Cumulative Exposure to Social Isolation and Longitudinal Changes in Life Satisfaction among Older Adults
Bibliographic record
Abstract
This study examines the longitudinal association between cumulative exposure to social isolation and life satisfaction and whether this association differs by gender. Using seven waves of the Korean Longitudinal Study of Aging from 2006 to 2018 (3,543 adults aged 65 or older), fixed effects models were estimated. Cumulative social isolation was longitudinally associated with a decline in life satisfaction in older adults. Gender-specific analyses revealed that older women exposed to cumulative social isolation continued to experience a decline in life satisfaction up to the fourth and subsequent waves of exposure (relative to the initial wave in which there was no social isolation; b = −13.038, p < .001). In contrast, a decline in life satisfaction associated with cumulative social isolation was less pronounced among older men ( b = −6.200 for the fourth and subsequent waves of exposure, p < .05). Cumulative social isolation can be a persistent risk factor for life satisfaction in older adults, particularly older women. The study’s findings hold important implications for programs aimed at reducing social isolation and improving psychological well-being among older adults.

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.
