What is metacognitive therapy and how does it treat anxiety, depression, and rumination?
How changing beliefs about thinking — not the thoughts themselves — resolves anxiety and depression
Metacognitive therapy (MCT), developed by Adrian Wells, targets not the content of negative thoughts but the beliefs people hold about thinking itself — particularly the beliefs that worry and rumination are useful or uncontrollable. By changing these meta-level beliefs, MCT aims to stop the prolonged self-focused thinking styles that maintain anxiety and depression. A growing body of randomized controlled trials supports MCT as effective for GAD, PTSD, depression, and social anxiety, with some studies showing superiority to CBT.
Most cognitive therapies target what you think about. Metacognitive therapy targets what you think about thinking. Wells observed that most psychological distress is not caused by negative events but by the extended cognitive processing — the worry, rumination, and threat monitoring — that follows them. That extended processing is driven by beliefs about thinking: "worrying helps me prepare," "I can’t control my thoughts," "if I ruminate long enough I’ll find an answer." MCT dismantles those beliefs rather than arguing about the thought content they produce.
The practices (7)
Worry and rumination are maintained by positive meta-beliefs (beliefs that the thinking style is useful: "worrying keeps me prepared") and negative meta-beliefs (beliefs that it is uncontrollable or dangerous: "I can’t stop worrying," "my worry will make me ill"). These beliefs are the levers that sustain the thinking style; addressing them is more efficient than addressing the content of any individual worry.
- 1After a prolonged worry or rumination episode, ask: "What was I implicitly believing about why it was worth thinking about this?"
- 2Probe for positive meta-beliefs: "Do I believe worrying helps me cope, prepare, or solve problems?"
- 3Probe for negative meta-beliefs: "Do I believe worry is uncontrollable, or that it will harm me?"
- 4Write down the specific belief, not just a label.
Positive and negative meta-beliefs about worry (measured by the Meta-Cognitions Questionnaire) consistently predict GAD severity and other anxiety and depression measures across many observational studies.
Honest caveat: The correlational evidence is robust; the causal claim (changing meta-beliefs resolves the disorder) is supported by RCTs but the mechanism pathway has not been directly isolated.
