The families were identified as part of the risk group during their fourth-year visit to a child health clinic. The Finnish child health clinics provide regular check-ups that offer universal health care and are attended by 99.6% of the children. > During the study, the parents were offered research-based support for parenting by teaching daily parenting and problem solving skills. The training took place on the internet and by telephone.
