Complex PTSD is different from PTSD due to the involvement in a chronic long-term event where there was a sense of captivity without the ability to easily escape.  This could involve a child or an adult being physically or emotionally held captive and being powerless against the abuser.  For instance, a child might experience long term sexual and/or physical abuse by a parent, family member or caregiver and/or “held hostage” to witness ongoing physical abuse or sexual violence in the home.  A child or an adult that has been abducted, taken hostage or involved in human trafficking may have other psychological symptoms such as dissociation or attachment issues in addition to the standard symptoms of PTSD.
