Integrated behavioral health (IBH) in pediatric primary care settings can improve access to needed care and outcomes. Behavioral Health Workforce Education and Training (BHWET) programs can better prepare the workforce and support improved care access. This case study identified factors that impede and facilitate the implementation of practice-based training in a BHWET program using the Exploration, Preparation, Implementation, Sustainment (EPIS) framework. Surveys were administered to BHWET trainees and primary care partners to assess stakeholder perspectives on field-based training processes. Qualitative data were extracted from surveys and trainee clinical logs. Providers reported high levels of satisfaction with IBH care training experiences. Data analysis identified several implementation facilitators and barriers. Implementation facilitators were associated with two EPIS outer context factors (leadership and collaboration) and one inner context factor (partner staffing). Identified barriers were associated with two inner context factors (organizational characteristics and data collection). Although the facilitators and barriers identified in this study were program specific, they have relevance for similar programs. Barriers identified at the organizational level reflect those identified in the research literature and provide insights for university programs regarding factors that must be considered when integrating IBH training components in primary care settings.
