Assessing the effectiveness and the mechanisms of the Social-Emotional Prevention Program for Preschoolers: Findings from a universal school-based intervention.

The Social-Emotional Prevention Program (SEP) encompasses a multifaceted approach (classroom curriculum, with teacher and parent training) intended to increase preschool children's social adjustment, as well as to reduce risk of emotional and behavioral problems. The present study's focus was on implementing the technology-assisted SEP version and was aimed at (a) investigating the program's effectiveness on children's social-emotional competencies and parental practices, as well as (b) testing the program's conceptual framework, with an emphasis on children's emotion regulation (ER) skills and parental emotion socialization practices as explanatory intervention mechanisms. A randomized-controlled trial (RCT) was conducted with five schools assigned to either the intervention or to a comparison condition (wait-list control).
