Abstract

Background: Self-care is a necessary measure against occupational injuries of nurses and improves nursing performance at the bedside. Nurses have different scales to measure self-care, and researchers are confused about choosing valid and reliable scales. This systematic review aimed to evaluate the measurement properties of self-care scales in nurses to identify the best available scales.

Methods: Four databases (PubMed, Web of Science, SCOPUS, and ProQuest) were systematically searched, with no date limiters, until 9 Jun 2023. A manual search was performed with Google Scholar and the reference list of articles to complete the search. Studies aiming to develop or determine the measurement properties of self-care in nurses were included. Based on Consensus-Based Standards for the Selection of Health Measurement Instruments, the methodological quality of the studies was determined, and the result of each study on a measurement property was rated (sufficient, insufficient, or indeterminate). The quality of the evidence was graded using a modified Grading of Recommendations Assessment, Development, and Evaluation approach (high, moderate, low, or very low). These processes were used to make recommendations and identify the best scale to assess self-care in nurses.

Results: Out of 8601 articles, six articles with five different scales were included. Only internal consistency was reported across all scales. Criterion validity, measurement error, responsiveness, feasibility, and interpretability, were not reported in any of them. Content validity was reported only in two studies with inconsistent results and low-quality evidence. None of the scales had methodological quality with a rating of very good and sufficient high-quality evidence for all measurement properties.

Conclusions: None of the scales is strongly recommended to measure self-care in nurses. Only the Professional self-care scale is temporarily recommended until their quality is assessed in future studies. Considering that the content of the examined scales does not meet all the professional self-care needs of nurses, designing a valid, reliable, and specialized scale for nurses is needed.
