About

The study involves a comparing a new psychological treatment- Metacognitive Therapy (MCT) which has shown promising results in the treatment of health anxiety to no treatment at all- a waiting list.

Full description

Hypochondriasis or severe health anxiety is characterised by excessive, disproportionate and persistent thoughts, behaviour and emotion focused on physical symptoms and/or fear of developing a serious illness. There is often excessive worry about illness or disease in the absence of supporting medical evidence and contrary to continual medical reassurance.

The most effective psychological treatments are cognitive and behavioural therapies (CBT). However, CBT has failed to demonstrate consistent gains in the treatment of this disorder.

A newer form of psychological therapy, Metacognitive Therapy (MCT) has shown to be more effective than CBT in the treatment of anxiety disorders and depression. MCT is based on the principle that health anxiety is caused by a pattern of extended thinking, this pattern is called the Cognitive Attentional Syndrome (CAS). The CAS is made up of chains of verbal thought in the form of excessive worry about having an illness; a pattern of focusing attention on threat, such as scanning the body for signs of illness and excessive body checking; and coping strategies that have negative effects, such as internet searching for illnesses or trying to block out thoughts of illness. Rather than stopping negative thinking the CAS extends it and leads to the belief that illness is present. To help reduce these symptoms MCT teaches specific techniques that help people develop new ways of experiencing negative thoughts about illnesses, allow them to abandon worry and learn to disengage from unhelpful coping attempts.

A recent small study has provided some limited evidence that metacognitive therapy (MCT) can be applied to cases of hypochondriasis and demonstrated that the therapy was associated with improvement in symptoms.

To provide future evaluation of MCT in this client group a more definitive trial will be carried out to ascertain the effects of MCT in a larger group when compared to a control group.

If the results are positive this will provide a rationale for a larger research study, which will compare MCT with evidence based treatment such as CBT.
