Test-retest reliability of dichotic listening test in younger adults with normal hearing

Abstract

BackgroundDichotic listening refers to simultaneously stimulating both ears but with two different stimuli. Dichotic listening tasks were used in the audiological test battery to assess auditory processing abilities in children and adults. Studies have reported the dichotic consonant-vowel syllable test’s test-retest reliability in different attentional manipulation conditions. The objectives are to measure the intra- and inter-test reliability of dichotic consonant vowel tests in young, healthy individuals.MethodsSixty participants aged 18–28 with normal hearing sensitivity were recruited for the study. To measure the intra- and inter-test reliability, the dichotic consonant-vowel test was conducted within and between days. The single correct and double correct scores were calculated.ResultsThe analysis of the study showed good test-retest reliability for the single correct and double correct scores of the dichotic consonant-vowel test based on Cronbach’s alpha values and Friedman’s tests.ConclusionThis study’s findings indicate that the dichotic test is a stable measure that can be clinically used for evaluation and can be used for research studies.
