The aim of this study was to psychometrically evaluate the Clinical and Simulation General Self-Efficacy Scale (CSGSES) in a sample of 125 nursing students. The scale content validity index was .94. Exploratory factor analysis revealed a three-factor model with 16 items. Concurrent validity showed a positive association; Cronbach’s alpha was .875; test-retest reliability was significant. The revised CSGSES shows evidence of validity and reliability to measure nursing student self-efficacy concerning clinical and simulation. Copyright © 2022 National League for Nursing
