Content validation of the nursing outcome Knowledge Heart Failure Management: Brazilian nurses' opinions.

PURPOSE: To estimate the content validity of the outcome Knowledge: Heart Failure Management (1835) of the Nursing Outcomes Classification (NOC). METHODS: A methodological study conducted in Brazil with nurses with expertise in cardiovascular nursing and nursing process. The nurse experts evaluated the relevance of the indicators for the nursing outcome on a 5-point Likert scale. A total of 55 indicators were analyzed, including 50 NOC indicators, four indicators located from a scoping review, and one suggested by an expert during the content validation process. The relevance ratio supported the categorization of indicators as critical, supplemental, or unnecessary. Relevance ratios of critical and supplemental indicators were summed and divided by the total number of the indicators to calculate the outcome content validity (OCV) score of the nursing outcome. FINDINGS: Fifteen nurse experts, mostly females (n = 13) with a mean age of 36.0 ± 6.3 years, 13.9 ± 6.5 years of professional experience, and extensive use of the nursing process in their clinical practice (n = 10), teaching (n = 13), and research (n = 11), participated in this study. Regarding the content validation, 43 (78.2%) out of 55 indicators were categorized as critical (relevance ratio .80-.98), 11 (20%) as supplemental (relevance ratio .67-.79), and one indicator (1.8%) was categorized as unnecessary (relevance ratio .48). The OCV score of the nursing outcome was .87. CONCLUSION: The study provided evidence of content validity of 49 indicators of the NOC outcome, Knowledge: Heart Failure Management, and five new indicators identified through the validation process based on nurse experts' opinions. IMPLICATIONS FOR THE NURSING PRACTICE: These findings provide evidence-based indicators for the measurement of heart failure patients' knowledge about disease management. As a result, nurses can test the effectiveness of nursing interventions based on valid outcome indicators.

The Nurse-Patient Outcome Content Validation Method.

PURPOSE: To describe a new method of validating nursing outcomes and indicators that incorporates nurses' and patients' perspectives. METHODS: The Nurse-Patient Outcome Content Validation Method was developed in light of the experience of conducting the content validation of the nursing outcome Knowledge: Heart Failure Management (1835). It was developed based on Fehring's content validation model used for the validation of NANDA International nursing diagnoses. It expands the concept of who is an expert in the validation of nursing outcomes. FINDINGS: The Nurse-Patient Outcome Content Validation Method is a new method in which the concept of experts is expanded to gather patients' as well as healthcare professionals' perspectives on the importance of indicators to measure an outcome. Based on the importance ratios, the indicators are grouped into three categories: critical, supplemental, or unnecessary. To validate the outcome, importance ratios of critical and supplemental indicators are summed and divided by the total number of the indicators to calculate the outcome content validity (OCV) score of the nursing outcome. CONCLUSION: The Nurse-Patient Outcome Content Validation Method is a new method of content validation of nursing outcome and indicators that incorporates the patient perspective. IMPLICATIONS FOR NURSING PRACTICE: The Nurse-Patient Outcome Content Validation Method provides a mechanism to include nurses' and patients' perspectives to content validity research of nursing outcomes. It supports patient empowerment since the patient is viewed as an expert regarding the experience of living and managing his/her clinical condition.

Conceptual and operational definitions for the indicators of the nursing outcome classification: Symptom control in patients with heart failure in palliative care. / Definiciones conceptuales y operacionales de los indicadores del resultado Control de síntomas para pacientes con insuficiencia cardíaca en cuidados paliativos.

OBJECTIVE: To validate conceptual and operational definitions of Symptom control (1608) indicators for patients with cardiac diseases in palliative care. METHOD: Definitions were established through a literature review and were validated by consensus among expert nurses. Two rounds of the Delphi method and a meeting with experts were carried out in order to validate the definitions for the indicators and for the magnitude of response for each indicator. RESULTS: Conceptual and operational definitions for Symptom control (1608) indicators and for the magnitude of response for each indicator were validated. CONCLUSIONS: All conceptual and operational definitions of 11 indicators of the nursing outcome Symptom control (1608) were validated by experts. Content and clinical validation studies remain necessary to verify the capacity of the indicators to measure the effectiveness of nursing interventions in clinical practice and research.

Content validation study of nursing interventions intended to prevent cardiovascular events in diabetic patients.

AIMS AND OBJECTIVES: To validate nursing interventions from the Nursing Interventions Classification for preventing cardiovascular events in outpatients with diabetes. BACKGROUND: Cardiovascular disease is the main cause of death among diabetic patients. Although nurses play an important role in preventing cardiovascular events in this population, their specific contribution is difficult to measure. Documenting nursing interventions using a standardised nursing system may provide nursing visibility. However, there are no studies that analysed which nursing interventions would be the most relevant, based on expert opinion, aimed at preventing cardiovascular events in diabetic patients. DESIGN: This is a content validation study, which was designed as a descriptive one. METHODS: For this content validation study, we used the Fehring model. Nursing interventions were selected from the Nursing Intervention Classification. Experts were asked to analyse the degree of relevance of 225 nursing interventions regarding the prevention of cardiovascular events in diabetic patients, considering its title and definition. We considered nursing interventions which obtained weighted arithmetic averages >0·80 to be valid. RESULTS: Among 50 invited experts, 14 (71·4% female; 36·5 + 9·7 years) responded and agreed to participate in this study. They analysed 225 preselected nursing interventions, and validated 29. CONCLUSION: The validated nursing interventions included documentation as well as biological, social and spiritual issues. RELEVANCE TO CLINICAL PRACTICE: The validated nursing interventions encompass a wide range of nursing knowledge, and these results provide empirical evidence for further studies.
