From practice to evidence in child welfare: Model specification and fidelity measurement of Team Decisionmaking

Abstract

Fidelity measurement methods have traditionally been used to develop and evaluate the effects of psychosocial treatments and, more recently, their implementation in practice. The fidelity measurement process can also be used to operationally define and specify components of emerging but untested practices outside the realm of conventional treatment. Achieving optimal fidelity measurement effectiveness (scientific validity and reliability) and efficiency (feasibility and relevance in routine care contexts) is challenging. The purpose of this paper is to identify strategies to address these challenges in child welfare system practices. To illustrate the challenges, and operational steps to address them, we present a case example using the “Team Decisionmaking” (TDM; Annie E. Casey Foundation) intervention. This intervention has potential utility for decreasing initial entry into and time spent in foster care and increasing rates of reunification and relative care. While promising, the model requires rigorous research to refine knowledge regarding the relationship between intervention components and outcomes—research that requires fidelity measurement. The intent of this paper is to illustrate how potentially generalizable steps for developing effective and efficient fidelity measurement methods can be used to more clearly define and test the effects of child welfare system practices.
