RESUMO
In 2015, First 5 LA contracted with the RAND Corporation to perform an implementation and outcomes evaluation of its Welcome Baby universal home visitation program. RAND designed and executed a mixed-methods implementation and outcomes evaluation program that examined program fidelity across 12 sites in Los Angeles County, each site's community referral and resource process, staff and participant experiences with the program, factors that may influence program attrition, short-term outcomes, and the relationship between program fidelity and outcomes. Data from multiple sources were used, including interviews with staff and focus groups with participants, quantitative data from staff and participant surveys, data collected by staff and entered into an administrative database, and document review. There was significant variation across the sites in meeting fidelity thresholds. Staff qualifications and training, reflective supervision, enrolling clients in the maternity ward, and service dosage elements were most challenging. Sites performed well in participant perceptions of their home visitor, supervisory requirements, and home visit content. Considerable variation in sites' community referral and resource process was also found. Welcome Baby participants achieved better outcomes compared to local and national benchmarks in more than half of the areas measured, including more positive parenting practices, higher levels of any breastfeeding, and safer sleep environments. Few clear patterns were evident in terms of relationships between meeting fidelity thresholds and outcomes. It is important to note challenges in evaluation, such as the lack of data to assess some of the fidelity and outcome domains.
