Abstract
BACKGROUND: There is a need for a generic patient-reported outcome (PRO) that is patient-centric and offers sound properties for measuring the process and state of recovery from musculoskeletal trauma. This study describes the construction and initial validation of a new tool for this purpose. METHODS: A prototype tool was constructed through input of academic and clinical experts and patient representatives. After evaluation of individual items, a 9-item Satisfaction and Recovery Index (SRI) was subject to psychometric evaluation drawn from classical test theory. Subjects were recruited through online and clinical populations, from those reporting pain or disability from musculoskeletal trauma. The full sample (N = 129) completed the prototype tool and a corresponding region-specific disability measure. A subsample (N = 46) also completed the Short-Form 12 version 2 (SF12vs). Of that, a second subsample (N = 29) repeated all measures 3 months later. RESULTS: A single factor 'health-related satisfaction' was extracted that explained 71.1% of scale variance, Cronbach's alpha = 0.95. A priori hypotheses for cross-sectional correlations with region-specific disability measures and the generic Short-form 12 component scores were supported. The SRI tool was equally responsive to change, and able to discriminate between recovered/non-recovered subjects, at a level similar to that of the region-specific measures and generally better than the SF-12 subscales. CONCLUSION: The new SRI tool, as a measure of health-related satisfaction, shows promise in this initial evaluation of its properties. It is generic, patient-centered, and shows overall measurement properties similar to that of region-specific measures while allowing the potential benefit of comparison between clinical conditions. Despite early promising results, additional properties need to be explored before the tool can be endorsed for routine clinical use.

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 it
