There is significant evidence that emphasizes the importance of social and emotional learning in schools for students' positive development and adjustment. The main goal of the present study was to evaluate the effectiveness of a socioemotional skills promotion program, implemented with a group of socioculturally vulnerable young adolescents. Data were collected in the 2020-2021 school year from all students from 6th grade (n = 50, from four classes) in a high-risk school in Portugal (56% females). Two classes served as the comparison group. Participants responded to self-concept and emotional and behavioral problems measures at two moments (pre- and post-intervention). Results indicated a significant impact on self-concept, namely an increase in behavioral adjustment, happiness, and satisfaction and a decrease in anxiety in the intervention group compared with the comparison group. These findings support intervention efficacy. Educational implications are discussed.
