ABSTRACT

Background:

There has been a rapid expansion of digital healthcare services, making the need for measuring and improving digital health readiness a priority. In response, our study team developed the Mobile-Centered Digital Health Readiness Scale: Health Literacy and Equity Scale (mDiHERS), to measure digital health readiness.

Objective:

To develop and validate a scale that assesses digital health readiness, encompassing literacy and equity, and to ensure the effective use of mobile-centered digital health services.

Methods:

This study was conducted from October 2021 to October 2022 to develop and validate the mDiHERS. Participants included patients with inflammatory bowel disease (IBD) which is a chronic condition requiring continuous management, and experts in medical and nursing informatics. The scale development involved a literature review, focus group interviews (FGIs), and content validity evaluations. A total of 440 IBD patients were recruited for the validation phase, with 403 completing the survey. The scale's validity and reliability were assessed through exploratory factor analysis and Cronbach's alpha. The scale was translated into English by translators and bilingual and native researchers, ensuring its applicability in diverse settings.

Results:

The mDiHERS consists of 36 items across six domains, with a 5-point Likert scale for responses. The validation process confirmed the scale's construct validity, with four factors explaining 65.05% of the total variance. The scale's reliability was established with Cronbach's alpha values ranging from .84 to .91. The scale's development considered the technical proficiency necessary for engaging with health mobile applications and devices, reflecting the importance of subjective confidence and objective skills in digital health literacy.

Conclusions:

mDiHERS is a validated tool for measuring patients' readiness and ability to use digital health services. mDiHERS assesses user characteristics, digital accessibility, literacy, and equity to contribute to the effective use of digital health services and improve accessibility. The development and validation of mDiHERS emphasize the importance of confidence and competence in managing health digitally. Continuous improvements are necessary to ensure that all patients can benefit from digital healthcare.
