This qualitative pilot study examined first-generation Latina mothers' experiences of supplementing home-based Early Head Start (EHS) services with the evidence-based Attachment and Biobehavioral Catch-up (ABC; M. Dozier, O. Lindheim, & J. Ackerman, 2005) program. Ten low-income, first-generation Latina mothers with infants and toddlers enrolled in home-based EHS were provided 10 ABC home visits by a supplemental parent coach. Following delivery of ABC, mothers participated in in-depth, semistructured, qualitative interviews about their experiences. Interview themes included positive experiences of both EHS and the ABC, a high value placed on receiving both programs, and cultural relevance of the ABC program for Latino families. Participants offered several suggestions for improved program delivery. Study findings suggest that a model of EHS supplemented by ABC delivered to the Latino community is feasible, valuable to participants, and culturally relevant. Considerations for sustainability of this supplemental model are discussed. (author abstract)
