Evidence of effectiveness

Results from an unpublished randomized control trial conducted in 2018 supported the effectiveness of Kindness in the Classroom with elementary school students. The evaluation included 586 students who were in grades 4 and 5 (83% spoke English as their 1st language and the average SES of the neighborhood in which the school was located was $58,054 (CAD)). This evaluation found that elementary school students who participated in the program had higher teacher and peer ratings of prosocial behaviors (i.e., teacher ratings = perspective-taking, gratitude, perseverance, intrinsic prosocial motivation, altruism, empathy, peer acceptance, and closeness; peer ratings = takes views), and engaged in less antisocial behaviors compared to students in the control group (outcomes reported 16 weeks after baseline while controlling for pretest scores). Self reports of students also revealed significant improvement in SEL skills and attitudes (perspective-taking, gratitude, perseverance, intrinsic prosocial motivation, altruism) for the treatment group over the control group.
