An experimental study of positive effects of "gratitude" on interpersonal relations from the viewpoint of the broaden-and-build theory

本研究验证了感恩对人际关系的积极影响。实验研究表明，感恩对学龄前儿童的积极影响并没有得到充分发挥，而对学龄儿童的积极影响则得到了发挥，其人际关系得到了改善。在一项针对大学生的实验研究中，在美国已经发现的积极效果并没有被发现。在监测研究中，结果表明，那些容易感激的人对他人的帮助评价更积极，他们感到强烈的感激。从上面我们可以得出以下结论：感恩对人际关系的积极作用是有限的。

This research verified the positive effects of gratitude on interpersonal relationships. Experimental studies suggested that the positive effects of gratitude were not fully exerted for preschool children even if trainers taught them gratitude skills, and that the positive effects were exerted for school children, whose interpersonal relationships turned into better situation. In an experimental study to college students, positive effects which had already found in the U.S. were not able to be found out. In surveillance studies, it turned out that those who are easy to appreciate evaluated assistance from others as more positive one and they felt strong gratitude. From the above, we can draw the following conculusion that the positive effects of gratitude on interpersonal relationships are limited.
