The Effect of Nostalgic Contents on Self-Esteem: The Mediating Role of Loneliness

Background: Research has demonstrated that nostalgia can improve self-esteem as a positive psychological resource in Western culture. Moreover, nostalgia is cross-culturally consistent. Therefore, nostalgia triggered by an event reflection task affects self-esteem in Eastern cultures. However, it is unknown whether the collective or personal content of nostalgia affects self-esteem and the role of loneliness in this process.Purpose: This study examined the cross-cultural consistency of nostalgia's impact on self-esteem, whether nostalgic content affects self-esteem levels, and what role loneliness plays in this process. Methods: We conducted two experiments in this study. Experiment 1 used an event reflection task with different instructions to prime the nostalgia and control groups. Participants were asked to complete the Positive and Negative Affect Scale and a revised positive version of the Rosenberg Self-Esteem Scale after priming. Experiment 2 used different instructions and pictures to prime the social and personal nostalgia groups. The PANAS, a revised positive version of the Rosenberg Self-Esteem Scale, and the Russell Loneliness Scale were then administered to the groups.Results: Experiment 1 showed that in the nostalgic condition, self-esteem was higher than in the control condition. In the nostalgia condition, participants felt more positive than in the control condition. Experiment 2 revealed that self-esteem was higher in the collective nostalgic context than in the personal nostalgic context. Regarding the positive effect, participants felt more positive in the collective nostalgic context than in the personal nostalgic context. Loneliness also had a mediating effect on this process.Conclusion: Results show that nostalgia affects self-esteem through cross-cultural consistency and social nostalgia can be a resource for positive mental health. Moreover, loneliness plays a significant role in mediating nostalgia's effect on self-esteem.
