Translation, Cross-Cultural Adaptation, and Validation of the Japanese Version of the Patient Education Materials Assessment Tool (PEMAT)

Abstract

The Patient Education Materials Assessment Tool (PEMAT) systematically evaluates the understandability and actionability of patient education materials. This study aimed to develop a Japanese version of PEMAT and verify its reliability and validity. After assessing content validation, experts scored healthcare-related leaflets and videos according to PEMAT to verify inter-rater reliability. In validation testing with laypeople, the high-scoring material group (n = 800) was presented with materials that received high ratings on PEMAT, and the low-scoring material group (n = 799) with materials that received low ratings. Both groups responded to the understandability and actionability of the materials and perceived self-efficacy for the recommended actions. The Japanese version of PEMAT showed strong inter-rater reliability (PEMAT-P: % agreement = 87.3, Gwet's AC1 = 0.83. PEMAT-A/V: % agreement = 85.7, Gwet's AC1 = 0.80). The high-scoring material group had significantly higher scores for understandability and actionability than the low-scoring material group (PEMAT-P: understandability 6.53 vs. 5.96, p < 0.001; actionability 6.04 vs. 5.49, p < 0.001; PEMAT-A/V: understandability 7.65 vs. 6.76, p < 0.001; actionability 7.40 vs. 6.36, p < 0.001). Perceived self-efficacy increased more in the high-scoring material group than in the low-scoring material group. Our study showed that materials rated highly on Japanese version of PEMAT were also easy for laypeople to understand and action.
