title: [Factor analysis of the French revision of the AMDP rating scales. Results of an international study of 388 cases].
abstract: A total of 388 patients from 10 Belgian and French Centers were evaluated with the 1981 revision of the psychopathological and somatic scales of the AMDP System. Principal components factor analyses indicate that the somatic items contribute little to the structure. A 10-factors solution of the psychopathological items generate the following factors after orthogonal rotation: Obsessions-Phobias, Dramatization, Anxiety, Depression, Retardation, Organicity, Dissociation, Delusions, Mania, Dysphoria. This structure is similar to the analyses of the previous German edition except for Anxiety (due to additional French items) and Dramatization (which replaces the German factor on Hypochondriasis). The correlations between raw factor scores and item scores of the BPRS and of a similar AMDP-derived scale contribute to the validation of the AMDP factors and to the justification of a 13-item AMDP Syndromic Scale.
