This study developed a short form of the traditional Chinese version of the Weinstein Noise Sensitivity Scale (WNSS) through optimal test assembly (OTA). A total of 1069 Chinese adults (64.8% female) completed the territory-wide cross-sectional study. We first removed Items 12 and 5 which had negative factor loading and gender-related differential item functioning (DIF), respectively. The optimal length was then determined as the minimal one that reasonably resembled the reliability and validity of the scale without DIF items. OTA identified an 8-item WNSS (WNSS-8) which retained 67.2% of the test information of the original 21-item scale and had a Cronbach's alpha of 0.83. It also showed significant correlations of 0.272 and -0.115 with the neuroticism and extraversion scales of Chinese NEO-Five Factor Inventory, respectively. Adequate model fit of the WNSS-8 was demonstrated by the confirmatory factor analysis. The Chinese WNSS-8 can be used to assess noise sensitivity without compromising reliability and validity.
本研究通过最优测验组合（OTA）开发了 Weinstein 噪声敏感性量表（WNSS）的简体中文版短式量表。共有 1069 名中国成年人（64.8%为女性）完成了这项全港性的横断面研究。我们首先删除了因子负荷为负和具有性别相关差异项目功能（DIF）的第 12 项和第 5 项。然后，最优长度确定为没有 DIF 项目的情况下，合理地类似于量表可靠性和有效性的最短长度。OTA 确定了一个 8 项的 WNSS（WNSS-8），保留了原始 21 项量表的 67.2%的测试信息，克朗巴赫 α系数为 0.83。它还显示与中国 NEO-五因素人格量表的神经质和外向性量表分别有 0.272 和 -0.115 的显著相关性。验证性因素分析证明了 WNSS-8 的适当模型拟合度。WNSS-8 可用于评估噪声敏感性，而不会影响可靠性和有效性。
