Development and Validation of a Nursing Practice Self-Efficacy Scale in Welfare Facilities for Older Adults

Abstract

Objective: This study aimed to develop a Nursing Practice Self-Efficacy scale in welfare facilities for older adults and evaluate its reliability and validity.

Methods: Based on a literature review, a preliminary version of the Nursing Practice Self-Efficacy Scale for nurses in welfare facilities (23 items) was developed. A questionnaire survey was conducted, using a multistage sampling method, selecting 1,500 nurses from facilities nationwide to assess the scale’s validity and reliability.

Results: The analysis included 191 responses. Based on the results of exploratory and confirmatory factor analyses, a four-factor second-order factor model was established. The first-order factors were Medical Care, Maintaining a Stable Life, Interprofessional Collaboration, and Adaptation to Situational Changes, while the second-order factor was Nursing Practice Self-Efficacy. The model demonstrated a good fit to the data. Construct validity was confirmed through its association with general self-efficacy and by comparing two groups based on clinical ladder levels. Internal consistency, measured using McDonald’s ω coefficient, was .976.

Conclusions: The Nursing Practice Self-Efficacy Scale in welfare facilities for older adults, consisting of 4 factors and 23 items, demonstrated strong validity and reliability.
