Background: Philosophy for children (P4C) was initially developed in the 1970s and served as an educational program to promote critical thinking, caring, creative reasoning and inquiry in the educational environment. Quasi-experimental research on P4C, a school-based approach that aims to develop children's capacity to think by and for themselves, has suggested it could be an interesting intervention to foster greater basic psychological need satisfaction in children in school settings.
Objective: The goal of the present study was to evaluate the impact of P4C on basic psychological need satisfaction and mental health in elementary school students.
Method: Students from grades one to three (N = 57) took part in this study and completed pre- and post-intervention questionnaires. A randomized cluster trial with a wait-list control group was implemented to compare the effects of P4C on students' mental health.
Results: Analyses of covariance (ANCOVAs) revealed a significant effect of group condition on levels of autonomy and anxiety, after controlling for baseline levels. Participants in the experimental group showed higher scores in autonomy, when compared to participants in the control group, and participants in the experimental group showed lower anxiety scores, when compared to participants in the control group.
Conclusion: Overall, results from this study show that P4C may be a promising intervention to foster greater autonomy in elementary school children, while also improving mental health.
