The Validated Hemophilia Regimen Treatment Adherence Scale-Prophylaxis (VERITAS-Pro) assesses adherence to prophylaxis treatment recommendations in hemophilia patients. This study aimed to adapt the VERITAS-Pro into Turkish and evaluate its reliability and validity. The research design used is a psychometric study. A convenience sample of 102 patients with hemophilia A or B was followed by the Aegean Adult Hemophilia and Thrombosis Center. The VERITAS-Pro was adapted to Turkish in six steps, including forward- and back-translation, committee review, and reliability and validity analysis. Based on the confirmatory factor analysis, modification indices suggested discrepancies amongst items, which were improved upon the removal of items 11 and 15. Findings from this alternative model are: χ2/df = 1.34; RMSEA = 0.05; SRMR = 0.09; and IFI = 0.92. The alternative model showed high adherence rates. Cronbach's alpha value for the Turkish version was found to be 0.83. The test-retest reliability of the Turkish scale ranged from 0.31 to 0.78. All items discriminated significantly between participants who were more adherent and those who were less adherent (t = 23.53; p<0.01). Translation of the VERITAS-Pro into local languages enables more accurate measurement of treatment adherence among people with hemophilia and facilitates cross-cultural comparison studies. According to the validity and reliability evidence obtained, the psychometric properties of the Turkish version of the VERITAS-Pro are suitable.
验证的血友病方案治疗依从性量表-预防（VERITAS-Pro）评估血友病患者预防治疗建议的依从性。本研究旨在将 VERITAS-Pro 改编为土耳其语，并评估其信度和效度。本研究采用心理测量学研究设计。对爱琴海成人血友病和血栓形成中心的 102 名血友病 A 或 B 患者进行了便利抽样。VERITAS-Pro 通过六个步骤被改编为土耳其语，包括正向和反向翻译、委员会审查以及信度和效度分析。基于验证性因素分析，修正指标表明项目之间存在差异，通过删除项目 11 和 15 得到了改进。该替代模型的结果为：χ2/df = 1.34；RMSEA = 0.05；SRMR = 0.09；IFI = 0.92。替代模型显示出较高的依从率。土耳其语版本的克朗巴赫 α 值为 0.83。土耳其语量表的重测信度范围为 0.31 至 0.78。所有项目在依从性较高和较低的参与者之间有显著差异（t = 23.53；p<0.01）。将 VERITAS-Pro 翻译成当地语言可以更准确地测量血友病患者的治疗依从性，并促进跨文化比较研究。根据获得的有效性和可靠性证据，VERITAS-Pro 土耳其语版本的心理测量学特性是合适的。
