Validation of the Simulation Effectiveness Tool in Nursing Education.

BACKGROUND: The Simulation Effectiveness Tool (SET) frequently is used to assess perceived learning and confidence in simulation. However, few studies have reported the validity of the tool. This study assessed the reliability and validity of the SET. METHOD: This retrospective analysis evaluated the tool using 568 cases conducted at three nursing schools. RESULTS: A two-factor model showed reasonable fit indices. The fit statistics for the two-factor structure were: chi(2), 152.98 (df = 53, p < .001); comparative fit index, 0.94; root mean square error of approximation, 0.05 (range, 0.04 to 0.06); and standardized root mean square residual, 0.04. In addition, weak convergence was identified between the confidence in the SET and responding in the Lasater rubric. CONCLUSION: The psychometric properties of the study indicate the SET has demonstrated acceptable evidence of validity and reliability to measure simulation effectiveness in Korean nursing students. The use of this instrument for brief simulation education is recommended. [J Nurs Educ. 2020;59(4):186-193.].
