Single-item indicators that ask respondents for their global rating of a specific concept are congruent with nursing's emphasis on wholism and individualism. They allow the subject to take personally salient features of the situation into account when providing a response. The psychometric performance of single-item indicators in published research and in a sample data set using measures of the mother's choice and satisfaction with her employment decision support the validity and reliability of the measures, suggesting that these indicators deserve more attention in nursing research. Recommendations for the use of single-item indicators are provided.
要求受访者对特定概念进行整体评价的单项指标,与护理对整体观和个人主义的强调相一致。它们使受试者在做出回应时能够考虑到该情况中对其个人而言显著的特征。已发表研究以及使用母亲对其就业决策的选择和满意度测量方法的样本数据集中,单项指标的心理测量性能支持了这些测量方法的有效性和可靠性,这表明这些指标在护理研究中值得更多关注。文中还提供了使用单项指标的建议。
