Government of New Brunswick implemented One-at-a-Time (OAAT) therapy, a single-session approach to care, within Addiction and Mental Health (A&MH) services. We conducted interviews to understand determinants of implementation from program champions. Champions of the OAAT therapy implementation (N = 19; Child/Youth n = 8, Adult n = 11) working within A&MH services and school districts were recruited through the provincial implementation team. Transcripts were synthesized using thematic analysis. Determinants were organized as facilitators and barriers in accordance with the Consolidated Framework for Implementation Research (CFIR). Thematic analysis resulted in 18 themes and 5 recommendations. Facilitators within the inner setting included: (1) need for change and perceived benefits of OAAT therapy; (2) compatibility of OAAT therapy with previous practice and service processes; and (3) support received from champions and colleagues. Insufficient resources (e.g., staff and physical infrastructure), and a culture that favored long-term therapy were barriers. Navigating age of consent, and implementation around COVID-19 were barriers within the outer setting. Facilitators within the implementation process domain included: (1) interconnected teams across sites, regions and the province; (2) collaborative implementation planning; (3) flexibility to tailor implementation at sites; and (4) mentorship provided by champions. Insufficient standardization of the implementation and limited representation among affected parties (e.g., community partners) were barriers within the implementation process. This study elucidated determinants that influenced implementation of a new service delivery within an Eastern Canadian provincial health care system. Findings can serve as a heuristic for organizations looking to enact similar implementation initiatives.
