The limited existing asthma control questionnaires that are available for children 5 years of age or younger in China mostly assess only the impairment domain of asthma control. Here, the English version of the Test for Respiratory and Asthma Control in Kids (TRACK) was translated into Chinese and validated for its application in asthma control in preschool children.
Prospective validation study.
A total of 321 Chinese preschool children suffering from asthma completed the study from December 2017 to February 2018.
The TRACK translation into Chinese employed the translation and back translation technique. The caregivers of the preschool children with asthma symptoms completed TRACK during two clinical visits over 4-6 weeks. Moreover, the physicians completed a Global Initiative for Asthma (GINA)-based asthma control survey at both visits. The utility of TRACK for assessing the change in asthma control status and its reliability and discriminant validity were evaluated.
The Chinese version of TRACK showed internal consistency reliability values of 0.63 and 0.71 at each visit, respectively (Cronbach's α). The test-retest reliability was 0.62 for individuals whose GINA-based assessment results were the same at both visits (n=206). The TRACK scores for the children in the various asthma control categories were significantly different (p<0.001). Children recommended for increased treatment by the physicians had lower TRACK scores than those recommended for no change in treatment or decreased treatment (p<0.001).
The study verifies the validity and reliability of the Chinese version of TRACK. Changes in the TRACK scores effectively reflected the level of asthma control in preschool children and guided further treatment strategies.

在中国，现有的适用于 5 岁及以下儿童的有限哮喘控制问卷大多仅评估哮喘控制的损害领域。在此，将英文版的儿童呼吸和哮喘控制测试（TRACK）翻译成中文，并对其在学龄前儿童哮喘控制中的应用进行验证。
前瞻性验证研究。
共有 321 名患有哮喘的中国学龄前儿童参加了这项研究，研究时间为 2017 年 12 月至 2018 年 2 月。
TRACK 中文翻译采用了翻译和回译技术。在 4-6 周的两次临床就诊期间，哮喘症状的学龄前儿童的照顾者完成了 TRACK。此外，医生在两次就诊时均完成了基于全球哮喘倡议（GINA）的哮喘控制调查。评估了 TRACK 评估哮喘控制状况变化的能力及其可靠性和判别有效性。
中文版 TRACK 在每次就诊时的内部一致性可靠性值分别为 0.63 和 0.71（Cronbach's α）。两次就诊时 GINA 评估结果相同的个体的测试-重测可靠性为 0.62（n=206）。在不同哮喘控制类别的儿童中，TRACK 评分存在显著差异（p<0.001）。医生建议增加治疗的儿童的 TRACK 评分低于建议维持治疗或减少治疗的儿童（p<0.001）。
本研究验证了中文版 TRACK 的有效性和可靠性。TRACK 评分的变化有效反映了学龄前儿童哮喘控制水平，并指导了进一步的治疗策略。
