EVIDENCE ON THE PRIMARY DIMENSIONS OF THE 16PF5 FRENCH FORM

The last adaptation of the 16PF inventory results in the 16PF 5th edit ion by R.B. Cattell, A.K.S. Cattell, & H.E.P Cattell (Conn & Rieke, 19 94). This paper reports results concerning construct validity (factori al structure) and internal consistency (Cronbach's alpha) of the 15 pr imary personality dimensions assessed by the French adaptation of the 16PF 5 inventory. Construct validity of primary dimensions was tested at the item level by a multiple group centroid confirmatory analysis ( n = 1000). Results show a good fit between hypothetical and extracted factor structure. The stability of the factor structure of these prima ry dimensions was tested by comparison of two factor structures extrac ted on two subsamples (2 x 500) derived from this total sample. Factor similarity tested by Pearson factor similarity coefficient is good (0 .879). These results provide confidence for the capacity of this Frenc h adaptation to assess the 15 personality primaries (B scale was exclu ded) described by R.B. Cattell. Concerning internal consistency, 10 sc ales reach the 0.70 Cronbach's alpha value considered as a minimal val ue for individual assessment. A complementary test shows that tile mul tiple group confirmatory method used in this study is nor flawed as ar e Procrustes solutions.
