Starting from the premise of the incomparable importance of the parent-child relationship for development, Class2000, a wide-reaching programme for the promotion of health and prevention of addiction in primary schools, focuses especially on the integration of parents. A questionnaire survey among 1430 parents in Hesse with children in the second primary class shows that the overriding majority of pupils (90 %) speak about Class2000 at home and initiate discussions with their parents on health-related topics. The various Class2000 information materials are acknowledged by up to 77 % of parents (comparatively more rarely in the case of the fathers) and are read, as a rule, with interest. Specific information on the contents of the programme is for the parents rather more important than general stimuli. Invitations to special informative events are accepted by well 80 % of the parents. Class2000 convinces more than 82 % of the participants. 71 % of the parents are prepared to contribute to the costs of Class2000. 12 % are undecided in this regard. Participation in parent evenings increases the readiness for financial involvement.
