Researchers must have valid and reliable instruments to measure a concept of interest. Knowing that there was not a research instrument to measure depressive cognitions in the Portuguese language, this methodological research was designed to translate, back-translate, and analyze the psychometric properties of the Depressive Cognition Scale (DCS) in preparation for further research in measuring depressive cognitions in Brazilian adults with diabetes. This scale was chosen because it is a valid and reliable research instrument that have been used in various populations, including samples of adults with diabetes, in the United States. A sample of 40 bilingual Brazilian adults from the southern region of Brazil participated in this study. The findings suggested that the Portuguese version of the DCS had adequate semantic equivalency, validity, and reliability to examine depressive cognitions in Brazilian adults. This scale can now be tested in Brazilian individuals with diabetes.
