The purpose of this post hoc study was to further describe lexical and morphosyntactic changes associated with changes in content production.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Method<\/jats:title>\n            <jats:p>Existing probe data from 8 persons with aphasia who had completed CAAST were used to complete analyses of morphosyntactic production, lexical diversity, and novelty of content. Language analyses were completed using discourse samples obtained at numerous pretreatment and posttreatment intervals.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Results<\/jats:title>\n            <jats:p>All participants demonstrated gains in morphosyntactic language output for treated items, which extended to untreated sets for 7 participants. All 8 increased in production of novel content. Lexical diversity increases were evident for most participants. Although there were some similarities in language changes, there was substantial variability across response profiles.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Conclusion<\/jats:title>\n            <jats:p>CAAST, previously associated with positive treatment effects for production of accurate content, also appears to facilitate acquisition and generalization of morphosyntactic complexity, lexical diversity, and novelty of content for individuals with nonfluent aphasia. Further investigation is needed to determine causality and appropriate clinical application.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Supplemental Material<\/jats:title>\n            <jats:p>\n              <jats:ext-link xmlns:xlink=\"http:\/\/www.w3.org\/1999\/xlink\" ext-link-type=\"uri\" xlink:href=\"https:\/\/doi.org\/10.23641\/asha.5912530\">https:\/\/doi.org\/10.23641\/asha.5912530<\/jats:ext-link>\n            <\/jats:p>\n          <\/jats:sec>","DOI":"10.1044\/2018_ajslp-16-0193","type":"journal-article","created":{"date-parts":[[2018,3,1]],"date-time":"2018-03-01T23:30:58Z","timestamp":1519947058000},"page":"323-335","source":"Crossref","is-referenced-by-count":6,"title":["Language Changes Following Combined Aphasia and Apraxia of Speech Treatment"],"prefix":"10.1044","volume":"27","author":[{"given":"Lisa D.","family":"Bunker","sequence":"first","affiliation":[{"name":"VA Salt Lake City Health Care System, UT"},{"name":"The University of Utah, Salt Lake City"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sandra","family":"Wright","sequence":"additional","affiliation":[{"name":"VA Salt Lake City Health Care System, UT"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Julie L.","family":"Wambaugh","sequence":"additional","affiliation":[{"name":"VA Salt Lake City Health Care System, UT"},{"name":"The University of Utah, Salt Lake City"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1310","reference":[{"key":"e_1_3_2_2_1","doi-asserted-by":"publisher","DOI":"10.1044\/2015_AJSLP-14-0127"},{"key":"e_1_3_2_3_1","volume-title":"The Verb and Sentence Test (VAST)","author":"Bastiaanse R.","year":"2002"},{"key":"e_1_3_2_4_1","volume-title":"TONI-4, Test of Nonverbal Intelligence\u2013Fourth Edition","author":"Brown L.","year":"2010"},{"key":"e_1_3_2_5_1","volume-title":"MATTR user manual (CASPR research report 2007\u201305)","author":"Covington M.
