NCT05332236

Brief Summary

A German version of the Parent-Adolescent Communication Scale (PACS, Barnes \& Olson, 1982) will be validated in a large sample of children (10-18 years) and their parents. As a secondary objective, the association of communication quality, children's somatic symptoms and mental health will be explored. After two years, participants from the community sample will be contacted again to see whether baseline communication quality predicts adolescent mental health two years later.
