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, 14-year-olds' social behaviour and living circumstances were explored. The research stage also includes peer nominations and teacher ratings (FSD2073), and parent interviews (FSD2074). The interviews of the 14-year-olds included themes such as family, housing and living environment, school, self-image, use of alcohol and drugs, leisure, and hobbies. No predetermined response categories were used. The recorded interviews were classified only afterwards, when it was possible to observe the whole range of responses. First, the interviewees were asked about their living circumstances, household composition at the moment and in the past, how their day care was arranged in childhood, and whether there had been any maids or domestic workers in the family. The size of the apartment and opinions on the living environment were surveyed. In relation to school, the interviewees were asked how far from the school they lived, how they travelled to school, whether they usually liked school, and which subject they liked best. The interviewees told whether they had changed school, how they had felt about it, and whether any of their teachers had been close to them. They were also asked to evaluate their own school success and their parents' reactions to it. Some questions covered truancy. Opinions on the parents' attitudes to studying were probed as well. The interviewees were asked whether they usually tell their parents about their school day at home. The 14-year-olds' views on friends, violence, and plans after elementary school were queried, as well as their parents' attitudes to selecting friends, dating, and violence. The interviewees were asked to describe their mother and father, to tell about their work and health, and to determine how often they discussed various issues. The...
