Purpose: The aim of this study is to design and validate the content of an instrument based on the Nursing Outcomes Classification (NOC) "Knowledge: disease process" and "Risk control: hypertension" to measure pregnant women's knowledge and self-care behaviors about hypertensive disorders.
Methods: The study was carried out in three phases: (a) content validity of the indicators, (b) construction, and (c) content validity of the instrument.
Findings: The instrument contains 72 items with an average content validity ratio and representativeness of 0.92. The items that did not reach the established values were eliminated or reformulated according to the observations made by the experts.
Conclusions: This study provides the first instrument for perinatal maternal care designed from the NOC that has demonstrated adequate content validity and representativeness of the NOCs on which it is based. The next phase in the development of the instrument is to test its validity and reliability.
Implications for nursing practice: CoNOCiTHE is a tool that can be useful in assessing pregnant women's knowledge and self-care behaviors about hypertensive disorders, contributing to the documentation and quality of maternal perinatal nursing care.
