## Abstract

to validate the content of a guidance guide on self-care in the postoperative period of breast surgery for breast cancer.

a methodological study with content validity, carried out with 15 expert nurses and physiotherapists, between May and July 2022. Recruitment took place from the Lattes Platform, using snowball sampling. The level of relevance and representativeness for each item was verified using the Content Validity Index (CVI). It was considered valid when CVI was equal to or greater than 78% (0.78).

from the initial total of 37 items, two were excluded, as they had insufficient practical relevance and theoretical relevance, and another five items which, although presenting a CVI lower than the established cut-off, were suggested to be rewritten and grouped with other similar items.

thirty items were considered valid and demonstrated important and significant characteristics, constituting suitable material for application in clinical practice.

estudo metodológico com validação de conteúdo, realizado com 15 enfermeiros e fisioterapeutas especialistas, entre maio e julho de 2022. O recrutamento ocorreu a partir da Plataforma Lattes, por meio da técnica snowball. Verificou-se o nível de relevância e representatividade para cada item por meio do Índice de Validade de Conteúdo (IVC). Considerou-se válido quando o IVC foi igual ou superior a 78% (0,78).

do total inicial de 37 itens, foram excluídos dois, por apresentarem pertinência prática e relevância teórica insuficientes, e outros cinco itens que, embora apresentando IVC inferior ao corte estabelecido, seguiu-se a sugestão da reescrita e agrupamento a outros itens semelhantes.

trinta itens foram considerados válidos e demonstraram características importantes e significativas, configurando-se material adequado para aplicação na prática clínica.
