Metacognitive therapy (MCT) is a psychological "talking therapy" for the treatment of mental disorders. It was created by Adrian Wells based on an information processing model by Wells and Matthews. It is supported by scientific evidence from a large number of studies. The goals of MCT are first to discover what patients believe about their own thoughts and about how their mind works (called metacognitive beliefs), then to show the patient how these beliefs lead to unhelpful responses to thoughts that serve to unintentionally prolong or worsen symptoms, and finally to provide alternative ways of responding to thoughts in order to allow a reduction of symptoms. In clinical practice, MCT is most commonly used for treating anxiety disorders such as social anxiety disorder, generalised anxiety disorder (GAD), health anxiety, obsessive compulsive disorder (OCD) and post-traumatic stress disorder (PTSD) as well as depression – though the model was designed to be transdiagnostic (meaning it focuses on common psychological factors thought to maintain all psychological disorders).
Metacognition, Greek for "after" (meta) "thought" (cognition), refers to the human capacity to be aware of and control one's own thoughts and internal mental processes. Metacognition has been studied for several decades by researchers, originally as part of developmental psychology and neuropsychology. Examples of metacognition include a person knowing what thoughts are currently in their mind and knowing where the focus of their attention is, and a person's beliefs about their own thoughts (which may or may not be accurate).
Model of mental disorders
In the metacognitive model, symptoms are caused by a set of psychological processes called the cognitive attentional syndrome (CAS). The CAS includes three main processes, each of which constitutes extended thinking in response to negative thoughts. These three processes are:
All three are controlled by patients' metacognitive beliefs, such as the belief that these processes will help to solve their problems (although the processes all ultimately have the unintentional consequence of prolonging distress).
MCT is a time-limited therapy which usually takes place between 8–12 sessions. The therapist uses discussions with the patient to discover their metacognitive beliefs, experiences and strategies. The therapist then shares the model with the patient, pointing out how their particular symptoms are caused and maintained.
Therapy then proceeds with the introduction of techniques tailored to the patient's difficulties aimed at changing how the patient relates to thoughts and that bring extended thinking under control. Experiments are used to challenge metacognitive beliefs (e.g. "You believe that if you worry too much you will go 'mad' – let's try worrying as much as possible for the next 5 minutes and see if there is any effect") and strategies such as attentional training technique and detached mindfulness (this is a distinct strategy from various other mindfulness techniques).
Clinical trials (including randomized controlled trials) have found MCT to produce large clinically significant improvements across a range of mental health disorders, although as of 2014 the total number of subjects studied is small and a meta-analysis concluded that further study is needed before strong conclusions can be drawn regarding effectiveness. A special issue of the journal Cognitive Therapy and Research was devoted to MCT research findings.
