The TRAILS (Developmental Psychological Perspectives on Transitions at Age 60: Individuals Navigating Across the Lifespan) dataset is the latest follow-up of the Jyväskylä Longitudinal Study of Personality and Social Development (JYLS). The data was gathered in 2020-21, when the participants were about 61 years old. Previously, they have been studied at ages 8, 14, 20, 27, 36, 42 and 50. A total of 206 Finnish men (n=99) and women (n=107) participated in TRAILS. The data was gathered via life situation questionnaires, psychological interviews, self-report questionnaires, health examinations (inc. blood samples) and accelerometers. The topics covered in the dataset include e.g., personality, identity, mental well-being, life situation, work and retirement, future orientation, social relationships, leisure-time activities, use of modern technology, physical activity, health and health behavior, and physical and cognitive functioning. The former JYLS datasets (8- to 50-year-olds) are archived at the Finnish Social Science Data Archive (FSD): https://www.fsd.tuni.fi/en/data/misc/laku/. Detailed methodology descriptions can be accessed at the FSD data portal.
