Evaluation of a manual-based programme for the promotion of social and emotional skills in elementary school children: results from a 4-year study in Portugal

Abstract

The promotion of socio-emotional skills in educational contexts is highly beneficial to individuals' global adjustment and development. Evaluation research suggests that interventions for the promotion of socio-emotional skills are effective. However, most of this work has been carried out in the USA and there is now a pressing need to evaluate interventions at the cross-cultural level. This 4-year study evaluated the effectiveness of a teacher manual-based intervention for the promotion of social and emotional skills in Portuguese elementary school children. Using a quasi-experimental design, teachers taught manual-based strategies to children in the experimental group, focusing on specific social and emotional skills. These strategies were integrated as part of the curricular activities. Results showed statistically significant differences between the experimental group and the control group on the evaluated outcomes (self-control, emotional differentiation, emotional regulation, social skills, and self-esteem). For each of the dimensions studied, effect sizes were large (above 0.80). Findings are similar to those reported by international research evaluating the effectiveness of programmes for the promotion of social and emotional skills in school-age children. This study is an important contribution in the establishment of evidence-based socio-emotional skills programmes at the cross-cultural level.
