However, its implementation remains limited by a shortage of geriatric specialists, the complexity of geriatric care, and the increasing demands of an aging population. Mobile self-administered tools offer a potential strategy to expand access to multidimensional geriatric evaluation, particularly in resource-limited settings.<\/jats:p>\n <\/jats:sec>\n \n Objective<\/jats:title>\n This study aimed to evaluate the feasibility and agreement of a mobile self-administered CGA screening tool compared with geriatrician-administered assessments among inpatient and outpatient older adults in Brazil.<\/jats:p>\n <\/jats:sec>\n \n Methods<\/jats:title>\n This cross-sectional study included 80 older adults recruited from inpatient and outpatient geriatric clinics in Bras\u00edlia, Brazil. Participants completed a mobile CGA, which incorporated validated instruments covering functional status (Vulnerable Elders Survey\u201313 [VES-13]), cognition (Cognitive Change Questionnaire\u20138 [CCQ-8]), depressive symptoms (5-item Geriatric Depression Scale [GDS-5]), nutritional status (Mini Nutritional Assessment [MNA]), frailty (G8 screening tool), social support (Gij\u00f3n Scale), falls, and vision and hearing. Within 48 hours, a geriatrician independently performed a geriatrician-administered CGA using the same instruments. Agreement between the 2 assessment methods was evaluated using Wilcoxon signed-rank tests, Spearman correlation coefficients, intraclass correlation coefficients (ICCs), and Cohen \u03ba coefficients for categorical variables.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n \n Participants had a mean age of 70 (SD 7) years; 58.8% (47\/80) were female, and 65% (52\/80) had \u22648 years of education. The mean completion time for the self-administered CGA was 18.5 (SD 7.5) minutes. Most participants rated the tool as easy or very easy to use (65\/80, 81.3%) and reported satisfaction with the assessment process (n=79, 98.8%). High concordance was observed between the self-administered and geriatrician-administered CGA versions for most domains. Cohen \u03ba coefficients demonstrated strong agreement for falls (\u03ba=0.878;\n P<\/jats:italic>\n <.001), hearing impairment (\u03ba=0.826), and vision impairment (\u03ba=0.634). No significant differences were observed between the 2 assessment methods for functional status (VES-13), frailty screening (G8), depressive symptoms (GDS-5), and cognition (CCQ-8). Nutritional status and social vulnerability showed lower concordance than other CGA domains. Among inpatients, significant discrepancies were identified in both nutritional scores and Gij\u00f3n social risk scores (\n P<\/jats:italic>\n \u2264.05), with participants reporting greater perceived vulnerability. For outpatients, significant differences were observed for nutritional status (MNA; P=.02) and frailty screening (G8; P=.046).\n <\/jats:p>\n <\/jats:sec>\n \n Conclusions<\/jats:title>\n A mobile self-administered CGA demonstrated good feasibility, high user satisfaction, and substantial agreement with geriatrician-administered assessments across multiple geriatric domains. The tool may support geriatric screening and triage in settings with limited specialist availability, particularly when used as a complement to comprehensive clinical assessment.<\/jats:p>\n <\/jats:sec>","DOI":"10.2196\/90863","type":"journal-article","created":{"date-parts":[[2026,9,21]],"date-time":"2026-09-21T17:14:31Z","timestamp":1790010871000},"page":"e90863-e90863","source":"Crossref","is-referenced-by-count":0,"title":["Agreement Between a Mobile Self-Administered Comprehensive Geriatric Assessment Screening Tool and Geriatrician-Administered Assessment: Cross-Sectional Feasibility Study"],"prefix":"10.2196","volume":"10","author":[{"ORCID":"https:\/\/orcid.org\/0009-0004-1089-7090","authenticated-orcid":false,"given":"Daniele Fabrino","family":"Cupertino Queirod De Oliveira","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7594-969X","authenticated-orcid":false,"given":"Ana Paula","family":"Cupertino","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0003-5711-2505","authenticated-orcid":false,"given":"Samara Morais","family":"Silveira","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0008-3593-1610","authenticated-orcid":false,"given":"Rebeca Costa","family":"Barbosa","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Leonardo","family":"Spencer de Vasconcellos","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6465-356X","authenticated-orcid":false,"given":"Luiz S\u00e9rgio","family":"Fernandes","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1010","published-online":{"date-parts":[[2026,9,21]]},"reference":[{"key":"R1","doi-asserted-by":"crossref","unstructured":"Bloom DE Luca DL .
