Obsessive-Compulsive Personality Disorder (commonly abbreviated as OCPD) is a personality disorder characterized by persistent preoccupation with order, perfection, and control. People with Obsessive-Compulsive Personality Disorder display several or more of the following characteristics in ways that hinder social and workplace functioning: 

- Preoccupation with details, rules, lists, order, organization, or schedules
- Perfectionism that interferes with task completion 
- Excessive devotion to work, to the exclusion of social and other leisure activities 
- Inflexibility about morality, ethics, or values 
- Inability to get rid of worn-out objects, even those without sentimental value 

Obsessive-Compulsive Personality Disorder

Obsessive-compulsive disorder (OCD) is characterized by the presence of obsessions and/or compulsions. Obsessions are defined as intrusive and unwanted thoughts, mental images, fears, sensations, or urges. Compulsions are repetitive behaviors or mental acts that an individual feels driven to perform, often in response to an obsession. These cycles of obsessions and compulsions are typically distressing, time-consuming, and can significantly disrupt a person's daily activities.

A 2019 study by Gadelkarim et al. examined the presence of Obsessive-Compulsive Personality Disorder (OCPD) and Autism Spectrum Disorder (ASD) traits among patients diagnosed with Obsessive-Compulsive Disorder (OCD). The study found that out of their sixty-seven subjects, twenty-four (35%) met the criteria for a diagnosis of OCPD in addition to OCD, and twenty-one (31.34%) met the criteria for an ASD diagnosis. The most frequently overlapping traits of OCPD and OCD included over-conscientiousness, perfectionism, preoccupation with detail, rigidity, and need for control. For those meeting the criteria for both OCPD and ASD, attention-switching, attention to detail, and social communication were all significantly impacted. Common traits in those with all three disorders included workaholism, perfectionism, preoccupation with detail, and rigidity. In conclusion, OCD, OCPD, and ASD overlap significantly and share many key traits, and understanding how they overlap may help with providing accurate diagnoses and effective treatments for those who have one or more of these disorders. 

Overlaps between OCPD, OCD, and Autism Spectrum Disorder

Obsessive‐compulsive personality disorder (OCPD) has historically been understudied. However, links between physical health outcomes and OCPD/OCPD traits have been documented.

Obsessive-compulsive disorder (OCD) is a disorder in which people have recurring, unwanted thoughts, ideas or sensations (obsessions) that raises their level of anxiety and drive them to perform certain ritual or actions (compulsions) that serves to lower their anxiety about their thoughts. The compulsive behaviors can significantly interfere with a person’s daily activities and social interactions. Some people with OCD have faced psychological distress and worse "symptoms" in the wake of the pandemic.

Sexual minorities experience unique stress in the form of external discrimination, microaggressions, internalized stigma and homophobia, social rejection, and identity discomfort and concealment. The accumulation of these identity-based stressors is believed to explain the increased incidence of OCD in this population and have an effect on the content of their obsessive thoughts and types of compulsions.

Many studies reveal conflicting information regarding the associations between traumatic experiences and OCD or hoarding symptoms. Previous studies have found a plethora of information regarding differences and similarities between the trauma experiences of those with OCD and those with hoarding symptoms. It is still unclear exactly what types of traumatic events are associated with each, if any, the association between the time a traumatic event occurred and symptom development (i.e., prior to the onset or after the onset of symptoms), and how many traumatic events these individuals with these disorders have experienced or may experience in the future. A study in 2014 sought to answer these questions.

In the context of Obsessive-Compulsive Disorder, obsessions are defined as persistent, unintentional, and unwanted thoughts that are highly intrusive, unpleasant, and cause significant distress. These are distinct from everyday worries, like concerns about job security, or occasional unwanted thoughts, such as recalling an awkward comment. Individuals with OCD typically recognize that their obsessive thoughts are irrational but experience extreme difficulty in suppressing or ignoring them.

Characteristics of Obsessions in OCD

In the context of Obsessive-Compulsive Disorder, compulsions are defined as repetitive, ritualistic actions or mental acts performed to alleviate the distress caused by obsessions or to prevent a feared outcome. These acts are not inherently pleasurable and often lack a realistic connection to the problem they are intended to address.

Characteristics of Compulsions in OCD

When obsessive-compulsive disorder is not treated, it typically becomes a chronic, long-term condition. This can lead to persistent psychological and interpersonal difficulties throughout an individual's life.

Chronicity of Untreated OCD

Body Dysmorphic Disorder (BDD) is a condition where an individual is intensely preoccupied with a perceived flaw in their physical appearance, which is often nonexistent or barely perceptible to others. This preoccupation can cause the person to believe they are unattractive, ugly, or deformed. The intense focus on these imagined defects leads to repetitive, ritualistic behaviors and mental acts. These compulsions can include constantly checking one's appearance in the mirror, attempting to conceal the perceived flaw, making comparisons to others, and in some cases, seeking cosmetic surgery.
