This study aimed at evaluating the quality and readability of online information about breast cancer written in Chinese.
An Internet search was conducted for "breast cancer" in Chinese using the Baidu search engine. Website quality was evaluated using the DISCERN instrument, and readability was evaluated using the Chinese Readability Index Explorer (CRIE). Higher DISCERN score indicated higher quality of websites, while higher CRIE score indicated lower readability of the content of the websites. We also investigated the effects of website producer category, and the associations of search engine ranking with DISCERN and CRIE scores.
A total of 49 websites were included. The mean overall DISCERN score was 50.27 ± 4.14, and the mean CRIE score was 6.78 ± 0.16. Websites produced by non-profit organizations had the highest overall DISCERN scores, while those produced by private individuals had the lowest CRIE scores. Search engine ranking had no significant correlation with website quality or readability.
The quality and readability of breast cancer websites in Chinese were not satisfactory, and they varied among different website producer categories.
Website producers should seek to provide more accurate, comprehensive, and easy-to-understand information to better meet the needs of breast cancer patients. In addition, search engines should revise algorithms to promote websites with higher quality and accessibility.
本研究旨在评估中文撰写的乳腺癌在线信息的质量和可读性。
使用百度搜索引擎对中文的“乳腺癌”进行了互联网搜索。使用 DISCERN 工具评估网站质量，使用中文阅读难度指数探索器（CRIE）评估可读性。DISCERN 评分越高表示网站质量越高，而 CRIE 评分越高表示网站内容的可读性越低。我们还调查了网站制作方类别和搜索引擎排名对 DISCERN 和 CRIE 评分的影响。
共纳入 49 个网站。总体 DISCERN 评分的平均值为 50.27±4.14，CRIE 评分的平均值为 6.78±0.16。非盈利组织制作的网站总体 DISCERN 评分最高，而个人制作的网站 CRIE 评分最低。搜索引擎排名与网站质量或可读性均无显著相关性。
中文乳腺癌网站的质量和可读性均不理想，且在不同的网站制作方类别之间存在差异。
网站制作方应努力提供更准确、全面且易于理解的信息，以更好地满足乳腺癌患者的需求。此外，搜索引擎应修改算法，以推广质量更高且更易获取的网站。
