Okul Öncesi Çağı Astımlı "Türk Çocuklarında Çocuklar Için Solunum ve Astım Kontrol Testi (ÇİSAKT)'nin" Geçerlilik, Güvenilirlik ve Değişime Duyarlılığı

Abstract

Test for Respiratory and Asthma Control in Kids (TRACK)? questionnaire is the first to measure both the risk and impairment domains of the current guidelines in preschool children. We aimed to measure the reliability, validity, responsiveness, and minimally important difference of the Turkish version of the TRACK questionnaire. A total of 268 children with a mean (±standard deviation) age 2.44 (±1.08) years were included in the study. Caregivers filled in three TRACK questionnaires at enrollment, 1st month, and 3rd month. At each visit, physicians determined the control level and the treatment step based on the GINA guideline recommendations. The internal consistency reliability of the Turkish version of the TRACK questionnaire was found to be 0.74, 0.74, and 0.76 at each of the three visits, respectively (reliability statistics, Cronbach?s ?). There was a significant difference between the mean TRACK scores of the patients in different asthma control status categories (p<0.001). The test-retest reliability was found 0.90. The optimal cut-off scores, according to the Youden index, for ?controlled? and ?poorly controlled? asthma, were 80 and 60 points, respectively. Responsiveness analyze revealed that both at the 2nd and 3rd visits, the mean TRACK score changes were significantly different between the groups (both p<0.001). TRACK scores increased in parallel with improved physician disease control ratings. The Turkish version of the TRACK is an accurate and reliable tool for assessing asthma control status among preschool Turkish children. Its widespread use may help physicians correctly assess control levels among children.
