Effects of Participating in Intergenerational Programs on the Development of High School Students’ Self-Efficacy

This study aimed to examine the effects of intergenerational programs on high school students’ development of self-efficacy. We used a quasi-experimental ex-post facto design with several follow-ups and conducted a questionnaire survey with 236 high school students. Results showed that the self-efficacy of students who experienced community activities increased over time after the intergenerational programs. Conversely, self-efficacy for students who had not participated in community activities did not change over the three years of the study. Findings indicate that participating in intergenerational programs promotes the development of adolescent self-efficacy through the experience of interaction with different generations in local activities.
