Predictors and outcomes of core and peripheral sport motivation profiles: A person-centered study.

While previous studies highlighted the importance of the different motivations for doing sports as proposed by self-determination theory, less emphasis has been put on the simultaneous presence of multiple motivations within the same individual. Therefore, the present study aimed to investigate the complex interaction of sport motivations and to identify core (common) and peripheral (uncommon) profiles of people engaged in sports based on a combination of motivations. To achieve this goal, latent profile analysis, a person-centered approach, was performed on responses from 506 participants engaged in sports. For better understanding the extracted profiles, basic psychological need fulfillment was included as profile predictor, while subjective vitality and various engagement-related indicators as outcomes. Four core and peripheral profiles were identified: Moderately Motivated, Highly Motivated, Amotivated, and Poorly Motivated. Contrary to theory, introjected regulation clustered more closely with self-determined motivations. Profile membership was significantly predicted by global need fulfillment, autonomy satisfaction as well as, to a smaller extent, autonomy, relatedness, and competence frustration. The four profiles differed along vitality and some, but not all, engagement-related outcomes.
