Jyväskylä Longitudinal Study of Personality and Social Development
The Jyväskylä Longitudinal Study of Personality and Social Development (JYLS) is one of the most long-term longitudinal studies of human development. The same participants (N = 369; born 1959) have been followed from age 8 to age 50. The main aim of the JYLS has been to examine continuity and interaction in different areas of life: (1) socioemotional behaviour and personality, (2) education and work career, (3) family of origin and one’s own family, (4) health behaviour and health, and (5) social adjustment and delinquency.
