Testing the Effectiveness of Supportive Parents - Coping Kids

The aim of this clinical trial is to test the effectiveness of the parent training intervention Supportive Parents - Coping Kids (SPARCK) for prevention of childhood mental health problems. The main research questions are: • Is SPARCK effective in preventing and reducing negative outcomes and promoting positive outcomes for eligible children and parents compared with regular care practice? In addition, investigators will conduct an implementation study to examine relations between implementation determinants and implementation and clinical outcomes in the SPARCK intervention condition Participants in the effectiveness trial will be randomized to receive either the SPARCK intervention or active regular care practices provided by professionals in the Norwegian frontline services. Researchers will test the effectiveness of the SPARCK intervention at post treatment and six months follow-up.
