The PSQ-Brazil was applied to 137 diabetics from 31 to 89 years of age (60.6% women), clients of private pharmacies, mostly users of public health services (65.7%), with low education (67.9% elementary schooling or less), and who used an average of 4.3 medicines per person. Overall score in the sample was 3.6 (SD =1.1 [95%Cl3.4-3.8]). After factor analysis, "pleasant exposure" and "treatment management" included 8 and 12 items, respectively, and were significantly correlated with each other (r = 0.92, p < 0.001) and with the overall score. The instrument obtained a Cronbach's alpha of 0.98 for the overall score. The pleasant exposure and treatment management variables showed alphas of 0.94 and 0.98. PSQ- Brazil shows adequate reliability and validity for use in the country.
