Jyväskylä Longitudinal Study of Personality and Social Development (JYLS)

Jyväskylä Longitudinal Study of Personality and Social Development was initiated as Lea Pulkkinen's doctoral dissertation in 1968. Since then, the study has continued to follow the same individuals for over 40 years. When the project was launched, 369 eight-year-old children participated in the research. They were randomly selected among second-graders in primary school. After the first research, data have been collected when the respondents have been 14, 20, 27, 33, 36, 42, 50, and 60 years old. The latest data collection started in 2020. When the respondents were still in school, the...

Abstract

The data are part of the Jyväskylä Longitudinal Study of Personality and Social Development (JYLS), in which the same individuals have been followed over 30 years. At this research stage, data were collected through interviews probing 12 different themes. The recorded interviews were numerically classified according to the themes only afterwards, when it was possible to observe the whole range of responses. After that, each interviewer coded all the responses for one theme. The responses were then converted into variables describing the variation in the responses within each theme. The original open-ended answers are available in the dataset "FSD2200 Jyväskylä Longitudinal Study of Personality and Social Development (JYLS): Interviews of 27-Year-Olds 1986: Text Data". The research stage also included a life situation questionnaire and two personality tests. First, the respondents were asked questions about housing and mobility. Those who were married or cohabiting were asked about their spouse's age, where they had met, and how long their relationship had already lasted. They also indicated whether their parents accepted them as a couple. The couple's and spouse's hobbies were queried, as well as how well they knew each other's friends. They were asked to describe their relationship and to tell how well they thought it corresponded with their idea of a perfect marriage or relationship. Earlier marriages and relationships were also charted. The respondents were also asked about their children, child day care arrangements in their family, and their own childhood experiences on child day care. Views were probed on the essential things in organising children's lives, upbringing, and the respondents' usual activities with their children. Some questions probed corporal punishment. Further questions covered childhood memories and the respondents' parents. They were asked to describe their home and lives when they were 14 years old. Crimes committed by the respondents...
