Transcultural Adaptation and Psychometric Properties of the Persian Version of the Clinical Learning Environment, Supervision, and Nurse Teacher Scale Among Undergraduate Nursing Students

<b>Objectives:</b> Clinical learning is the core of nursing education. The clinical learning environment, supervision, and nurse teacher (CLES + T) play a significant role in the formation of optimal clinical learning. So, this study aimed to investigate the psychometric properties of the Persian version of the CLES + T scale among undergraduate nursing students. <b>Methods:</b> In this cross-sectional study, 400 nursing students participated from March to December 2023 via a convenience sampling method. The exploratory (<i>n</i> = 200), confirmatory factor analysis (<i>n</i> = 200), and reliability of the Persian version of CLES + T were assessed. The analyses were conducted using SPSS V.22, AMOS V.27, and JASP V. 18. <b>Results:</b> The exploratory factor analysis extracted 6 factors (28 items), and the scale's overall explained variance was 41.61%. The confirmatory factor analysis indices confirmed the model fit (CFI = 0.90, PNFI = 0.72, IFI = 0.90, TLI = 0.90, and RMSEA = 0.055). The scale had acceptable internal consistency (<i>α</i>: 0.64-0.83). <b>Conclusion:</b> The results of this study support the validity and reliability of the Persian version of the CLES + T with 34 items and 5 factors. The role of the nurse teacher and the supervisory relationship were highlighted as key factors in creating a positive clinical learning environment among Iranian nursing students.
