The aim of the research was to determine the influence of adapted sport on the identity formation of adolescents with a mobility impairment. An empirical investigation was carried out to investigate the relationship between certain variables, such as social relationships and affective constructs, and the identity formation of adolescents with a mobility impairment as information emerged from the literature study. A sample of 140 adolescents with a mobility impairment was drawn using purposive sampling. An instrument to measure the identity formation of adolescents with a mobility impairment was compiled. The data, which were obtained from the implementation of the instrument, were analysed using qualitative content analysis techniques. The major findings of the study revealed that there was no significant difference in the identity of adolescents with a mobility impairment who participated in sport, compared with the identity of adolescents with a mobility impairment who did not participate in sport. There was however, a significant positive correlation between social relationships with friends and parents, and the identity formation of adolescents with a mobility impairment. There was also a positive correlation between affective variables and the identity formation of adolescents with a mobility impairment. The two positive affective constructs with the highest correlation were trustfulness and gregariousness. The negative construct with the highest correlation was depression. Based on the findings, conclusions were drawn and recommendations were made. The relationship of adolescents with their friends and parents, together with the health of adolescents, explained the largest proportion of the variance in the identity formation of adolescents with a mobility impairment, namely 42%. The remaining 58% of the variance in the identity formation has not been significantly explained as yet. The implications for parents and educators are clearly explained. / Psychology of Education / D. Ed.
