摘要:This study examines the impact of the Building My Future program's implementation variables on attendance rate and on changes in personal, problem-solving, and community competencies. The program is run by local Social Services from Castile and Leon, Spain, and offers opportunities for adolescents to propose and carry out youth-led activities in their community. Data were accumulated from 356 participants, the majority experiencing negative psychosocial conditions, attending a total of 32 groups from 2013 to 2016. Using binary logistic regression and hierarchical linear regression analyses, results showed that having a facilitator with less professional experience, attending larger groups, having a high level of family involvement, and performing fewer modules and fewer extra activities predicted higher attendance rates and more positive task orientation, self-concept, social realization, and problem-solving competencies. Being younger, from an urban area, and having a facilitator with less professional experience predicted a higher score in community integration. These findings reveal that several program implementation components can contribute to the program's development and effectiveness and can also be considered across multiple programs in this field of practice.
