The present study was conducted with the aim to translate, adapt, and validate the 8-item Overactive Bladder Questionnaire (OAB-V8) in Croatia.
This study included a total of 58 female patients with OAB and 66 healthy women. The translation to Croatian followed standardized procedure. All eligible participants completed OAB-V8 at inclusion and 2 weeks after to assess test-retest reliability. Cronbach α coefficient was calculated to assess internal consistency.
Our study demonstrated high internal consistency for all items at both visits (Cronbach α between 0.799 and 0.847), with stable internal consistency reliability across items during the 2-week period. However, the exception is the item "waking up at night to urinate," which significantly changed during the 2-week period. Intraclass correlation for OAB-V8 items ranged from 0.810 to 1.0, with Spearman correlations greater than 0.9 for all items (P < 0.01). There were strong significant correlations between frequency of urination during daytime and uncomfortable and sudden urge to urinate, and between nocturia and waking up at night. Discriminative validity showed statistically significant score differences between patients and the control group.
The Croatian version of the OAB-V8 was successfully translated, adapted, and validated so the questionnaire is now ready for use as a reliable tool for initial screening and assessing patients with OAB in everyday Croatian clinical practice.
本研究旨在将 8 项膀胱过度活动症问卷（OAB-V8）翻译、改编并验证为克罗地亚语。
本研究共纳入 58 例 OAB 女性患者和 66 例健康女性。翻译遵循标准化程序。所有符合条件的参与者在纳入时和 2 周后完成 OAB-V8，以评估测试-重测信度。计算 Cronbach α 系数以评估内部一致性。
我们的研究显示，所有项目在两次就诊时的内部一致性均较高（Cronbach α 在 0.799 至 0.847 之间），在 2 周期间项目的内部一致性可靠性稳定。然而，例外是“夜间醒来排尿”这一项，其在 2 周期间发生显著变化。OAB-V8 项目的组内相关系数范围为 0.810 至 1.0，所有项目的 Spearman 相关系数均大于 0.9（P<0.01）。日间排尿频率与不适和突然尿急之间，以及夜尿与夜间醒来之间存在强烈的显著相关性。判别有效性显示患者和对照组之间的评分差异具有统计学意义。
OAB-V8 的克罗地亚语版本已成功翻译、改编和验证，现在可作为在日常克罗地亚临床实践中用于初始筛查和评估 OAB 患者的可靠工具。
