Reliability and validity of the Chinese version of the Nurse Prescribing Self-Efficacy Scale.

Abstract

This study aimed to translate the Nurse Prescribing Self-Efficacy Scale (NP-SES) into Chinese and evaluate its reliability and validity. A systematic methodological framework was used. The study's setting was hospitals and nursing schools in Jiangsu province, China. A convenience sample of 309 practising nurses and nursing graduates was recruited. The reliability and validity of the scale were assessed. Item screening was based on critical ratio values and item-total correlation coefficients. Validity was evaluated through content validity, exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). Internal consistency was assessed using Cronbach's α coefficient and split-half reliability. EFA identified three common factors, accounting for 78.608% of the total variance. CFA indicated that model fit indices met acceptable thresholds, supporting the scale's structural validity. Cronbach's α and split-half reliability for subdimensions ranged from 0.907 to 0.957 and from 0.867 to 0.944, respectively. The Chinese version of the NP-SES demonstrates good reliability and validity and is suitable for assessing clinical nurses' self-efficacy in prescribing.
