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.

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, various aspects of the lives of 36-year-old participants were charted. This research stage includes an interview, a life situation questionnaire, two personality tests, and 20 self-rating questionnaires. This dataset contains the responses to the self-rating questionnaires, which were given to the participants during the interviews. The questionnaires are either original or modified versions of various tests and methods translated into Finnish. At the beginning of the interview, the respondents completed two questionnaires charting their emotions in terms of accepting, recognising and controlling them. Further questions covered transgressions, crimes, and moral conceptions. The respondents also estimated their self-esteem, mental and physical wellbeing, and alcohol use. One topic pertained to couple relationship. The respondents evaluated their attitudes towards the same and the opposite sex in terms of the four prototypical attachment styles (i.e. self-sufficient, secure, fearful, and clinging). Various ways of resolving disagreements were explored, as well as the respondents' aggressiveness, self-control, and ways of expressing emotions. Opinions were canvassed on the atmosphere of childhood home, raising children, and working hours. The respondents also described their own children in terms of obedience and concentration. Background variable used: the respondent's gender.
