A cross-cultural study of the higher-order structures underlying personality disorders in French-speaking Africa and Switzerland.

Most studies about the higher-order dimensions to be considered in order to parsimoniously describe Personality Disorders (PDs) have identified between two and four factors but there is still no consensus about their exact number. In this context, the cultural stability of these structures might be a criterion to be considered. The aim of this study was to identify stable higher-order structures of PD traits in a French-speaking African and Swiss sample (N = 2,711).

Personality disorders and the five-factor model among French speakers in Africa and Europe.

Objective: To describe the relation between personality disorders (PDs) and the Five-Factor Model (FFM)--a dimensional model describing normal personality traits known for its invariance across cultures--in 2 different cultural settings. Several authors have suggested that PDs may be more accurately described using a dimensional model instead of a categorical one.

Method: Subjects from 9 French-speaking African countries (n = 2014) and from Switzerland (n = 697) completed both the French version of the International Personality Disorder Examination screening questionnaire, assessing the 10 DSM-IV PDs, and the French version of the Revised NEO Personality Inventory, assessing the 5 domains and 30 facets of the FFM.
