A lifespan perspective on daily well-being: Differences in within-person variability by well-being domains and age.
Bibliographic record
Abstract
= 69.04, SD = 9.06, range = 55-94). Mixed effect location scale models suggested that older adults on average scored higher than young adults on daily self-acceptance, engagement, sense of purpose, autonomy, competence, personal growth, relatedness, vitality, and positive affect; scored lower on negative affect; and did not score differently on life satisfaction. Meanwhile, young adults experienced more daily within-person variability in all 11 well-being domains. Finally, multigroup, multilevel structural equation models showed that, at the between-person level, negative affect was more strongly tied to other well-being domains in young adults, while positive affect and vitality were more strongly tied to other well-being domains in older adults. At the within-person level, changes in one daily well-being domain were more strongly associated with changes in another 65% of the time for young adults and 33% of the time for older adults. The present study highlights differences in daily well-being processes tied to age and the larger role that daily events and experiences may play in shaping the short-term experiences of well-being in young adults' daily lives.

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.
