NOCDA: The Netherlands OCD association Study: Identifying risk factors for chronicity in the course of obessive compulsive disorder

Background

Starting date: 01/01/2008

OCD is a debilitating anxiety disorder, which was listed as the 10th most disabling medical disorder in the WHO burden of disease study. Although once considered rare, recent estimates indicate that OCD has a lifetime prevalence rate of approximately 2% worldwide.

OCD is characterized by recurrent intrusive and anxiety-provoking thoughts or images and repetitive compulsive behaviours. The disorder tends to interfere with the ability to work and the ability to form healthy relationships with others. In half of the patients, the disorder runs a chronic course despite adequate treatment. Determining factors of this unfavourable outcome remain unknown.

The NOCDA study includes 400 OCD patients in a multi-centre prospective study, in order to determine psychological and social determinants of chronicity in a large and representative clinical sample. Data on the treatment received and other use of health care services in between measurements will be carefully monitored. The knowledge provided by this study will contribute to improvements in the adequate treatment of OCD and the development of preventive strategies for a chronic outcome.
