The aim of this article is to evaluate the effectiveness of the implementation of a psycho-educational intervention programme. The objective of this programme was to achieve optimisation of self-concept and basic socio-emotional skills for comprehensive development in the adolescent stage. The sample consisted of 402 students from 19 groups from public secondary schools in the province of Badajoz. A quasi-experimental pretest-posttest design was applied with a control group using the Trait Meta-Mood Scale, Self-Concept Form 5, and the State-Trait Anxiety Inventory. The analysis showed that the programme was effective in the family and social dimensions of self-concept, while in the other dimensions, the changes were not statistically significant. The results for emotion perception, understanding and regulation show that there were no statistically significant differences in the experimental group, although there were significant differences in the control group.
