Mindfulness-based stress reduction and loneliness in older adults: two randomized controlled trials

Loneliness is one of the most robust risk factors for morbidity and accelerated mortality among older adults, and effective interventions are needed. However, interventions to reduce loneliness have shown limited success, especially in this population. Indeed, research suggests that simply increasing social contact might not combat loneliness; instead, addressing the cognitive and emotional mechanisms of loneliness might be more effective. Here, in two randomized controlled trials (RCT), we explored whether mindfulness training could reduce loneliness.

This study tested an 8-week Mindfulness-Based Stress Reduction (MBSR) program on loneliness in older adults across two RCTs. Study 1 compared MBSR to a waitlist (WL) control, and Study 2 compared MBSR to the Health Enhancement Program (HEP).

From baseline to follow-up, MBSR significantly reduced loneliness compared to WL in Study 1 (b = -1.680, SE = 0.273, 95% CI [-3.325, -0.034], p = .045, β = -0.402). In Study 2, MBSR and HEP both reduced loneliness (main effect of time: b = -3.598, SE = 0.957, 95% CI [-5.481, -0.1.716], p < .001, β = -0.378), with no significant difference between conditions. Baseline depressive symptoms, perceived stress, sex, age, or homework did not reliably moderate effects on reducing loneliness.

These findings suggest that both MBSR and HEP may be promising approaches to addressing loneliness in older adults with effects lasting for months.
