Note. Blank cells in the table indicate that data for those variables were missing from the original research reports. Under “Patient Sample,” 1 = psychiatric patients; 0 = non-patients only, or both patients and non-patients. Under “Structured Interview,” 1 = eating disorder diagnoses established via structured interview; 0 = investigators did not explicitly state that diagnoses were established via clinical interview, or investigators stated that diagnoses were established via unstructured interview or self-report questionnaire.
