The type of research was experimental with a quasi-experimental design. We worked with two groups: the G.E. and the control group (G.C.). The Pro-sociality Scale (Caprara, Steca, 2005) was used in its version translated into Spanish, in the pre-test and post-test phases in both groups. The results obtained in contrast between both groups indicate that the G.E. increased the pro-sociality with 36.77% being the significant difference between the G.C. of 30.2%.esSocialityHumanitiesPsychologyarticle
