Introduction:
The Big Five, or the Five-Factor Model (FFM) of personality, is the dominant model in trait psychology. Instruments to assess personality traits are usually long and not available in French. The Mini-International Personality Item Pool (Mini-IPIP) is a brief measure evaluating personality traits according to the Big Five model with promising psychometric properties.
Objective:
The main purposes of this study were to develop and validate a French adaptation of the Mini-International Personality Item Pool.
Method:
In Study 1, adaptation procedures that led to the translation of the French version as well as steps to maximize equivalence are described, in addition to internal consistency, temporal stability, and factor structure within a sample of 139 participants. In study 2, confirmatory factor analysis was carried out with a sample of 1308 participants, and convergent validity was explored with several pertinent constructs.
Results:
Internal consistency and test-retest correlations over a four-week period suggest adequate reliability, with coefficients respectively ranging from .64 to .81 and .74 to .89. Exploratory factor analysis suggested a sharply delineated structure. In Study 2, confirmatory factor analyzes revealed a five-factor solution consistent with the Big Five model, and convergent validity with several constructs was detailed.
Conclusion:
Overall, results pointed to a satisfactory equivalence between the original and the adapted instrument. The satisfactory indices of reliability and validity of the Mini-IPIP warrant the use of the French adaptation of the Mini-IPIP. |
