UNLABELLED: AIN: This paper aims to describe the development of a tool, the Student Survey of Simulation Standards for Continuous Improvement (S4CI), to accurately measure student simulation experiences related to the 2021 International Nursing Association for Clinical and Simulation Learning (INACSL) Standards and the unique needs of University of Hawai'i (UH) Translational Health Science Simulation Center. BACKGROUND: In 2021 INACSL published their updated guidelines which should be integrated throughout the nursing curriculum and be measured to allow students to learn skills, develop clinical reasoning abilities and become competent in caring for patients/families in a safe environment. DESIGN: This study is designed as a cross-sectional survey study collecting data from nursing and Interprofessional Education students at the UH Mānoa. METHODS: The authors reviewed existing tools and adapted items as needed with the consultation of subject matter experts. They validated the tool by administering surveys to nursing and interprofessional students following simulation exercises. Confirmatory factor analysis to verify the factor structure and reliability tests were performed to assess the internal consistency of each item within a measure, respectively. RESULTS: Survey data from 1182 respondents showed reproducible factor results with strong correlation and reliability results showed high coefficient alpha values for all measures. CONCLUSIONS: The S4CI is a valid and standardized tool to provide faculty with valuable feedback to evaluate learning, optimize achievement and improve aspects of activities in nursing and interprofessional educational simulations. The study is, however, limited by sample size and generalizability, as it was conducted in a single center.
