Development and Validation of Narrative Competence Scale for Medical Students

Narrative competence in medicine enabled physicians to listen to patients' illness experiences, construct their narratives, and enhance reflective practice, empathy, humanistic literacy, and person-centered care. However, systematic research and clear definitions for measurable indicators of narrative competence assessment were lacking. This study aimed to develop and validate a narrative competence scale for medical students.

A 57-item draft scale was developed, and categorized into four dimensions and eleven sub-dimensions after interdisciplinary literature review. Three rounds of the Delphi method were conducted with eleven experts specializing in narrative medicine. Pilot testing involved 200 fifth- and sixth-year medical students in Taiwan (136 males, 64 females). Confirmatory factor analysis CFA) and Cronbach's α were used to evaluate the NCS-MS's reliability and validity.

The NCS-MS was refined through three rounds of the Delphi method, focusing on item revisions and sub-dimension definitions. The results of CFA indicated a good fit for the four-factor model (RMSEA = 0.055, SRMR = 0.045, GFI = 0.911, NFI = 0.926, IFI = 0.971, CFI = 0.970). The Cronbach's α coefficients for the four dimensions ranged from 0.797 to 0.942, with an overall α of 0.972, demonstrating excellent internal consistency reliability.

The NCS-MS effectively evaluated the narrative competence of medical students. From the perspective of narrative medicine, the NCS-MS served as a research or teaching assessment tool for assessing medical students' narrative competence in narrative medicine research, instructional design, and implementation.
