Recently, AVQI was successfully modified to be more representative and ecologically valid because the internal consistency of AVQI was balanced out through equal proportion of the 2 speech types. The present investigation aims to explore its external validation in a large data set.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods:<\/jats:title>\n                    <jats:p>An expert panel of 12 speech-language therapists rated the voice quality of 1058 concatenated voice samples varying from normophonia to severe dysphonia. The Spearman rank-order correlation coefficients ( r) were used to measure concurrent validity. The AVQI\u2019s diagnostic accuracy was evaluated with several estimates of its receiver operating characteristics (ROC).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>Finally, 8 of the 12 experts were chosen because of reliability criteria. A strong correlation was identified between AVQI and auditoryperceptual rating ( r = 0.815, P = .000). It indicated that 66.4% of the auditory-perceptual rating\u2019s variation was explained by AVQI. Additionally, the ROC results showed again the best diagnostic outcome at a threshold of AVQI = 2.43.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions:<\/jats:title>\n                    <jats:p>This study highlights external validation and diagnostic precision of the AVQI version 03.01 as a robust and ecologically valid measurement to objectify voice quality.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/0003489416636131","type":"journal-article","created":{"date-parts":[[2016,3,7]],"date-time":"2016-03-07T21:23:18Z","timestamp":1457385798000},"page":"571-583","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":116,"title":["External Validation of the Acoustic Voice Quality Index Version 03.01 With Extended Representativity"],"prefix":"10.1177","volume":"125","author":[{"given":"Ben","family":"Barsties","sequence":"first","affiliation":[{"name":"Faculty of Medicine and Health Sciences, University of Antwerp, Belgium"},{"name":"Medical School, Hochschule Fresenius University of Applied Sciences, Hamburg, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Youri","family":"Maryn","sequence":"additional","affiliation":[{"name":"Faculty of Medicine and Health Sciences, University of Antwerp, Belgium"},{"name":"European Institute for ORL, Sint-Augustinus Hospital, Antwerp, Belgium"},{"name":"Faculty of Education, Health & Social Work, University College Ghent, Belgium"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2016,3,7]]},"reference":[{"key":"bibr1-0003489416636131","doi-asserted-by":"publisher","DOI":"10.1016\/j.anl.2014.11.001"},{"key":"bibr2-0003489416636131","doi-asserted-by":"publisher","DOI":"10.1159\/000200768"},{"key":"bibr3-0003489416636131","unstructured":"Barsties B, Maryn Y.
