Persistent symptoms affect physical functioning, psychological well-being, social interactions, and intimate relationships. Therefore, validated disease-specific instruments are essential for accurate QoL assessment in different populations. Objective: The aim of this study was to validate the Serbian version of the Hidradenitis Suppurativa Quality of Life Questionnaire (HSQoL-24). Methods: The validation process followed established methodological guidelines for psychometric evaluation. The Serbian HSQoL-24 version demonstrated satisfactory psychometric properties. Internal consistency was excellent, with a Cronbach \u03b1 of 0.907. Test\u2013retest reliability was confirmed using an intraclass correlation coefficient (ICC) of 0.986 for the total score, demonstrating satisfactory reproducibility over time. A strong positive correlation was observed between the HSQoL-24 and Dermatology Life Quality Index (DLQI) total scores (Spearman\u2019s \u03c1 = 0.806, p &lt; 0.001), confirming good convergent validity, particularly in domains related to symptoms and feelings, occupational or educational functioning, and interpersonal relationships. Moreover, total HSQoL-24 scores increased significantly with disease severity, indicating the questionnaire\u2019s ability to discriminate between patients with different Hurley stages and confirming its discriminant validity. Conclusions: The Serbian version of the HSQoL-24 questionnaire exhibits appropriate internal consistency, test\u2013retest reliability, and convergent and discriminant validity. These results support its use as a reliable and valid disease-specific instrument for assessing QoL in Serbian-speaking patients with HS in both clinical practice and research settings.<\/jats:p>","DOI":"10.3390\/jcm15062436","type":"journal-article","created":{"date-parts":[[2026,3,23]],"date-time":"2026-03-23T09:48:42Z","timestamp":1774259322000},"page":"2436","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Reliability and Validity of the Serbian Version of the Hidradenitis Suppurativa Quality of Life Questionnaire (HSQoL-24)"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7885-467X","authenticated-orcid":false,"given":"Milana","family":"Marinkovic","sequence":"first","affiliation":[{"name":"Clinic for Burns, Plastic and Reconstructive Surgery, University Clinical Center of Serbia, 11000 Belgrade, Serbia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4545-4335","authenticated-orcid":false,"given":"Milan","family":"Stoji\u010di\u0107","sequence":"additional","affiliation":[{"name":"Clinic for Burns, Plastic and Reconstructive Surgery, University Clinical Center of Serbia, 11000 Belgrade, Serbia"},{"name":"Faculty of Medicine, University of Belgrade, 11000 Belgrade, Serbia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marko S.","family":"Jovi\u0107","sequence":"additional","affiliation":[{"name":"Clinic for Burns, Plastic and Reconstructive Surgery, University Clinical Center of Serbia, 11000 Belgrade, Serbia"},{"name":"Faculty of Medicine, University of Belgrade, 11000 Belgrade, Serbia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8365-4840","authenticated-orcid":false,"given":"Jelena","family":"Rakocevic","sequence":"additional","affiliation":[{"name":"Faculty of Medicine, University of Belgrade, 11000 Belgrade, Serbia"},{"name":"Institute of Histology and Embryology \u201cAleksandar \u0110.
