Study on relationship between happiness level and communicational activities

在本研究中，我们在幸福感水平与社区活动的数量成正比的假设下进行了网络调查，并就幸福感水平、与家庭、工作场所、朋友等社区活动的总时间等问题进行了调查：约524名20至60岁的男女作为初步调查，约1075名20至60岁的男女作为主要调查。结果发现，幸福感水平与家庭活动总时间呈正相关关系，但其他活动与幸福感水平关系不强。然而，我们发现“你有某种奖励吗？”这个问题与幸福水平有很强的关系。

In this study, we conducted web research on the hypothesis that happiness level is proportional to the amount of community activities and questions regarding happiness level, total time of community activities with: family, workplace, friends, and so on: about 524 men and women from 20's to 60's as a preliminary survey, about 1,075 men and women from 20's to 60's as a main survey. As a result, we found relationship between happiness level and total time of activities with family, but other activities have not strong relationship with happiness level. However we found the question that “Do you have some kind of rewarding?" has strong relationship with happiness level.
