David Veale, Contamination fears in OCD: About

Treating contamination fears in OCD

On Demand - £40 in our NEW YEAR SALE


Contamination is one of the most common fears in OCD. About 1/3rd of people with OCD will have co-morbid depression. A common process in contamination is that of ‘contagion’ or transfer. It can include mental contamination where the source is usually inside the body or all-over dirtiness or polluting thoughts about sex, violence, or blasphemy. Contamination is associated with avoidance behaviour, compulsive washing, checking and mental rituals. The motivation to prevent contamination may be to prevent harm, losing control or to avoid feelings of disgust.

Newer developments In CBT include the role of inhibitory learning in exposure and how this overlap with behavioural experiments and understanding of the problem by testing Theory A / Theory B. Exposure in contamination includes transfer of the “contaminants” and spoiling of compulsions such as washing.  Special consideration in therapy is required for intrusive sexual and violent images. Newer treatment interventions include imagery rescripting for aversive memories and concurrent treatment for depression (for example improving sleep, diet, exercise, social activity and reducing shame).

  5. Conduct a real risk assessment for polluting thoughts

  6. Understand the role of inhibitory learning in exposure and the overlap with behavioural experiments

  7. Conduct exposure and response prevention, behavioural experiments, drop safety seeking behaviours and do “anti-OCD” tasks.

The OCD 'Bully'

People with OCD often consider their OCD to be like a bully or a demon that has to be obeyed. During the process of cognitive behaviour therapy, they may be encouraged to “externalise” their bully and to act against it by doing the opposite to what the bully demands. Clinicians at the Institute of Psychiatry decided to make  a humanoid version of an OCD bully or monster. On the outside of the bully are various manifestations of OCD – for example a clock that represents the wasted time of compulsions; a toilet seat that is full of “germs”; knives for fears of being violent; words such as “Paedophile” and numbers such as “666”. The bully has several eyes to depict the vigilance for threat. A door in its chest opens to reveal a heart of stone. At the base is a broken mirror.

The Bully was featured in the British Medical Journal (BMJ 2010; 341: c2596).

It was unveiled by Professor Jack Rachman on 9th March 2010. Professor Rachman  is a leading authority on OCD and used to work on the unit in the 1980s. It is now on permanent loan to the Anxiety Disorders Residential Unit at the Bethlem Royal Hospital from David Veale, who commissioned the piece from his friend Steve Caplin.
