Reanalysis of "Timing Effects of Listing Gratitude Toward One’s Parent(s) on Subjective Well-Being Study"

The data of published paper (Kobayashi, 2017) that had been analyzed by multivariate analysis of variance was reanalyzed by multivariate analysis of covariance. The reanalysis could offer clearer results than the original analysis did. All the findings, including statistically nonsignificant findings, were reported for the sake of future meta-analysis.
