The proposed project is a randomized control trial to assess a novel 6-session parenting and coparenting intervention for low-income parents of infants. Connect to Baby (CTB) will be implemented within one of the largest federally-funded early care and education programs, Early Head Start (EHS), in Washington, DC. To engage both fathers and mothers, CTB recruits parents at the time of birth, capitalizing on the "magic moment" of delivery, and uses father-inclusive digital media content to engage men. A key innovation lies in the introduction and rehearsal of four interaction skills -- Noticing, Following, Talking, and Encouraging (NiFTE, pronounced "Nifty") -- to foster serve-and-return interactions with infants as well as supportive, cooperative coparenting interactions between mothers and fathers. To maximize program uptake, CTB is situated within an early education program parents already trust and attend. Additionally, the study will test hybrid program delivery with both in-person and remote sessions using video-enabled tablets to reduce scheduling and logistical barriers and thereby enhance retention. The specific aims of the project are to assess efficacy of random assignment to Hybrid delivery of CTB relative to EHS as usual at enhancing parenting and coparenting quality and parent and child wellbeing. If demonstrated to be efficacious, this program will provide Early Head Start (and other family-serving agencies) a brief cost-effective, manualized preventive intervention that could be used alone or in conjunction with other services to improve parent functioning and co-parenting, further engage fathers in programming and caregiving, and, ultimately, enhance child development.
