Wright J, Leveille S, Chimowitz H, et al., Validation of a brief scale to assess ambulatory patients’ perceptions of reading visit notes: a scale development study, BMJ Open 2020;10:e034517. doi: 10.1136/bmjopen-2019-034517
Four studies were used to evaluate the construct validity of a benefits and risks scale. Study 1 refined the items; study 2 evaluated underlying factor structure and identified the items; study 3 evaluated study 2 results in a separate sample; and study 4 examined factorial invariance of the developed scale across educational subsamples.
The findings suggest that the four-item benefits scale has excellent construct validity and preliminary evidence of generalising across different patient populations. Further scale development is needed to understand perceived risks of reading open notes.
