The interest of personality and social psychology for the enduring disposition to act prosocially resulted in the development of instruments capable of measuring such "goodness". The aim of the present study was to translate into Portuguese, adapt and evaluate the psychometric properties of the Prosocial Personality Battery, an instrument developed to measure individual differences in the disposition to act prosocially. Two studies were conducted to test the theoretical structure of the instrument and produce evidence of validity. In Study 1, the original instrument was translated using the back-translation method. The original structure was replicated and the psychometric properties observed were similar to the originally obtained. In Study 2, the structure was replicated again and the confirmatory factor analysis showed that, even though future improvements can be made, it replicates the original structure an can be used in Brazil to study prosocial behavior.
