Development of a Workplace-based Assessment Scale for Student Anesthetist Nurses

Objective: To develop and validate a skills assessment tool for evaluating the workplace performance of student anesthetist nurses through a psychometric analysis of its reliability and validity. Materials and Methods: The study was conducted in three sequential phases: Scale Development: A comprehensive literature review and expert consultations were undertaken to construct the initial assessment items. Content Validation: Three expert anesthetists reviewed the draft scale for content validity. Psychometric Testing: The final scale was evaluated using data from 40 student anesthetist nurse assessments in 2023-2024. Recruitment was conducted in the gynecology surgery rooms. Results: The finalized workplace-based assessment scale consisted of 24 items spanning three key domains: patient and equipment preparation, technical skills, and non-technical skills. The psychometric analysis demonstrated stronginternal consistency (Cronbach’s α = 0.93), high inter-rater reliability (The Intraclass Correlation Coefficient (ICC) = 0.87), and moderate concurrent validity, as evidenced by Pearson’s correlation analysis (r=.511, p<.05, N=40). Conclusion: The newly developed workplace-based assessment scale exhibits strong psychometric properties, providing a reliable and comprehensive tool for evaluating the clinical competencies of student anesthetist nurses in practice settings.
