disturbances in self-organization (dso)

Disturbances in Self-Organization (DSO) are a cluster of symptoms that distinguish Complex PTSD (C-PTSD) from classic PTSD in the ICD-11 framework. They capture the deeper identity and relational wounds that follow prolonged, inescapable trauma—often beginning in childhood.

DSO has three core domains: affective dysregulation (difficulty managing emotions, swinging between numbness and overwhelm), negative self-concept (persistent shame, worthlessness, or defectiveness), and disturbed relationships (fear of closeness, mistrust, feeling different or disconnected from others). These features often persist long after the original danger has passed and shape daily life in ways that fear-based PTSD symptoms alone cannot explain. Clinically, recognizing DSO guides phase-based trauma work and validates survivors whose struggle has been primarily about self and connection.
