Abstract

Background: The Asthma Control Test (ACT) has been widely used for the assessment of asthma control. However, it has never been validated in adult Thai asthmatic patients.

Objective: To determine the validity and reliability of the Thai version of the ACT in adult Thai asthmatic patients.

Methods: Any correlation between ACT and level of asthma controlled was determined using the Spearman's rank correlation coefficient. The ACT was carried out at 2 visits to a physician (4-12 weeks apart) to ascertain the level of reliability. Discriminant validity was determined using an area under receiver operating characteristic curve (AuROC) to identify the optimum cut-off point of the levels of control.

Results: Seventy-one asthmatic adult patients, 40 (56.3%) female with a mean age of 54.2 ± 14.7 years were enrolled. The Thai version of ACT showed an acceptable internal consistency reliability with a Cronbach's alpha = 0.75. Test-retest reliability was 0.82. There was a significant correlation between the ACT scores and GINA symptom control tool (r = 0.87, p < 0.001). An ACT ≤ 22 was used to screen "not well-controlled" asthma with a sensitivity of 96.4% and specificity of 93.0% and an ACT score ≤ 19 was used to screen "uncontrolled" asthma.

Conclusions: The Thai version of ACT is valid and a reliable tool for use in adult Thai asthmatic patients. However, the cut off points of ACT for levels of control should be changed to 22 and 19 for differentiation between well vs. partly controlled and partly vs. uncontrolled asthma, respectively.

泰语版哮喘控制测试的有效性和可靠性。

背景：哮喘控制测试（ACT哮喘控制测试（ACT）已被广泛用于评估哮喘控制情况。然而，该测试从未在泰国成年哮喘患者中进行过验证：目的：确定泰文版 ACT 在泰国成年哮喘患者中的有效性和可靠性：采用斯皮尔曼等级相关系数确定 ACT 与哮喘控制水平之间的相关性。为了确定 ACT 的可靠性，在医生的两次就诊中（间隔 4-12 周）进行了 ACT 测验。使用接收者操作特征曲线下面积（AuROC）确定判别效度，以确定控制水平的最佳临界点：71名成年哮喘患者中有40名（56.3%）女性，平均年龄为（54.2 ± 14.7）岁。泰语版 ACT 的内部一致性信度为 Cronbach's alpha = 0.75，可以接受。测试-再测可靠性为 0.82。ACT 分数与 GINA 症状控制工具之间存在明显的相关性（r = 0.87，p < 0.001）。ACT得分≤22分可用于筛查 "未得到良好控制 "的哮喘，灵敏度为96.4%，特异度为93.0%；ACT得分≤19分可用于筛查 "未得到控制 "的哮喘：泰语版 ACT 是用于泰国成年哮喘患者的有效、可靠的工具。结论：泰语版 ACT 是用于泰国成年哮喘患者的有效、可靠的工具，但应将 ACT 控制水平的临界点分别改为 22 分和 19 分，以区分哮喘控制良好与部分控制、部分控制与未控制。
