本研究的目的是校准一个条目库的计算机自适应测试（CAT）的哮喘对健康相关的生活质量（HRQOL）的影响，测试CAT版本的不同长度，进行初步的有效性测试，并评估条目库的可读性。哮喘影响调查（AIS）库项目，通过焦点小组，认知测试，临床和心理测量的审查管理的成人哮喘控制水平不同。自我报告哮喘的成人（N=1106）完成了一项互联网调查，包括88个AIS项目，哮喘控制测试（ACT）和其他HRQOL结局指标。数据进行了分析，使用经典和现代的心理测量方法，真实数据CAT模拟，和已知的群体有效性测试。测试了一个具有一般因素（哮喘影响）和几个组因素（认知功能、疲劳、心理健康、身体功能、角色功能、性功能、自我意识/耻辱、睡眠和社会功能）的双因素模型。一般因子上的载荷大于0.5，并且显著大于组因子载荷，拟合统计量是可接受的。大多数项目的项目功能和模型拟合是可以接受的。CAT模拟演示了管理和停止规则的几个选项。AIS区分了哮喘控制水平不同的受访者。新的50项AIS题库表现出良好的心理测量学特征，有效性的初步证据，并在中等阅读水平的可访问性。开发CAT项目库可以提高哮喘结果的精确、有效和全面监测，并可能促进以患者为中心的护理。
The purpose of this research was to calibrate an item bank for a computerized adaptive test (CAT) of asthma impact on health-related quality of life (HRQOL), test CAT versions of varying lengths, conduct preliminary validity testing, and evaluate item bank readability. Asthma Impact Survey (AIS) bank items that passed focus group, cognitive testing, and clinical and psychometric reviews were administered to adults with varied levels of asthma control. Adults self-reporting asthma (N=1106) completed an Internet survey including 88 AIS items, the Asthma Control Test (ACT), and other HRQOL outcome measures. Data were analyzed using classical and modern psychometric methods, real-data CAT simulations, and known groups validity testing. A bi-factor model with a general factor (asthma impact) and several group factors (cognitive function, fatigue, mental health, physical function, role function, sexual function, self-consciousness/stigma, sleep, and social function) was tested. Loadings on the general factor were above 0.5 and were substantially larger than group factor loadings, and fit statistics were acceptable. Item functioning for most items and fit to the model was acceptable. CAT simulations demonstrated several options for administration and stopping rules. AIS distinguished between respondents with differing levels of asthma control. The new 50-item AIS item bank demonstrated favorable psychometric characteristics, preliminary evidence of validity, and accessibility at moderate reading levels. Developing item banks for CAT can improve the precise, efficient, and comprehensive monitoring of asthma outcomes, and may facilitate patient-centered care.
