Abstract
The psychological construct of ‘ikigai’ reflects the sense of having a ‘reason for living’ and has been associated with various positive health-related outcomes. This study presents an English translation of the Ikigai-9, empirically explores the manifestation of ikigai in the UK, and outlines its associations with facets of well-being. Three hundred forty-nine participants self-reported levels of ikigai as well as state measures of mental well-being, depression, anxiety and stress. Confirmatory factor analysis did not support the original three-factor model, favouring instead a single-factor solution. Results indicated that above sex and age, ikigai predicted greater scores of mental well-being and lower scores of depression. The Ikigai-9 has high internal reliability and presents a logistically convenient measure of ikigai for English-speaking populations. However, further validation (e.g. test-retest reliability) is required to develop a better understanding of the potential protective role of ikigai in mental health.
