MOTIVATION AUTODETERMINÉE ET PERCEPTIONS DE CONFLIT ET D'INSTRUMENTALITÉ LIÉES AU RÔLE DE PRATIQUANT SPORTIF : RELATIONS ET INFLUENCE SUR L'ENGAGEMENT ET LE DÉSENGAGEMENT SPORTIF

Abstract : Competing activities and the lack of time constitute some of the most important reasons invoked to justify sport dropout or the absence of regular physical activity among youth and adults. This doctoral dissertation aims at enriching a motivational model of sport participation based on self-determination theory (Ryan & Deci, 2002), by integrating the perceived conflict or instrumentality relative to the athlete's role. A research program comprising 5 studies and in which more than 2500 participants were involved, was conducted. Study 1 compared young athletes and former athletes and confirmed the positive link between perceived conflict and sport dropout, and the negative association between conflict and self-determined motivation toward sport. Studies 2 to 4 adopted a longitudinal design lasting from 6 months to 3 years, in order to investigate the antecedents of perceived conflict and instrumentality, their evolution during adolescence, and their impact on subsequent sport involvement. Results show that contextual self-determined motivation usually predicts negatively the level of conflict, and positively the level of instrumentality associated to the athlete's role. High levels of conflict and low levels of instrumentality were found to lead to a decrease of sport participation with time. Finally the experimental design of study 5 brought some support to the hypothesis of a causal relationship between self-determined motivation and conflict
