Development and psychometric testing of the narrative nursing teaching effectiveness scale: A methodological study

Background: Narrative teaching is widely used in nursing education. However, there is currently a lack of valid and reliable tool to assess the effectiveness of narrative nursing teaching from the perspective of nursing students. Objectives: This study developed a Narrative Nursing Teaching Effectiveness (NNTE) scale and evaluated its psychometric properties.Design: A methodological design was used to develop and validate the instrument.Settings: The study took place at a university in southern China. Participants: The study involved 283 nursing students enrolled at a medical university in Fujian Province, China.Methods: The researchers conducted literature reviews, held focus groups and individual interviews, and utilized the Delphi method to create a pool of indicators for a narrative nursing teaching evaluation system. A pretest was administered to 150 nursing students. Next, the primary study involved 283 nursing students, chosen through cluster sampling, completed a general information questionnaire along with the NNTE scale. Data analysis was performed using SPSS 26.0, Mplus 6.1, and STATA 16.0, and included general statistical analysis, critical test theory, and item response theory analyses.Results: The researchers created a 42-item scale with four subdomains, explaining 60.32 % of the total variance. Confirmatory factor analysis proved the four-factor model's validity. Cronbach's alpha values for the four sub scales ranged from 0.869 to 0.949. The average content validity index of the scale was 0.923 and the item content validity index ranged from 0.872 to 1. In addition, all item characteristic curves displayed desirable shapes, and the test information functions provided precise information.Conclusions: The NNTE scale exhibits good psychometric properties, providing a scientifically sound and effective instrument to evaluate the effectiveness of the narrative nursing teaching approach to nursing education.
