The Sport Commitment model (SCM) is a well-known theoretical framework to illustrate how the psychological state of commitment to sport has been influenced and studied in able-bodied persons. Considering the characteristics and lived experiences of people with disabilities, additional antecedents of sport commitment were added in the structure of the SCM. In order to extend the application of this revised SCM to persons with disabilities, the concept of three levels (personal, social, and environmental) of Bronfenbrenner’s ecological model was employed to differentiate the impacts of nine antecedents to sport commitment. The primary purpose of this study was to examine the revised SCM in terms of the magnitude of contribution of nine antecedents (enjoyment, personal investment, involvement opportunities, social constraints, involvement alternatives, self-efficacy, negative consequence of sport participation, social support, and accessibility of sport facilities and settings) on sport commitment to athletes with disabilities. The second purpose of this study was to investigate the superiority between original and alternative sport commitment models (mediation and direct/indirect model). A total of 157 adult athletes (Mean age= 34.87, SD = 11.78) with physical disabilities from team and individual sports across the United States, Europe, and Asia completed an online survey of 60 items across the nine antecedents hypothesized to influence sport commitment in athlete with disabilities. Results indicated involvement opportunities, followed by personal investment, were the strongest predictors of sport commitment (R2 = 65). In contrast, enjoyment, social constraints, involvement alternatives, self-efficacy, negative consequence of sport participation, social support, and accessibility of sport facilities and settings had no significant prediction on sport commitment. Chi-square difference test showed the direct/indirect model (χ2 (211) = 318.41; RMSEA = .05; CFI = .97; SRMR = .06) had better goodness-of-fit indices than the mediation model (χ2 (215) = 390.55; RMSEA = .06; CFI = .95; SRMR = .11). Based on the principle of parsimony, the original model (χ2 (215) = 384.95; RMSEA = .07; CFI = .95; SRMR = .06) was deemed a better model to understand the mechanism of sport commitment than the direct/indirect model. The SCM was an effective theoretical framework for adult athletes with disabilities. However, it still requires more studies to understand its effectiveness to other developmental ages and stages of athletes with disabilities.
