This study aimed to translate and culturally adapt the IBD-Disk into Turkish and evaluate its psychometric performance and association with clinical disease activity.\r\nMaterials and Methods: This prospective validation study was conducted between July 2025 and April 2026 at a tertiary referral center. The IBD-Disk was translated using a standardized forward\u2013backward methodology and pilot tested. Assessments were performed at baseline, after 2 weeks in a clinically stable subgroup to evaluate test\u2013retest reliability, and at 6-month follow-up. Disease activity was assessed using the Harvey\u2013Bradshaw Index for Crohn\u2019s disease (CD), partial Mayo score for ulcerative colitis (UC), and the Physician Global Assessment (PGA).\r\nResults: A total of 202 patients were included, comprising 114 with CD and 88 with UC; 136 patients had complete longitudinal data. The Turkish IBD-Disk demonstrated high internal consistency (Cronbach\u2019s \u03b1 = 0.884) and moderate test\u2013retest reliability (intraclass correlation coefficient = 0.68; 95% CI, 0.16-0.90). IBD-Disk scores were moderately correlated with disease activity indices in patients with CD and UC (\u03c1 = 0.525 and \u03c1 = 0.503, respectively; both P &lt; .001) and differed significantly across PGA categories (P &lt; .001). The instrument demonstrated moderate accuracy for detecting active disease (area under the curve = 0.72; 95% CI, 0.65-0.79), with a preliminary receiver operating characteristic\u2013derived cutoff of \u226527.5 (sensitivity 76.1%, specificity 60.5%). Scores decreased significantly among patients with clinical improvement at follow-up (P &lt; .001).\r\nConclusion: The Turkish version of the IBD-Disk demonstrated acceptable validity and reliability for assessing patient-perceived disease burden in patients with IBD and demonstrated responsiveness to clinical improvement.\r\nCite this article as: Tolu T, Kaldirim Armutcuoglu Y, Yilmaz Yildirim T, et al.
