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 30 years. At this research stage, data were collected using a life situation questionnaire, an interview, personality tests, self-rating questionnaires, and a medical examination. This dataset contains the medical examinations of 42-year-olds. The medical examinations consisted of separate sections conducted by a nurse and a physician.

The respondents' physical and psychological symptoms during the past six months were also surveyed, as well as their mental wellbeing and the health of their children, parents, and siblings. The medical examinations were conducted by a specially trained nurse and a general practice specialist, with the exception of the examinations conducted elsewhere than in Kyllö Health Centre in Jyväskylä. In these examinations, a nurse was not available because of the room arrangement. A nurse was present in 150 medical examinations. In the clinical examinations, the illness and disability diagnoses were recorded, as well as the year and certainty of the diagnoses. Various activity-limiting symptoms and aberrations were also charted, as well as the need for further treatment. The laboratory tests yielded information about, for example, complete blood count, lipids, blood sugar, plasma levels of total glycosylated...
