DAPP-BQ: factor structure in French Canadians.
Personality traits may be involved in predisposition to a range of clinical and behavioral phenotypes. Given their importance, it is necessary to establish the extent to which different levels of personality traits are applicable to and reproducible across cultures and sexes. In a well-characterized, longitudinal sample of young French Canadians, we examined structural equivalence of broad personality traits using the Diagnostic Assessment of Personality Pathology-Basic Questionnaire (DAPP-BQ). We also investigated sex-based patterns of item-endorsement, scale reliabilities, and factor solutions. Our four-factor solution closely resembles the structure reported in the source population of British Columbians, especially in terms of Factors I through III. In contrast to the original study, however, together with compulsivity, rejection rather than passive aggression, defined Factor IV. We, furthermore, observed sex-based differences in item endorsement and both broad and narrow personality trait scores. Subtle differences notwithstanding, our results offer additional evidence for structural stability of broad DAPP-BQ personality traits across sociodemographic and cultural contexts.
