There's a body of evidence that some adults that practice mediation will have anxiety or depression worsen instead of improve (~10-25% depending on the study).

There's a body of evidence that some adults that practice mediation will have anxiety or depression worsen instead of improve (~10-25% depending on the study). Even this simple activity with thousands of years of history is not well understood and can do harm. Other interventions have even less history. One thing about being an adult is that if mindfulness increases your anxiety you can choose not to practice it. Children are often forced into mental health interventions by schools. Imagine being compelled into doing something that worsens your mental health by someone trying to improve your mental health. The authors are correct that we should be selective about which students get which treatments. Often these are applied more broadly than is appropriate. The authors make no claim about the size of the impact of this practice, or the number of students negatively impacted.
