Psychometric Testing of the Chinese Simple Version of the Simulation Learning Effectiveness Inventory: Classical Theory Test and Item Response Theory

Abstract

Background: High-fidelity simulation (HFS) has become a widely used and established pedagogy for teaching clinical nursing skills. Nevertheless, there are few evidence-based instruments that validate the effectiveness of simulation learning in mainland China. Methods:The Simulation Learning Effectiveness Inventory (SLEI) was adapted and validated for use in this study. Psychometric evaluation, incorporating classical test theory and item response theory (IRT) methods, was performed with 533 third-year undergraduate nursing students who were recruited from Results: The findings of exploratory and confirmatory factor analyses revealed that the simplified Chinese version of the SLEI (SLEI-SC) was composed of six factors, namely, course arrangement, equipment resource, debriefing, clinical ability, problem solving, and confidence, which explained 60.84% of the total variance. The Cronbach's α, MIIC, marginal reliability, and test-retest reliability values obtained for the total scale were 0.88, 0.38, 0.96, and 0.88, respectively. Furthermore, the difference between the total scores for learning effectiveness pre-and post-course was statistically significant (t = 2.59, p < 0.05, Cohen's d = 0.60). IRT analysis showed that the SLEI-SC discriminates well between students with high and low levels of learning effectiveness and offers information about a broad range of learning effectiveness measures. The relationship between final course grade and total score on the SLEI-SC was statistically significant (r = 0.63, p < 0.05). Conclusion:We demonstrated initial psychometric evidence and support for the 31item SLEI-SC as a developmentally appropriate instrument for assessing the learning effectiveness of all phases of HFS use with nursing students.

Gender-Based Differential Item Function for the Positive and Negative Semantic Dimensions of the Relationship Satisfaction Scale with Item Response Theory

“…The difficulty (threshold) values, which reflect the probability that a person will score above or below a given threshold, were computed using the following equation: a parameter * difficulty (threshold) values = intercept. The criterion (a parameter > 1.00) was used [50,51], a practice widely adopted in recent IRT analyses [52][53][54]. Values > 1.70 are considered very high [55].…”

Nursing students' experience during their practicum in an intensive care unit: A qualitative meta-synthesis

“…The purpose of college theoretical education is to enable nursing students to obtain basic theoretical knowledge and clinical technology. Also, the ultimate purpose of clinical practicum education is to help integrate theoretical knowledge into clinical practice of nursing students and cultivate their clinical competencies ( 2 ).…”
