Abstract
BACKGROUND: Measuring the care experience at end-of-life (EOL) to inform quality improvement is a priority in many countries. We validated the CaregiverVoice survey, a modified version of the VOICES questionnaire, completed by bereaved caregivers to capture perceptions of care received in the last three months of a patient's life. METHODS: We conducted a retrospective survey of bereaved caregivers representing palliative care patients who died in a residential hospice and/or received palliative homecare in Ontario, Canada. Statistical analyses were completed to establish construct and concurrent validity, as well as reliability of the survey. RESULTS: Responses were obtained from 906 caregivers: 330 surveyed from homecare agencies and 576 from hospices. The CaregiverVoice survey demonstrated concurrent validity in scores correlating to FAMCARE2 items, and construct validity in performing according to expected patterns, e.g., correlation of scores to qualitative perceptions and significant variability based on care contexts such as place of death and setting of care (p < 0.01). Reliability was exhibited in good inter-item correlation of ratings for specific care settings and no significant differences in ratings regardless of whether up to a year had passed since death of patient. CONCLUSIONS: The CaregiverVoice survey demonstrated validity and reliability in the populations assessed. This survey represents one common measure that can be standardized across multiple care settings and is useful for assessing the care experience that can help inform local and national quality improvement activities.

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
