Meditation, especially mindfulness meditation, is another strategy that has gained popularity in the treatment of anxiety and depression. Mindfulness has been defined as “the practice of maintaining a nonjudgmental state of heightened or complete awareness of one’s thoughts, emotions, or experiences on a moment-to-moment basis.”⁴⁰ A 2014 systematic review and meta-analysis of 47 trials with 3515 participants found that mindfulness meditation programs led to clinically significant moderate reductions in anxiety.⁴¹ Smaller effects were found for depression.

Nevertheless, meditation may be beneficial as an adjunctive treatment for depression. A small randomized trial (N = 25) compared an adjunctive breathing-based meditation intervention with a waitlist control (delayed yoga) in patients with unipolar major depression who failed to respond to at least 8 weeks of antidepressant treatment.⁴² The meditation intervention consisted of a group program with sitting meditation, breathing exercises, and yoga postures. Participants engaged in the meditation intervention for 2 to 3.5 hours per day for 8 weeks and demonstrated significant improvement in depression symptoms compared with the control group.⁴²

Acupuncture. A 2018 meta-analysis of 64 studies (N = 7104) suggests that acupuncture results in a small-to-moderate reduction in depressive symptoms when compared to no treatment, control/sham acupuncture, or medication.⁴³ Furthermore, acupuncture plus medication compared to medication alone results in a higher reduction in depressive symptoms without an increase in adverse events.⁴³

Additionally, a 2019 analysis of 10 systematic reviews found acupuncture to be more effective than control/sham acupuncture in the treatment of general anxiety.⁴⁴ It should be noted, however, that a lot of heterogeneity and potential for bias existed across all of the studies. The studies analyzed were very low to low in quality. Thus, the evidence is insufficient to strongly recommend the use of acupuncture for depression or anxiety, although acupuncture is a safe intervention with low rates of adverse events.

Emotional support animals: Beneficial, but evidence is weak

Emotional support animals are gaining in popularity with Americans who have mood disorders. An important distinction must be made, however, between service animals and emotional support animals. A service animal is one “that is individually trained to do work or perform tasks for the benefit of an individual with a disability, including a physical, sensory, psychiatric, intellectual, or other mental disability.”⁴⁵ Under the Americans with Disabilities Act (ADA), service animals are limited to dogs, and, in some cases, specially trained miniature horses. Psychiatric service dogs can be trained to do anything from reminding their owner to take medicine to stopping self-mutilation activities.
