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

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. In this cross-sectional study, 400 nursing students participated from March to December 2023 via a convenience sampling method. The exploratory ( = 200), confirmatory factor analysis ( = 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. 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 (: 0.64-0.83). 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.
