PROJECT SUMMARY/ABSTRACT This Diversity Supplement research supplements the larger i-STRONGER initiative, which investigates the effectiveness of a high-intensity rehabilitation intervention in Skilled Nursing Facilities (SNFs). Anticipating variable clinician implementation across multiple SNFs due to pilot results and the involvement of 120 clinicians, this supplementary project employs innovative quantitative methods to comprehensively evaluate both facility and clinician factors influencing i-STRONGER implementation. Aim 1 focuses on facility factors, utilizing multilevel linear regression to assess the impact of leadership strength, staffing ratios, and overall facility culture on clinician implementation. Aim 2 delves into clinician factors, employing multilevel linear regression to analyze demographics, clinical experience, leadership roles, self-efficacy, and perceived barriers. Innovatively departing from prior qualitative approaches, this project aligns factors with the Theoretical Domains Framework for translation of results into actionable behavior change techniques. Dr. Frannie Westlake will receive mentoring from Dr. Jennifer Stevens-Lapsley and Dr. Jeri Forster for rehabilitation research and biostatistics respectively. Dr. Westlake's career development plan aims to address research skill gaps through biostatistics training, clinical outcomes education, dissemination and implementation research, and overall professional development. This research project, with its comprehensive approach and innovative methods, is poised to significantly impact the understanding of clinician implementation factors, providing valuable insights for the optimization of future healthcare interventions in SNFs, while providing a rich training experience for Dr. Westlake. The comprehensive career development plan is strategically aligned with Dr. Westlake's overarching goal of contributing significantly to health-related research. The mentorship team will provide the necessary guidance and support to ensure Dr. Westlake's success as she advances in her journey towards becoming an independent investigator and influential figure in rehabilitation research.
