A study in contrasts: Supports and barriers to successful implementation of two evidence-based parenting interventions in child welfare.

Although evidence-based interventions (EBIs) are spreading to child welfare, research on real-world dynamics of implementation within this setting is scarce. Using a six-factor implementation framework to examine implementation of two evidence-based parenting interventions, we sought to build greater understanding of key facilitators and barriers by comparing successful versus failed EBI implementation in a child welfare setting. Semi-structured interviews were conducted with a purposive sample of 15 frontline practitioners and state-level managers. Interviews were transcribed verbatim and data analysis used a modified analytic approach. Our results showed the successful EBI was viewed more positively on all six factors; however, implementation was multidimensional, multilevel, and mixed with accomplishments and challenges. An accumulation of strengths across implementation factors proved beneficial. Implementation frameworks may be advantageous in organizing and explaining the numerous factors that may influence successful versus failed implementation. While encountering obstacles is largely inevitable, understanding which factors have shaped the success or failure of EBI implementations in child welfare settings may optimize future implementations in this context.
