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, 27-year-olds' different areas of life were under observation. The data were collected using a life situation questionnaire and a theme interview. In connection with the interview, the respondents completed two personality tests (Eysenck Personality Questionnaire (EPQ) and Sensation Seeking Scale (SSS)) included in this dataset. Both personality tests are standardised for Finnish people. The Eysenck Personality Questionnaire contains 101 yes/no questions, which explore for example the respondents' hobbies, anxiousness, and tendency to cheat in various games. The test is designed to reflect individual differences in such dimensions as extraversion, neuroticism, and psychoticism. In addition, there is a lie scale. The Sensation Seeking Scale consists of pairs of statements. The respondents were asked to select the alternative which better described their own preferences or feelings. For instance, the respondents chose between "I like wild and uninhibited parties" and "I prefer quiet parties with good conversation". The test is designed to measure the respondents' thrill and experience seeking and disinhibition. Background variable used: the respondent's gender.
