Mindfulness-based cognitive therapy reduced rumination scores across randomized trials
A pooled analysis found lower rumination scores and improvements in related psychological measures. Follow-up results also favored therapy, but their timing was not specified.
Based on the published abstract. The full paper may contain additional methods, results and limitations.
The 30-second takeaway
Mindfulness-based cognitive therapy showed favorable pooled results for rumination, the review's primary outcome, and for several related psychological measures. Benefits were also reported during follow-up. However, the abstract does not identify the comparison conditions or follow-up lengths, leaving uncertainty about what the therapy outperformed and how long the observed differences lasted.
The abstract does not describe participant profiles, comparison treatments or follow-up durations. Its publication-bias tests found no significant signal, but that does not establish that all relevant evidence was captured or free of bias.
The main question
Researchers centered the review on rumination scores and also assessed mindfulness, self-compassion, decentering, depression and anxiety. Improvements across these measures describe changes in psychological scores; they do not establish recovery from a particular diagnosis.
Understanding the pooled results
Effects were reported as standardized mean differences, allowing results measured on different scales to be combined. These are not percentage reductions in rumination. Without follow-up timing, the reported persistence cannot be assigned a specific duration.
