Reliability and internal consistency findings from the C-SEI.

Human patient simulation (HPS) is increasingly being used as both a teaching and an evaluation strategy in nursing education. To meaningfully evaluate student performance in HPS activities, nurse educators must be equipped with valid and reliable instruments for measuring student performance. This study used a novel method, including leveled, video-archived simulation scenarios, a virtual classroom, and webinar and e-mail communication, to assess the reliability and internal consistency of data produced using the Creighton Simulation Evaluation Instrument. The interrater reliability, calculated using intraclass correlation (2,1) and 95% confidence interval, was 0.952 (0.697, 0.993). The intrarater reliability, calculated using intraclass correlation (3,1) and 95% confidence interval, was 0.883 (-0.001, 0.992), and the internal consistency, calculated using Cronbach's alpha, was α = 0.979. This article includes a sample of the instrument and provides valuable resources and reliability data for nurse educators and researchers interested in measuring student performance in HPS activities.
