Obsessive-compulsive personality disorder (OCPD) is a chronic condition in which a person demonstrates an excessive focus on details, order and rules, and the need to achieve a perfect outcome, often in a way that interferes with daily life. They can be stubborn, insisting that things must be done their way. The desire for order, perfection, productivity, and control can impede their ability to finish tasks, to collaborate with other people, and to treat social activities or hobbies as purely recreational. In addition to demanding that others follow certain rules or meet high standards, people with OCPD can be severely self-critical.
OCPD is one of the most common personality disorders, according to the DSM-5; prevalence estimates range from 2.1 to 7.9 percent. OCPD is classified as a "Cluster C" personality disorder, as are avoidant personality disorder and dependent personality disorder. Anxiety and fear are the features shared by each of these disorders.
OCPD is distinct from obsessive-compulsive disorder (OCD). While the disorders share features such as a strong preoccupation with details and rules in some area of one's life, they differ in important ways. People with OCPD do not have unwanted thoughts that compel them to create routines or rituals, as do those with OCD. In contrast, people with OCPD experience their thoughts and behavior as rational and purposeful. Their symptoms are stable across time, whereas symptoms of OCD often change over time and in response to anxiety-provoking circumstances.
