Associations between global mental health and response to an app-based meditation intervention in myeloproliferative neoplasm patients

A study examining the effects of smartphone meditation app Calm on depression, anxiety, and sleep disturbance in 80 MPN patients found that patients with lower Global Mental Health (GMH) scores at baseline (which were associated with higher levels of depression) experienced greater reductions in depression than patients with higher baseline GMH scores after using the app for 10 minutes every day for 4 weeks. A similar effect was seen in patients with anxiety.
