This article describes the identification of a 10-item set of the Structured Clinical Interview for DSM-IV Personality Disorders (SCID-II) items, which proved to be effective as a self-report assessment instrument in screening personality disorders. The item selection was based on the retrospective analyses of 495 SCID-II interviews. The psychometric properties were studied in a prospective validation study in a random sample of Dutch adult psychiatric outpatients, using the SCID-II interview as the gold standard. First, all patients completed the short questionnaire. One week later, they were interviewed with the full SCID-II. After another week, the short questionnaire was readministered. According to the scores obtained with the full SCID-II, 97 patients (50%) had a personality disorder. The set of 10 SCID-II items correctly classified 78% of all participants. The sensitivity, specificity, and positive and negative power were 0.78, 0.78, 0.78, and 0.78, respectively. The results based on the retrospectively obtained data were rather similar to those obtained in the prospective validation study. Therefore, it is concluded that the set of 10 SCID-II items can be useful as a quick self-report personality disorder screen in a population of psychiatric outpatients.
