Obstetric cardiopulmonary arrest: construction and validation of an instrument to assess nursing knowledge

Abstract

ABSTRACT Objective To build and validate an instrument to assess nursing knowledge about obstetric cardiopulmonary arrest. Methods A methodological study consisting of the construction of the instrument, content validation by 23 experts and validation of internal consistency with 74 nursing professionals and 99 nursing students. Items with a minimum agreement of 90%, verified from the Content Validation Index, Content Validity Ratio and binomial test were considered valid. Cronbach’s alpha was used to verify internal consistencyand a value greater than 0.6 was classified as acceptable. Results The instrument consisted of 16 multiple-choice questions, from the 16 items evaluated, eight had 100% agreement by the experts and six had 95%. The lowest content validity ratio was 0.82 and Cronbach’s alpha was 0.694. Conclusions The instrument was constructed and validated, and its use is recommended to assess knowledge in obstetric cardiopulmonary arrest.
