Parent Coaching Fidelity Trajectories of In-Person and Telehealth Sessions during the COVID-19 Pandemic.

The COVID-19 pandemic has posed significant challenges to delivery of preventive and mental health services, and providers have rapidly transitioned to telehealth service provision. Factors such as sudden isolation, financial strain, and physical and mental health stress presented unique challenges for providers and families and highlight the need for accessible and effective services. Thus, providers' fidelity of implementation during the pandemic is an important area for research. The current observational study compared providers' fidelity across in-person and telehealth-delivered sessions before and during the COVID-19 pandemic in Attachment and Biobehavioral Catch-up (ABC), a preventive parent coaching intervention for infants and toddlers. Participants included 24 providers (95% female, 42% White, age = 37) who participated in ABC training and consultation during the COVID-19 pandemic. Providers' fidelity data ( = 593 sessions) were modeled longitudinally using hierarchical linear modeling, and separate intercepts and slopes were estimated for in-person and telehealth-delivered sessions. When data were modeled across all available sessions, results indicated that providers demonstrated improving fidelity over the course of training. When in-person and telehealth-delivered sessions were compared, providers' fidelity in telehealth-delivered ABC sessions was not significantly different from their fidelity in in-person sessions. Providers demonstrated improving fidelity over time in telehealth-delivered sessions. Thus, providers were able to maintain and improve ABC fidelity during the COVID-19 pandemic when provided with implementation support. Rapid transition to telehealth delivery can be successful when ongoing support such as consultation is provided.
