[Preliminary studies of the structured diagnostic interview for personality disorders: SCID II]

The aim of the study was to compare control subjects and consultant patients with the SCID II (interview and questionnaire), then to compare clinical diagnosis with the SCID II (interview and questionnaire). The preliminary study was carried out to assess the feasibility of the procedure. This appraisal was conducted with a group of patients (n = 26) and a control group (n = 16). Only the patients were diagnosed according to DSM IV criteria. The patients and the control group completed the Mini-Mult and the SCID II (questionnaire and interview). The two groups were matched on sex, age and educational level. The two groups were discriminated on all Mini-Mult scales but one: the internalization index. The results showed that the SCID questionnaire and the SCID interview differentiate the two groups. The SCID questionnaire showed high sensitivity in the group of patients. It is a more efficient instrument to screen control subjects except one personality disorder (obsessive-compulsive). The diagnostic agreement between the clinical diagnosis and the structured interview was poor. However our results are comparable to the other studies.
