Midlife Development Lab
Keski-iän kehityksen tutkimusyksikkö
Department of Psychology, University of Jyväskylä, Finland
Lab Leader: Katja Kokko, Ph.D., Academy Research Fellow
Goals: Our research focuses on midlife development in the areas of personality, well-being, work, family, health and health behavior, and leisure activities. The interfaces between these areas are investigated as well. Our studies apply a lifespan perspective to midlife development. We examine questions such as
- Does midlife personality have roots in child temperament?
- How does well-being form and show continuity in mid-adulthood?
- How does identity develop from young to mid-adulthood?
- What is adaptive psychological functioning in midlife?
- Does one’s attitudes and practices during working career affect retirement, and how?
- Why do some individuals succeed at combining work and family responsibilities across time in adulthood while others fail?
- Does personality contribute to midlife health?
- Alcohol drinking in a lifespan perspective?
- Are there links between leisure activities, health behavior, and health in mid-adulthood?
- What are the associations between childhood background, the timing of adult life transitions, and mid-adult psychological functioning?
- Are there family structure and personality links to social relations in young and mid-adulthood?
Why are these questions and other such questions important? First, midlife development is generally less well understood than earlier and later developmental phases. Second, positive development in midlife, in particular, and its early roots need further understanding. Third, the interface between the various areas (i.e., psychological, social, and physical) of midlife remains significantly uncharted. Finally, understanding better the protective and risk factors in midlife allows improved understanding of successful aging.
Our analyses are based on the ongoing Jyväskylä Longitudinal Study of Personality and Social Development (JYLS), where the same participants have been followed from age 8 to their current age of 50. This longitudinal study was begun in 1968 by Professor Lea Pulkkinen. She remains the principal investigator of the JYLS until the end of the current funding period from the Academy of Finland (2012). Cross-cultural comparisons of the JYLS findings are being conducted with the Center of Analysis of Pathways from Childhood to Adulthood (CAPCA).
Current funding: Academy of Finland (grant numbers 127125, 118316, and 135347) and the Central Finland Regional Fund of the Finnish Cultural Foundation
