Changing ourselves: how does personality change relate to well-being and authenticity?

Change in personality is viewed in two contrasting ways. Sometimes it is seen as an indicator of psychopathology or inauthenticity, associated with reduced well-being. Yet the ability to change oneself is also viewed as a sign of positive self-development, a process of becoming more authentic, and associated with increased well-being. This meta-analysis sought to compare these two perspectives and determine whether personality change can contribute to a good life. Sixteen independent samples (24,000 participants) were analysed to test the relationships between traits change and authenticity, traits change and well-being, and values change and well-being. Trait change was positively related to authenticity, while values change was associated with increased well-being. Moderator analysis indicated that type of change (over role or time) did not influence the relationship between trait change and authenticity, nor did length of time over which change took place influence the personality change and well-being relationship. Including traits and values allows a more holistic understanding of personality change and demonstrates that personality change is not damaging to living well, having instead a minimally positive association with well-being and authenticity.
