Type 2 or complex trauma results from multiple or repeated traumatic events occurring over extended periods. Complex trauma is often associated with other adversity and stressors such as neglect, loss or deprivation. For many individuals these traumas occur at a developmentally vulnerable time with the perpetrator often in a caregiving role. Patients who have experienced complex trauma should be assessed for the core symptoms of PTSD. In addition, patients should be assessed for disturbances in the three domains of emotional dysregulation, negative self-concept and interpersonal disturbances.
