Responses were recorded in Microsoft Word and reviewed by 2 raters for their accuracy and completeness. Readability of content was determined by pasting responses into a web-based Flesch Kincaid Reading Ease Scores calculator.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n Responses to all questions were accurate and culturally appropriate. In total, 17 of the 23 questions (74%) had complete responses. The average readability of responses was 64.5 (SD 8.7; written at an 8th-grade level).<\/jats:p>\n <\/jats:sec>\n \n Conclusions<\/jats:title>\n Generative AI chatbots, such as Prostate Cancer Info, are great starting places for learning about PrCA screening and preparing men to engage in shared decision-making but should not be used as independent sources of PrCA information because key information may be omitted. Men are encouraged to use these tools to complement information received from a health care provider.<\/jats:p>\n <\/jats:sec>","DOI":"10.2196\/72522","type":"journal-article","created":{"date-parts":[[2025,4,21]],"date-time":"2025-04-21T02:25:06Z","timestamp":1745202306000},"page":"e72522-e72522","source":"Crossref","is-referenced-by-count":6,"title":["Evaluating an AI Chatbot \u201cProstate Cancer Info\u201d for Providing Quality Prostate Cancer Screening Information: Cross-Sectional Study"],"prefix":"10.2196","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1023-1449","authenticated-orcid":false,"given":"Otis L","family":"Owens","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0003-6686-5656","authenticated-orcid":false,"given":"Michael S","family":"Leonard","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1010","published-online":{"date-parts":[[2025,5,21]]},"reference":[{"key":"R1","unstructured":"How ChatGPT and our foundation models are developed.
