RESUMO
School Mental Health prevention approaches that use multi-tiered systems are advancing rapidly. However, there is a relative shortage of effective selective prevention programs feasible to implement within the school context. To optimize the effectiveness of selective prevention in this context, a Motivational Interviewing (MI)-based prevention program for an adolescent student population was developed and tested. Footprints utilizes MI to increase engagement in modular Cognitive-Behavioral Therapy and to promote academic protective factors. In this study, forty-three adolescents were randomly assigned to Footprints or a treatment-as-usual waitlist control. Participants in the experimental condition demonstrated significant increases in behavioral and emotional functioning, self-efficacy to regulate behaviors, positive expectations for success, academic motivation, and grades in mathematics. Simultaneously, Footprints received high ratings for feasibility and acceptability within a dynamic school context. This exploratory efficacy evaluation provides initial support for MI's potential to promote the effectiveness of school-based prevention programs and warrants further study.
