This study examined the psychometric properties of a revised HIV and PrEP knowledge instrument for young sexual and gender minority (SGM) men. Data were collected from 1,519 participants (ages 17\u201329) via an online survey. Of the original 31 items, 7 were removed based on item analysis, and Exploratory Factor Analysis (EFA) was conducted on the remaining 24 items. EFA supported a two-factor structure\u201418 items assessing general HIV knowledge and 6 assessing PrEP knowledge\u2014with acceptable model fit (RMSEA = 0.06) and strong factor loadings (0.32). The instrument demonstrated measurement invariance across major racial\/ethnic groups, moderate to strong item-total correlations (\u22650.30), and acceptable internal consistency for both subscales. Findings validate this 24-item, two-factor instrument as a reliable tool for assessing HIV and PrEP knowledge among SGM men.<\/jats:p>","DOI":"10.1521\/aeap.2026.38.1.47","type":"journal-article","created":{"date-parts":[[2026,2,26]],"date-time":"2026-02-26T16:23:35Z","timestamp":1772123015000},"page":"47-62","source":"Crossref","is-referenced-by-count":0,"title":["Psychometric Evaluation of a Revised Instrument for Assessing HIV Knowledge Among SGM Men"],"prefix":"10.1521","volume":"38","author":[{"given":"Ching-Yu","family":"Wang","sequence":"first","affiliation":[{"name":"School of Nursing, Columbia University, New York, New York."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jianfang","family":"Liu","sequence":"additional","affiliation":[{"name":"School of Nursing, Columbia University, New York, New York."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Se Hee","family":"Min","sequence":"additional","affiliation":[{"name":"School of Nursing, University of Pennsylvania, Philadelphia, Pennsylvania."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dustin T.","family":"Duncan","sequence":"additional","affiliation":[{"name":"Department of Epidemiology, Mailman School of Public Health, Columbia University."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lisa M.","family":"Kuhns","sequence":"additional","affiliation":[{"name":"Division of Adolescent & Young Adult Medicine, Ann & Robert H.
