Objectives:
To assess the readability of printed education materials (PEMs) for patients with systemic lupus erythematosus (SLE) and to explore the perceptions of patients with SLE with different health literacy regarding the readability of PEMs.
Design:
A mixed-methods study, including a cross-sectional survey and semistructured interviews.
Setting:
The SLE PEMs were collected from 13 hospitals in China. The interviews were conducted in the Department of Rheumatology of a hospital in Hefei, China.
Participants:
In the cross-sectional survey, convenience sampling was used to select the Chinese SLE PEMs, with 20 PEMs included. In the qualitative study, the patients with SLE were divided into two groups based on their health literacy. Then, purposive sampling was used to select participants in each group, with 18 patients recruited.
Outcome Measures:
The readability of PEMs was assessed by the language analysis technology and the Chinese version of the Suitability Assessment of Materials (SAM-C) instrument.
Results:
For text factors of readability, the mean Chinese language difficulty coefficient was 67.09±8.03, which indicates that the text of PEMs was difficult to read. For non-text factors, the mean SAM-C score was 45.62±9.51. Eight PEMs were rated not suitable, 12 were adequate and none were superior. In the interviews, eight categories were identified: information source, content, actionability, plain language, pictures, tables, numbers and layout. Patients with different health literacy had discrepant views on the detail of basic information, the necessity of question list, the location of functional pictures and the application of mathematical symbols.
Conclusions:
The readability of Chinese SLE PEMs does not perform well, and it is necessary to reduce the difficulty of words, shorten the length of sentences and improve the picture design and actionability. To develop PEMs tailored to patients' level of health literacy, patients' unique view of readability should be integrated into the design of PEMs.
