Work and Disability at the Age of 30 Years: A Sociomedical Study of a Birth-cohort from Bergen VI. Education,Intellectual Ability and Occupation

Abstract

The relationships between occupation, education and intellectual ability at 30 years of age are analysed with particular reference to type of school attended at the age of 14 years. Data utilized are derived from interviews, psychological tests, local files of various schools, and journals of the National Services for Mentally Retarded. The study comprises all live births in the year 1940 of mothers then residing in Bergen, a total of 1 570 persons. A sample was taken from this cohort after stratification according to type of school attended at age 14 years. The sample was supplemented with persons who had either attended Special Schools for the educable Mentally Retarded (EMR) or received care from the Services for the Mentally Retarded (SMR). The final sample consisted of 262 persons. A relationship was found for both sexes between type of school attended at the age of 14 years and level of general education at the age of 30. For men, both occupational training acquired and intellectual ability at 30 years were also clearly related to type of school attended at age 14 years. The test performance of the male group was superior to that of the female group. Differing careers in the two sexes may provide a clue as to the reason underlying this finding.
