Developing and validating the Perioperative Thirst Discomfort Scale.

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.

OBJETIVO: Elaborar e validar uma escala para avaliação do desconforto da sede perioperatória.

MÉTODO: Pesquisa metodológica realizada em 2014 e 2015, no centro cirúrgico de um hospital público do norte do Paraná. A escala foi elaborada após revisão bibliográfica, seguida de validação aparente e de conteúdo e avaliação da fidedignidade através de sua consistência interna e da equivalência inter observadores.

RESULTADOS: Sete itens compuseram a escala: boca seca; lábios ressecados; língua grossa; saliva grossa; garganta seca; gosto ruim e vontade de beber água. O índice de validade de conteúdo para atributos e itens foi de 0,98, e o índice de fidedignidade foi de 1 para os atributos e itens da escala. A consistência interna avaliada pelo alfa de Cronbach foi de 0,91, e a equivalência interobservadores foi de 1, medida pelo coeficiente de kappa ponderado.

CONCLUSÃO: A escala de desconforto da sede perioperatóriademonstrou altos índices de validade de conteúdo e fidedignidade.
