DEVELOPMENT OF A PERSON-CENTERED INDEX OF AGING WELL IN CANADA AND MEXICO
Bibliographic record
Abstract
Starting from the results of a qualitative study in Canada and existing literature in different contexts, an index capturing most of the domains used in definitions of successful aging was constructed, with a particular focus on lay perspectives. The index was developed using data gathered in 2014 from 663 Canadian participants in the International Mobility in Aging Study (IMIAS) and 15,698 Mexican participants in the Mexican Healthy Aging Study (MHAS). It was computed as a continuous score (0 to 100) containing health-related components (ADL disability, mobility disability, pain, self-rated health, and cognitive function), and psychosocial components (mood, productive activities, social relations, life satisfaction, and self-mastery). Mean scores on aging well were 80 among Canadian older adults and 59 among Mexican participants. The detailed scores indicate aspects of the health and psychosocial well-being that deserve improvement according to older adults themselves, particularly pain management in Canada and mobility disability in Mexico.

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.
