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.
