This administrative case study describes a concurrent infusion of integrated behavioral health (IBH) practice into social work field and classroom instruction using the same manualized IBH treatment as the core treatment content. The infusion was applied to youth/young adult and older adult populations in field instruction and classroom instruction. Diffusion of innovation theory provided the framework for the infusion process and analysis. Quantitative data were extracted from Web-based learning platforms and administrative data sets and analyzed using descriptive and univariate statistical methods. Qualitative data were extracted from de-identified transcripts of student session segments and Web-based learning platforms and analyzed using phenomenological methods.
