So far, there is no consensus in psychology research with regard to the relationship between religiosity and prosocial behaviour. However, this relationship is quite important for understanding the dynamics underlying prosociality in adolescence. In the present study, 1,170 Turkish adolescents (aged 12–17) from both religious and general schools were compared in terms of their prosociality (empathy, altruism and kindness), values and religiosity. The results indicated a positive relationship between religiosity and prosociality; however, there was no significant difference between the types of schools in terms of prosocial characteristics. Additionally, as hypothesised, intrinsic religiosity was positively correlated with self-transcendence and conservatism and negatively correlated with self-enhancement and openness to change. These findings suggest that religious schooling does not lead to greater prosocial behaviour, although religiosity was associated with prosociality in adolescence.
