The aim of this chapter is to clarify how decision-making processes within the context of child welfare and child protection could be improved by decision-making theories (i.e., Decision-Making Ecology [DME] and decisional conflict model), with specific interest in methods intended to support practitioners based on these theories, in particular methods of structured decision-making and actuarial methods. Existing studies indicate that structured decision-making methods have a limited effect on the decision-making process, as well as on the reliability and validity of the judgments and choices made by professionals in cases of suspected child abuse and neglect. Actuarial methods may be more precise in making valid judgments but may ignore factors relevant to decisions concerning treatment and intervention. The DME framework reveals that other factors—in addition to rationally weighing information and arguing—influence the decision-making process and outcomes. Especially the influence of decision-maker factors seems to be ignored in structured decision-making methods. Although systematic methods and instruments do have some value, several additional options are available that take decision-maker factors more into account. This chapter discusses the potentials of critical thinking, team decision-making, systematic feedback, and shared decision-making.
