This article is an investigation into the justice criterion for the items of the Positive Affect and Negative Affect Schedule (PANAS) considering contributions from the last decades on gender differences as to emotion and affect experience. For this purpose, the PANAS was administered to 354 participants of both genders. Data was evaluated under the paradigm of IRT, according to the model of polytomous responses suggested by Andrich (1988), and the criterion of justice in accordance with the Differential Item Functioning on the parameters suggested by Linacre (2011) comparing male and female samples. Evidence indicates differential item functioning for specific items, favoring groups according to their characteristics
