Online Single-Session Intervention to Foster Connection in Older Adults: Pilot Trial
Bibliographic record
Abstract
Purpose Social disconnection in later life significantly impacts emotional and psychological well-being, yet scalable, evidence-based interventions remain limited. This pilot randomized controlled trial evaluated the preliminary efficacy of a single-session online Awareness, Courage, and Love (ACL) intervention in enhancing interpersonal closeness and well-being among older adults. Method Sixty-four community-dwelling older adults (aged ≥60) were randomly assigned to the ACL intervention group ( n = 32) or a waitlist control ( n = 32). Primary and secondary outcomes, including interpersonal closeness and mental health outcomes, were assessed at baseline, post-intervention, and 1-month follow-up. Results Interpersonal closeness significantly increased from baseline to post-intervention in both groups, with a nonsignificant trend favoring the ACL group. The ACL group displayed significant improvements in depressive symptoms from baseline to post-intervention, and from post-intervention to 1-month follow-up. Conclusion This pilot trial shows preliminary efficacy of a single-session ACL intervention, motivating multi-session testing to assess durability.

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.
