Question to the Department of Health and Social Care:

To ask the Secretary of State for Health, what estimate his Department has made of the number of people in the UK with a diagnosis of obsessive compulsive disorder in each of the last five years.

The Department does not hold data on an annual basis of the numbers of people with a diagnosis of obsessive compulsive disorder. The Department has commissioned the National Centre for Social Research and the University of Leicester to undertake the 2014 Adult Psychiatric Morbidity Survey.

The Adult Psychiatric Morbidity Survey in 2007 found that 1.3% of people aged 16-64 living in England reported that they had obsessive compulsive disorder.
