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 40 years. This research stage includes a Life Situation Questionnaire, interviews, personality tests, a life history calendar, a medical examination, laboratory tests and participant self-ratings. The lives of 50-year-olds were studied in terms of family, work, health, leisure and personality traits. This dataset contains the responses to self-rating questionnaires. The questionnaires were either original or modified versions of specific tests and measurements, translated into Finnish. The questionnaires filled in during the medical examination charted physical symptoms, self-control of emotions, interpersonal relations and traffic behaviour. The respondents were asked about physical symptoms experienced in the previous six months (e.g. headache, dizziness, low back pain). Control of emotions was charted with questions about experiencing, managing and showing them. A number of questions studied the respondent's relations to other people and social support available. Traffic behaviour was investigated by asking when the respondents had gotten their driver's license, how many road traffic accidents they had been involved in etc. The other questionnaires were filled in during the interview. Three questionnaires studied emotions in terms of accepting, recognising and controlling them. The first one investigated how the respondent was feeling at the moment of answering (e.g. disappointed, happy) and the second how the respondent felt in general (e.g. active, nervous). The next questionnaire covered aggression and the ways of controlling and showing it. The respondents' feelings of self-worth and self-appreciation were studied using the Rosenberg self-esteem scale. Psychological well-being was examined with 18 statements focusing on autonomy, personal growth, relations with others, purpose in life and self-acceptance....
