Overview
Brief Summary
Latino individuals, the fastest growing ethnic minority population in the United States, have a higher prevalence of type 2 diabetes and diabetes-related complications, and are more likely to report inconsistent use of diabetes medications than non-Hispanic White individuals. The proposed project will test an interactive text message-based tool tailored to address barriers to taking diabetes medications that are relevant to Latino adults. If found feasible, acceptable, and usable, this intervention could serve as a scalable tool to improve diabetes management and reduce diabetes-related complications among Latino adults in the United States.
Detailed Description
Latino adults have a disproportionate burden of type 2 diabetes and diabetes-related complications. Diabetes medication non-adherence is an important modifiable contributor to suboptimal glycemic management among Latino adults, who are nearly twice as likely to report non-adherence to diabetes medications as non-Hispanic White individuals. Besides language barriers, additional commonly reported barriers that contribute to non-adherence in this population include negative perceptions about insulin use and misunderstanding ongoing need for diabetes medications once HbA1c has improved. Mobile health (mHealth) technology can reduce medication adherence barriers and improve adherence behavior, but mHealth tools that address commonly reported barriers to diabetes medication adherence among Latino adults are lacking. One such mHealth platform is REACH (Rapid Encouragement/Education And Communications for Health), a text message-based tool that improved diabetes medication adherence and glycemic control among English-speaking adults with type 2 diabetes. This study will evaluate REACH-Español (hereafter "REACH-Es), an mHealth platform adapted from the original REACH intervention that will incorporate qualitative input from Latino adults with type 2 diabetes on barriers to diabetes medication adherence relevant to this population. Specifically, the investigators will conduct a pilot RCT (n=70) to assess feasibility, acceptability, and usability of REACH-Es, as well as intervention targets (diabetes medication adherence and barriers to adherence) comparing REACH-Es to enhanced treatment as usual; secondary outcomes are HbA1c and diabetes self- efficacy. The project will generate preliminary data for an R01 hybrid-effectiveness implementation trial of REACH-Es.

- •Willing and able to provide informed consent
- •Access to a mobile telephone with text messaging capability
- •Suboptimal diabetes medication adherence, assessed using the first 2 items in the Adherence to Refill and Medication Scale (ARMS-d) questionnaire combined: "How frequently do you forget or decide to not take your diabetes medications?" Participants who answer sometimes, almost always, and/or always will be considered eligible for the study.

Outcomes
Primary Outcomes
Diabetes Medication adherence
Time Frame: Collected at 0, 3, and 6 months
Assessed using the 11-item Adherence to Refill and Medication Scale (ARMS-d) questionnaire scored on a 0-4 Likert scale (range 12-48).
Feasibility (recruitment rate)
Time Frame: Collected at 0 months
Number of eligible participants who enroll/ Number of eligible participants who are contacted and reached by phone
Feasibility (response rate to 2-way text messages)
Time Frame: Collected at 3 and 6 months
Number of 2-way text messages answered/ Number of 2-way text messages received
Acceptability
Time Frame: Collected at 3 and 6 months
Assessed quantitatively based on utility of REACH-Es on a 0-10 Likert scale and qualitatively through exit interviews.
Feasibility (retention rate)
Time Frame: Collected at 3 and 6 months
Number of participants enrolled in the study at follow-up/ Number of participants enrolled at the start of the study
Usability
Time Frame: Collected at 3 and 6 months
Assessed quantitatively by administering the 10-item Spanish version of the System Usability Scale (SUS) questionnaire, scored on a 0-5 Likert-type scale.
IMB barrier sum score
Time Frame: Collected at 0, 3, and 6 months
Calculated by rating each barrier item on a 0-10 scale (1=never to 10=a lot) and identifying each participant's 4 highest- scored barriers (range 4-40).
Secondary Outcomes
- HbA1c(Collected at 0, 3, and 6 months)
- Diabetes self-efficacy(Collected at 0, 3, and 6 months)
