A type of “mindfulness” therapy that helps people become more aware of their emotions may help prevent a relapse of depression, a new meta-analysis finds.
People in the study who received this type of therapy, called mindfulness-based cognitive therapy (MBCT), were 31 percent less likely to experience a relapse of depression beyond the first year compared with those who did not receive this type of therapy, according to the findings which were published in the journal JAMA Psychiatry.
Willem Kuyken, Ph.D., of the University of Oxford, England, and coauthors report the results of analyses of individual patient data from nine published randomized trials of MBCT. The analyses included 1,258 patients with available data on relapse and examined the efficacy of MBCT compared with usual care and other active treatments, including antidepressants.
The authors report MBCT was associated with reduced risk of depressive relapse/recurrence over 60 weeks compared with those who did not receive MBCT. There also appears to be no differing effects for patients based on their sex, age, education or relationship status.
The treatment effect of MBCT on the risk of depressive relapse/recurrence also may be larger in patients with higher levels of depression symptoms at baseline compared with non-MBCT treatments, according to the results. The authors suggest this means that MBCT may be especially helpful to those patients who still have significant depressive symptoms.
“We recommend that future trials consider an active control group, use comparable primary and secondary outcomes, use longer follow-ups, report treatment fidelity, collect key background variables (e.g., race/ethnicity and employment), take care to ensure generalizability, conduct cost-effectiveness analyses, put in place ethical and data management procedures that enable data sharing, consider mechanisms of action, and systematically record and report adverse events,” the authors conclude.
“Mindfulness practices were not originally developed as therapeutic treatments. They emerged originally in contemplative traditions for the purposes of cultivating well-being and virtue. The questions of whether and how they might be helpful in alleviating symptoms of depression and other related psychopathologies are quite new, and the evidence base is in its embryonic stage. To my knowledge, the article by Kuyken et al is the most comprehensive meta-analysis to date to provide evidence for the effectiveness of MBCT in the prevention of depressive relapse. However, the article also raises many questions, and the limited nature of the extant evidence underscores the critical need for additional research,” writes Richard J. Davidson, Ph.D., of the University of Wisconsin-Madison in a related editorial.

The key here, in my view, is that the researchers and therapists are psychologists, ie properly trained and competent.
