The Wisconsin Upper Respiratory Symptom Survey (WURSS) is a self-administered questionnaire developed in the United States to evaluate the severity of the common cold and its reliability has been validated. We developed a Korean language version of this questionnaire by using a sequential forward and backward translation approach. The purpose of this study was to validate the Korean version of the Wisconsin Upper Respiratory Symptom Survey (WURSS-K) in Korean patients with common cold.
This multicenter prospective study enrolled 107 participants who were diagnosed with common cold and consented to participate in the study. The WURSS-K includes 1 global illness severity item, 32 symptom-based items, 10 functional quality-of-life (QOL) items, and 1 item assessing global change. The SF-8 was used as an external comparator.
The participants were 54 women and 53 men aged 18 to 42 years. The WURSS-K showed good reliability in 10 domains, with Cronbach's alphas ranging from 0.67 to 0.96 (mean: 0.84). Comparison of the reliability coefficients of the WURSS-K and WURSS yielded a Pearson correlation coefficient of 0.71 (P = 0.02). Validity of the WURSS-K was evaluated by comparing it with the SF-8, which yielded a Pearson correlation coefficient of -0.267 (P < 0.001). The Guyatt's responsiveness index of the WURSS-K ranged from 0.13 to 0.46, and the correlation coefficient with the WURSS was 0.534 (P < 0.001), indicating that there was close correlation between the WURSS-K and WURSS.
The WURSS-K is a reliable, valid, and responsive disease-specific questionnaire for assessing symptoms and QOL in Korean patients with common cold.
威斯康星州上呼吸道症状调查 (WURSS) 是一种在美国开发的自我管理问卷，用于评估普通感冒的严重程度，其可靠性已得到验证。我们通过使用顺序正向和反向翻译方法开发了该问卷的韩语版本。本研究的目的是验证韩国版威斯康星州上呼吸道症状调查 (WURSS-K) 在韩国普通感冒患者中的有效性。
这项多中心前瞻性研究纳入了 107 名被诊断为普通感冒并同意参与研究的患者。WURSS-K 包括 1 个整体疾病严重程度项目、32 个基于症状的项目、10 个功能生活质量 (QOL) 项目和 1 个整体变化评估项目。SF-8 用作外部比较器。
参与者为 54 名女性和 53 名年龄在 18 至 42 岁之间的男性。WURSS-K 在 10 个领域具有良好的可靠性，Cronbach's α 值范围为 0.67 至 0.96（平均值：0.84）。WURSS-K 和 WURSS 的可靠性系数比较得出 Pearson 相关系数为 0.71（P = 0.02）。通过与 SF-8 比较评估 WURSS-K 的有效性，得出 Pearson 相关系数为-0.267（P < 0.001）。WURSS-K 的 Guyatt 反应性指数范围为 0.13 至 0.46，与 WURSS 的相关系数为 0.534（P < 0.001），表明 WURSS-K 与 WURSS 之间存在密切相关性。
WURSS-K 是一种可靠、有效且敏感的疾病特异性问卷，可用于评估韩国普通感冒患者的症状和 QOL。
