Several studies have shown an association between religiousness and different aspects of physical or mental health, and this makes important the articles as the one published by Taunay et al., which aimed to study the psychometric properties of the Brazilian version of the Duke Religious Index (P-DUREL) in psychiatric and university student samples. The instrument showed adequate internal consistency and test-retest reliability in both samples. We wish to add that using data from a study conducted by our group (not yet published) about the associations between religiousness and attitudes towards blood donation among postgraduate students of courses in the health area, we found a Cronbach’s alpha of 0.88 for the P-DUREL and 0.89 for the intrinsic religiosity (IR) scale in a sample of 160 individuals. We found Spearman correlation coefficients between the domains of organizational (OR) and non-organizational (NOR) religiosity of 0.58, between the domains of IR and OR 0.58, and between NOR and IR of 0.62 (all p-values less than 0.01). These results are similar to those of Taunay et al., suggesting that the psychometric properties of P-DUREL are also satisfactory for this specific group.
