Psychological disposition and self-reported health among the ‘oldest-old’ in China
Bibliographic record
Abstract
This study contributes to our understanding of the ageing process by investigating whether particular psychological dispositions among older people are associated with healthy ageing. The study's objective is to further our knowledge about what constitutes ‘health’ for the ‘oldest-old’ (people aged 80 or more years) in China. It is recognised that apart from the absence of disease, good health is a subjective experience, and it is posited that self-reported health is associated with psychological disposition, or in other words, that an individual's personal attitudes, motivations, and beliefs condition their perception of health and illness. Using data from China's Longitudinal Healthy Longevity Survey (1998 and 2000 waves), we examine whether psychological disposition in 1998 had an independent effect on self-reported health in 2000. The study is based on a stratified random sample of 4,366 people aged 80 or more years. After introducing controls for health status and socio-demographic variables, the multivariate, longitudinal results demonstrate that a robust psychological disposition was indeed associated with good short-term, self-reported health. The findings also illustrate that the effect differed by age, for the relationship was significant for octogenarians and nonagenarians but insignificant for centenarians. Data limitations prevented an empirical investigation of the processes that underlie the relationship between psychological disposition and self-reported health.

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; a candidate call from one teacher head, not a consensus.
