Objective Existing measures for DSM-IV eating disorder diagnoses have notable limitations and there are important differences between DSM-IV AGIF and DSM-5 feeding and eating disorders. or Eating Disorder (USFED) to κ=0.90 for Binge Eating Disorder (BED). The EDA-5 test-retest kappa coefficient was 0.87 across diagnoses. For Study 2 clinical interview versus “app” conditions revealed a kappa of 0.83 for all eating disorder diagnoses (n=71). Across individual diagnostic categories kappas ranged from 0.56 for OSFED/USFED to 0.94 for BN. Discussion High rates of agreement were found between diagnoses by EDA-5 and the EDE and EDA-5 and clinical interviews. As this study supports the validity of the EDA-5 to generate DSM-5 eating disorders and the reliability of these diagnoses U 73122 the EDA-5 may be an option for the assessment of Anorexia Nervosa Bulimia Nervosa and BED. Additional research is needed to evaluate the utility of the EDA-5 in assessing DSM-5 feeding disorders. A number of interview-based assessment tools are available to assign DSM-IV1 eating disorder diagnoses. Commonly used measures in research studies include the Eating Disorder Examination (EDE2) and the Structured Clinical Interview for DSM-IV (SCID-IV3). However these measures have limitations. For example although the DSM-IV criteria for anorexia nervosa (AN) include disturbances in the experience of body weight or shape and a lack of recognition of U 73122 the seriousness of low excess weight (Criterion C) these features are not evaluated from the EDE4. Further diagnostic agreement using DSM-IV assessment interviews is variable. For example using the requirements explained by Landis and Koch (19775) kappa statistics for the analysis of AN are moderate for the interviewer-based EDE in comparison to self-report (κ=0.566). Moderate to substantial agreement has been U 73122 observed for AN (κ=0.68) and for feeding on disorder not otherwise specified (κ=0.60) with U 73122 higher agreement for bulimia nervosa (BN; κ=0.83) between clinician interview and SCID-IV7. Taken together these findings suggest that the current diagnostic instruments provide an incomplete U 73122 assessment of DSM-IV eating disorder criteria and have inconsistent reliability estimations across diagnoses. In addition with the publication of the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-58) the category of feeding and eating disorders has been revised. Both moderate (e.g. reducing the rate of recurrence of binge eating and/or purging actions for the analysis of BN) and major (e.g. merging feeding and eating disorders into one category; designating binge eating disorder (BED) and avoidant/restrictive food intake disorder (ARFID) as formal diagnostic groups) changes were made from earlier versions of the DSM. Given the limitations of the existing steps for DSM-IV eating disorder diagnoses and the variations between DSM-IV and DSM-5 diagnostic criteria for feeding and eating disorders fresh diagnostic assessment tools are needed. In constructing a new diagnostic instrument we elected to develop an interview-based instrument for feeding and eating disorders that targeted to reduce participant and staff burden in study settings having a focused diagnostic evaluation that did not also assess related psychopathology. Such a measure might also become helpful in non-research settings to assist in determining if an individual’s symptoms meet up with DSM-5 criteria. Therefore we produced a semi-structured interview for feeding and eating disorder analysis the Eating Disorders Assessment for DSM-5 (EDA-5). Two studies described below evaluated the initial psychometric properties of the EDA-5. Study 1 evaluated the diagnostic validity of the EDA-5 relative to the EDE the test-retest reliability of diagnoses generated from the EDA-5 and the acceptability of the measure. Study 2 used an electronic application (“app”) of the EDA-5 and examined the diagnostic validity of the EDA-5 to an unstructured clinician interview and a self-report diagnostic measure. Study 2 also examined group variations between diagnostic organizations identified from the EDA-5 on two self-report steps of eating disorder psychopathology. Study 1 Overview Study 1 was designed to: (1) compare diagnostic agreement between the EDA-5 and the EDE (2) examine the test-retest reliability of the EDA-5 and (3) evaluate the acceptability of the EDA-5 with regard to the duration and.
