Introduction: Central Auditory Processing (CAP) screening refers to the method that will determine the need (or not) for referral for diagnosis. There is no universally accepted method and there is a shortage of validated tools. Objective: Analyze the results of an online hearing skills screening program (AudBility), a version aimed at schoolchildren between 6 and 8 years old, considering the influence of biological determinants, in addition to validating a tool through the analysis of sensitivity, specificity and correlation. Method: The first stage consisted of screening 154 students through a PAC screening program called AudBility, consisting of a self-perception questionnaire and tasks of sound localization (SL), temporal resolution (TR), pitch pattern sequence (PPS) and duration pattern sequence (DPS), auditory closure (AC), dichotic digits- binaural integration (DD) and figure-ground (FG). In the second stage, 112 children attended the institution's Audiology Laboratory, where basic audiological evaluation and PAC evaluation were performed. Parallel to the beginning of the screening, the teachers filled out a questionnaire about each child to help classify the child in group I (good school performance) or group II (school difficulty). Results: The groups were homogeneous in terms of sex, age and history of otitis. In the intragroup analysis, it was identified in group I that there was an influence of sex in the task DD to the right ear, influence of age in five tasks and the right ear in the tasks DD and PPS. In group II, there was an influence of gender on the task DD to the left ear, RT and PPS, influence of age on four tasks and the right ear on the tasks DD, PPS and DPS. In the correlation analysis, considering the group I with normal diagnosis of CAP, a correlation was found between 6 and 7 years of age in the tasks of AC, TR, DD, FG and PPS. At 8 years of age, there was a correlation in the DD and PPS tasks. The calculation of the sensitivity and specificity of each task identified that in the age group between 6 and 7 the accuracy values were: AC (76.9%); FG (61.6%); DD (78.8% to the right ear and 84.4% to the left ear in females and 63.2% to the left ear in males); TR (77.1%) and PPS (74.4% to the right ear and 82.4% to the left ear). At the age of 8, the values were: FG (76.5%); DD (71.7% to the female left ear and 77% to the male right ear); TR (56.5%) and PPS (54.1% to the right ear and 70% to the left ear). In the analysis of the self-perception questionnaire in the age group of 6 and 7 years old, the accuracy values were 64.8% and at 8 years old 72.8%. Children with sensorineural hearing loss had zero performance or at most 20% of correct answers in the figure-ground task. Conclusion: The variables age, sex and ear side influenced the results of the screening. Children with poor school performance had worse performance in screening compared to children with good school performance. The figure-ground task was the most difficult for children with sensorineural hearing loss. There were variations in the values of sensitivity and specificity between auditory tasks and age group. There was a correlation between screening and diagnosis in a greater number of tasks in the age group of 6 to 7 years. It is suggested as a minimum protocol the DD and RT tasks and that at the age of 8, the use of the self-perception questionnaire should be included (AU) | |
