Child-to-parent violence and abuse is a form of family violence that is still very much hidden and a taboo subject in Belgium. The problem was recently brought to public attention once again, but research, policy and targeted assistance remain limited. This doctoral research aims to learn more about how parents, children, and siblings who are confronted with CPVA conceptualize and deal with this phenomenon Although the voices of these family members are mainly unheard in Belgium, we also see little attention to the perspectives of siblings themselves in international research. However, studies indicate that CPVA can also have detrimental effects on siblings. This can be both directly, when they experience violence and abuse themselves (sibling violence), or indirectly by witnessing abuse. In this contribution, we therefore zoom in on siblings' experiences of child-to-parent violence and abuse in Belgium, based on first insights from an online survey and semi-structured interviews.
