Development and validation of a rating scale for barriers to and facilitators of nurses’ participation intentions in “Internet + Nursing Service”

Abstract

Background

Given increases in China’s aging population, the growing demand for public health services and the shortage of human resources among nurses have become more prominent. Under such a background, “Internet + Nursing Services” have received more attention. Thus, exploring the barriers to and facilitators of nurses’ willingness to participate in “Internet + Nursing Services” and utilizing internet technology to increase the supply of nursing services has become a key issue.

Objective

This study aimed to develop a scale for assessing the barriers to and facilitators of nurses’ willingness to participate in “Internet + Nursing Services” and to test the validity and reliability of the scale.

Methods

A preliminary scale was developed based on a literature review, theoretical research, semistructured qualitative interviews, and two rounds of Delphi expert inquiry. A convenient sampling method was used for the questionnaire survey. A 5-point Likert scale was used to evaluate the importance of the items. The survey data of 659 clinical nurses obtained from February to March 2023 were used for item analysis, exploratory factor analysis (EFA), and reliability and validity tests of the scale. The survey data of 538 clinical nurses obtained in April 2023 were used for confirmatory factor analysis (CFA) of the final scale.

Results

The final scale consists of 25 items and 4 dimensions (performance expectations, perceived risk, need for professional knowledge training, and nonprofessional knowledge training). The scale showed good structural validity and content validity: the Cronbach’s α coefficient of the scale was 0.955, the split-half reliability was 0.778, the test-retest reliability was 0.944, the kaiser-meyer-olkin(KMO) value was 0.960, and the cumulative variance contribution rate of the 4 common factors was 83.147%. The scale content validity index(S-CVI) was 0.914. The confirmatory factor analysis model had favorable fit indices: χ²/df = 4.234, RMSEA = 0.078, NFI = 0.940, IFI = 0.953, TLI = 0.947, and CFI = 0.953.

Conclusion

The scale for assessing the barriers to and facilitators of nurses’ willingness to participate in “Internet + Nursing Services” has good reliability and validity, and provides a reference for evaluating nurses’ willingness to participate in “Internet + Nursing Services”.
