Child-to-parent violence (CPV) is associated with youth substance problems; however, CPV which is substance-involved (SU-CPV) is specifically excluded from the consensus definition of CPV and few studies have explored the familial context surrounding SU-CPV. This study by Deakin University utilised the I3 model to explore associations between parental monitoring, parental intrusiveness, affective reactivity, concurrent reactive CPV and SU-CPV in an Australian community sample of caregivers.
