Berger LE, Jodl KM, Allen JP, McElhaney KB, Kuperminc GP (2005) When adolescents disagree with others about their symptomes: Differences in attachment organization as an explanation of discrepancies between adolescent, parent, and peer reports of behavior problems. Dev Psychopathol 17:509-528 CHC nurses have attached study information, consent, and three sentences of SDQ (one for each of the child`s legal guardians and the other for the teacher) to the invitation letter that parents routinely receive about three weeks before the routine examination of their 3- to 5-year-olds. Written information about the studies asked parents to give the questionnaire to the teachers of the child`s kindergarten and teachers were asked to complete the questionnaire and then return it in a prepaid envelope to the child`s CHC nurse. Parents were asked to complete their questionnaires and return them with their consent when participating in the child`s visit to the CHC. . . .
