Obsessive-Compulsive Personality Disorder

Medically reviewed · Ratel Health editorial team · Sunday, 16 August 2026

A personality disorder marked by a pervasive pattern of preoccupation with orderliness, perfectionism, and control, at the expense of flexibility and efficiency.

Overview

Obsessive-compulsive personality disorder involves a long-standing pattern of preoccupation with orderliness, perfectionism, and mental and interpersonal control, at the expense of flexibility, openness, and efficiency, typically beginning by early adulthood.

Signs and Symptoms

Signs can include excessive devotion to work and productivity, rigid adherence to rules, reluctance to delegate tasks, and difficulty discarding worthless objects. Experiencing one or more of these symptoms does not necessarily mean that a person has this condition. Diagnosis requires an appropriate clinical evaluation.

Causes and Risk Factors

The exact cause is not fully understood. Genetic factors and temperament, along with certain early developmental experiences, are associated with risk.

Diagnosis

A diagnosis should be made by a qualified healthcare professional following a comprehensive clinical assessment. Clinicians may use established diagnostic frameworks such as DSM-5-TR and/or ICD-11 as part of a comprehensive assessment.

Treatment

Treatment depends on the individual’s symptoms, clinical history, severity, age, co-occurring conditions, and other relevant factors.

Psychotherapy

Psychotherapy focused on flexibility and tolerating imperfection can help improve interpersonal and occupational functioning.

Living With Obsessive-Compulsive Personality Disorder

Practicing structured flexibility exercises learned in therapy can reduce rigid, perfectionistic patterns.

When to Seek Professional Help

Professional evaluation may be appropriate if symptoms persist, worsen, cause significant distress, or interfere with work, school, or relationships.

Emergency Situations

If a person may be in immediate danger, is experiencing a medical or psychiatric emergency, or may harm themselves or another person, seek immediate assistance through appropriate local emergency services.

Outlook

Many individuals see improved relationships and reduced distress with sustained psychotherapy.
