This demographic shift poses significant challenges for urban planning and public health, as older adults face barriers to accessing essential services and engaging in their communities. This study assesses the age-friendliness of urban environments in Indonesia by evaluating the psychometric properties of an Indonesian-language version of the Age-Friendly Cities and Communities Questionnaire (AFCCQ) and comparing perceived age-friendliness across urban categories.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec id=\"sec002\">\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>A cross-sectional survey using the Indonesian version of the AFCCQ was conducted between 7 January and 3 February 2025. The AFCCQ covers nine domains: housing, social participation, respect and social inclusion, civic participation and employment, communication and information, community support and health services, outdoor spaces and buildings, transportation, and financial status. Validity was assessed using item\u2013total Spearman correlations and exploratory factor analysis; reliability was assessed using Cronbach\u2019s \u03b1. Differences in domain scores across five urban categories were examined using the Kruskal\u2013Wallis test with Bonferroni adjustment across the nine domain-level tests (\u03b1\u2009=\u20090.05\/9\u2009=\u20090.0056).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec id=\"sec003\">\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The study involved 505 community-dwelling older adults aged \u226560 years, with a mean age of 69.4 years; 81.6% were female. The average AFCCQ score was 14.96\u2009\u00b1\u200910.46. Overall Cronbach\u2019s \u03b1 was 0.90. The KMO value was 0.83 and Bartlett\u2019s test was significant (\u03c7\u00b2(253) = 13,374.41, p\u2009&lt;\u20090.001); the first unrotated component accounted for 35.92% of the variance, although 7 components had eigenvalues greater than 1. Nominally significant differences across city categories were observed in housing, social participation, and transportation (p\u2009&lt;\u20090.05); none remained significant after Bonferroni adjustment for nine domain-level comparisons. These comparisons are reported as exploratory.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec id=\"sec004\">\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>The study indicates that the Indonesian AFCCQ has acceptable internal consistency. Item-level convergence was weak for the two respect and social inclusion items, and the exploratory factor analysis did not reproduce the nine-domain structure. Exploratory differences across urban categories suggest that perceived age-friendliness may vary by city size, particularly for housing, social participation, and transportation, and provide a basis for further investigation in representative samples. Confirmatory factor analysis and formal test\u2013retest assessment in an independent Indonesian sample remain necessary.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1371\/journal.pone.0358251","type":"journal-article","created":{"date-parts":[[2026,10,8]],"date-time":"2026-10-08T17:41:41Z","timestamp":1791481301000},"page":"e0358251","update-policy":"https:\/\/doi.org\/10.1371\/journal.pone.corrections_policy","source":"Crossref","is-referenced-by-count":0,"title":["Assessing age-friendly urban environments in Indonesia: Validation of the Indonesian age-friendly cities and communities questionnaire (AFCCQ) and differences across urban city categories"],"prefix":"10.1371","volume":"21","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6063-8319","authenticated-orcid":true,"given":"Nina Kemala","family":"Sari","sequence":"first","affiliation":[{"name":"Dr. Cipto Mangunkusumo National Referral Hospital","place":["Jakarta, Indonesia"],"department":["Geriatric Division, Department of Internal Medicine"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stepvia","family":"Stepvia","sequence":"additional","affiliation":[{"name":"Dr. Cipto Mangunkusumo National Referral Hospital","place":["Jakarta, Indonesia"],"department":["Geriatric Division, Department of Internal Medicine"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0176-9773","authenticated-orcid":true,"given":"Muhana Fawwazy","family":"Ilyas","sequence":"additional","affiliation":[{"name":"Universitas Sebelas Maret","place":["Surakarta, Indonesia"],"department":["Faculty of Medicine"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"340","published-online":{"date-parts":[[2026,10,8]]},"reference":[{"key":"pone.0358251.ref001","author":"World Health Organization","year":"2024"},{"issue":"1","key":"pone.0358251.ref002","doi-asserted-by":"crossref","first-page":"336","DOI":"10.1186\/s12877-019-1355-0","article-title":"Development and validation of elder-friendly urban spaces questionnaire (EFUSQ)","volume":"19","author":"A Lak","year":"2019","journal-title":"BMC Geriatr"},{"issue":"16","key":"pone.0358251.ref003","doi-asserted-by":"crossref","DOI":"10.3390\/ijerph18168290","article-title":"Active aging in ASEAN countries: Influences from age-friendly environments, lifestyles, and socio-demographic factors","volume":"18","author":"S Tiraphat","year":"2021","journal-title":"Int J Environ Res Public Health"},{"key":"pone.0358251.ref004","doi-asserted-by":"crossref","first-page":"2050312119852510","DOI":"10.1177\/2050312119852510","article-title":"Developing age-friendly city readiness: A case study from Depok City, Indonesia","volume":"7","author":"F Fatmah","year":"2019","journal-title":"SAGE Open Med"},{"issue":"3","key":"pone.0358251.ref005","doi-asserted-by":"crossref","first-page":"250","DOI":"10.1080\/08959420.2019.1589889","article-title":"What prompts policy change?
