Abstract

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.
