Association between religiousness and blood donation among Brazilian postgraduate students from health-related areas.

Objective: The aim of this study was to examine the association between religiousness and blood donation among postgraduate students.

Methods: The Portuguese-language version of the Duke University Religion Index was administered to a sample of 226 Brazilian students with ages ranging from 22 to 55 years. All study participants had completed undergraduate courses in health-related areas.

Translation into Portuguese and validation of the Blood Donation Reactions Inventory.

Background: the Blood Donation Reactions Inventory (BDRI) scale was proposed as part of a study about the predictors of psychological reactions in volunteer blood donors, as uncomfortable reactions are associated with a lower probability to return for further donations.

Objective: to translate the Inventory into Brazilian Portuguese and evaluate its psychometric properties (validity and reliability). The inventory has 11 items, but the literature suggests that shorter inventories, of four or six items, should be used.
