目的：为了评估可靠性，反应性，对患者的重要性，和收敛效度的威斯康星州上呼吸道症状调查（WURSS-44），并制定一个简短的形式WURSS.Study设计和设置：以社区为基础的参与者招募感冒。从出现首次症状后48小时内到感冒结束后2天进行前瞻性监测。WURSS-44包括I个总体疾病严重程度项目、32个基于疾病的项目、10个功能性生活质量项目和I个评估总体变化的项目。SF-36，SF-8和杰克逊感冒量表被用作外部comparators.Results：参与者包括104名女性和45名男性，年龄在18至80岁，自我报告的1,681人的疾病。因子分析得到10个维度，信度系数在0.62 ~ 0.93之间。将每日WURSS-44与杰克逊和SF-8进行比较，得出的Pearson相关系数分别为0.73至0.93和-0.60至-0.84。对患者的重要性和反应性评估产生了一个简短的版本，WURSS-21。SF-8、杰克逊、WURSS-44和WURSS-21的Guyatt反应性指数分别为0.54、0.61、0.71和0.80，表明双组试验需要74名参与者参与WURSS-21、92名参与者参与WURSS-44、124名参与杰克逊量表和156名参与SF-8。WURSS-44的结构效度得到了可靠性、反应性、对患者的重要性和收敛性等指标的支持。一个更短的版本，WURSS-21，可能更灵敏。(c)2005年爱思唯尔公司All rights reserved.
Objective: To assess reliability, responsiveness, importance to patients, and convergent validity for the Wisconsin Upper Respiratory Symptom Survey (WURSS-44) and to develop a short-form WURSS.Study Design and Setting: Community-based recruitment of participants with colds. Prospective monitoring from within 48 hours of first symptom until 2 days after end of cold. The WURSS-44 includes I global illness severity item, 32 symptom-based items, 10 functional quality-of-life items, and I item assessing global change. The SF-36, SF-8, and the Jackson cold scale were used as external comparators.Results: Participants included 104 women and 45 men, aged 18 to 80 years, self-reporting on 1,681 person-days of illness. Factor analysis suggested 10 dimensions, with reliability coefficients from 0.62 to 0.93. Comparing daily WURSS-44 to Jackson and SF-8 yielded Pearson correlation coefficients from 0.73 to 0.93, and from -0.60 to -0.84, respectively. Importance to patients and responsiveness assessment yielded a short version, the WURSS-21. Guyatt's responsiveness index was 0.54 for the SF-8, 0.61 for the Jackson, 0.71 for the WURSS-44, and 0.80 for the WURSS-21, suggesting that a two-armed trial would require 74 participants for the WURSS-21, 92 for the WURSS-44, 124 for the Jackson scale, and 156 for the SF-8.Conclusions: The construct validity of WURSS-44 is supported by measures of reliability, responsiveness, importance to patients, and convergence. A shorter version, the WURSS-21, may be even more responsive. (c) 2005 Elsevier Inc. All rights reserved.
