Cognitive measures in the Avon Longitudinal Study of Parents and Children

The cognitive measures included in ALSPAC between the ages of 4 months and 5 years were carried out as part of “Children in Focus” clinic visits. These clinics were attended by a sub-sample of 10% of the original ALSPAC cohort, who were picked at random from the last 6 months of ALSPAC births. Later cognitive assessments were carried out in the “Focus at …” clinics which were open to all of the ALSPAC cohort.

Additionally, the mothers of the original ALSPAC cohort children were invited to clinics (“Focus on Mothers”) where cognitive assessments took place.
