The role of motivation in shaping social inclusion of people with intellectual disabilities in physical‐sports activity contexts

Abstract

The present study aims to test a model in which basic psychological needs (BPN) satisfaction in physical‐sport activity contexts is associated with self‐determined motivation, which, in turn, would predict the social inclusion of people with intellectual disabilities. A total of 286 people with intellectual disabilities (53.5% men) who reported engaging in physical‐sport activities responded to a validated questionnaire about the satisfaction of their BPN, motivation (using the Self‐determination index [SDI]), and social inclusion. A Pearson's bivariate correlation and structural equation modeling were conducted. The resulting model was reanalyzed in a multigroup analysis to test its invariance across self and proxy reports. Positive associations were found between the satisfaction of the BPN and the SDI. However, the SDI and social inclusion were positively associated only in proxy reports (βself = 0.07 vs. βproxy = 0.30). The tested model established positive relationships between the BPN and SDI in autonomy (βself = 0.21 vs. βproxy = 0.18), competence (βself = 0.47 vs. βproxy = 0.53), and relatedness (βself = 0.21 vs. βproxy = 0.23). Further research is needed to understand the factors leading to discrepancies between participants and proxies when relating the SDI to social inclusion in the context of physical‐sport activity. However, the results obtained suggest that it would be optimal to develop contexts of practice for people with intellectual disabilities in which the satisfaction of their BPN is favored and that this has a positive impact on their motivation and social inclusion.
