Table 1 Operational definitions for feasibility categories
Feasibility category | Operational definition |
|---|---|
Non-compliant Examiner/Transcriber Report | Examiners and transcribers were instructed to note behavioral observations of noncompliance, defined as explicit refusal to complete the task, no response, or repeated off-task behavior. (Note: for the narration task, transcribers also classified samples in which the participant produced a task-related C-unit on 11 pages or fewer of the 16-page spreads presented). |
Total Sample Utterance Length | Samples in which the participant produced < 50 C-units in conversation or < 25 C-units in narration. (Note: this variable includes utterances that are partially or completely unintelligible, which is the sample used when calculating intelligibility). |
Analysis Set Utterance Length | Samples in which the participant produced < 50 C-units in conversation or < 25 C-units in narration. (Note: this variable includes only utterances that are complete and intelligible, which is the sample used when calculating lexical diversity, syntax, and dysfluency). |
Sample duration | Conversation samples that were at least 9.5 min in duration or narration samples in which the participant produced at least one task-related C-unit for each of the 16-page spreads presented. |
