Psychometric evaluation of the Chinese version of the Snizek-revised Hall's Professionalism Inventory Scale

Objective This study was performed to assess the reliability and validity of the Chinese version of the Snizek-revised Hall's Professionalism Inventory Scale (C-SR-HPIS). Methods Exploratory factor analysis and confirmatory factor analysis were used to evaluate the construct validity of the C-SR-HPIS. The average variance extracted (AVE) and square root of the AVE were calculated and correlation analyses were performed to test the convergent validity and discriminant validity, respectively. Cronbach's alpha (alpha) coefficient was used to test the internal consistency reliability. Results Data for 355 clinical nurses in mainland China were collected. Five factors were extracted, accounting for 58.86% of the total explained variance, and 20 items were selected for the C-SR-HPIS. The confirmatory factor analysis suggested good fitness of the modified model. The AVE was acceptable for convergent validity. The square roots of the AVE of the five factors were larger than their correlation coefficients with other factors, showing suitable discriminant validity. Cronbach's alpha coefficient of internal consistency reliability of the overall scale was 0.76, indicating good reliability of the scale. Conclusions This study demonstrated good reliability and validity of the C-SR-HPIS and provides a quantitative tool for the assessment of nursing professionalism in China.
