Multicentre rating of a delusional patient with help of the AMDP scale

Abstract

A videotaped interview of a delusional patient was evaluated by 33 French, Swiss and Belgian raters. The inverse factor analysis of the raters and multivariate indexes demonstrate in this single case study that the interrater reliability depends on: a) the general training of the raters in psychopathology; b) their knowledge of the AMDP System; c) a comprehensive understanding of the psychopathology of the patient; d) AMDP concepts; e) the interview technique (this latter deficiency may be corrected by a semi-structured interview
