摘　　要：Background:Today,mental illness is one of the most serious social issues in Japan.To proactively prevent psychological disorders and improve and maintain well-being,each individual must take action and engage in small yet significant daily activities for their well-being on a daily basis.The purpose of this study was to investigate if our daily engagement in oyatsu activities,sharing and giving snacks,can enhance hedonic and eudaimonic well-being.Methods:We conducted a randomized controlled,open-label,parallel-group comparative design trial.Participants were recruited from a community website run by a snack company in Japan.Participants who were 20 years old or older without currently experiencing physical or mental illnesses were included.The participants in the intervention group(n=152)were instructed to do oyatsu activities,defined as sharing or giving snacks to others,for one month intentionally,while the participants in the control group(n=154)were not given any instructions.Hedonic or subjective well-being(SWB)was measured using the Scale of Positive and Negative Experience(SPANE)and Satisfaction with Life Scale(SWLS),and eudaimonic well-being was measured by the Flourishing Scale(FS).A one-way independent t-test was conducted to determine statistically significant differences in the degree of improvement of the scores between the intervention and the control groups.Results:The primary outcome was the difference in change in FS scores from baseline to one-month follow-up between the groups,and the secondary outcome was the difference in change in SWLS and SPANE scores.We found a significant between-group difference in the improvement in FS score from baseline to one-month follow-up(t(280)=2.235,p=0.03),as well as SPANE-P(t(280)=3.514,p<0.001),SPANE-N(t(282)=−2.651,p=0.01)and SWLS(t(281)=2.842,p=0.01).Conclusions:Engaging in oyatsu activities might improve hedonic and eudaimonic well-being partly due to the prosocial nature of oyatsu activities.
