Measuring physiotherapists’ guideline adherence by means of clinical vignettes: a validation study

Vignettes are of acceptable validity, and are an inexpensive and manageable instrument to measure guideline adherence among large groups of physiotherapists. Further validation studies could benefit from the use of standardized patients as a gold standard, a more diverse case mix to better reflect real physiotherapy practice, and the inclusion of longitudinal vignettes that cover the patients' course of treatment.
