Objective: Using a theory of change framework, this study examines outcome measures of a home visitation program that provided services to first-born children and their parents living in southwestern New Mexico. Method: Home visitation workers conducted pretest and posttest assessments for prenatal and postpartum periods for 109 families receiving services in the First-Born Program. Families were assessed using the Revised North Carolina Family Assessment Scale. Paired sample t tests were used to assess effect. Results: Clients participating in the First-Born Program displayed significantly higher posttest scores on measures of family resiliency. Specifically, clients demonstrated improved scores in operationalized measures of resilience: social support, caregiver characteristics, family interaction measures, and a reduction in personal problems affecting parenting. Conclusion: The results are promising as participants were observed to make positive improvements in specific areas related to family resiliency. (Contains 7 tables and 1 figure.)
