The obsessive–compulsive spectrum is a model of medical classification where various psychiatric, neurological and/or medical conditions are described as existing on a spectrum of conditions related to obsessive–compulsive disorder (OCD). "The disorders are thought to lie on a spectrum from impulsive to compulsive where impulsivity is said to persist due to deficits in the ability to inhibit repetitive behavior with known negative consequences, while compulsivity persists as a consequence of deficits in recognizing completion of tasks." OCD is a mental disorder characterized by obsessions and/or compulsions. An obsession is defined as "a recurring thought, image, or urge that the individual cannot control". Compulsion can be described as a "ritualistic behavior that the person feels compelled to perform". The model suggests that many conditions overlap with OCD in symptomatic profile, demographics, family history, neurobiology, comorbidity, clinical course and response to various pharmacotherapies. Conditions described as being on the spectrum are sometimes referred to as obsessive–compulsive spectrum disorders.

👉 Obsessive–compulsive spectrum in the context of Dermatillomania
Excoriation disorder, more commonly known as dermatillomania, is a mental disorder on the obsessive–compulsive spectrum that is characterized by the repeated urge or impulse to pick at one's own skin, to the extent that either psychological or physical damage is caused. The exact causes of this disorder are unclear but are believed to involve a combination of genetic, psychological, and environmental factors, including stress and underlying mental health conditions such as anxiety or obsessive-compulsive disorder (OCD). Individuals with excoriation disorder may also experience co-occurring conditions like depression or body dysmorphic disorder (BDD). Treatment typically involves cognitive behavioral therapy and may include medications. Without intervention, the disorder can lead to serious medical complications.

Obsessive–compulsive spectrum in the context of Asperger syndrome
Asperger syndrome (AS), also known as Asperger's syndrome or Asperger's, was a diagnostic label that was historically used to describe a neurodevelopmental disorder characterized by significant difficulties in social interaction and nonverbal communication, along with restricted and repetitive patterns of behavior and interests. The term was retired as a formal diagnosis when it was merged into autism spectrum disorder (ASD) in the WHO's ICD-11 and the APA's DSM-5-TR These organizations no longer recognize Asperger syndrome as a distinct clinical diagnosis. AS was considered milder than other diagnoses. This change reflected a shift toward a unified understanding of autism-related conditions rather than a judgment about individuals previously diagnosed with AS. Despite its removal from contemporary medical classification systems, many people continued to identify with the term Asperger's because of its long-standing use, personal relevance, and the way it shaped their diagnostic history and community identity.
The syndrome was named in 1976 by English psychiatrist Lorna Wing after the Austrian pediatrician Hans Asperger, who in 1944 described children in his care who struggled to form friendships, did not understand others' gestures or feelings, engaged in one-sided conversations about their favorite interests, and were clumsy. In 1990 (coming into effect in 1993), the diagnosis of Asperger syndrome was included in the tenth edition (ICD-10) of the World Health Organization's International Classification of Diseases, and in 1994 it was also included in the fourth edition (DSM-4) of the American Psychiatric Association's Diagnostic and Statistical Manual of Mental Disorders. With the publication of DSM-5 in 2013, the syndrome was removed, and the symptoms are now included within autism spectrum disorder along with classic autism and pervasive developmental disorder not otherwise specified (PDD-NOS). It was similarly merged into autism spectrum disorder in the International Classification of Diseases (ICD-11) in 2018 (published, coming into effect in 2022).
Obsessive–compulsive spectrum in the context of Body-focused repetitive behavior
Body-focused repetitive behavior (BFRB) is an umbrella name for impulse-control behaviors involving compulsively damaging one's physical appearance or causing physical injury.
BFRB disorders are currently estimated to be under the obsessive–compulsive spectrum. They are also associated with attention deficit hyperactivity disorder (ADHD) and anxiety.
Obsessive–compulsive spectrum in the context of Body dysmorphic disorder
Body dysmorphic disorder (BDD), also known in some contexts as dysmorphophobia or dysmorphia, is a mental disorder defined by an overwhelming preoccupation with a perceived flaw in one's physical appearance. In BDD's delusional variant, the flaw is imagined. When an actual visible difference exists, its importance is disproportionately magnified in the mind of the individual. Whether the physical issue is real or imagined, ruminations concerning this perceived defect become pervasive and intrusive, consuming substantial mental bandwidth for extended periods each day. This excessive preoccupation induces severe emotional distress and also disrupts daily functioning and activities. The DSM-5 places BDD within the obsessive–compulsive spectrum, distinguishing it from disorders such as anorexia nervosa.
BDD is estimated to affect from 0.7% to 2.4% of the population. It usually starts during adolescence and affects both men and women. The BDD subtype muscle dysmorphia, perceiving the body as too small, affects mostly men. In addition to thinking about it, the sufferer typically checks and compares the perceived flaw repetitively and can adopt unusual routines to avoid social contact that exposes it. Fearing the stigma of vanity, they usually hide this preoccupation. Commonly overlooked even by psychiatrists, BDD has been underdiagnosed. As the disorder severely impairs quality of life due to educational and occupational dysfunction and social isolation, those experiencing BDD tend to have high rates of suicidal thoughts and may attempt suicide.
