Résumé
This thesis intends to evaluate the influence exerted by the five personality dimensions of the five factors model (McCrae et Costa, 1985; 1987) on the attitudinal and behavioral consequences of a behavioral commitment, in the context of student nutrition. A first study has been conducted with 167 students with a view to evaluate the efficacy of a commitment procedure, and notably by the public pattern of this technique, as a function of these five dimensions. This study highlight a weak and limited impact of the five dimensions of personality on the studied changes: notably, it appears that extraversion influences the efficacy of private commitment to induce attitudinal changes in the long term. The second and third studies have been conducted with a population of 186 and 268 students, with a view to put to the test the influence exerted by extraversion in relation to the effects of public commitment procedure. If the second study fails to highlight such an influence, it emerges from the third study that the modulation exerted by extraversion is only found on a behavioral dimension annex to the eating changes. These three studies reveal besides that behavioral commitment fails to induce eating and attitudinal changes upper to those aroused by a non-commitment procedure. These results are discussed from the angle of the difficulty of the eating change and of the possible moderation, due to this difficulty, of the effects exerted by personality on the commitment efficiency.
