Answer this question to the best of your ability:
Why has the evidence for mindfulness meditation's effectiveness been called into question?
Some of the findings on mindfulness meditation have been called into question due to issues with study design, such as small sample sizes or problematic experimental designs. However, there are a handful of key areas, including depression, chronic pain, and anxiety, in which well-designed, well-run studies have shown benefits for patients engaging in a mindfulness meditation program, with effects similar to other existing treatments.
