You’ve probably heard of mindfulness. These days, it’s everywhere, like many ideas and practices drawn from Buddhist texts that have become part of mainstream Western culture.
But a review published today in the journal Perspectives on Psychological Science shows the hype is ahead of the evidence. Some reviews of studies on mindfulness suggest it may help with psychological problems such as anxiety, depression, and stress. But it’s not clear what type of mindfulness or meditation we need and for what specific problem.
The study, involving a large group of researchers, clinicians and meditators, found a clear-cut definition of mindfulness doesn’t exist. This has potentially serious implications. If vastly different treatments and practices are considered the same, then research evidence for one may be wrongly taken as support for another.
At the same time, if we move the goalposts too far or in the wrong direction, we might lose the potential benefits of mindfulness altogether.
Mindfulness receives a bewildering assortment of definitions. Psychologists measure the concept in differing combinations of acceptance, attentiveness, awareness, body focus, curiosity, nonjudgmental attitude, focus on the present, and others.
It’s equally ill-defined as a set of practices. A brief exercise in self-reflection prompted by a smart-phone app on your daily commute may be considered the same as a months-long meditation retreat. Mindfulness can both refer to what Buddhist monks do and what your yoga instructor does for five minutes at the start and end of a class.
To be clear, mindfulness and meditation are not the same thing. There are types of meditation that are mindful, but not all mindfulness involves meditation and not all meditation is mindfulness-based.
Mindfulness mainly refers to the idea of focusing on the present moment, but it’s not quite that simple. It also refers to several forms of meditation practices that aim to develop skills of awareness of the world around you and of your behavioral patterns and habits. In truth, many disagree about its actual purpose and what is and isn’t mindfulness.

Mindfulness has been applied to just about any problem you can think up - from relationship issues, problems with alcohol or drugs, to enhancing leadership skills. It’s being used by sportsmen to find “clarity” on and off the field and mindfulness programs are being offered at school. You can find it in workplaces, medical clinics, and old age homes.
More than a few popular books have been written touting the benefits of mindfulness and meditation. For example, in a supposedly critical review Altered Traits: Science Reveals How Meditation Changes your Mind, Brain and Body, Daniel Goleman argues one of the four benefits of mindfulness is improved working memory. Yet, a recent review of about 18 studies exploring the effect of mindfulness-based therapies on attention and memory calls into question these ideas.
Another common claim is that mindfulness reduces stress, for which there is limited evidence. Other promises, such as improved mood and attention, better eating habits, improved sleep, and better weight control are not fully supported by the science either.
And while benefits have limited evidence, mindfulness and meditation can sometimes be harmful and can lead to psychosis, mania, loss of personal identity, anxiety, panic, and re-experiencing traumatic memories. Experts have suggested mindfulness is not for everyone, especially those suffering from several serious mental health problems such as schizophrenia or bipolar disorder.
Another problem with mindfulness literature is that it often suffers from poor research methodology. Ways of measuring mindfulness are highly variable, assessing quite different phenomena while using the same label. This lack of equivalence among measures and individuals makes it challenging to generalise from one study to another.
