TRACK (Test for Respiratory and Asthma Control in Kids) questionnaire is an instrument developed and validated in English to evaluate the control of respiratory symptoms in children under 5 years of age.
To validate the Portuguese version of the TRACK questionnaire.
The validation was done in an observational, prospective and multicenter evaluation (six centers in Brazil) in children with recurrent respiratory symptoms. Children were classified according to symptoms, GINA criteria and medical evaluation. Parents and doctors rated child respiratory symptom control in the last month (VAS). Approval from the Institutional Review Board was obtained in each centre, and written informed consent was obtained from parents.
Data from 299 children were obtained at baseline, and 195 at follow-up. The median score of the TRACK questionnaire was 65 and Cronbach's α was 0.70. TRACK scores showed significant correlation with the medical and family opinions about symptom control (r: 0.74 and r: 0.61). TRACK scores were significantly lower in children who had used systemic steroids (median [IQR]: 45 [30-65] vs 75 [55-80]; < 0.001) and had an emergency visit in the last month (45 [35-60] vs 70 [55-80]; < 0.001). TRACK scores were also significantly different when children were separated by the medical opinion, GINA criteria and symptoms. Comparison of different respiratory symptom control cut-off points showed that the cut-off of 80 points had the highest area under ROC curve (0.800).
We have demonstrated that the Portuguese version of the TRACK questionnaire has satisfactory reliability (internal consistency), adequate criterion validity (compared against GINA levels of control) and constructive validity (compared against respiratory symptoms and medical opinion), showing that it can be a useful tool to discriminate among children with different levels of respiratory symptom control.

TRACK（儿童呼吸与哮喘控制测试）问卷是一种以英文开发并验证的工具，用于评估5岁以下儿童的呼吸道症状控制情况。
验证TRACK问卷的葡萄牙语版本。
在一项针对反复出现呼吸道症状儿童的观察性、前瞻性多中心评估（巴西的六个中心）中进行验证。根据症状、全球哮喘防治创议（GINA）标准和医学评估对儿童进行分类。家长和医生对儿童过去一个月的呼吸道症状控制情况进行评分（视觉模拟评分法）。每个中心均获得了机构审查委员会的批准，并获得了家长的书面知情同意。
基线时获得了299名儿童的数据，随访时获得了195名儿童的数据。TRACK问卷的中位数分数为65，克朗巴哈系数α为0.70。TRACK分数与关于症状控制的医学和家庭意见显著相关（r分别为0.74和0.61）。使用过全身用类固醇的儿童（中位数[四分位间距]：45[30 - 65]对75[55 - 80]；P < 0.001）以及过去一个月内有过急诊就诊的儿童（45[35 - 60]对70[55 - 80]；P < 0.001）的TRACK分数显著更低。当根据医学意见、GINA标准和症状对儿童进行分类时，TRACK分数也存在显著差异。不同呼吸道症状控制切点的比较表明，80分的切点在ROC曲线下面积最大（0.800）。
我们已证明，TRACK问卷的葡萄牙语版本具有令人满意的信度（内部一致性）、足够的效标效度（与GINA控制水平相比）和结构效度（与呼吸道症状和医学意见相比），表明它可作为区分不同呼吸道症状控制水平儿童的有用工具。
