Given the need for a valid, reliable, and trustworthy instrument to evaluate nursing students&rsquo; perceptions and experiences of the OSCE, this study was conducted to develop and psychometrically evaluate the OSCE Perception Questionnaire (OSCEPQ).</span><br> <b><span style="color:black">Materials & Methods:</span></b><span style="color:black">&nbsp;A cross-sectional methodological study was conducted among eighth-semester nursing students from the School of Nursing at Alborz University of Medical Sciences, Iran. All eligible eighth-semester nursing students (n = 220) who undertook the OSCE during six consecutive academic semesters (July 2022&ndash;January 2025) were included in the study. Data were collected using the researcher-developed OSCEPQ and a demographic questionnaire. The sample was randomly split into two independent subsamples for Exploratory Factor Analysis (EFA; n = 120) and Confirmatory Factor Analysis (CFA; n = 100). Internal consistency was evaluated using Cronbach&rsquo;s alpha and McDonald&rsquo;s omega, and construct validity, including convergent and discriminant validity, was assessed.</span><br> <b><span style="color:black">Results:</span></b><span style="color:black">&nbsp;EFA extracted two factors comprising 19 items, accounting for 60.4% of the total variance. CFA showed an acceptable model fit (CFI = 0.99, RMSEA = 0.08). The scale showed strong internal consistency (> 0.90). Evidence also supported its convergent and discriminant validity.</span><br> <b><span style="color:black">Conclusion:</span></b><span style="color:black">&nbsp;The OSCEPQ showed satisfactory psychometric properties, including construct validity and reliability. It can be considered a valid and reliable instrument for assessing nursing students&rsquo; perceptions of the OSCE. Its application may support improvements in nursing education and evaluation practices.</span></span></span></span><br> &nbsp; students, nursing, psychometrics, reproducibility of results, educational measurement, health knowledge, attitudes, practice, clinical competence 0 0 http://edujournal.zums.ac.ir/browse.php?a_code=A-12-2275-3&slc_lang=en&sid=1 Maryam Aghabarary aghabararym@gmail.com 5300319475328460038735 5300319475328460038735 Yes Social Determinants of Health Research Center, Alborz University of Medical Sciences, Karaj, Iran Roohangiz Norouzinia norouzinia.r@gmail.com 5300319475328460038736 5300319475328460038736 No Social Determinants of Health Research Center, Alborz University of Medical Sciences, Karaj, Iran Mahsa Khedmatizare mahsa.khzare@gmail.com 5300319475328460038737 5300319475328460038737 No School of Nursing and Midwifery, Tehran University of Medical Sciences, Tehran, Iran.
