“…To our knowledge, previous research did not report details on individual cohesion variables but rather an overall score of reliability on all cohesion variables, which might explain discrepancies. All microstructural variables studied in the present paper obtained excellent reliability, consistent with previous studies in structured (e.g., Boucher et al., 2022; Brisebois et al., 2022; Nicholas & Brookshire, 1993b) and unstructured tasks (Leaman & Edmonds, 2021).…”

Background Discourse analysis has recently received much attention in the aphasia literature. Even if post‐stroke language recovery occurs throughout the longitudinal continuum of recovery, very few studies have documented discourse changes from the hyperacute to the chronic phases of recovery. Aims To document a multilevel analysis of discourse changes from the hyperacute phase to the chronic phase of post‐stroke recovery using a series of single cases study designs. Methods & Procedures Four people with mild to moderate post‐stroke aphasia underwent four assessments (hyperacute: 0–24 h; acute: 24–72 h; subacute: 7–14 days; and chronic: 6–12 months post‐onset). Three discourse tasks were performed at each time point: a picture description, a personal narrative and a story retelling. Multilevel changes in terms of macro‐ and microstructural aspects were analysed. The results of each discourse task were combined for each time point. Individual effect sizes were computed to evaluate the relative strength of changes in an early and a late recovery time frame. Outcomes & Results Macrostructural results revealed improvements throughout the recovery continuum in terms of coherence and thematic efficiency. Also, the microstructural results demonstrated linguistic output improvement for three out of four participants. Namely, lexical diversity and the number of correct information units/min showed a greater gain in the early compared with the late recovery phase. Conclusions & Implications This study highlights the importance of investigating all discourse processing levels as the longitudinal changes in discourse operate differently at each phase of recovery. Overall results support future longitudinal discourse investigation in people with post‐stroke aphasia. What This Paper Adds What is already known on the subjectMulti‐level discourse analysis allows for in‐depth analysis of underlying discourse processes. To date, very little is known on the longitudinal discourse changes from aphasia onset through to the chronic stage of recovery. This study documents multi‐level discourse features in four people with mild to moderate aphasia in the hyperacute, acute, subacute and chronic stage of post‐stroke aphasia recovery. What this paper adds to existing knowledgeThe study found that most discourse variables demonstrated improvement throughout time. Macrostructural variables of coherence and thematic units improved throughout the continuum whereas microstructural variables demonstrated greater gains in the early compared to the late period of recovery. What are the potential or actual clinical implications of this work?This study suggests that multilevel discourse analysis will allow a better understanding of post‐stroke aphasia recovery, although more research is needed to determine the clinical utility of these findings. Future research may wish to investigate longitudinal discourse recovery in a larger sample of people with aphasia with heterogenous aphasia profiles and severities.

“…Also, none reported functional impairments in their daily life activities. Fourth, although the sample size is not very large, this study contributes to a more standardized assessment of spoken discourse variables in Canadian French, as previous work conducted by our research team (Boucher et al, 2022). Fifth, the sample had an overrepresentation of women (64% of the sample) and highly-educated individuals, similar to most studies conducted in the Québec French population (e.g., Bourgeois-Marcotte et al, 2015;Callahan et al, 2010;Marcotte et al, 2017).…”

“…IRR was conducted on 10 samples (20%) of the videoconference group by a second-rater (N.D.) and 17 samples (36%) of the in-person group. IRR for the in-person group have been reported in a previous conducted on a larger sample of participants (Boucher et al, 2022), but have been recalculated using only participants from the present study and by adding confidence interval and standard error measurement. To determine consistency between raters, ICCs were calculated on the total number of TUs, the sample's duration, and all the microstructural variables extracted from CLAN.…”

Purpose: During the COVID-19 pandemic, clinicians and researchers have increasingly used remote online assessments to pursue their activities, but mostly with tests not validated for videoconference administration. This study aims to validate the remote online administration of picture description in Canadian French neurotypical speakers and to explore the thematic unit (TU) checklist recently developed. Method: Spoken discourse elicited through the picture description task of the Western Aphasia Battery–Revised (WAB-R) was collected from Canadian French neurotypical speakers from Québec aged between 50 and 79 years old. Forty-seven participants completed the task in person, and 49 participants completed the task by videoconference. Videos of each discourse sample were transcribed using CHAT conventions. Microstructural variables were extracted using the CLAN (Computerized Language ANalysis) program, whereas thematic informativeness was scored for each sample using TUs. Chi-square tests were conducted to compare both groups on each TU; t tests were also performed on the total score of TUs and microstructural variables. Results: Groups were matched on sex, age, and education variables. The t tests revealed no intergroup difference for the total TU score and for the microstructural variables (e.g., mean length of utterances and number of words per minute). Chi-square tests showed no significant intergroup difference for all 16 TUs. Conclusions: These findings support remote online assessment of the picnic scene of the WAB-R picture description in Canadian French neurotypical speakers. These results also validate the 16 TUs most consistently produced. The use of videoconference could promote and improve the recruitment of participants who are usually less accessible, such as people using assistive mobility technologies.
