Abstract

Background: Strengthening the sense of meaning in life and psychological well-being brings benefits for mental health. The group particularly vulnerable to mental problems are young adults, therefore the aim of our research was to explore how a gratitude intervention will affect the sense of meaning in life, psychological well-being, general health and perceived stress among them. The research also took into account the issue of expressing gratitude.Method: The study involved 80 young adults who were randomly assigned to the experimental group that filled out the specially prepared diaries for a week or the control group. Participants completed the Meaning in Life Questionnaire, the General Health Questionnaire – 28, the Perceived Stress Scale, and the Ryff Scales of Psychological Well-Being twice.Results: In the experimental group significant increases were observed in three areas of psychological well-being: environmental mastery, relationships with others and purpose in life. The significant decrease was also noted in anxiety/insomnia and depression symptoms as well as in perceived stress. There were no differences in the level of meaning in life. There was a positive relationship between expressing gratitude and meaning in life and psychological well-being.Conclusion: Proposed gratitude intervention has the potential to enhance psychological well-being among young adults, however, it may not be effective in enhancing meaning in life.
