一个有效的措施鼻窦炎的健康状况和生活质量是需要完整的评估治疗效果。本研究的目的是分析20项鼻窦预后测试（SNOT-20）的心理测量学和临床测量学效度，SNOT-20是一种针对鼻窦炎的疾病特异性、健康相关的生活质量测量方法。SNOT-20是31项鼻窦炎结局测量的修改，它包含20个鼻，鼻窦和一般项目。为了完成仪器，患者指出他们在每个区域受到影响的程度，并确定5个最重要的项目。分别有102、72和46名患者在初次访视时以及治疗开始后6个月和1年时完成了SNOT-20。克朗巴赫的α为0.9;重测分数高度相关（r = 0.9）。SNOT-20评分随病情加重而增加（P < 0.002），随病情好转而增加（P < 0.04）。被确定为重要的项目得分更高（P < 0.0001），并且显示出更大的变化得分（P < 0.0002）。SNOT-20是鼻窦炎患者的有效结局指标;它描述了健康负担，对临床变化敏感。
A valid measure of rhinosinusitis health status and quality of life Is required for the complete assessment of treatment effectiveness. The purpose of this study was to analyze the psychometric and clinimetric validity of the 20-Item Sino-Nasal Outcome Test (SNOT-20), a disease-specific, health-related quality-of-life measure for rhinosinusitis. The SNOT-20 is a modification of the 31-item Rhinosinusitis Outcome Measure, and it contains 20 nose, sinus, and general items. To complete the instrument, patients indicate how much they are affected in each area and identify the 5 most important items. The SNOT-20 was completed by 102, 72, and 46 patients at the initial visit and at 6 months and 1 year after treatment commencement, respectively. Cronbach's alpha was 0.9; test-retest scores were highly correlated (r = 0.9). Patients who were more affected had greater SNOT-20 scores (P < 0.002), and patients who had improved had greater change scores (P < 0.04). Items identified as important had greater scores (P < 0.0001) and showed greater change scores (P < 0.0002). The SNOT-20 is a valid outcome measure for patients with rhinosinusitis; it describes the health burden and is sensitive to clinical change.
