A growing number of evidence-based systemic treatments for adolescents with disruptive behaviour problems exist. However, it is not clear to what extent these treatments have unique and common elements. Identification of common elements in the different treatments would be beneficial for the further understanding and development of family-based interventions, training of therapists, and research. Therefore, the aim of this Review was to identify common elements of evidence-based systemic treatments for adolescents with disruptive behaviour. Several common elements of systemic treatments were identified, showing a strong overlap between the interventions. Investigation of these common mechanisms and techniques could potentially build strong universal systemic treatment and training modules for a broad spectrum of adolescents with problem behaviours..
