This study found that some older adults tend to overestimate their performance, even when their actual performance suggests otherwise. These mismatches between how older people think they are performing and how they actually perform could lead to missed chances for support or intervention if only a self-report measure is used. Using self-report followed by performance-based measures is recommended to identify late-life disability among these older adults.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.5014\/ajot.2026.051408","type":"journal-article","created":{"date-parts":[[2026,5,29]],"date-time":"2026-05-29T16:08:55Z","timestamp":1780070935000},"page":"662-669","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Discordance Between Self-Report and Performance-Based Measures Among At-Risk Older Adults: A Secondary Data Analysis"],"prefix":"10.1177","volume":"80","author":[{"given":"Chiung-ju","family":"Liu","sequence":"first","affiliation":[{"name":"Chiung-ju Liu, PhD, OTR\/L, FGSA, is Associate Professor, Department of Occupational Therapy, College of Public Health and Health Professions, University of Florida, Gainesville;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wen-Pin","family":"Chang","sequence":"additional","affiliation":[{"name":"Wen-Pin Chang, PhD, OTR\/L, is Assistant Professor, Department of Occupational Therapy, College of Health Professions, University of Texas Rio Grande Valley, Edinburg."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Inga","family":"Wang","sequence":"additional","affiliation":[{"name":"Inga Wang, PhD, OTR\/L, is Professor, Programs in Occupational Therapy Science, Technology &amp; Rehabilitation, School of Rehabilitation Sciences and Technology, University of Wisconsin-Milwaukee, Milwaukee."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2026,5,29]]},"reference":[{"key":"e_1_3_2_2_1","first-page":"7412410010","article-title":"Occupational therapy practice framework: Domain and process (4th ed.)","volume":"74","author":"American Occupational Therapy Association","year":"2020","unstructured":"American Occupational Therapy Association.
