Insights
A new Auditory Processing Assessment Battery-European Portuguese (BAPA-PE) offers crucial central auditory processing evaluations for Portuguese speakers aged 5+. This tool provides vital normative data for early diagnosis and auditory training monitoring.
Area of Science:
- Audiology
- Neuroscience
- Speech and Hearing Sciences
Background:
- Growing demand for early Central Auditory Processing (CAP) assessment in Portuguese speakers.
- Existing assessment tools may not adequately cater to the specific linguistic and cultural nuances of European Portuguese speakers.
Purpose of the Study:
- Introduce the Auditory Processing Assessment Battery-European Portuguese (BAPA-PE), a novel CAP assessment tool.
- Provide normative data for BAPA-PE in European Portuguese-speaking children aged 5-12.
- Establish a reliable method for assessing CAP in young children.
Main Methods:
- Development and selection of six behavioral tests: Staggered Spondaic Words (SSW) for European Portuguese, Filtered Speech, Speech in Noise, Detection Interval in Noise, Duration Pattern, and Frequency Pattern.
- Normative data collection from 217 children (aged 5-12) with typical development and no ear pathology.
- Comprehensive audiological evaluations including pure tone audiometry, speech audiometry, impedance, and otoacoustic emissions.
Main Results:
- The BAPA-PE battery comprises six validated behavioral tests for CAP assessment.
- Normative scores for children aged 5-12 are reported for all six tests.
- Statistical analysis revealed significant effects of age on all test scores and ear effects on several tests.
Conclusions:
- The BAPA-PE is a validated tool for the clinical assessment of Central Auditory Processing in European Portuguese speakers.
- It is suitable for early identification of auditory processing disorders in children as young as 5.
- BAPA-PE aids in monitoring the effectiveness of auditory training interventions.
Abstract:
There is an increasing need for state-of-the-art Central Auditory Processing assessment for Portuguese native speakers, applicable as early as possible. As a contribution to answering this need, this paper presents a new battery for Central Auditory Processing assessment for European Portuguese applicable to children aged 5 and above, named BAPA-PE, providing information regarding test selection and development. The battery consists of six behavioral tests: Staggered Spondaic Words (SSW) for European Portuguese, Filtered Speech, Speech in Noise, Detection Interval in Noise, Duration, and Frequency Pattern. The normative data for children aged 5 to 12 are also reported. A sample was obtained of 217 subjects without ear pathology and with typical development. Each age group was composed of at least 30 children. All children were evaluated using pure tone audiometry, speech audiometry, impedance, and otoacoustic emissions. Normative scores are reported for each of the six auditory processing tests. The assessment is applicable to young children (aged 5 and 6). The statistical analyses showed significant effects in scores of Age for all tests and of Ear for several tests. The main result from the work presented, the Auditory Processing Assessment Battery-European Portuguese (BAPA-PE), is available for clinical use with normative data. This battery is a new tool for behaviorism assessment of European Portuguese speakers with suspected central auditory pathology and for monitoring the results of auditory training.
