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.

Abstract

The data are part of the Jyväskylä Longitudinal Study of Personality and Social Development (JYLS), in which the same individuals have been followed since 1968. At this research stage, conducted in 2009, data were collected using a Life Situation Questionnaire, an interview, a personality test, questionnaires, and a medical examination.

Those who suffered from a disease or disorder were further asked what the year of diagnosis had been, what medication they used and whether their condition was improving or declining.

The women were asked whether their menopause had begun, what symptoms they had, and what medication they were using, if any. Other topics included: injuries that the respondents had sustained after the year 2000, the...
