Evaluation of the effectiveness of two clinical training procedures to elicit yes/no responses from patients with a severe acquired brain injury: a randomized single-subject design
Bibliographic record
Abstract
PRIMARY OBJECTIVE: Thirteen (10 males) participants with severe acquired brain injuries (ABI) were randomly assigned to two treatments, A or B (ABAB, BABA) in a crossover study to determine which treatment approach elicited more consistent and reliable yes/no responses. RESEARCH DESIGN: Treatment A consisted of an enriched stimulus environment, collaborative multidisciplinary interventions and additional yes/no response training, while Treatment B consisted of the standard hospital environment and interventions. MAIN OUTCOMES: An ANOVA showed no order effect (AB vs BA; p=0.60), but a trend (A vs B;p=0.07) towards statistical significance for increased responsiveness with treatment A. Inter-raterreliability (n=10) ranged from fair-to-good, intra class correlation (ICC) 0.51; 95% confidence interval (CI) (0.29-0.93). Post-hoc analyses showed statistically significant increased responsiveness for four participants with treatment A (p<0.001). CONCLUSION: Evidence is provided that enhanced communication strategies can improve responsiveness in a sub-group of participants with severe acquired brain injuries.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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; both teacher heads agree on what is shown here.
