Abstract OBJECTIVE Developing and validating a scale to assess perioperative thirst discomfort. METHOD A methodological research conducted in 2014 and 2015 at the surgical center of a public hospital in the north of Paraná, Brazil. The scale was developed after literature review, followed by face and content validation, and reliability assessment through its internal consistency and inter-observer equivalence. RESULTS Seven items make up the scale: dry mouth; dry lips; thick tongue; thick saliva; dry throat, bad taste and desire to drink water. The content validity index for attributes and items was 0.98, and the reliability index was 1 for the scale attributes and items. Internal consistency assessed by Cronbach's alpha was 0.91 and inter-rater equivalence was 1, as measured by weighted kappa coefficient. CONCLUSION ThePerioperative Thirst Discomfort Scaleshowed high content and reliability indexes.
