Abstract: Purpose: Lexical performance in discourse is of considerable interest in acquired communication disorders. The transcription-free core lexicon measure evaluates the most typical words a person uses during communication. This study aimed (a) to develop core lexicon lists in Laurentian French speakers without brain injury and (b) to assess their psychometric properties. Method: Spoken discourse was elicited using the picture description task from the Western Aphasia Battery-Revised (WAB-R; Kertesz, 2006) and the Cinderella Story Telling (CST) task. Participants were Laurentian French speakers from Quebec, aged 50-79 years, without brain injury. Sixty-six completed the WAB-R task, and 48 completed the CST task. Core noun and verb lists were created using the CLAN program, including words produced by at least 50% of the sample. Two raters scored all audio samples. Intra- and interrater reliability and long-term test-retest reliability were calculated. Construct validity was examined through correlations with micro- and macrostructural discourse measures. Results: Four core lexicon lists were generated. For theWAB-R, 19 nouns and five verbs were identified; for the CST, 19 nouns and 16 verbs were identified. Intrarater reliability was excellent across variables, and interrater reliability was excellent for all core noun lists and CST core verbs and good for WAB-R core verbs. Long-term test-retest reliability ranged from poor to moderate across measures. Core lexicon scores were significantly and positively correlated with 12 macrostructural and ninemicrostructural variables. Conclusions: This study supports the rater reliability and construct validity of core lexicon measures in Laurentian French speakers across two discourse tasks. It also provides the first long-term test-retest reliability data for core lexicon scoring, offering insights that guide its clinical and research applications.
