 This study examined the concept of social participation from the perspectives of both experts and parents of youth aged between 10 and 17 years. It found that the subjective and objective components of social participation differed between these two groups. Experts focused primarily on the subjective aspect, while parents focused on the normative expectations for participation. Additionally, the study highlighted the importance of environmental factors in facilitating participation, such as accessibility and adaptability.
