Caregiver coaching is an evidence-based practice for autistic children that is poorly implemented in community-based early intervention. Previous studies have identified factors that influence implementation of caregiver coaching in early intervention; however, multi-informant (e.g., caregiver, provider, leadership) qualitative research is lacking. As such, the purpose of this study was to simultaneously examine the perspectives of caregivers and early intervention providers and agency leaders for triangulation of perceived barriers and facilitators to caregiver coaching in community-based early intervention. Interviews with 36 providers, 6 agency leaders, and 20 caregivers of autistic children were conducted. We used qualitative thematic analysis to identify barriers and facilitators, which we then mapped onto the Consolidated Framework for Implementation Research post hoc. Several themes emerged, including at the outer setting level (i.e., COVID-19 pandemic), inner setting level (i.e., caregiver views toward telehealth), individual characteristic level (i.e., caregiver attitudes toward coaching, caregivers concerns preventing progress, caregiver expectations regarding services, caregiver stress), and implementation process level (i.e., caregiver and provider collaboration, caregiver and provider relationship, caregivers coordinating services, caregiver involvement, provider flexibility). We offer suggestions for implementation strategies that will increase adoption of caregiver coaching in early intervention for autistic children and their families.
