According to Dr. Christine Courtois (n.d.), CPTSD is a form of Complex Trauma that often develops when traumatic events/experiences:

  • are repetitive, prolonged, or cumulative;

  • are most often interpersonal, involving direct harm, exploitation, and maltreatment including neglect/abandonment/antipathy by primary caregivers or other ostensibly responsible adults; and

  • occur at developmentally vulnerable times in the victim's life, especially in early childhood or adolescence, but can also occur later in life and in conditions of vulnerability associated with disability, disempowerment, dependency, age, infirmity, etc.

Although there are a number of types of Complex Trauma (e.g., natural disasters, community or group trauma such as racism), the focus here at OOTS is on relational trauma including neglect and all forms of ongoing emotional, physical, and sexual abuse.
