Behavioral Activation and Mindfulness Interventions in Reducing Loneliness and Improving Well-Being in Older Adults: The HEAL-HOA Randomized Clinical Trial
What it found
A randomised trial of 1,151 older adults living in poverty, alone, and digitally excluded tested telephone-delivered behavioural activation and mindfulness against a befriending control. The intervention, delivered as eight 30-minute calls over one month by trained laypeople who were themselves older adults with lived experience of loneliness, produced significantly greater reductions in loneliness at 12 months than befriending.
Why it matters for practice
Befriending is the default intervention commissioned for loneliness in this population, so a trial in which it loses to a structured, peer-delivered alternative is a direct challenge to current commissioning defaults rather than an incremental finding. Programme managers choosing between models for isolated older adults should treat this as evidence that intervention structure and technique matter more than simple social contact.
