E-Learning Material of Evidence-Based Medicine for Laypersons.

Background: There is a need for evidence-based medicine (EBM) education for laypersons. However, there are few materials or opportunities to learn EBM for Japanese laypersons.

Objective: The aim of this study was to develop and test the usability of e-learning material on EBM for health-conscious laypersons in Japan.

Methods: This study was conducted in two steps. First, content elements for the material were identified using purposive evaluation and a prototype of the e-learning material was developed. Following this, usability testing of the material was conducted. A questionnaire survey and qualitative semi-structured focus group interviews were conducted with health-conscious laypersons. Subsequently, the material was refined and finalized.

Key results: A total of 217 descriptions related to EBM were extracted from 12 materials and were integrated into 56 major elements. Each element was rated from the viewpoint of usefulness for laypersons and reviewed by four expert panelists, and finally 18 elements were confirmed, most of which were critical appraisal skills related to critical health literacy. For the usability testing after constructing the material, 25 laypersons participated, and 19 (76%) felt very/rather much interest in the contents of the material in the questionnaire. The results of five focus group interviews showed that the effectiveness of the e-learning material was influenced by the story and characters, and whether the contents of the material were consistent with interviewees' daily interests.

Conclusions: The e-learning material on EBM was found to be of interest to health-conscious laypersons and appeared to be useful in participants' daily lives. This study successfully developed novel e-learning material on the essential components of EBM for laypersons in Japan.

Most of the contents of the material are related to critical health literacy. The usability testing showed that the material was of interest to non-health professionals and useful for dealing with health information in their daily lives.
