Adherence is one of the most studied variables about fidelity of implementation in school mental health field, but there are few studies that address it considering the strategic components of intervention. Objective. The aim was to investigate if patterns of adherence to strategic components influence the results of the Chilean Skills for Life program. Method. Data were collected from 110 communes in the country. The Quality Assessment Questionnaire for School Mental Health Programs was applied to coordinators of implementation teams and a communal index of socio-emotional improvement was created based on the responses of parents and teachers to the annual evaluation survey of the program. Results. We identified 19 components associated with strategies of intervention, design and evaluation, collaborative work and learning the Program model. With these components, we calculated latent class models and find two patterns of adherence. Finally, through ANOVA we evidenced that the teams that develop an adherent pattern obtain significantly higher results than those that develop a non-adherent pattern. Discussion. We concluded that the results of the program are better when the teams are adherent to some strategic components defined as essential. The practical implications of this finding are discussed.
