# Central auditory processing skill self-perception scale (CAPSSPS) and behavioral tests: a study in young adults with and without central auditory processing disorder

## TL;DR

This study compares auditory processing skills in young adults with and without central auditory processing disorder using a self-perception scale and behavioral tests.

## Contribution

The CAPSSPS questionnaire is shown to detect additional auditory processing issues beyond previously known skills in young adults.

## Key findings

- CAPSSPS and behavioral tests showed significant differences between groups with and without CAPD.
- Young adults with CAPD had altered temporal resolution and binaural interaction skills.
- The CAPSSPS can identify issues in temporal ordering and binaural interaction in addition to traditional measures.

## Abstract

To analyze the results of the Central Auditory Processing Disorder. Central Auditory Processing Skill Self-Perception Scale (CAPSSPS) and compare different auditory skills in young adults with and without Central Auditory Processing Disorder (CAPD).

Cross-sectional and prospective study. Thirty-two individuals participated in the study, who were native Brazilian Portuguese speakers, non-bilingual, non-musicians, and not exposed to noise, with normal results in basic audiological assessments, no cognitive or otological complaints, with or without difficulties related to Central Auditory Processing, divided into two groups: participants without CAPD (G1) and participants with CAPD (G2). All participants underwent Anamnesis, Visual Inspection of the External Auditory Canal, Pure Tone Audiometry, Speech Audiometry, Acoustic Immittance Measures, Behavioral Tests of Central Auditory Processing, and the CAPSSPS questionnaire.

There was a significant difference between the groups with and without CAPD when comparing the CAPSSPS questionnaire and the Test of Frequency Pattern (TPF) - Auditec, Masking Level Difference (MLD), and the Gaps in Noise (GIN) tests for the left ear.

The CAPSSPS questionnaire demonstrated the possibility of screening for other altered auditory skills, in addition to auditory closure and temporal resolution in young adult populations, including temporal ordering for frequency and binaural interaction. Furthermore, young adult individuals showed greater alterations in auditory skills of temporal resolution, temporal ordering for frequency, and poorer performance in binaural interaction skill.

Analisar o resultado da Escala de Autopercepção de Habilidades do Processamento Auditivo Central (EAPAC) e comparar as diferentes habilidades auditivas em adultos jovens com e sem Transtorno do Processamento Auditivo Central (TPAC).

Estudo de caráter transversal e prospectivo. Participaram do estudo 32 indivíduos, falantes do portugues brasileiro, não bilingues, musicistas ou expostos ao ruído, com normalidade na avaliação audiológica básica, sem queixas cognitivas e otológicas, com ou sem dificuldades relacionadas ao Processamento Auditivo Central (PAC), distribuídos em dois grupos: participantes sem TPAC (G1) e participantes com TPAC (G2). Todos foram submetidos a Anamnese, Inspeção Visual do Meato Acústico Externo, Audiometria Tonal Liminar, Logoaudiometria, Medidas de imitância acústica, Testes Comportamentais do Processamento Auditivo Central e ao questionário EAPAC.

Houve diferença significativa entre os grupos com e sem TPAC, quando comparado o questionário EAPAC e nos testes Teste Padrão de Frequência(TPF) - Auditec, Masking Level Difference(MLD) e o Gap in Noise (GIN) para a orelha esquerda.

O questionário EAPAC demonstrou a possibilidade de rastrear outras habilidades auditivas alteradas, além de fechamento auditivo e resolução temporal no público adulto jovem, sendo elas ordenação temporal e interação binaural. Ademais, os indivíduos adultos jovens apresentaram maior alteração nas habilidades auditivas de resolução temporal, ordenação temporal e pior desempenho na habilidade de interação binaural.
