What can early adulthood tell us about midlife identity?

Identity formation is a major developmental task in adolescence but continues throughout adulthood. Significant individual differences, however, emerge. The long-term role of personal styles for predicting identity stability and change during midlife at ages 36, 42 and 50 was assessed in a longitudinal study of Finnish women and men. Personality styles identified at age 27…
