Negative Life Events and Age-Related Decline in Mastery: Are Older Adults More Vulnerable to the Control-Eroding Effect of Stress?
Bibliographic record
Abstract
OBJECTIVES: The purpose of this study was to see if exposure to life events influences age-related decline in control. METHODS: The data came from a large, nationally representative sample of Canadians aged 18 and older (n = 17, 291). We examined the principal research question by testing for an interaction between age, life events, and mastery using linear regression, both cross-sectionally and over time. RESULTS: Similar to previous work, there was a nonlinear association between age and mastery. The data suggested that exposure to life events was associated with lower levels of perceived control at any age, but that the impact of stress exposure was stronger in older adults. This effect was also evident for change in mastery over time. DISCUSSION: The findings from this study suggest that exposure to life events is an important, yet overlooked, determinant of age-related decline in control. Loss of personal and social resources may be the reason older adults appear more vulnerable to the negative effects of stress.

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.
