Evaluation, Modification and Validation of a Set Of Asthma Illustrations in Children with Chronic Asthma in the Emergency Department
OBJECTIVES: To test, modify and validate a set of illustrations depicting different levels of asthma control and common asthma triggers in pediatric patients (and/or their parents) with chronic asthma who presented to the emergency department at the Children’s Hospital of Eastern Ontario, Ottawa, Ontario.METHODS: Semistructured interviews using guessability and translucency questionnaires tested the comprehensibility of 15 illustrations depicting different levels of asthma control and common asthma triggers in children 10 to 17 years of age, and parents of children one to nine years of age who presented to the emergency department. Illustrations with an overall guessability score <80% and/or translucency median score <6, were reviewed by the study team and modified by the study’s graphic designer. Modifications were made based on key concepts identified by study participants.RESULTS: A total of 80 patients were interviewed. Seven of the original 15 illustrations (47%) required modifications to obtain the prespecified guessability and translucency goals.CONCLUSION: The authors successfully developed, modified and validated a set of 15 illustrations representing different levels of asthma control and common asthma triggers.PRACTICE IMPLICATIONS: These illustrations will be incorporated into a child-friendly asthma action plan that enables the child to be involved in his or her asthma self-management care.
