Abstract
The standard diagnostic system in the United States, the Diagnostic and Statistical Manual III-Revised, has recently been revised (i.e., DSM-IV) to include recent research and clinical advances that have enabled further specification of the existing diagnostic criteria. One set of diagnostic criteria that is representative of this increased specification are the criteria for the eating disorders. The expansion of these criteria in the recent publication of DSM-IV creates a need for the development of a structured interview that would enable differential diagnosis among these diagnostic categories. Thus, the purpose of the current study was to develop and evaluate the psychometric properties of a semi-structured diagnostic interview for DSM-IV eating disorder diagnoses. The Interview for the Diagnosis of Eating Disorders-IV (IDED-IV) was developed for this purpose. The study was conducted in three phases. Phase I involved the development of the IDED-IV which involved the application of DSM-IV criteria and changes made to the content and format of an earlier version of the IDED (i.e., IDED-III). Phase II involved examination of the reliability of the IDED-IV. High levels of internal consistency and interrater reliability for diagnosis were found. Adequate to high interrater reliability was found for the individual ratings within the IDED-IV Subscales. Phase III focused on establishing the convergent and discriminant validity of the IDED-IV. The IDED-IV Subscales were found to be related to each other and to self-report measures of eating disorder symptoms. In addition, significant differences between clinical and control groups identified by the IDED-IV were also found on measures of related and unrelated constructs. Thus, the convergent and discriminant validity of the IDED-IV was supported.
