To estimate the content validity of the outcome Knowledge: Heart Failure Management (1835) of the Nursing Outcomes Classification (NOC).
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.
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.
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.
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.
评估护理结局分类（NOC）中“知识：心力衰竭管理”（1835）这一结局的内容效度。
在巴西对心血管护理及护理程序方面的专家护士开展了一项方法学研究。护士专家采用5级李克特量表评估各项指标与护理结局的相关性。共分析了55项指标，包括50项NOC指标、通过范围综述确定的4项指标以及在内容效度验证过程中由一位专家提出的1项指标。相关性比率用于支持将指标分类为关键指标、补充指标或非必要指标。将关键指标和补充指标的相关性比率相加，再除以指标总数，以计算该护理结局的结局内容效度（OCV）得分。
15名护士专家参与了本研究，其中大多数为女性（n = 13），平均年龄36.0 ± 6.3岁，专业经验13.9 ± 6.5年，且在临床实践（n = 10）、教学（n = 13）和研究（n = 11）中广泛应用护理程序。关于内容效度验证方面，55项指标中有43项（78.2%）被归类为关键指标（相关性比率0.80 - 0.98），11项（20%）为补充指标（相关性比率0.67 - 0.79），1项指标（1.8%）被归类为非必要指标（相关性比率0.48）。该护理结局的OCV得分为0.87。
本研究为NOC结局“知识：心力衰竭管理”的49项指标及通过基于护士专家意见的验证过程确定的5项新指标提供了内容效度证据。
这些研究结果为衡量心力衰竭患者疾病管理知识提供了循证指标。因此，护士可基于有效的结局指标来检验护理干预措施的效果。
