Objective <p>This study constructed a comprehensive competency evaluation Index system for clinical nursing instructors based on a Multifaceted Feedback Model, which can provide a scientific reference for the recruitment, appointment and competency assessment of clinical nursing teachers.</p> Methods <p>Based on the multifaceted feedback model, the initial draft of the evaluation index system was formulated through literature review, mixed-method research, and group discussions. The expert consultation method was then used to refine and finalize the evaluation system. The weight of each indicator was determined using the Analytic Hierarchy Process (AHP), and a consistency test was conducted to ensure reliability.</p> Results <p>Two rounds of expert consultations were conducted. The expert response rates were 100% and 93%, the authority coefficients were 0.922 and 0.929, and the Kendall's coefficients of concordance were 0.175 and 0.235, respectively. The final evaluation index system for the competencies of clinical nursing instructors consists of four first-level indicators, twelve second-level indicators, and fifty-six third-level indicators.</p> Conclusion <p>The comprehensive competency evaluation indicator system for clinical nursing instructors constructed in this study establishes a foundation for the recruitment, training, performance appraisal, competency evaluation and standardized management of clinical nursing teachers. Moreover, this system provides theoretical and practical references for cultivating high-quality nursing talents that meet the development requirements of new medical disciplines and the reform objectives of the medical and health system.</p>
