The YNTR survey 9/10 targets the development of emotional and behavior problems, as assessed by the Child Behavior Checklist 6-18 (CBCL). From 2001 onwards, the Conners’ Parent Rating Scale — Revised (CPRS-R) was also included. In addition, these surveys included items on zygosity, medical conditions, vaccinations, tonsillectomy (from 2005), demographic characteristics, growth, sport and leisure activity of both children and parents, and additional items on well-being (from 2010).
