Does diabetes distress influence clinical response to an mHealth diabetes self-management education and support intervention?

Purpose The purpose of this study was to examine whether baseline levels of diabetes distress (DD) impacted clinical benefit from a mobile health (mHealth) diabetes self-management education and support (DSME/S) intervention (“Dulce Digital”). Methods This secondary analysis included the full sample of 126 Hispanic adults (mean age = 48.43 years, SD = 9.80) with type 2 diabetes and glycosylated hemoglobin A1C >7.5% enrolled from a Federally Qualified Health Center in a randomized, nonblinded clinical trial that compared Dulce Digital to usual care. Dulce Digital participants received educational/motivational, medication reminders, and blood glucose monitoring prompt text messages over 6 months. Results Baseline levels of DD prospectively moderated the effect of Dulce Digital (vs usual care) on glycemic control over 6 months, such that Dulce Digital participants with higher DD experienced relatively greater benefit from the intervention. The effect of the intervention on A1C change was 178% larger among individuals experiencing moderate/high versus no/low DD. Conclusions Although research has found DD to be associated with poorer self-management and clinical outcomes, individuals already distressed about their diabetes may benefit from a lower-burden mHealth DSME/S approach.
