Passion, Motivation, and Subjective Well-Being in Sport for People with Disabilities.

Considering the absence of research testing the entire sequence of passion, behavioral regulation, and subjective well-being (SWB), this study aimed to analyze the hypothetical causal relationships between the variables of a model that integrates the Dualistic Passion Model (DMP) and Self-Determination Theory (SDT) in order to understand the impact of harmonious passion (HP) and obsessive passion (OP) and the regulation of motivation on the SWB of elite athletes with disability. This study includes 143 elite athletes from national adapted sports (36 female; 107 male) aged between 15 and 59 (M = 29.21; SD = 10.45). Weekly training sessions ranged from 1 to 12 (M = 4.52; SD = 2.71), and the years of competitive practice ranged from 1 to 28 (M = 5.55; SD = 6.98). Data were collected using valid and reliable questionnaires for the study population and analyzed using structural equation analysis. The following results were identified: a positive and a significant effect between OP and self-determination motivation (SDM); a positive but not a significant effect between OP and non-self-determination motivation (NSDM); a significant effect between SDM and SWL and SDM and positive affect (PA); and, finally, a positive but non-significant effect between SDM and negative affect (NA). In contrast, there is a positive and significant effect between HP and SDM; a negative and significant effect between HP and NSDM; a positive but non-significant effect between NSDM and SWL; a negative and significant effect between NSDM and PA; and, finally, a positive and significant effect between NSDM and NA. The perception of passion regarding sport can be a positive predictor of SDM, which, in turn, can influence levels of SWB, both from a cognitive point of view (SWL) and from an emotional point of view (PA). This reinforces the positive effect of the self-determination behavior in adapted sport on SWB and its contribution to health and quality of life in people with disabilities.
