, treatment effects were larger in the more intensive DPP. Nonetheless, bibliotherapy CBT-GSH appears to be a cost-effective treatment that represents a new way to provide more CBT in clinical settings.

    • "The ROC-analyses support the success of this purpose in the sense that the subscale interoceptive deficits is the best predictor across all diagnostic groups, followed by low self-esteem and personal alienation. Previous studies have also found interoceptive awareness along with the three eating disorder specific subscales to discriminate between eating disorder patients and psychiatric controls (Nevonen et al. 2006; Schoemaker et al. 1997). Also, interoceptive issues are related to other psychological constructs of eating disorders like depression, perfectionism, and self directiveness (Fassino et al. 2004). "

    ABSTRACT: The Eating Disorder Inventory (EDI) is used worldwide in research and clinical work. The 3(rd) version (EDI-3) has been used in recent research, yet without any independent testing of its psychometric properties. The aim of the present study was twofold: 1) to establish national norms and to compare them with the US and international norms, and 2) to examine the factor structure, the internal consistency, the sensitivity and the specificity of subscale scores. Participants were Danish adult female patients (N = 561) from a specialist treatment centre and a control group (N = 878) was women selected from the Danish Civil Registration system. Small but significant differences were found between Danish and international, as well as US norms. Overall, the factor structure was confirmed, the internal consistency of the subscales was satisfactory, the discriminative validity was good, and sensitivity and specificity were excellent. The implications from these results are discussed.
