Development and Testing of the Web-Based Learning Self-Efficacy Scale (WBLSES) for Older Adults

Abstract

Web-based health information is particularly important for the increasing number of older adult online users. One strategy to deliver synthesized, evidence-based health information to these individuals is through Web-based learning modules. There is, however, a lack of research in the area of using Web-based learning for older adults. To assess the effects of Web-based health learning modules, older adults’ ability to use the modules must be assessed. This article described the development and testing of the psychometric properties of the Web-Based Learning Self-Efficacy Scale (WBLSES). Initially, the eight-item WBLSES was developed based on an in-depth review of the literature, prior findings, and expert consultation. Preliminary psychometric testing was conducted using a single group descriptive study (N = 33) and the WBLSES was then retested among a larger sample of 221 older adults. The findings supported the reliability of the WBLSES as evidenced by appropriate internal constancy and stability, and the validity through hypothesis testing and Rasch analysis. Further studies are needed using other Web learning programs and more diverse samples.
