“…The systemic practitioner requires a different type of knowledge based on the acknowledgement of child abuse as a real phenomenon, with real harmful effects, and with treatment methods aimed at the child, the abuser and the family. Such an approach is consistent with critical realism as a philosophy of science position, as it also includes the understanding that the social world is socially constructed (Bhaskar, 2010; Bhaskar & Danermark, 2006; Kjørstad & Solem, 2018; Sayer, 2011). Based on critical realism, systemic practitioners must therefore apply a dual perspective where, for example, diagnoses are regarded as social constructs while recognising that there are also children and adults with mental health problems.…”
