The Relationship Between the Models of Sport Commitment and Self-Determination among Adolescent Athletes

This study examined the relationship between the Sport Commitment Model and the Self-Determination Theory. The participants were 214 adolescent athletes who completed the Hungarian version of the Sport Commitment Questionnaire-2 and the Hungarian version of the Sport Motivation Scale. Several commitment sources predicted SMS scores as well. Amotivation was predicted by the obligatory reason for commitment such as Personal Investment-Loss and Other Priorities. External Regulation was predicted by Social factors of commitment. Introjected Regulation was determined by Desire to Excel-Mastery and Personal Investment-Loss. Identified Regulation was explained by Desire to Excel-Mastery, Valuable Opportunities, and Personal Investment-Loss. Integrated Regulation was explained with Valuable Opportunities, Desire to Excel-Mastery, Personal Investment-Loss and Social Support-Informal. The Intrinsic Motivation subscale was significantly predicted by Desire to Excel-Mastery, Personal Investment-Loss, Sport Enjoyment and Social Support-Informal. As we see the types of commitment showed a clear association with SMS, however the commitment sources showed a complex relationship with self-determination, thus it is hard to separate them on the Self-determination continuum.
