The Short Inflammatory Bowel Disease Questionnaire (SIBDQ) is a widely used instrument to assess Health-related Quality of Life (HRQoL) among inflammatory bowel disease (IBD) patients. Our aim was to translate and adapt the SIBDQ so that it could be adequately used in Portugal.
This is a prospective design cohort study undertaken at a tertiary hospital. This study took place simultaneously with the first part of the SexIDI study, a study aiming to assess the impact of IBD on patients' sexual QoL. The original SIBDQ was translated by two independent translators and adapted by an IBD expert panel following the opinions of a convenient sample of 5 IBD patients. Afterwards, IBD patients from the outpatient clinic were consecutively invited to fill the Portuguese version of the questionnaire (SIBDQ-PT) at three different timepoints (0, 2, 4 weeks). Ninety-two patients completed the SIBDQ-PT at baseline, whereas 33 did so after 2 and 4 weeks (approximately). Statistical analysis was performed using SPSS version 25, and the following aspects were analysed: reliability (through internal consistency, test-retest and intraclass correlation), validity (through exploratory factor analysis [EFA], and Pearson correlation coefficient for linear correlations), score distribution, and responsiveness analysis (through t-student tests).
Overall, SIBDQ-PT was shown to have a high internal consistency (Cronbach's α = 0.80) and a high test-retest reliability (0.80 [CI 0.74-0.86] and 0.69 [CI 0.50-0.82]). EFA detected four dimensions-bowel, social, emotional and systemic. As expected, an overall SIBDQ-PT score was positively correlated with sexual satisfaction (r = 0.27; p < 0.05) and negatively correlated with depression (r = - 0.63; p < 0.01). Moreover, SIBDQ-PT was found to have an adequate score distribution, and to be responsive, as there was a significant subscore change for patients who reported an "overall worsening in general well-being" (0.93 ± 0.13 decrease; p < 0.01).
The Portuguese version of the SIBDQ hereby presented is a reliable, valid and responsive instrument that can be used to measure HRQoL among Portuguese IBD patients.
短炎症性肠病问卷（SIBDQ）是一种广泛用于评估炎症性肠病（IBD）患者健康相关生活质量（HRQoL）的工具。我们的目的是翻译和改编 SIBDQ，以便在葡萄牙得到充分应用。
这是一项在一家三级医院进行的前瞻性设计队列研究。该研究与第一部分 SexIDI 研究同时进行，该研究旨在评估 IBD 对患者性生活质量的影响。原始的 SIBDQ 由两名独立的翻译翻译，并由 IBD 专家小组根据 5 名 IBD 患者的方便样本的意见进行改编。随后，门诊的 IBD 患者连续在三个不同时间点（0、2、4 周）填写葡萄牙语版问卷（SIBDQ-PT）。92 名患者在基线时完成了 SIBDQ-PT，而 33 名患者在 2 周和 4 周后完成了（大约）。使用 SPSS 版本 25 进行统计分析，分析了以下方面：可靠性（通过内部一致性、测试-重测和组内相关系数）、有效性（通过探索性因子分析[EFA]和 Pearson 相关系数进行线性相关性）、评分分布和响应性分析（通过 t 检验）。
总体而言，SIBDQ-PT 表现出较高的内部一致性（Cronbach's α=0.80）和较高的测试-重测可靠性（0.80[CI 0.74-0.86]和 0.69[CI 0.50-0.82]）。EFA 检测到四个维度-肠道、社会、情绪和系统。正如预期的那样，SIBDQ-PT 的总分与性满意度呈正相关（r=0.27；p<0.05），与抑郁呈负相关（r=-0.63；p<0.01）。此外，SIBDQ-PT 的评分分布适当，且具有响应性，因为报告“整体健康状况总体恶化”的患者的亚评分有显著变化（0.93±0.13 减少；p<0.01）。
本文提出的葡萄牙语版 SIBDQ 是一种可靠、有效且具有响应性的工具，可用于衡量葡萄牙 IBD 患者的 HRQoL。
