EXCORIATION DISORDER

SCF-RDOS INDICATION REGISTRY ENTRY

Classification

DEFINITION

EXCORIATION DISORDER is a body-focused repetitive behavior characterized by recurrent, compulsive, and difficult-to-control picking of one’s own skin resulting in tissue damage, lesions, scarring, bleeding, infection risk, and significant psychological distress or functional impairment.

The behavior often occurs in response to emotional tension, anxiety, boredom, perceived skin imperfections, sensory urges, stress, or automatic habitual processes. Individuals typically make repeated attempts to reduce or stop the behavior but experience persistent recurrence.

Within the SCF-RDOS framework, Excoriation Disorder is conceptualized as a compulsive self-grooming and body-focused repetitive behavior disorder involving dysfunction across impulse-control systems, habit-formation networks, sensory-processing architecture, emotional-regulation pathways, reward-learning mechanisms, and compulsive behavior circuits.

ETIOPATHOGENIC CORE

Primary Pathogenic Theme

Abnormal interaction between sensory urges, emotional dysregulation, compulsive grooming behaviors, and maladaptive reward reinforcement produces repetitive skin-picking behaviors that become self-perpetuating and difficult to control.
