Dissociation : Vol. 6, No. 1, p. 038-041 : Screening for MPD: clinical utility of the Questionnaire of Experiences of Dissociation
(Ridgeview Institute and the International Society for the Study of Multiple Personality and Dissociation, 1993-03) Dunn, Gary E.; Ryan, Joseph J.; Paolo, Anthony M.; Miller, Darrell
The major purpose of this study was to determine the effectiveness of the Questionnaire of Experiences of Dissociation (QED) as a screening instrument for the diagnosis of multiple personality disorder (MPD). The QED was administered to 18 patients with MPD, 18 control subjects, 18 alcoholics, and 15 patients diagnosed with both PTSD and a substance abuse disorder. Using a cut-off score of 15, the QED correctly identified all MPD patients as needing further screening. None of the control subjects, and only one of the alcoholics, were incorrectly identified as requiring further evaluation. These preliminary findings suggest that the QED has good clinical utility as a screening tool for the identification of individuals who are afflicted with multiple personality disorder.
