The validity and reliability of the ADL-Glittre test for children

ABSTRACT

Objective: The ADL-Glittre was created to assess more comprehensively the essential activities of daily living in adults with chronic obstructive pulmonary disease. The aim of this study was to validate the ADL-Glittre test adapted for children (TGlittre-P) and verify its reliability. Methods: This is a cross-sectional study with 87 healthy children aged 6 to 14 years (mean 10.36 ± 2.32 years). Biometric and spirometry data were collected from all participants. On the same day, part of the sample (36 children included in the validation process) performed two 6MWT and two TGlittre-P (30-minute interval between them). The other part of the sample just performed two TGlittre-P for the reliability process. Pearson and Spearman correlation tests were used to verify the correlation between the time spent on the TGlittre-P and the distance walked in the 6MWT. The intraclass correlation coefficient (ICC) was also used to assess the reproducibility of the TGlittre-P. Results: The TGlittre-P showed a moderate negative correlation with the 6MWT (r = −0.490; p = 0.002; 95%CI −0.712 to −0.233). However, the behavior of the physiological variables that were monitored during the tests was similar and showed to be reproducible (ICC = 0.843; p = 0.000; 95%CI 0.695 to 0.911). Conclusion: The TGlittre-P proved to be a valid and reliable assessment of the functional capacity of healthy children aged 6 to 14 years.
