Objective: To examine associations between temperament traits and early retirement intentions. Methods: In the Northern Finland Birth Cohort 1966, we analyzed early retirement intentions at the age 46 according to Cloninger temperament traits at the age 46 (n ¼ 4409) and at the age 31 (n ¼ 3226). Ordinal logistic regression analyses were used. Adjustments were made for marital status, education, work type, job satisfaction, perceived health, and mental health problems. Results: 11% of men and 9% of women had strong retirement intentions. Especially higher harm avoidance was associated with higher early retirement intentions in both sexes at the age of 46. A similar pattern of results, although with weaker associations, was found for temperament assessed at the age of 31. Conclusions: Temperament and especially harm avoidance is related to early retirement intentions.
