Derivation, Evaluation, and Validation of Illustrations of Key Counselling Points for a Pediatric Eczema Action Plan

Abstract

Background: Current eczema action plans (EAP) are based on written instructions without illustrations. Incorporating validated illustrations into EAPs can significantly improve comprehension and usability. Objective: To produce and validate a set of illustrations for key counselling points of a pediatric EAP. Methods: Illustrations were developed using key graphic elements and refined by subject experts. Illustrations were evaluated during one-on-one structured interviews with parents/caregivers of children ages 9 and younger, as well as with children ages 10 to 17 years between September 2015 and June 2016. The concepts of transparency, translucency, and short-term recall were assessed for validation. Results: Of 245 participants, 81.3% were parents and/or caregivers of children 0 to 9 years old, and 18.7% were children between 10 and 17 years old. A total of 15 illustrations and 2 storyboards were evaluated; 9 illustrations and 2 storyboards were redesigned to reach the preset validation targets. Overall, 13 illustrations and 2 storyboards were validated. Conclusion: A set of illustrations for use in an EAP was prospectively designed and validated, achieving acceptable transparency, translucency, and recall, with input from patients and a multidisciplinary medical team. The incorporation of validated illustrations into eczema action plans benefits patients with limited health literacy. Future studies should evaluate if illustrations improve understanding of eczema management and translate into improved clinical outcomes.
