The study aimed to translate the Urethral Stricture Surgery Patient Reported Outcome Measures (USS-PROM) questionnaire in Dutch. To validate this translated questionnaire, the study evaluates its psychometric properties in a different population, a different environment, and a different health care system. Questions about urinary incontinence and sexual functioning were added.
Between December 2014 and January 2017, Dutch-speaking adult men scheduled for urethroplasty at Ghent University Hospital were prospectively enrolled in this study. Patients completed the USS-PROM before surgery, 3-6 months after surgery, and 1 year after surgery. Psychometric criteria included content validity, criterion validity, internal consistency, reproducibility, responsiveness, and floor and ceiling effects. (EC/2014/0438).
A total of 100 patients were included, 39 patients completed both the preoperative and the postoperative questionnaire, and 30 patients completed the USS-PROM twice within a short period of time in order to evaluate test-retest reliability. Pearson correlation coefficients showed no statistical significant correlation between lower urinary tract symptoms (LUTS) scores and maximum flow rates. Cronbach's α was 0.81 and 0.89, respectively, for the LUTS score and the summative Male Sexual Health Questionnaire Ejaculatory Dysfunction short form (MSHQ-EjD short form) score. The intraclass correlation coefficients ranged from 0.72 to 0.94. Significant changes were observed in all items except the MSHQ-EjD short form scores. All values exceeded the predefined thresholds.
The Dutch version of the USS-PROM has adequate psychometric properties and is a valid instrument to assess patient-reported outcome measures in men undergoing urethroplasty.
本研究旨在将尿道狭窄手术患者报告结局量表（USS - PROM）问卷翻译成荷兰语。为验证这份翻译后的问卷，本研究在不同人群、不同环境和不同医疗保健系统中评估其心理测量特性。增加了关于尿失禁和性功能的问题。
2014年12月至2017年1月期间，在根特大学医院计划接受尿道成形术的荷兰语成年男性被前瞻性纳入本研究。患者在手术前、手术后3 - 6个月以及手术后1年完成USS - PROM。心理测量标准包括内容效度、标准效度、内部一致性、可重复性、反应性以及地板效应和天花板效应。（EC/2014/0438）
共纳入100例患者，39例患者完成了术前和术后问卷，30例患者在短时间内完成了两次USS - PROM以评估重测信度。Pearson相关系数显示下尿路症状（LUTS）评分与最大尿流率之间无统计学显著相关性。LUTS评分和男性性健康问卷射精功能障碍简表（MSHQ - EjD简表）总分的Cronbach's α分别为0.81和0.89。组内相关系数范围为0.72至0.94。除MSHQ - EjD简表评分外，所有项目均观察到显著变化。所有值均超过预先设定的阈值。
USS - PROM荷兰语版本具有足够的心理测量特性，是评估接受尿道成形术男性患者报告结局指标的有效工具。
