Main outcome measures Child behaviour checklist scores at each follow up interval for each of the following components (internalising scale: scoring on feelings of anxiety/depression, withdrawal, somatic complaints; externalising scale: scoring on aggressive behaviour, delinquent behaviour; and scales scoring on attention problems, thought problems and social problems). Individual scores were added to obtain a total problems score. Trajectories were analysed by gender and age.
