Prosocial behaviour in primary and secondary school students. Effects of the CYBUPRE intervention.

Prosocial behaviour is regarded as a critical factor in reducing aggressive behaviours among peers, both in physical settings and virtual spaces. This variable facilitates the enhancement of social relationships, promoting empathy, deep listening, physical and verbal service, and even solidarity, among other benefits. The objective of this research is to evaluate the efficacy of the CYBUPRE intervention in fostering prosocial behaviour, analysing the results on a general basis, and dividing them by educational stage to ascertain whether any differences were found depending on grade level. The study was conducted in the context of Physical Education, with a sample of 695 students of Primary Education (402 students) and Secondary Education (293). The age ranged from 10 to 15 years (M = 11.85, SD = 1.19), with the majority (90%) residing in rural areas. The study had a one-group quasi-experimental design, with pre-test and post-test measures. Significant differences were found in all the dimensions, with medium effect sizes observed in Empathy and Verbal Comfort, as well as Solidarity, and small effect sizes observed in Deep Listening, Physical and Verbal Service, and Physical Help. Furthermore, taking into consideration an analysis distinguishing between Primary and Secondary Education, the results revealed significant differences in all dimensions, with the exception of Physical and Verbal Service, and underscoring the Physical Help dimension which had a higher effect size at Primary level. Finally, due to the classification of the intervention as a short-term implementation, it can be adapted to the curriculum and needs of educational centres, allowing for the fulfilment of the competencies and objectives established in the educational programmes.
