Validation of Nursing Outcomes Classification: Knowledge and Self-management for Cardiac Disease.

The Nursing Outcomes Classification provides two outcomes, Knowledge: Cardiac Disease and Self-management: Cardiac Disease, to assess knowledge and self-management behaviors of adults with cardiac disease. The purpose of this study was to validate the two nursing-sensitive outcomes to establish content validity. A methodological design was used using the Delphi technique. A total of 13 nurse experts in two domains participated in this study: five in standardized nursing terminologies and eight in self-management. Descriptive statistics and the Nurse-Patient Outcome Content Validity method were used to validate four aspects: definition adequacy of each outcome, clinical usefulness of measurement scales, importance of outcome indicators, and content similarity between the two outcomes. The definition adequacy, clinical usefulness, and content similarity of both outcomes were acceptable. A total of 81 indicators from the two outcomes were validated, and 60 were designated as critical. Nurses can evaluate cardiac patient outcomes effectively and accurately using these validated outcomes. The validated Nursing Outcomes Classification outcomes will also support the clinical decision-making of nursing students when they learn about patients with cardiac disease.
