Validation française du Big Five Inventory à 10 items (BFI-10)

Résumé

ObjectiveOur primary objective was to validate the French version of the BFI-10, an ultra-short ten-item version of the Big Five Inventory (BFI; John et al., 1991), which allows for a reasonably accurate assessment of personality in circumstances in which more in-depth assessment is not possible. In order to reach a thorough evaluation of the external validity, we also aimed to examine the bandwidth of the BFI-10 scales with reference to the study by De Young, Quilty and Peterson (2007) who distinguished between two aspects in each of the Big Five: Assertiveness and Enthusiasm for Extraversion; Compassion and Politeness for Agreeability; Orderliness and Productiveness for Conscientiousness; Withdrawal and Volatility for Negative Emotionality, and finally Openness to Aesthetics and Openness to Ideas for Open-Mindedness. Our concern with regard to bandwidth was to examine whether the BFI-10 scales have strong enough correlations with both aspects of each domain.MethodsParticipants. Data from four samples were analysed: Sample 1 comprised 2499 undergraduate students (1654 women) who completed the full BFI in university classes; Sample 2 comprised 13,306 participants (8471 women) who filled out the BFI-10 ten items online via Internet; Sample 3 comprised 143 undergraduate students (115 women) who completed the full BFI twice with a two-week interval; Sample 4 comprised 360 undergraduate students (183 women) who filled out the BFI and NEO PI-R. Instruments. The French version of the Big Five Inventory is a 45-item inventory, which measures the five broader domains of personality. The ultrashort Ten-item Big Five Inventory (BFI-10) was developed simultaneously in German and English by Rammstedt and John (2007); it comprises five two-item scales measuring the big five domains. The Neuroticism-Extraversion-Openness Personality Inventory Revised (NEO PI-R; Costa et McCrae, 1992) is a 240-item questionnaire which assesses the big five domains and 30 lower-order facets, i.e. six facets per domain. Statistical analyses. Factor structure and reliability of the five two-item scales were first investigated on samples 1 and 3. Confirmatory factor analyses (CFAs) were conducted on samples 1 and 2, and discriminant validity was assessed via comparison with the NEO PI-R (sample 4). In order to examine the bandwidth of the BFI-10 two-item scales, we studied their correlation not only with the NEO PI-R domains but also with the 30 facets.ResultsThe CFAs showed the good fit of the five-factor structure, with RMSEA = .077 (.072), CFI = .974 (.956), and SRMR = .029 (.027) in samples 1 and 2 respectively. Multigroup CFA conducted in groups 1 and 2 showed invariance across gender of factor loadings and item intercepts. Test-retest reliability was satisfactory with rs ranging from .68 (Open-Mindedness) to .86 (Extraversion and Negative Emotionality). The comparison of the two-item scales with the NEO PI-R scales showed high correlations not only with the NEO domain scales, but also with several facets: Four BFI-10 two-item scales (Extraversion, Conscientiousness, Negative Emotionality, and Open-Mindedness) were highly correlated with at least three of the six NEO facet scales in each domain. For Agreeableness, the magnitude of correlations was smaller, but the pattern of correlations was the same. All BFI-10 scales had at least moderate correlations with both aspects of each domain, with the exception of Negative Emotionality, which measured the NEO Withdrawal aspect better than Volatility.ConclusionThe French version of the BFI-10 demonstrated the expected five-factor structure, satisfactory reliability, and broad bandwidth. It could be a valuable tool for the assessment of personality in circumstances in which it is not possible to use a longer and more in-depth instrument, especially when personality is not the main focus of research but one of the variables to be controlled.
L’objectif de cette étude est de valider une adaptation française de la forme très courte du Big Five Inventory (BFI) qui comporte 10 items (BFI-10). Notre but était d’examiner en profondeur, en plus de la structure factorielle et de la fiabilité, la validité de cet instrument, afin de déterminer s’il mesure de manière adéquate les domaines de la personnalité ou seulement certains de leurs aspects. Nous avons recruté 4 échantillons différents (respectivement n = 2499, 13 306, 143 et 360 participants) pour étudier la structure factorielle, la fidélité test-retest et la validité externe du BFI-10. Les instruments utilisés étaient le BFI (échantillons 1, 3 et 4), le BFI-10 (échantillon 2) et le NEO PI-R (échantillon 4). Nous avons étudié la structure factorielle du BFI-10, la fidélité test-retest et la validité externe avec les échelles du NEO PI-R. Les analyses factorielles confirmatoires ont confirmé la pertinence de la structure en cinq facteurs, avec des indices d’ajustement satisfaisants, ainsi que l’invariance selon le sexe des coefficients de saturation et des intercepts, ce qui rend valide la comparaison des scores des femmes et des hommes. La comparaison avec le NEO PI-R montre que les échelles du BFI-10 fournissent une estimation suffisamment large des domaines. Les femmes ont des scores de Névrosisme plus élevés que les hommes (d = 0,55), alors que les différences aux autres échelles sont négligeables. Le BFI-10 présente des qualités psychométriques intéressantes qui permettent une évaluation raisonnablement fiable et valide de la personnalité dans des circonstances où l’emploi d’instruments plus longs n’est pas envisageable.
