Abstract
|
|
|
Many prior studies have argued that grateful disposition is an important factor affecting happiness, and activities such as gratitude diaries and thank-you notes reduce depression. Based on this, we reviewed whether the grateful disposition reduces insomnia and depression. And we looked at whether optimism is a carrier in this relationship.
To this end, 455 university students were surveyed to measure their gratitude, optimism, insomnia and depression.
We also performed frequency analysis, regression analysis, and sobel test. Analysis shows that the higher the level of grateful disposition, the less insomnia and depression. Optimism also had a significant effect on insomnia and depression. And optimism played a significant mediating role in the relationship between gratitude and insomnia and depression. Based on these findings, the implications of university students gratitude and optimism were discussed.
