Complex PTSD includes the symptoms of PTSD plus a range of disturbances of self-regulation (e.g., in emotion, relationships, belief systems, dissociation, somatic distress) as a result of prolonged or repeated or multiple forms of interpersonal trauma (e.g., childhood physical and sexual abuse, domestic violence, sex trafficking, experiencing torture, exposure to genocide, etc.).
In 2012, the ISTSS Expert Consensus Treatment Guidelines for complex PTSD in Adults recommended that the treatment "be patient-centered" and with three stages/phases of treatment. (Please see the attached PDF). I am very interested to know if there are any new developments in the research and clinical practice in this area. Any empirical studies and/or practice-based evidences would be appreciated.
