Feasibility and Acceptability of a "Train the Leader" Model for Disseminating Tai Chi Prime with Fidelity in African...

Background: African American (AA)/Black and Latinx communities have limited access to evidence-based fall prevention programs such as Tai Chi Prime (TCP). Community-led interventions that incorporate peer support are cost-effective and sustainable. Using the Treatment Fidelity Framework (TFF) and a mixed-methods research approach, we evaluated the training and support given to trainees during the TCP leader training pathway process and their subsequent fidelity in delivering six culturally tailored community courses. Methods: Trainees completed feedback forms after each TCP leader training pathway course. Using a fidelity checklist, a TCP master trainer rated six community TCP classes led by race- and language-concordant leaders. Trainees were invited to participate in virtual one-on-one semi-structured interviews to share their perspectives on the appropriateness and relevance of the TCP leader training pathway and their experience leading community TCP classes. Quantitative data was analyzed using descriptive statistics on Microsoft Excel. Three study team members coded qualitative data using directed content analysis approach. Results: Twenty-five candidates enrolled in the TCP leader training. Forty-eight percent identified as AA/Black while 52% identified as Latinx. Eleven trainees (six AA/Black and five Latinx) completed the entire TCP leader training pathway to become certified TCP leaders. Trainees rated the training process as highly satisfactory and appropriate. Leaders from both communities received high fidelity scores for community course delivery. Conclusions: Findings contribute to the existing literature, particularly regarding how to effectively disseminate and evaluate a culturally tailored TCP leader training and certification process for culturally diverse communities while maintaining fidelity to the curriculum.
