Substance use has been associated with child-to-parent violence (CPV), yet little is known about the contributing factors. This study by Deakin University investigated the association between parental substance use and substance involved child to parent violence (SU-CPV; i.e., the young person is influenced by a substance), and whether this association was unique to SU-CPV compared to other co-occurring functions of CPV (proactive/instrumental, reactive/response to threat, affective/emotion-related).
