A mobile app for chronic disease self-management for individuals with low health literacy: A multisite randomized controlled clinical trial

Abstract

AbstractObjectiveThe purpose of this study was to evaluate the effects of a mobile app designed to improve chronic disease self-management in older adult patients with low health literacy and who had at least one chronic health condition, and to assess the impact of delivering information at different levels of reading difficulty.MethodsA randomized controlled trial was completed at two sites. Individuals 40 years of age and older screened for low health literacy who had at least one chronic health condition were randomly assigned to a tailored information multimedia app with text at one of three grade levels. Four primary outcomes were assessed: patient activation, chronic disease self-efficacy, health-related quality of life, and medication adherence.ResultsAll groups showed overall increases in activation, self-efficacy, and health-related quality of life, but no change in medication adherence. No between-group differences were observed.ConclusionsThe mobile app was effective in increasing participants’ levels of several psychosocial variables, but reading difficulty level was not significantly related to outcomes.Registered atclinicaltrials.govNCT02922439.
