Perceived discrimination is a mental health stressor that involves individuals ability toperceive interactions and discriminatory experiences in their daily lives. The aim of this dissertation was to explore the associations between Perceived Discrimination and Psychopathological Symptoms. For this purpose, a three-part study was designed. It includeda literature review, a narrative review on perceived discrimination and disorders, symptoms, and other signs of psychological morbidity, and finally, an assessment of the psychometric properties of the Everyday Discrimination Scale along with an empirical study that evaluatedthe presence of psychopathological symptoms online and tested associations with perceived discrimination. A cross-sectional research design with quantitative analysis was employed, considering responses from 547 native Brazilian adults aged 18 to 72 years old. Participants completed four self-administered questionnaires: sociodemographic, Everyday Discrimination Scale, Psychological Distress Scale, and the Level 1 Cross-Cutting Symptom Scale from the Fifth Edition of the Diagnostic and Statistical Manual of Mental Disorders. Regarding the results, validity based on internal structure was conducted using Exploratory Factor Analysis,which found that all items functioned appropriately. The scale demonstrated unidimensionalityby assessing a single construct and showed convergent validity with external measures throughthe K10 Scale, designed to assess recent psychological distress reports. The hypothesis that stigma and discrimination might impact seeking psychological help was confirmed by this study. Our research supports that the Everyday Discrimination Scale possesses reliable properties for online use, enhancing the feasibility of studies in this area. Thus, we observed apositive association between the Everyday Discrimination Scale and psychopathologicalsymptoms as well as recent psychological distress.
