Digital program eases anxiety and depression in chronic illness trial

The yoga pose came after the hard part: 825 adults had completed a 12-week study without leaving home. Across 13 countries, Puneeta Tandon's team at the University of Alberta tested eMPower, a digital program combining guided movement, breathing and meditation, coping-skills training and education about chronic disease. The results, published in PLOS Medicine on Aug. 20, 2026, point to a practical way to address the anxiety, depression and fatigue that often accompany long-term illness.

Participants were randomly assigned to a waitlist, a self-directed version of eMPower, or the same program with weekly telephone check-ins from trained nonclinicians. Anxiety and depression were scored on a standard scale running from 0 to 42. At 12 weeks, the supported version showed a 2.9-point greater improvement than the control group, with a 95% confidence interval of 2.0–3.8; quality of life also improved and fatigue fell.

The phone calls were not clearly necessary for everyone. In an exploratory analysis, the self-directed program produced a 2.6-point greater improvement than the control group, with a 95% confidence interval of 1.8–3.5. Researchers found no significant difference between the two program formats, but the trial was not designed or powered to compare them directly. The finding suggests that limited human support might be reserved for participants who need it most, rather than made mandatory for every user.

And so, concretely? Someone managing severe fatigue, limited mobility, distance from a specialist center or an overloaded schedule could access symptom-management exercises from home, without adding another appointment. That matters because more than half of adults living with chronic physical conditions experience anxiety, depression or fatigue, while access to support is constrained by geography, cost, mobility barriers and shortages of trained clinicians. The program does not replace medication or mental-health care when those are needed; it offers a starting point alongside them.

The evidence still has edges. The study primarily included women with higher education, measured outcomes only for 12 weeks and cannot yet establish how durable the benefits are or how well they transfer to other populations. Still, the 84% follow-up completion rate in a fully online study—including almost one in four participants over 65—suggests that a cross-condition format can hold people's attention while researchers continue testing where it works best.
