title: Validation of the Turkish version of "Test for Respiratory and Asthma Control in Kids (TRACK)" questionnaire.
abstract: BACKGROUND
  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 and responsiveness of the Turkish version of the TRACK.
  
  
  METHODS
  A total of 268 children (69.8% boys) were included in the study. Caregivers responded to three individual TRACK questionnaires, at each clinical visit (baseline, 1st month, and 3rd month). At each visit, physicians determined the control level and the treatment strategy based on the GINA guideline recommendations.
  
  
  RESULTS
  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 alpha). 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 in stable patients was 0.90. The optimal cut-off scores according to the Youden index were 80 and 60 points for uncontrolled and very poorly controlled children, respectively.
  
  
  CONCLUSIONS
  The Turkish version of the TRACK is an accurate and reliable tool for evaluating asthma control status among preschool Turkish children. Its widespread use may help physicians correctly assess control levels among children and may improve the quality of life for both patients and their caregivers.
