A systematic meta-review of 18 meta-analyses (up to 2572 participants) examined mindfulness- and acceptance-based interventions for people with schizophrenia spectrum disorders. At the end of treatment, significant small-to-large effects were found for overall symptoms, positive symptoms, negative symptoms, affective symptoms, social functioning, mindfulness, and acceptance. For example, 100% of mindfulness-based intervention meta-analyses reported significant improvement in overall symptoms (effect size g = -0.7), while 25% of acceptance-based intervention meta-analyses did. All meta-analyses were rated low or critically low in quality. The largest effects came from studies with mostly Chinese samples. The authors conclude that these interventions show promise but caution that methodological limitations and cultural factors need further study.
