Psychometric properties of the persian version of the nursing clinical reasoning scale.

Abstract

The aim of this study was to translate the Nursing Clinical Reasoning Scale (NCRS) into Persian and evaluate its psychometric properties. This study was a methodological and cross-sectional study. This methodological study was conducted in 2020 in a teaching hospital. After obtaining necessary permission from its developers, NCRS was translated into Persian through the method proposed by the World Health Organization. Then, its face, content, and construct validity and reliability were assessed. For construct validity assessment through exploratory and confirmatory factor analyses, 300 nurses (two 150-nurse samples), who had randomly been selected, completed the instrument. Reliability also assessed through the internal consistency and the stability methods. Data were analysed using the SPSS (v. 20.0) and the AMOS (v. 5.0) software. The content validity indices of NCRS and its items were 0.97 and more than 0.79, respectively. Exploratory factor analysis revealed an assessment and confirmation factor and an implementation and reflection factor for the scale which together explained 57.30% of the total variance. Confirmatory factor analysis also confirmed this two-factor structure (χ2 /df = 2.11, NNFI = 0.952, RMSEA = 0.053, CFI = 0.91, GFI = 0.94, IFI = 0.95, and NFI = 0.96). The Cronbach's alpha and the intraclass correlation coefficient values of the scale were 0.96 and 0.94, respectively. The Persian NCRS can help nursing policy makers and mentors identify the need for developing nurses' and nursing students' CR skills and implement need-based educational courses to improve these skills. Moreover, it helps determine whether the educational programmes are effective in improving nurses' CR skills and clinical competence.
