Background Adherence to daily inhaled corticosteroid medication is important for asthma control but low health literacy is a barrier to comprehension of control status and may contribute to medication nonadherence. Infographics tailored with patients' own data can support comprehension of health status, but these have not been applied to asthma successfully. Objectives This two-phased study developed and tested tailored infographics of (1) scores on the Asthma Control Questionnaire (ACQ), a self-report measure of symptom burden, and (2) pulmonary function test (PFT) results. The infographics are intended for use as communication and adherence-promotion tools in clinical interactions. Methods For both phases, participants (18+ years, English- or Spanish-speaking, persistent asthma) were recruited through two primary care clinics. In Phase I, we used a hybrid iterative participatory design process to refine prototype designs. In Phase II, we conducted individual comprehension assessment interviews with the finalized designs. Infographics were hand-tailored for each participant using their ACQ score and PFT results collected at the start of the interview. Two independent raters scored interview transcripts for gist and verbatim comprehension based on a predetermined rubric. Results The five Phase I design sessions led to final prototypes that participants (n = 21) considered appealing and easy to comprehend. All Phase II participants (n = 10) demonstrated complete gist and verbatim comprehension. Participants reacted favorably to receiving their information via infographics and expressed intentions to engage in self-management behaviors (e.g., medication adherence, smoking cessation, weight loss, and review of their care plan) in response to the information. Conclusion This study provides preliminary evidence that infographics can support comprehension of asthma control status and promote self-management intentions among adults with persistent asthma. Infographics can be programmed into electronic health records and/or standalone applications to allow for instant tailoring at the point of care.

“…Research by Hancock, Rogers, Schroeder, and Fisk (2004) and Brantley and Wogalter (1999) addressed this concern by proposing methods that would elicit additional responses from participants. Hancock, et al proposed a phrase generation method for testing safety symbols in which participants would prepare a list of phrases based on their understanding of the symbol.…”

This study compares methods for testing comprehension of a set of three safety symbols -in-person questionnaire administration and three variations of a web-based questionnaire using similar protocols. Both the medium and the particular questions asked were varied. The in-person method included follow-up and probing questions and used questions about the individual symbols only if needed to elicit complete answers. The web-based questionnaires omitted follow-up and probing questions, and always included questions about the individual symbols. The second variation of the web-based questionnaire added an example of a "good/poor answer" as shown in ANSI Z535.3 Annex B. The third included the example answer and an additional question regarding consequences. The in-person method measured 90% correct comprehension with 2% critical confusions. Comprehension measured by each of the three web-based methods did not significantly differ from the in-person method. The comparison of different web-based questionnaires indicates that for web-based testing, asking about individual symbols within a symbol set, providing an example of a good/poor answer, and/or including an additional question regarding consequences can improve the method's ability to capture comprehension data. These results suggest that under some circumstances, a web-based questionnaire could substitute for in-person comprehension testing.
