Psychosocial aspects of participation in youth disability sport were examined using social-cognitive theory and the sport commitment model. An international sample of athletes with disabilities (N = 112) reported high levels of sport commitment and sport enjoyment, perceived physical ability, and sport friendship quality. They perceived their parents to provide moderately strong levels of encouragement of their sport participation. Correlational analyses indicated moderate to strong relationships among sport commitment, sport enjoyment, and perceived physical ability. Sport commitment, parental encouragement, and sport friendship quality were only somewhat related. Regression analyses indicated that enjoyment was a significant predictor (i.e., 43% of the variance) of sport commitment. The sport experience was a positive one for these athletes and enjoyment is likely a critical motivational factor in promoting a continued desire to remain in sport.
