To provide additional validity data for the Asthma Control TestTM (ACT) using a different criterion measure, setting, and population.
Cross-sectional survey.
Questionnaires were completed at home by a random sample of 570 members of a large integrated healthcare organization who were 35 years or older with utilization suggestive of active asthma. The questionnaires included the ACT; another validated asthma control questionnaire (Asthma Therapy Assessment Questionnaire [ATAQ]), which was used as the criterion measure; a validated quality-of-life tool (Mini Asthma Quality of Life Questionnaire [Mini-AQLQ]); a validated symptom frequency scale (Asthma Outcomes Monitoring System); and information regarding demographics.
The ACT score was statistically significantly correlated with findings on the ATAQ (P = -0.73), Mini-AQLQ (P = 0.77), and symptom frequency scale (P = -0.69). The optimal ACT cutoff for well-controlled asthma (ATAQ level, 0) was confirmed to be 20 or higher (sensitivity, 78.1%; specificity, 83.8%), and the optimal ACT cutoff for poorly controlled asthma (ATAQ level, 3-4) was confirmed to be 15 or lower (sensitivity, 90.4%; specificity, 80.9%).
These data further support the validity of the ACT in the home setting among a random sample of patients with asthma.
使用不同的标准测量方法、环境和人群，为哮喘控制测试（ACT）提供更多有效性数据。
横断面调查。
对一家大型综合医疗保健机构中570名35岁及以上且有哮喘活动迹象的成员进行随机抽样，让他们在家中完成问卷调查。问卷包括ACT；另一份经过验证的哮喘控制问卷（哮喘治疗评估问卷[ATAQ]），用作标准测量；一份经过验证的生活质量工具（小型哮喘生活质量问卷[Mini - AQLQ]）；一份经过验证的症状频率量表（哮喘结果监测系统）；以及人口统计学信息。
ACT评分与ATAQ结果（P = -0.73）、Mini - AQLQ结果（P = 0.77）和症状频率量表结果（P = -0.69）在统计学上显著相关。哮喘控制良好（ATAQ水平为0）时ACT的最佳临界值被确认为20或更高（敏感性为78.1%；特异性为83.8%），哮喘控制不佳（ATAQ水平为3 - 4）时ACT的最佳临界值被确认为15或更低（敏感性为90.4%；特异性为80.9%）。
这些数据进一步支持了ACT在哮喘患者随机样本的家庭环境中的有效性。
