[Operationalization of the "locus of control" concept: translation and first validation study of the Levenson control scale (IPC: the internal powerful others and chance scale)].

This work presents the study of validation of the French version of the Internal Powerful others and Chance Scale (IPC) of Levenson. A principal components analysis was carried out on a group of 134 healthy subjects. The Cronbach alpha coefficient and the correlation between the items and the total score of each sub-scale of the IPC were calculated. Our results were discussed in comparison with others studies.
