NAVARRETE FLORIANO, Gloria et al. Validation of the Shared Decision Making Questionnaire - physician version (SDM-Q-Doc) in Spanish. Rev Clin Med Fam [online]. 2020, vol.13, n.3, pp.190-197.  Epub Nov 23, 2020. ISSN 2386-8201.


To validate the Shared Decision Making Questionnaire - physician version (SDM-Q- Doc) in Spanish.


Cross-sectional, multicenter, clinimetric validation study.


Primary Care Units.


In the cross-cultural adaptation phase there were 31 family doctors, and in the validation phase there were 219, all active medical professionals at the institutional and / or private level

Main measures:

Cross-cultural adaptation (direct translation, synthesis and reconciliation of the version by an expert committee, reverse translation, reconciliation of the reverse translation with authors of the original questionnaire, comprehension analysis in a sample of patients) and psychometric aspects (reliability and validity).


Cross-cultural adaptation was performed, guide question 2 was homologated to SDM-Q-9. No negative values were observed in the corrected item-total correlation- with the total correlation; all are higher than 0.80. Cronbach's Alpha was 0.963. Item 1 explained a variance of 77.2%. The Kaiser-Meyer-Olkin (KMO) test was 0.924 with a statistically significant Barlett Sphericity. Pearson's correlation matrix shows a positive correlation; in general the inter-item relationship is greater than 0.606.


A useful, short and accessible questionnaire to be applied in Primary Care has been validated to measure shared decision-making from the physician's perspective.
