This study examined self-determination skills among adolescents with intellectual disabilities (ID) in India and analyzed the relationship between self-determination and various socio-demographic factors. Employing a descriptive survey design, the research assessed 60 adolescents with mild to moderate ID using the adapted AIR Self-Determination Scale. Results indicated that most participants (53.3%) demonstrated moderate levels of self-determination, with 31.7% showing low levels and only 15% exhibiting high levels. Participants scored highest in "opportunity at home" and lowest in "capacity for self-determination." Significant differences in self-determination were found based on age, associated conditions, education level, vocational training, parental education, and father's occupation. Older adolescents, those without associated conditions, those receiving vocational training, and those with parents having higher education levels demonstrated significantly higher self-determination scores. No significant differences were found based on gender, type of schooling, family type, or mother's occupation. The findings highlight the importance of both individual capacities and environmental opportunities in fostering self-determination. Implications include the need for balanced interventions addressing capacity-building and opportunity provision, tailored approaches for different subgroups, and family-centered strategies to promote self-determination among adolescents with intellectual disabilities in India.
