A Meta-Analysis on the Effectiveness of Gratitude Promotion Programs for South Korean College Students

This study delves into the importance and consequences of gratitude promotion programs for South Korean college students. It uses meta-analyses to evaluate the effects of such programs on this demographic, shedding light on their significance and implications. To that end, we selected 11 papers in which 683 persons participated as study subjects, analyzing them using the PRISMA methodology. We observed an overall effect size of 0.6671, categorized as above medium. The effect sizes of the sub-areas were cognitive (d = 1.37), emotional (d = 0.60), and behavioral (d = 0.77), with the cognitive area exhibiting the largest effect size. When categorized by program type, the effect size (d = 0.85) for the program involving gratitude practice and gratitude recording surpassed the effect size (d = 0.77) of the programs where participants solely engaged in gratitude recording. According to program execution durations, the largest effect size (d = 1.61) appeared in the group that executed the program for the longest period of at least 16 weeks. This study highlights the areas where gratitude promotion programs for college students prove to be most effective. These findings offer valuable insights for tailoring and developing gratitude promotion programs in the future.
