Serious Game-Based School Intervention to Enhance Socio-Emotional Competence and Well-Being in European Adolescents

SEL4@ll is a school-based digital intervention targeting students aged 10-16 (Primary and Secondary Education). It combines: (1) a serious game with five missions promoting SEL skills (1/week), playable online at home or school; (2) a digital teacher handbook with classroom activities used 1-2 times per week; and (3) online surveys to assess impact. The program lasts 8 weeks: 2 weeks for pre/post assessments and 6 weeks of gameplay and classroom sessions. Surveys are administered online (3 waves), and optional focus groups are conducted with a subsample of students. Teachers complete an online evaluation after implementation.
