[Preventive parent training: results in the cognitive area]

In an intervention study, parents were offered courses on interpersonal interaction and child education. The evaluation procedures are briefly described and results concerning two types of course contents (knowledge of definition of a technical term; familiarity with an educational concept) are presented. It appears that after 45 months, knowledge transmitted in the course is still present, although with a loss of differentiation, depending on practical relevance of the course materials.
