RÉSUMÉ (en anglais)
Purpose: The main aim of the current study is to provide French-Canadian reference data for quantitative measures extracted from connected speech samples elicited by the Western Aphasia Battery-Revised (WAB-R) Picnic scene, a discourse task frequently used in clinical assessment of acquired language disorders.
Method: Our sample consisted of 62 healthy French-Canadian adults divided in two age groups: a 50 to 69 y.o. group and a 70 – 90 y.o. group.
Results: High inter-rater reliability scores were obtained for most of the variables. Most connected speech variables did not demonstrate an age effect. However, the 70 – 90 y.o. group produced more repetitions than the 50 to 69 y.o. group and displayed reduced communication efficiency (number of information content units per minute).
Conclusions: These findings contribute to building a reference dataset to analyze descriptive discourse production in clinical settings.
