[Personal identity and multiple personality].
The present study analyses the internal organization of self concepts in a woman who meets the DSM III criteria of multiple personality disorder. The aim of this single case study, was to assess the personal identity of this patient, the degree of internal coherence and the hierarchical structure of the descriptions of self and others in the frame of cognitive theories of personality. After the clinical observation, the experimental procedure is presented. It consists in asking the patient to describe her different roles or alternated personalities (N = 12), as well as the target persons of her familial and social environment (N = 8) on the basis of a preestablished list of adjectives (extracted from the 16 P.F. Cattell sphere of personality). The factorial analysis of the contingency table: traits attributed x persons described shows a Guttman like hierarchical structure. Similarities and differences between the descriptions can be ordered on a unidimensional order, the multiple roles or personalities being no more complex nor simple than the target persons. The present results have been discussed in reference to cognitive theories of personality and their utility in studying personal identity and multiple personality.
