Development and validation of the Eating Disorder Diagnostic Scale: A brief self-report measure of anorexia, bulimia, and binge-eating disorder.

Abstract

This article describes the development and validation of a brief self-report scale for diagnosing anorexia nervosa, bulimia nervosa, and binge-eating disorder. Study 1 used a panel of eating-disorder experts and provided evidence for the content validity of this scale. Study 2 used data from female participants with and without eating disorders (N = 367) and suggested that the diagnoses from this scale possessed temporal reliability (mean K -.80) and criterion validity (with interview diagnoses; mean K = .83). In support of convergent validity, individuals with eating disorders identified by this scale showed elevations on validated measures of eating disturbances. The overall symptom composite also showed test-retest reliability (r = .87), internal consistency (mean a -.89), and convergent validity with extant eating-pathology scales. Results implied that this scale was reliable and valid in this investigation and that it may be useful for clinical and research applications.It has been estimated that 10% of female individuals in western countries will suffer from a diagnosable eating disorder (American Psychiatric Association [APA], 1994), making it one of the more prevalent psychiatric problems faced by women. Anorexia nervosa is characterized by (a) extreme emaciation; (b) intense fear of gaining weight or becoming fat despite a low body weight; (c) disturbed perception of weight and shape, an undue influence of weight or shape on self-evaluation, or a denial of the seriousness of the low body weight; and (d) amenorrhea (APA, 1994). This disorder has a lifetime prevalence of almost 1% among females, is refractory to treatment, shows a chronic course, results in serious medical complications, and is associated with psychiatric comorbidity such as mood, anxiety, and personality disorders (Wilson, Heffernan, & Black, 1996).Bulimia nervosa involves (a) recurrent episodes of uncontrollable consumption of large amounts of food, (b) compensatory

Associations Between Fear of Negative Evaluation and Eating Pathology During Intervention and 12-Month Follow-up

“…The Eating Disorder Diagnostic Scale (EDDS; Stice, Telch, & Rizvi, 2000) was used to assess DSM-IV ED symptoms. The EDDS has shown good internal consistency (α= .89), 1-week retest reliability ( r = .87), criterion validity ( K = .78), and sensitivity to detecting intervention effects (Stice et al, 2004; Stice, Presnell, et al, 2007).…”

Explaining the role of binge eating behaviour in weight loss post bariatric surgery

“…Binge eating was assessed with the Eating Disorders Diagnostic Scale (EDDS; Stice, Telch & Rizvi, 2000). The EDDS is a 22-item self-report scale intended to assess the DSM-IV (American Psychiatric Association, 1994) criteria for anorexia nervosa, bulimia nervosa and binge eating disorder (Stice, Telch & Rizvi, 2000;Stice, Fisher & Martinez, 2004).…”

“…The EDDS is a 22-item self-report scale intended to assess the DSM-IV (American Psychiatric Association, 1994) criteria for anorexia nervosa, bulimia nervosa and binge eating disorder (Stice, Telch & Rizvi, 2000;Stice, Fisher & Martinez, 2004). This measure is well validated and reliable, exhibiting validity with interview-based diagnoses, convergent validity with risk factors for eating pathology, and internal consistency (Stice et al, 2000). In order to make a diagnosis of DSM-IV binge eating disorder, items 5-18 were used from the EDDS.…”
