Evaluating Modular Approach to Therapy for Children with Anxiety, Depression, Trauma and Conduct Problems (MATCH-ADCT) in Norwegian child and adolescent outpatient clinics: Study protocol for a randomized controlled trial.

Background: Norwegian health, care, and welfare services are experiencing increased demands to deliver services that are safe, effective, of high quality, and that ensure user involvement. Yet, evidence-based treatment for common disorders such as depression, anxiety, trauma, and behavioral problems in children are not regularly used in clinical practice in Norway. Possible explanations for this are that many standard, evidence-based treatments may have difficulty addressing the complexity and comorbidity of referred children and the fact that children's treatment needs often shift during treatment.
