Results: The Portuguese short version of the Positive and Negative Affect Schedule has two distinct dimensions of positive and negative, reliable and stable, obtained by interview and questionnaire. Conclusions: The validity and reproducibility of the Portuguese short version of the Positive and Negative Affect Schedule in people with chronic kidney disease were consis-tent with the original version and the version of the Portuguese scale.
