Yet, their utility for use in clinical assessment and empirical research relies critically on the precision\n and test\u2010retest repeatability of the measure.<jats:bold>Purpose:<\/jats:bold>To determine how subcortical\/cortical classes of auditory neural responses directly compare in terms of their internal consistency and test\u2010retest reliability within and between listeners.<jats:bold>Research Design:<\/jats:bold>A descriptive\n cohort study describing the dispersion of electrophysiological measures.<jats:bold>Study Sample:<\/jats:bold>Eight young, normal-hearing female listeners.<jats:bold>Data Collection and Analysis:<\/jats:bold>We recorded auditory brainstem responses (ABRs), brainstem frequency-following responses (FFRs), and cortical (P1-N1-P2)\n auditory-evoked potentials elicited by speech sounds in the same set of listeners. We reassessed responses within each of four different test sessions over a period of 1 mo, allowing us to detect possible changes in latency\/amplitude characteristics with finer detail than in previous studies.<jats:bold>Results:<\/jats:bold>Our\n findings show that brainstem and cortical amplitude\/latency measures are remarkably stable; with the exception of slight prolongation of the P1 wave, we found no significant variation in any response measure. Intraclass correlation analysis revealed that the speech-evoked FFR amplitude and\n latency measures achieved superior repeatability (intraclass correlation coefficient &gt;0.85) among the more widely used obligatory brainstem (ABR) and cortical (P1-N1-P2) auditory-evoked potentials. Contrasting these intersubject effects, intrasubject variability (i.e., within-subject coefficient\n of variation) revealed that while latencies were more stable than amplitudes, brainstem and cortical responses did not differ in their variability at the single subject level.<jats:bold>Conclusions:<\/jats:bold>We conclude that (1) the variability of auditory neural responses increases with ascending level\n along the auditory neuroaxis (cortex &gt; brainstem) between subjects but remains highly stable within subjects and (2) speech-FFRs might provide a more stable measure of auditory function than other conventional responses (e.g., click-ABR), given their lower inter- and intrasubject variability.<\/jats:p>","DOI":"10.3766\/jaaa.16167","type":"journal-article","created":{"date-parts":[[2017,5,3]],"date-time":"2017-05-03T14:49:19Z","timestamp":1493822959000},"page":"164-174","source":"Crossref","is-referenced-by-count":44,"title":["Test\u2010Retest Reliability of Dual-Recorded Brainstem versus Cortical Auditory-Evoked Potentials to Speech"],"prefix":"10.3766","volume":"29","author":[{"given":"Gavin M.","family":"Bidelman","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Monique","family":"Pousson","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Calli","family":"Dugas","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Amy","family":"Fehrenbach","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"2087","container-title":["Journal of the American Academy of Audiology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.ingentaconnect.com\/content\/aaa\/jaaa\/2018\/00000029\/00000002\/art00009","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,2,6]],"date-time":"2025-02-06T08:06:16Z","timestamp":1738829176000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.ingentaconnect.com\/content\/10.3766\/jaaa.16167"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2018,2,1]]},"references-count":0,"journal-issue":{"issue":"2","published-print":{"date-parts":[[2018,2,1]]}},"alternative-id":["1050-0545(20180201)29:2L.164;1-"],"URL":"https:\/\/doi.org\/10.3766\/jaaa.16167","relation":{},"ISSN":["1050-0545"],"issn-type":[{"value":"1050-0545","type":"print"}],"subject":[],"published":{"date-parts":[[2018,2,1]]}}}
