ABSTRACT

Background:

The use of digital health technology (DHT) in diabetes self-care is increasing, making electronic health (eHealth) literacy an important factor to consider among people with type 1 diabetes. There are very few studies investigating eHealth literacy among adults with type 1 diabetes, highlighting the need to explore this area further.

Objective:

The aim of this study was to explore associations between eHealth literacy and demographic factors, disease-specific factors, and well-being among adults with type 1 diabetes.

Methods:

The study used data from a larger cross-sectional survey conducted among adults with type 1 diabetes in Sweden (n=301). Participants were recruited using convenience sampling method primarily through advertisements on social media. Data were collected between September and November 2022 primarily through a web-based survey although participants could opt to answer a paper-based survey. Screening questions in the beginning of the survey determined eligibility to participate. In this study, eHealth literacy was assessed using the Swedish version of the eHealth literacy scale, Sw-eHEALS. The predictor variables well-being was assessed using WHO (Five) Well-being Index and psychosocial self-efficacy using Swedish version of the Diabetes Empowerment Scale. The survey also included research group developed questions on demographic and disease-specific variables as well as DHT use. Data was analyzed using multiple linear regression presented as nested models. A sample size of 270 participants was required in order to detect an existing regression model based on an F test. The final sample size included in the nested regression model was n= 285.

Results:

The mean Sw-eHEALS score was 33.42 (SD 5.32; range 8-40). The model involving both demographic and disease-specific variables, explained 31.5% of the total variation in eHealth literacy and was deemed the best fitting model. Younger age (P=.01; 95% CI –0.12 to –0.02), lower self-reported HbA1c levels (P=.04; 95% CI –0.12 to 0.00) and higher psychosocial self-efficacy (P=<.001; 95% CI 2.68 to 4.75) were found associated with higher Sw-eHEALS scores when adjusted for demographic- and disease specific variables in this model. Well-being was not associated with eHealth literacy in this study.

Conclusions:

The demographic- and disease specific factors explained for the variation in eHealth literacy in this sample. Further studies in this area using newer eHealth literacy tools are important to validate our findings. The study highlights the importance of development and testing of interventions to improve eHealth literacy in this population for better glucose control. These eHealth literacy interventions should be tailored to meet the needs of people in varying age groups and with differing levels of psychosocial self-efficacy.
