The Oral Frailty Index\u20108 (OFI\u20108) is a brief self\u2010report screening tool for assessing oral frailty. This study's aim is to adapt the OFI\u20108 into Turkish (OFI\u20108\u2010TR) and evaluate its psychometric properties among older adults.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>A cross\u2010sectional study was conducted in 341 adults aged \u2265\u200965\u2009years attending a geriatrics outpatient clinic. Internal consistency (KR\u201020), test\u2013retest reliability (ICC), and construct validity (convergent, known\u2010groups, and confirmatory factor analyses) were evaluated. Comparator measures included the FRAIL (Fatigue, Resistance, Ambulation, Illnesses, and Loss of weight) scale, Clinical Frailty Scale (CFS), Eating Assessment Tool\u201010 (EAT\u201010), Functional Oral Intake Scale (FOIS), and Mini Nutritional Assessment\u2013Short Form (MNA\u2010SF).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      The OFI\u20108\u2010TR showed acceptable internal consistency (KR\u201020\u2009=\u20090.62) and excellent test\u2013retest reliability (ICC\u2009=\u20090.898). Confirmatory factor analysis supported a one\u2010factor model (Comparative Fit Index (CFI)\u2009=\u20090.93, Goodness\u2010of\u2010Fit Index (GFI)\u2009=\u20090.95, adjusted Goodness\u2010of\u2010Fit Index (AGFI)\u2009=\u20090.91).
