BackgroundExposure to secondhand tobacco smoke (SHS) and child maltreatment are preventable threats to child health. Few evidence-based interventions target both SHS and child maltreatment risk. The purpose of this paper is to describe the systematic braiding process of two evidence-based programs to address child SHS in the home and maltreatment perpetration risk, and present results from the formative work and pilot study.MethodsThe first 4 steps of the systematic braiding process were completed, including the following: (1) the identification of core elements of both programs, (2) the development of an initial draft of the braided curriculum (Smoke-Free Home SafeCare — SFH-SC), (3) an acceptability and feasibility pilot of SFH-SC with caregivers of young children who reported a smoker living in the home (N= 8), and (4) feedback collection on the braided curriculum from SafeCare Providers (N= 9).ResultsExperts identified common pedagogical and theoretical underpinnings for the two programs and braidedSmoke-Free Homes: Some Things Are Better Outsideinto twoSafeCaremodules. Caregiver feedback from the pilot demonstrated that participants were engaged with SFH-SC and felt supported and comfortable discussing SHS intervention content with the SFH-SC Provider. Caregiver self-reports indicated a slight increase in smoke-free home rules from baseline to follow-up and a notable reduction in parent stress on the Parent Stress Index of 5.9 points (SD= 10.2). SafeCare Provider feedback following intensive review of the curriculum indicated high feasibility for SFH-SC delivery.ConclusionsParent and Provider findings suggest SFH-SC is a viable intervention that has potential to reduce the public health impact of SHS and child maltreatment for at-risk families.ProtocolThe protocol for the pilot is not published elsewhere; however, the full protocol for the hybrid trial can be found here:https://clinicaltrials.gov/ct2/show/NCT05000632.Trial registrationNCT, NCT05000632.
