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), 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
The mDiHERS is a validated tool that quantifies patients' readiness and influencing factors to engage with digital health services. It also considers the users' characteristics, capabilities, and perceptions that influence these areas. It emphasizes the importance of considering cultural and educational backgrounds in digital health readiness and advocates for comprehensive support to enhance accessibility and equity. The mDiHERS is meaningful because it is essential to use and widely adopt health mobile applications and devices.
