Abstract

Background: Chronic rhinosinusitis (CRS) is one of common health conditions that affects patients' health-related quality of life. Our purpose is to assess the reliability and validity of Thai-version of Sino-Nasal Outcome Test 22 in chronic rhinosinusitis.

Methods: Permission for translation of SNOT-22 from English language to Thai language was obtained from the developer. The translation process was done based on the international standard of translation method. A total of 80 subjects were recruited into the study and divided into two groups comprising of 50 patients with chronic rhinosinusitis and 30 healthy volunteers. Cronbach's α and Intraclass correlation coefficient were evaluated for its reliability. Validity test was evaluated against VAS score, SF-36 (Thai version) questionnaire and CT scan (based on Lund-Mackay score). Responsiveness was assessed between pre-operative and post-operative scores in 34 patients.

Results: The Thai version of SNOT-22 showed good reliability according to high value of Cronbach's α coefficient (r = 0.929) and intraclass correlation coefficient (r = 0.935). It also showed good validity by its ability to differential the patients with chronic rhinosinusitis from normal (p < 0.001), and different severity of symptoms (p < 0.05). In addition, the SNOT-22 Thai version also showed good responsiveness when compared between pre-operative and post-operative scores (p < 0.001) and also well-performed in effect size calculation (1.37).

Conclusion: We demonstrated that Thai -version of SNOT-22 has good reliability and validity, suitable for evaluation of chronic rhinosinusitis symptoms together with severity of the disease and response to treatment.

Trial registration: Thai clinical trials registry TCTR20170320003. Date of registration 20/03/2017 (retrospectively registered).

慢性鼻窦炎中鼻结局检验22(泰国版)的信度和效度研究。

背景:慢性鼻窦炎(CRS)是影响患者健康相关生活质量的常见疾病之一。我们的目的是评估泰国版中国鼻结局测试22在慢性鼻窦炎中的信度和效度。方法:获得开发人员的许可，将SNOT-22从英语翻译成泰语。翻译过程是根据国际标准的翻译方法完成的。共有80名受试者被招募到这项研究中，并被分为两组，其中50名慢性鼻窦炎患者和30名健康志愿者。对其信度进行Cronbach’s α和class内相关系数评估。对照VAS评分、SF-36(泰国版)问卷和CT扫描(基于Lund-Mackay评分)进行效度检验。对34例患者进行术前和术后反应性评分。结果:泰国版SNOT-22量表具有较高的Cronbach′s α系数(r = 0.929)和类内相关系数(r = 0.935)，具有较好的信度。结论:泰国版SNOT-22量表具有良好的信度和效度，适用于慢性鼻窦炎症状、病情严重程度和治疗反应的评价。试验注册:泰国临床试验注册中心TCTR20170320003。注册日期20/03/2017(追溯注册)。
