DEFINITION
DISINHIBITED SOCIAL ENGAGEMENT DISORDER (DSED) is a developmental attachment disorder characterized by a persistent pattern of culturally inappropriate, overly familiar, and indiscriminately social behavior toward unfamiliar adults, accompanied by diminished social caution, impaired attachment discrimination, and reduced awareness of interpersonal boundaries.
The disorder develops following severe social neglect, repeated caregiver changes, institutional deprivation, disrupted attachment opportunities, or other forms of insufficient caregiving during critical developmental periods.
Within the SCF-RDOS framework, Disinhibited Social Engagement Disorder is conceptualized as a developmental attachment-regulation disorder involving dysfunction across attachment-security systems, social-boundary architecture, threat-assessment networks, developmental social-learning pathways, emotional-security mechanisms, and relational discrimination processes.
ETIOPATHOGENIC CORE
Primary Pathogenic Theme
Early deprivation of stable attachment relationships disrupts normal attachment formation and social-boundary development, resulting in indiscriminate social engagement and impaired recognition of relational safety distinctions.
Core Pathogenic Drivers
Domain | Contribution |
Severe Social Neglect | Attachment deprivation |
Institutional Care Exposure | Reduced selective attachment formation |
Repeated Caregiver Changes | Attachment instability |
Emotional Deprivation | Social-boundary dysregulation |
Developmental Attachment Failure | Indiscriminate sociability |
Early Relational Insecurity | Reduced stranger caution |
Social Learning Disruption | Boundary-development impairment |
Neurodevelopmental Adaptation | Persistent attachment abnormalities |
