Study Description

Brief Summary

Mounting evidence documents the positive impact of using patient decision aids (PtDA) to facilitate shared decision-making (SDM) between patients and physicians in preference sensitive contexts. But overall use of PtDAs across the broader US healthcare system remains low. More compelling evidence is needed to make the case for policies that would accelerate adoption of PtDAs in routine clinical practice in primary care settings that serve diverse and economically disadvantaged populations. The investigators believe that it is now time to move beyond the subjective evaluations of PtDAs that are commonly reported in clinical trials of PtDAs, to evaluate whether these tools can also change health behavior and improve health outcomes. Therefore, the investigators will build on their expertise in working with community-based physicians to evaluate a newly developed PtDA focused on diabetes, using a mixed-methods approach. The investigators patient sample will be drawn from primary care practices serving African American, Latino and Caucasian patients. The investigators will conduct a 2-group randomized controlled trial to evaluate the effects of the diabetes PtDA, combined with telephone coaching, in increasing patient self-care and self-efficacy, increasing diabetes knowledge and improving clinical measures including glycosylated hemoglobin A1c, lipids and blood pressure. The investigators will also explore variation in effects of the patient decision aid, comparing African American, Latino and Caucasian patients and conduct in-depth interviews with a randomly selected subset of trial participants to explore patient perceptions of the decision aid and variation across racial/ethnic groups. The investigators hypothesize that, compared to the control condition, participants assigned to receiving the video PtDA program and telephone coaching will report: greater self-efficacy and diabetes knowledge, more engagement in self-care behaviors, better glycemic control as measured by hemoglobin A1c, as well as lower quantitative LDL and blood pressure levels. The conceptual model guiding the investigators trial is the Integrative

Model of Behavior Change. The model includes three primary determinants of behavior:
  1. attitudes toward performing the behavior

  2. perceived social norms about performing the behavior

  3. self-efficacy. The investigators expect the diabetes PtDA to affect each of these constructs directly or indirectly.

Arms and Interventions

Arm Intervention/Treatment
Experimental: 1

Behavioral: Patient video decision aid & telephone coaching
The decision aid is a 30 minute video program that educates patients about their role in diabetes care. Telephone coaching will assist patients in initiating behavior change.

Active Comparator: 2

Behavioral: Printed educational brochure
The printed brochure is an educational brochure developed by the NIH.
