Digital Storytelling Intervention for Hemoglobin A 1c Control Among Hispanic Adults With Type 2 Diabetes: A Randomized Clinical Trial
Authors' conclusion
In this randomized clinical trial, a digital storytelling intervention developed with and for Hispanic adults with T2D was highly acceptable and feasibly implemented within primary care settings and resulted in a modest improvement of glycemic control. This was a highly scalable intervention that may be integrated into clinical practice as part of a longitudinal diabetes self-management program for Hispanic adults.
