Mindfulness Exercises Linked With Modest Improvements in Anxiety and Depression Symptoms

Research details

The review included 18 controlled studies with 1,150 participants.

Stand-alone mindfulness exercises were linked with greater improvements in anxiety symptoms than the comparison conditions.

They were also linked with greater improvements in depression symptoms.

The average benefits were small to moderate, not large or guaranteed for every person.

The authors said more research is needed among people with clinical diagnoses.

A review of 18 controlled studies found small-to-moderate average improvements after stand-alone mindfulness exercises, while noting that more research is needed among people with clinical diagnoses.

Effects of mindfulness exercises as stand-alone intervention on symptoms of anxiety and depression: Systematic review and meta-analysis

Plain Summary

A systematic review and meta-analysis published in *Behaviour Research and Therapy* in March 2018 examined whether stand-alone mindfulness exercises could help ease symptoms of anxiety and depression. “Stand-alone” means the exercises were studied on their own, rather than as one part of a larger psychotherapy programme.

The researchers combined findings from 18 controlled human studies involving 1,150 participants. Overall, people who practised the mindfulness exercises showed greater improvements in anxiety symptoms than people in the comparison groups. The same was true for depression symptoms.

The average effects were described as small to moderate. In everyday terms, this means the improvements were noticeable across the studies, but they were not large and did not occur equally for everyone. The statistical results were 0.39 for anxiety and 0.41 for depression; these figures are ways researchers compare the size of changes between groups, rather than scores that directly describe an individual’s wellbeing.

The results remained statistically significant after the authors adjusted for possible publication bias. This is a check for the possibility that studies with positive findings may be more likely to appear in journals than studies with less encouraging results.

Because this was a review of controlled studies, the findings provide evidence that mindfulness exercises may contribute to reductions in anxiety and depression symptoms compared with the control conditions used in the research. They do not show that mindfulness works for every person, or that it replaces professional care. They also should not be applied automatically to every form of meditation: the research specifically examined mindfulness exercises, and different meditation methods may have different effects.

The authors also noted that more research is needed among people with clinically diagnosed anxiety or depression. Overall, the review suggests that stand-alone mindfulness practice may offer a modest average benefit for symptoms, while leaving important questions about who benefits most and how well the findings apply to clinical populations.

Practical Takeaway

This review suggests that practising mindfulness on its own may lead to modest improvements in symptoms of anxiety and depression compared with control conditions. The conclusion is based on findings from 18 controlled studies, not on a promise that meditation will work for everyone. The research focused specifically on mindfulness exercises, so its results should not automatically be extended to every meditation method. It also included a need for more evidence involving people with clinically diagnosed conditions. In everyday terms, mindfulness may be a useful supportive practice for some people, but the study does not establish a cure, guarantee, or replacement for professional care.
