Building evidence of effective practice in child welfare requires practitioners and researchers to know the extent to which programs are implemented in order to understand evaluation results. Fidelity monitoring is a critical strategy for ensuring that evidence-based and promising practices are implemented as intended and can be studied in real-world contexts. This paper addresses challenges to measuring fidelity in child welfare systems and presents an approach taken with one state to define fidelity criteria and measure fidelity to a child safety intervention.

This study examined the relations among community violence exposure, inter‐partner conflict and informal social support and the behaviour problems of pre‐schoolers, and explored how mothers' parenting skills and children's social skills may mediate the child outcomes associated with such exposure.
