AudBility: test-retest reliability in typically developing children aged 6 to 7 years

PURPOSE: to investigate the test-retest reliability of the AudBility program in typically developing children aged six-seven years. METHODS: 29 children, male and female, right-handed, native Portuguese speakers and adequate school performance for the age group studied, underwent previous meatoscopy, immittance measurements and the AudBility program was applied, composed of a self-perception questionnaire and auditory tasks, being analyzed the abilities of sound localization, auditory closure, figure-ground, dichotic digits test, temporal resolution, and temporal ordering of frequency and duration. The program was designed and reapplied with an interval of one week under the same conditions. The performance in each task was presented from central tendency and dispersion data and was conducted using the Intraclass Correlation Coefficient (ICC), based on the 95% confidence interval (CI). RESULTS: The analyses showed a positive and significant ICC (p<0.01) for the questionnaire and auditory tasks, except for auditory closure, in the right and left ears and figure-ground in the left ear. The questionnaire mean ICC was 0.742 and ranged from −0.012 to 0.698 for the auditory tasks. CONCLUSION: Based on mean results and upper limit of the CI, the findings showed agreement between moments, classified as good for the questionnaire and moderate to good for five of the seven auditory analyzed tasks (ICC>0.05 and <0.9). The results of the reliability study represent an important parameter for validating the program for the studied age group.
