Operational and conceptual definitions of the antecedents and consequences of the nursing diagnosis “Excessive Caregiving Burden (00366)” in informal caregivers of people with heart failure

This dataset contains the conceptual and operational definitions of the components of the nursing diagnosis “Excessive Caregiving Burden (00366),” with a focus on informal caregivers of people with heart failure. The data are derived from a methodological study of content validity, conducted with 29 experts with clinical, academic, and/or scientific experience in the field. The material includes the diagnostic definition, defining characteristics, related factors, antecedents, and consequences identified through an integrative review and concept analysis, subsequently evaluated for relevance using a Likert-type scale. For each component, validation parameters are presented, including weighted median, Content Validity Index (CVI), and results of the Wilcoxon test. The criteria adopted for validation were weighted median ≥ 0.80, CVI ≥ 0.80, and p > 0.05. The data supported the refinement of the diagnostic structure, including reformulation of the definition and the proposal of new diagnostic elements. This dataset aims to promote methodological transparency, scientific reproducibility, and support for future research on the validation of nursing diagnoses, especially in the context of heart failure and informal care.

本数据集包含护理诊断‘照护负担过重（Excessive Caregiving Burden，00366）’各组成部分的概念性与操作性定义，研究聚焦于心力衰竭患者的非正式照护者。本数据集源自一项内容效度方法学研究，该研究共纳入29名具备该领域临床、学术及/或科研经验的专家。本数据集涵盖通过整合性回顾与概念分析确定的该诊断定义、定义特征、相关因素、前因与后果，以及采用李克特（Likert）量表对上述内容进行相关性评估的相关结果；针对每一组成部分，数据集均提供了其效度验证参数，包括加权中位数、内容效度指数（Content Validity Index, CVI）以及威尔科克森（Wilcoxon）检验结果。本次研究采用的效度验证标准为：加权中位数≥0.80、内容效度指数≥0.80，且p值＞0.05。本数据集的相关数据可为该诊断结构的优化提供支撑，包括对诊断定义的重新表述以及新增诊断元素的相关建议。本数据集旨在提升方法学透明度、保障科研可重复性，并为未来护理诊断效度验证相关研究提供支持，尤其是在心力衰竭与非正式照护领域。
