The focus on health-related quality of life (HRQOL) in medical research is becoming more and more intensive, with attention being paid to the patient's subjective feelings and assessment of one's health status. Smell disorders can significantly impact human life. The Questionnaire of Olfactory Disorders (QOD) is a self-monitoring questionnaire that provides subjective information about olfactory disorders.
This study aimed to check the reliability and validation of the Polish version of QOD (QOD-PL) for use in patients with olfactory impairment in Poland.
A total of 158 patients (76 females, mean age (Mage) 45.97 ±16.37 years), suffering from chronic rhinosinusitis (CRS), whose olfactory function was measured using the Sniffin' Sticks test (SST), were studied. All patients completed 3 validated questionnaires: Importance of Olfaction (IO), Sino-Nasal Outcome Test-22 (SNOT-22) and QOD-PL.
Internal consistency and test-retest reliability of the entire QOD-PL scale were good (Cronbach's α = 0.88). The convergent validity of the QOD-PL and its subscales correlated with IO and SNOT-22. The life quality statements in the QOD-PL (QOD-PL-LQ) score, its negative statements, and the mean score for VAS scales were significantly and positively correlated with all symptoms measured with SNOT-22 and none of the IO scales.
The QOD-PL is a reliable, valid and important tool for assessing HRQOL in patients with olfactory disorders. However, it is important to note that not all of its subscales can be considered and interpreted separately.
医学研究中越来越关注与健康相关的生活质量（HRQOL），关注患者对自身健康状况的主观感受和评估。嗅觉障碍会对人类生活产生重大影响。嗅觉障碍问卷（QOD）是一种自我监测问卷，提供了嗅觉障碍的主观信息。
本研究旨在检验波兰版嗅觉障碍问卷（QOD-PL）在波兰嗅觉障碍患者中的可靠性和有效性。
共纳入 158 名患者（76 名女性，平均年龄 45.97±16.37 岁），患有慢性鼻-鼻窦炎（CRS），其嗅觉功能使用嗅棒测试（SST）进行测量。所有患者均完成了 3 种已验证的问卷：嗅觉重要性问卷（IO）、鼻-鼻窦结局测试-22 项（SNOT-22）和 QOD-PL。
整个 QOD-PL 量表的内部一致性和重测信度良好（Cronbach's α=0.88）。QOD-PL 及其分量表的相关性具有良好的聚合效度，与 IO 和 SNOT-22 相关。QOD-PL 的生活质量陈述（QOD-PL-LQ）评分、其负面陈述以及 VAS 量表的平均评分与 SNOT-22 测量的所有症状显著正相关，而与 IO 量表均无相关性。
QOD-PL 是一种可靠、有效和重要的工具，可用于评估嗅觉障碍患者的 HRQOL。然而，需要注意的是，并非其所有分量表都可以单独考虑和解释。
