Effects of mindfulness training on cognition and wellbeing in healthy older adults
Bibliographic record
Abstract
Adults over the age of 65 years are now the fastest growing segment of the Canadian population. Although individual differences exist, aging is commonly associated with impairments in executive function and episodic memory. Previous studies have shown that mindfulness-based stress reduction (MBSR) can improve cognitive function in healthy younger adults, but no studies have yet examined this effect in older adults. The present study investigated the effectiveness of MBSR on improving executive function and episodic memory in older adult as well as its effectiveness in improving perceived stress and well-being. Ninety-seven healthy older adults were randomly assigned to either MBSR (n = 57) or an active control group (n = 40). It was hypothesized that compared with the control group, the MBSR group would display significant improvements in measures of executive function, episodic memory, mindfulness, mood, self-esteem, and quality of life. No clinically meaningful changes were found on any variable. In light of these results, the value of MBSR for this population is discussed.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
