Through a cross-sectional design, this study examines whether practices of active participation (AP; that is, opportunities for decision making and leadership) and quality of relationships (QR) established between members of youth organizations (i.e., affective and instrumental support) relate to dimensions of youth`s identity (i.e., personal purpose, personal meaning) and sense of sociopolitical control (i.e., leadership, political efficacy). Participants (n = 347; 17-26 years) were drawn from 38 youth organizations in two regions of Chile. Results from multiple regression models controlling for demographics, length of involvement, and aim of the organization yielded significant interactions between QR and practices of AP on both indicators of identity and political efficacy. Only length of involvement in the organization was related to leadership outcomes. Findings highlight the powerful effects of the quality of the relational context of youth programs and organizations to actualize the benefits of AP.
