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 a life situation questionnaire, an interview, self-ratings based on various tests and methods, and two personality tests. This dataset contains the personality tests which were given to the participants in connection with the interview to be completed at home. The first personality test, the Karolinska Scales of Personality (KSP), contains 135 questions, and measures impulsiveness, anxiety, aggressiveness and social adaptation. The respondents' habits, opinions and feelings connected to different situations are tested. The second test is based on the results received from 27-year-olds and designed for the 1995 data collection wave. The test contains descriptions of various lifestyles, which the respondents evaluated in terms of suitability. The test includes separate questions for male and female participants. The male questions describe contradictory, passive, pleasure-seeking, extrovert, and undercontrolling lifestyles, whereas the female questions illustrate feminine, social, passive, and self-sufficient lifestyles. Background variable used: the respondent's gender.
