New Release: GUI Infant Cohort (5 Years) Wave 3 (Convention A questionnaire-based naming convention)

15 October 2015

Wave 3 of the Infant Cohort (5 Years ) is now available through ISSDA.

N.B. The version available uses the Convention A (questionnaire-based naming convention).

Data from the two waves of the Child Cohort are available using two different naming conventions. Two datafiles are provided for each wave. The two files for each wave contain the same cases and the same information, the only difference between them is the variable naming convention used. 

Convention A is a questionnaire-based naming convention, with the variable names relating to the question numbers on the questionnaires.

Convention B is essentially a longitudinal naming convention with topic-based names harmonised across both waves.

We expect Convention B (longitudinal naming convention) of wave 3 of the infant cohort later in the year.
