ABSTRACT
Purpose
To validate a self-report questionnaire to assess the central auditory processing in adults.
Methods
The instrument was tested and validated with 123 university students aged 18 to 59 years, without hearing changes or history of treatment for central auditory processing disorder. The participants were submitted to the Gaps-in-Noise and speech-in-white-noise tests. The cutoff scores for changes, sensitivity, and specificity were defined with statistical analysis.
Results
The instrument was developed with 21 questions related to health history, life habits, and hearing and learning complaints. After factor analysis, the questions related to life habits and health conditions were removed because they had a low factor loading. Thus, the final version of the scale comprised 13 questions. The first-order constructs and the diagnostic indicator achieved the required levels of reliability. The cutoff scores to indicate abnormal results in the Gaps-in- Noise and speech-in-white-noise tests were defined respectively as 6 and 5.
Conclusion
The scale obtained valid, reliable, and consistent results and enabled professionals to make inferences about auditory processing.
