Reliability was assessed using internal consistency, item analysis, and test\u2013retest reliability.

Items 7 and 8 were excluded due to poor content validity, increasing the reliability of the final 32-item scale (\u03b1\u202f=\u202f0.876, \u03c9\u202f=\u202f0.867). PCA revealed a two-factor solution accounting for 30% of the total variance. Known-groups analyses showed significant differences in KAOP-D-32 scores according to gender, age group, educational level, and self-reported attitudes toward older adults. The final KAOP-D-32 total scores showed a significant correlation with the ASD (\n                      <jats:italic>r<\/jats:italic>\n                      \u202f=\u202f\u22120.40). Most AS and FS domains correlated significantly with KAOP-D32, except finances. Furthermore, higher KAOP-D-32 scores were associated with older age, better self-rated health, and greater life satisfaction.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>These results support that the KAOP-D-32 is a psychometrically robust instrument for assessing attitudes toward older adults.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.3389\/fpsyg.2026.1916164","type":"journal-article","created":{"date-parts":[[2026,8,25]],"date-time":"2026-08-25T13:52:11Z","timestamp":1787665931000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":1,"title":["Psychometric properties of the Kogan Attitudes toward Older People Scale: evidence from a German general-population survey"],"prefix":"10.3389","volume":"17","author":[{"given":"Birgit","family":"Teichmann","sequence":"first","affiliation":[{"name":"Network Aging Research, Heidelberg University","place":["Heidelberg, Germany"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fany","family":"Pegiou","sequence":"additional","affiliation":[{"name":"Network Aging Research, Heidelberg University","place":["Heidelberg, Germany"]},{"name":"Nursing Department, International Hellenic University","place":["Thessaloniki, Greece"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shengze","family":"Zhi","sequence":"additional","affiliation":[{"name":"Network Aging Research, Heidelberg University","place":["Heidelberg, Germany"]},{"name":"School of Nursing, Jilin University","place":["Changchun, Jilin, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Burcu","family":"Akpinar S\u00f6ylemez","sequence":"additional","affiliation":[{"name":"Network Aging Research, Heidelberg University","place":["Heidelberg, Germany"]},{"name":"Department of Internal Medicine Nursing, Faculty of Nursing, Dokuz Eylul University","place":["Inciralti, Izmir, T\u00fcrkiye"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2026,8,25]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","first-page":"47","DOI":"10.1186\/s12912-023-01195-y","article-title":"Evaluating knowledge and attitudes scales for the care of older adults among nursing students in Ghana","volume":"22","author":"Abudu-Birresborn","year":"2023","journal-title":"BMC Nurs."},{"key":"ref2","doi-asserted-by":"publisher","first-page":"1518","DOI":"10.1093\/ije\/dyy094","article-title":"Comparison of cognitive and physical functioning of Europeans in 2004-05 and 2013","volume":"47","author":"Ahrenfeldt","year":"2018","journal-title":"Int.
