One's happiness is expected to be affected by the happiness of surrounding others. This socio-psychological nature of happiness, however, has not been fully examined in the literature of social psychology. The current study examined if this “psychological interconnection of happiness” occurs when (i) individuals have strong personal social capital and/or (ii) individuals belong to a community where other members have strong social capital. We analysed a large social survey dataset sampled from 408 communities in Japan (N = 7295). The psychological interconnection of happiness was measured by calculating the correlation between individual happiness and perceived community happiness. The multilevel analyses revealed that the psychological interconnection of happiness was moderated by community-level social capital above and beyond individual-level social capital, while individual-level social capital did not have a significant moderation effect.

当其他成员看起来很开心时，您会感到开心吗？社区层面社会资本对幸福互联的调节作用

一个人的幸福会受到周围他人幸福的影响。然而，幸福的这种社会心理性质尚未在社会心理学文献中得到充分研究。当前的研究检验了这种“幸福的心理联系”是否会在 (i) 个人拥有强大的个人社会资本和/或 (ii) 个人属于其他成员拥有强大社会资本的社区时发生。我们分析了从日本 408 个社区（N = 7295）。通过计算个体幸福感与感知社区幸福感之间的相关性来衡量幸福感的心理联系。多层次分析表明，幸福的心理关联受到高于个人社会资本的社区层次社会资本的调节，而个人层次社会资本没有显着的调节作用。
