Evaluate the quality and readability of United Kingdom-based websites on anorexia nervosa.
First-page search results of three search engines (with search term "anorexia nervosa") were consulted. Websites were excluded if they were pro-ana, duplications, advertisements, Wikipedia, nonwritten/video, invalid addresses, non-English, book links, articles/news pages, and discussion forums. Fifteen websites were evaluated on information quality using DISCERN, and on readability using the Flesch Reading Ease (FRE) Scale. Spearman's correlations between quality and readability were calculated.
DISCERN-scores ranged from 34 to 71 (M = 49.27, SD = 9.16), representing "fair" information quality. FRE-scores ranged from 28 to 64 (M = 42.7, SD = 13.43), representing "difficult" readability. The Royal College of Psychiatrists website (https://www.rcpsych.ac.uk/) received the only "excellent" quality rating and was the only website that met the recommended reading level. The other websites' quality varied, and their reading levels ranged from fairly to very difficult.
Website quality scores varied. Oftentimes, information about treatment risks and benefits was lacking, and texts were too complex. Website quality seals could prove beneficial, and web developers should use quality and readability measures to ensure information accessibility. Future research should utilize DISCERN and FRE to evaluate quality and readability of websites pertaining to other eating disorders too.

评估英国关于神经性厌食症的网站的质量和可读性。
首先咨询了三个搜索引擎（搜索词为“神经性厌食症”）的第一页搜索结果。如果网站是支持神经性厌食症的、重复的、广告、维基百科、非书面/视频、无效地址、非英语、书籍链接、文章/新闻页面和讨论论坛，则将其排除在外。使用 DISCERN 评估了 15 个网站的信息质量，使用 Flesch 阅读舒适度（FRE）量表评估了可读性。计算了质量和可读性之间的 Spearman 相关性。
DISCERN 评分范围为 34 至 71（M = 49.27，SD = 9.16），代表“公平”的信息质量。FRE 评分范围为 28 至 64（M = 42.7，SD = 13.43），代表“困难”的可读性。皇家精神病学院网站（https://www.rcpsych.ac.uk/）获得了唯一的“优秀”质量评级，是唯一符合推荐阅读水平的网站。其他网站的质量参差不齐，阅读水平从相当难到非常难不等。
网站质量评分各不相同。通常，关于治疗风险和益处的信息缺乏，而且文本过于复杂。网站质量印章可能会很有帮助，并且网站开发人员应该使用质量和可读性措施来确保信息的可访问性。未来的研究应该使用 DISCERN 和 FRE 来评估其他饮食失调症相关网站的质量和可读性。视频摘要：https://www.youtube.com/watch?v=a9DKS7qISSA&feature=youtu.be。
