DAPP-BQ: factor structure in French Canadians

Area of Science:

• Psychology
• Psychiatry
• Cross-cultural psychology

Background:

• Personality traits are implicated in various clinical and behavioral outcomes.
• Understanding the cross-cultural and sexual applicability of personality traits is crucial for accurate assessment and diagnosis.
• The Diagnostic Assessment of Personality Pathology-Basic Questionnaire (DAPP-BQ) is a key instrument for measuring personality pathology.

Purpose of the Study:

• To examine the structural equivalence of broad personality traits using the DAPP-BQ in a French Canadian sample.
• To investigate sex-based differences in item endorsement, scale reliabilities, and factor solutions of the DAPP-BQ.
• To assess the cross-cultural and sociodemographic stability of personality trait structures.

Main Methods:

• Utilized a well-characterized, longitudinal sample of young French Canadians.
• Administered the Diagnostic Assessment of Personality Pathology-Basic Questionnaire (DAPP-BQ).
• Conducted analyses on structural equivalence, sex-based patterns, item endorsement, scale reliabilities, and factor solutions.

Main Results:

• The four-factor solution of the DAPP-BQ closely resembled the structure found in British Columbians, particularly Factors I-III.
• Factor IV was defined by compulsivity and rejection, differing from the original study's inclusion of passive aggression.
• Observed significant sex-based differences in item endorsement and personality trait scores.

Conclusions:

• Broad DAPP-BQ personality traits demonstrate structural stability across sociodemographic and cultural contexts.
• The findings support the cross-cultural applicability of the DAPP-BQ personality structure.
• Acknowledged subtle sex-based differences in personality trait expression warranting further investigation.
