积极心理学提出三件好事(three good things,TGT)练习可有效减轻抑郁症状,提升幸福感和心理健康。为检验基于微信社交平台的三件好事练习(TGT-SN)能否提升幸福感,本研究招募北京某高校研究生232名,自愿加入三个被试组(TGT-SN组133人,TGT组53人,对照组46人),体验、评估40天TGT前后及干预后一个月幸福感、抑郁水平、人际关系以及干预效果。研究发现抑郁得分持续改善,其他问卷得分无显著差异,但被试自评干预效果评估确认练习有积极作用。TGT练习效果有限,涉及方法有效性、样本量、参与者动机以及外部影响因素等,未来可基于优秀传统文化开展进一步研究以提高被试依从性及主动健康行为。

Abstract Background: TGT (three good things) exercise is one of the positive psychological interventions. Previous studies found that recording three happy things with their reasons every day could effectively reduce the symptoms of depression, improve the level of well-being and mental health. It has been found that college students (especially postgraduate students) have a high level of anxiety and depression. In addition, the intervention method of combining TGT practice with social network (QQ group) helps to improve the mental health of HIV-infected patients.

Objective: In order to examine the intervention effect of TGT exercise on postgraduate students, and to test whether the "three good things" exercise based on Wechat social platform can improve postgraduate students'well-being. The study explored the effect of TGT from quantitative and qualitative aspects

Methods: In this study, three groups of designs were adopted: the TGT group, the TGT-SN group (social network three good things, TGTSN; Complete the three good things exercise through the WeChat platform) and the control group (no practice, the WeChat administrator posted the psychology related materials). 232 postgraduate students were recruited from a university in Beijing. Participants voluntarily chose to join three groups (133 in TGT-SN group, 53 in TGT group, and 46 in control group). The TGT intervention lasted forty days, and participants' well-being, depression, interpersonal relationship, and intervention quality were evaluated before intervention, after intervention immediately, and one month after the intervention.

Results: The 40-day intervention was completed by only 150 participants (TGT-SN group 77, TGT group 40, control group 33). The loss of subjects was large and the compliance rate was low. Even if the participants knew that TGT exercise was beneficial to the body and mind and voluntarily participated in TGT exercise, they were still lack of motivation and difficult to adhere to it. The results showed that there was only a continuous improvement in depression scores (F (2, 125)=3.20, p=.01, partial n2'=.05), but no positive effects were found in well-being, life satisfaction, positive emotion, and interpersonal relationship scores. Combined with the quality evaluation of the intervention effect, the subjects reported that the TGT exercise was effective, and that Wechat was suitable as a mental health intervention platform. They also prefered to choose TGT intervention exercise based on Wechat social platform, which could increase the motivation of practice. The reason w场the effect of TGT exercise was not significant might be due to the multiple effects of research design, external emotional events, cultural differences and so on, and frequent daily practice would only increase the burden and reduce the exercise execution, and exercise three times a week would be more beneficial to the practice effect.

Conclusion: People can benefit from readily available, simple, well-being-enhancing interventions, so that future research needs to improve the TGT practice procedure to overcome the problem of people's own executive ability (knowing good but not doing)
