Assessing the Impact of Visual and Audio Media on Sunscreen Use Among People of Color: Pre- and Post-Survey
Background:
Poor melanoma outcomes in people of color (POC) are attributed to a variety of factors, including healthcare literacy, socioeconomic status, and healthcare access barriers. Methods: We designed a survey to determine if visual and audio media (VAM) would increase POC's understanding of the need for sunscreen and their willingness to use it. Patients recruited at a dermatology clinic were asked to watch a 2.5-minute video on sun protection and complete a pre- and post-survey assessing their knowledge.
Results:
Forty-one (41) patients were recruited, 43.9% of whom identified as POC and 31.7% as Hispanic or Latino. In the post-survey, 100% of participants agreed that daily sunscreen use helps prevent sun-related risks, compared to 68% before (P<.0001). 71% of the participants intended to use sunscreen daily after watching the video, compared to 24% who did so before (P<.0001). One-hundred percent (100%) of Black participants in the post-survey agreed that sunscreen wear helps prevent risks associated with sun exposure, compared to 46% in the pre-survey (P= 0.0052); no significant difference among White participants (80% vs 100%; P=0.1121).
Limitations:
Small sample size, no long-term follow-up.
Conclusions:
This study demonstrates the persistence of health disparities and the effectiveness of VAM in enhancing Black patients' healthcare literacy. J Drugs Dermatol. 2024;23(7):525-528. doi:10.36849/JDD.7821.
