Short testimonial videos to encourage diabetic eye screening in Latinx communities
Development of a Culturally Adapted, Video-based Patient Education Intervention to Increase Diabetic Eye Screening and Teleophthalmology Use in Latinx Communities
This project will test whether short Spanish-language testimonial videos from Latinx patients, Latinx clinicians, or both can increase eye health knowledge, trust, and willingness to use teleophthalmology among Latinx adults with diabetes.

What this trial studies
Investigators will record brief video testimonials from three Latinx patients with diabetes and three Latinx clinicians, conducted in Spanish with English subtitles, using prompts to elicit key culturally relevant messages. A bilingual community outreach specialist will lead four stakeholder meetings to adapt these testimonials into culturally tailored patient-education videos. An online randomized survey of 1,500 self-identified Hispanic/Latino adults will then compare three video conditions (patient+clinician, patient-only, clinician-only) against two controls (a standard National Eye Institute video and a questionnaire-only control) using pre- and post-measures in a mixed-effects design. Outcomes include changes in eye health literacy, trust in care, and intentions to use teleophthalmology for diabetic eye screening.
Who should consider this trial
Good fit: Ideal participants are Latinx adults with diabetes—survey participants simply need to self-identify as Hispanic/Latino, while those who record testimonials or attend stakeholder meetings should be Latinx patients or clinicians affiliated with Access Community Health Centers or UW Health in Madison, WI.
Not a fit: Patients who are not Latinx, who already receive regular diabetic eye screening, or who lack internet access to view online videos are unlikely to benefit from this intervention.
Why it matters
Potential benefit: If successful, the videos could increase screening uptake and earlier detection of diabetic retinopathy by improving understanding and trust in teleophthalmology among Latinx patients.
How similar studies have performed: Teleophthalmology programs and culturally tailored educational videos have improved screening rates in prior work, though combining patient-plus-clinician testimonial videos specifically for Latinx communities is a relatively novel approach.
