A key barrier to identifying affected individuals is the lack of brief screening tools suitable for clinical settings. The objective of this research is to validate the one-item FCR screening tool (revised Fear of Cancer Recurrence-1 [FCR-1r]) in a German cohort of urologic cancer patients. Validating such an ultra-brief measure may help address this clinically relevant gap and serve as a viable, clinically applicable alternative to lengthy questionnaires. Methods: Statistical analyses were conducted using R software. Criterion validity was assessed against the Concerns About Recurrence Questionnaire-4 (CARQ-4). Convergent validity was tested against the Fear of Progression Questionnaire \u2013 Short Form (FoP-Q-SF) and Generalised Anxiety Disorder-7 (GAD-7). Discriminant validity was tested against the Health Literacy Survey-European-Questionnaire 16 (HLS-EU-Q16). Validity was assessed using chi-square tests with phi coefficients, accuracy measures, negative and positive predictive values, sensitivity, specificity and odds ratios. Results: The final analysis sample consisted of 236 participants with complete data on all study measures. The FCR-1r demonstrated excellent criterion validity with respect to the CARQ-4 (\u03c72[1] = 101.97, p &lt; 0.001, \u03c6 = 0.66), with an overall accuracy of 84% (95% CI: 79\u201389%). Sensitivity was 84%, and specificity was 85%. The analysis of convergent validity revealed a moderate association with both the FoP-Q-SF (\u03c72[1] = 20.25, p &lt; 0.001, \u03c6 = 0.29; accuracy 62% [95% CI: 56\u201368%]) and the GAD-7 (\u03c72[1] = 11.82, p &lt; 0.001, \u03c6 = 0.22; accuracy 64% [95% CI: 58\u201370%]). The analysis of discriminant validity showed no significant association between the FCR-1r and health literacy (HLS-EU-Q16): \u03c72(1) = 3.44, p = 0.064, \u03c6 = 0.12. Conclusion: The German version of the FCR-1r demonstrates good psychometric properties, confirming its validity as a tool for assessing FCR in clinical practice.&lt;\/p&gt;<\/jats:p>","DOI":"10.1159\/ort\/aecag002","type":"journal-article","created":{"date-parts":[[2026,8,6]],"date-time":"2026-08-06T13:05:19Z","timestamp":1786021519000},"page":"1-1","source":"Crossref","is-referenced-by-count":0,"title":["Validity of the German Version of the FCR-1r Questionnaire in Patients with Urologic Cancer"],"prefix":"10.1159","author":[{"given":"Can","family":"D\u00fcmd\u00fcz","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sebastian","family":"Sage","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sofia","family":"Kugler","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"G\u00fcnter","family":"Niegisch","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christian","family":"Schulz-Quach","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ralf","family":"Sch\u00e4fer","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andr\u00e9","family":"Karger","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ulrike","family":"Dinger","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dominik","family":"Fugmann","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"127","published-online":{"date-parts":[[2026,8,3]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.3322\/caac.21834"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.1016\/S1470-2045(19)30456-5"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1158\/1055-9965.EPI-23-1006"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.1097\/CEJ.0000000000000594"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.1002\/pon.3998"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.1016\/S1470-2045(11)70002-X"},{"key":"ref7","doi-asserted-by":"publisher","DOI":"10.1093\/annonc\/mdp515"},{"key":"ref8","doi-asserted-by":"publisher","DOI":"10.1055\/s-0032-1309032"},{"key":"ref9","doi-asserted-by":"publisher","DOI":"10.1002\/pon.5188"},{"key":"ref10","doi-asserted-by":"publisher","DOI":"10.1002\/pon.6205"},{"key":"ref11","doi-asserted-by":"publisher","DOI":"10.1016\/j.cpr.2018.12.001"},{"key":"ref12","doi-asserted-by":"publisher","DOI":"10.1002\/pon.1437"},{"key":"ref13","doi-asserted-by":"publisher","DOI":"10.1002\/pon.3069"},{"key":"ref14","doi-asserted-by":"publisher","DOI":"10.1016\/j.ygyno.2012.10.014"},{"key":"ref15","doi-asserted-by":"publisher","DOI":"10.1007\/s00520-011-1371-x"},{"key":"ref16","doi-asserted-by":"publisher","DOI":"10.1007\/s11764-013-0272-z"},{"key":"ref17","doi-asserted-by":"publisher","DOI":"10.1200\/JCO.2009.22.5151"},{"key":"ref18","doi-asserted-by":"publisher","DOI":"10.1007\/s00520-009-0615-5"},{"key":"ref19","doi-asserted-by":"publisher","DOI":"10.1002\/pon.5350"},{"key":"ref20","doi-asserted-by":"publisher","DOI":"10.1002\/pon.2070"},{"key":"ref21","doi-asserted-by":"publisher","DOI":"10.1002\/pon.6139"},{"key":"ref22","doi-asserted-by":"publisher","DOI":"10.1007\/s11764-014-0383-1"},{"key":"ref23","doi-asserted-by":"publisher","DOI":"10.3390\/healthcare12040435"},{"key":"ref24","doi-asserted-by":"publisher","DOI":"10.13109\/zptm.2006.52.3.274"},{"key":"ref25","doi-asserted-by":"publisher","DOI":"10.1016\/j.jpsychores.2005.02.007"},{"key":"ref26","doi-asserted-by":"publisher","DOI":"10.1097\/MLR.0b013e318160d093"}],"container-title":["Oncology Research and Treatment"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/karger.com\/article-pdf\/doi\/10.1159\/ort\/aecag002","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,10,2]],"date-time":"2026-10-02T07:18:24Z","timestamp":1790925504000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/ort\/aecag002"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,8,3]]},"references-count":26,"URL":"https:\/\/doi.org\/10.1159\/ort\/aecag002","archive":["Portico"],"relation":{"is-supplemented-by":[{"id-type":"doi","id":"10.6084\/m9.figshare.33135779","asserted-by":"subject"}]},"ISSN":["2296-5270","2296-5262"],"issn-type":[{"value":"2296-5270","type":"print"},{"value":"2296-5262","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026,8,3]]}}}
