As part of the 1970 British Cohort Study Age 34 Sweep, half of cohort members with children aged 16 and under were randomly chosen to take part in a special study. Parents selected were asked to complete an interview module and a questionnaire about each of their children. Children aged three and over were set a variety of cognitive tasks and children over the age of 10 also completed their own questionnaire. This parent/child focus largely replicated the ‘Mother and Child Survey’, which was carried out with a representative sample of participants in the National Child Development Study cohort in 1991 when they were age 33.
