Abstract
The present study evaluated the efficacy of an Italian school-based intervention programme adapted in three Colombian sites (Medellin, Manizales, and Santa Marta) in promoting prosocial behaviour among adolescents. Using a pre-test-post-test design with a multi-informant approach, the present study assessed 451 students (M-age = 12.77, SD = 1.06) of the intervention group and 428 students (M-age = 12.64, SD = 1.01) by using self-report and peer rating measures of prosocial behaviour. After establishing the measurement invariance across time and informants, a latent difference score model showed the positive effect of the intervention programme in improving prosocial behaviour evaluated by peers (Cohen's d = .379) among Colombian adolescents, across all three sites. Implications of the study will be discussed.
