Changes over Time in Physical Activity and Psychological Distress among Older Adults
Bibliographic record
Abstract
OBJECTIVE: While previous research has established that regular involvement in physical activity (PA) is associated with better mental health in old age, the socio-cognitive factors that mediate the association have only been partially tested. We examined whether changes in PA are associated with changes in distress during a 6-year period, and whether this association is mediated by changes in global self-esteem, mastery, and physical health status. METHOD: A residualized regression technique was used to examine changes over time in a national longitudinal survey of adults aged 65 years and older (n = 1327). RESULTS: There is a significant association between change in PA and change in distress. Separately, physical health status accounted for 30% of the explained variance of the longitudinal relation between PA and distress, while global self-esteem and mastery accounted for 39%. Combined, they accounted for 50% of the explained variance of PA on distress. CONCLUSION: These findings highlight the importance of psychosocial factors in the relation between PA and distress. Results suggest that PA interventions focused on improving mastery or self-worth, as well as physical fitness, may yield the greatest benefit in alleviating psychological distress.

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.
