Service encounter interactions of people living with moderate-to-severe post-stroke aphasia in their community
Bibliographic record
Abstract
Background: Access to the community is recognised as a need as well as a right for people living with a disability, including people living with aphasia (PLWA). Although studies have shown factors that hinder or support participation of PLWA, few examined naturally occurring interactions outside the home.Aims: This qualitative study aimed to describe the structure of natural interactions occurring between people with aphasia and individuals at the checkout in service encounters.Methods and Procedure: Six participants with moderate-to-severe expressive post-stroke aphasia were video-recorded during commercial interactions within their community environment. Data collection took place in grocery stores, supermarkets, restaurants, drug stores, coffee shops, specialised shops, and a movie theatre. A total of 20 commercial interactions were analysed using conversation analysis.Outcomes and Results: The interactions between PLWA and checkout assistants during payment were characterised by a sequence of four communication stages based on mutual agreement of (1) their availability for the commercial transaction, (2) the item(s) that would be purchased, (3) the price, and (4) the fact that the interaction was over. The second and third parts of the sequence were more challenging in terms of physical access to the desired item(s) or its representation in stage two and access to a visual display of the price in stage three influenced the communication accessibility of the stores.Conclusions: The present findings suggest that PLWA can successfully participate in interactions involving the purchase of goods, even if aphasia is severe, as these interactions are structured by communication and four stages of mutual agreement. During rehabilitation, speech–language pathologists could help prepare PLWA to carry out commercial transactions in self-selected shops to support active community participation post-rehabilitation.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
