A recently published meta-analysis by independent researchers at the Universities of Copenhagen and Amsterdam examined the effectiveness of metacognitive therapy (MCT) for anxiety and depression. In a paper published in the journal: Anxiety and Depression, data was analysed from 16 studies of which 9 were controlled trials. The authors report large effects from pre to post treatment and demonstrated that MCT was more effective than waitlist control groups and more effective than cognitive-behaviour therapy. This is an exciting finding but we need to be cautious in forming conclusions at this stage, more studies are required that compare MCT with other evidence-based treatments.
