The Frustration Discomfort Scale (FDS) assesses beliefs about frustration intolerance. This study aimed at adapting this instrument to the Brazilian context, providing evidence for content validity of internal structure, and based on the relationship with external variables. In addition, we verified the relationship of the level of frustration intolerance with the gender and age of the participants. The sample consisted of 293 individuals, with an average age of 21.6 years(SD = 3.57). The FDS, the Patient Health Questionnaire-4 (PHQ-4), and a sociodemographic questionnaire were applied. The exploratory factor analysis results indicated the best solution to be a structure with two dimensions. Good indexes of internal confidence were found for both factors and the whole scale. A positive and statistically significant association was observed between the FDS and PHQ-4, which attests to the validity based on its relationship to external variables. No statistically significant differences of frustration tolerance were identified for gender or age. Based on these findings, we conclude that the adapted version of the FDS has satisfactory psychometric properties and is suitable for investigating intolerance to frustration, enabling researchers and professionals to investigate how this construct is manifested in the Brazilian population and how it relates to variables associated with mental health.
