Background: Saudi Arabia has the second-highest prevalence of diabetes in the Middle East. Therefore, providing patients with high-quality materials is essential to help them understand their illness. The Patient Education Materials Assessment Tool (PEMAT) contrasts and evaluates materials regarding understandability and actionability. Purpose: This study aimed to evaluate materials for type 2 diabetes using a printed version of the PEMAT. Methods: This observational study was conducted in Riyadh from December 2022 to May 2023. Sixty-nine samples were collected from hospitals affiliated with the Ministry of Health and the government sector. Results: Materials evaluated in this study had an excellent understandability score of 78.9% and a low actionability score of 66.6%, with significant differences between the sources. Some of the materials (42%) achieved high quality regarding understandability and actionability. Discussion: Less than half of the materials were considered high quality. Approximately 99% of the materials made their purposes completely evident and logically presented the information, and approximately 97% identified at least one action. However, only 17.4% of the materials provided summaries and tangible tools. Translation to Health Education Practice: Health Educators should consider including summaries and tangible tools when developing patient education materials to make them more understandable and actionable.
