Introduction to <i>In Session</i> special issue: Psychotherapy for complex PTSD

Complex Posttraumatic Stress Disorder (CPTSD) is a condition resulting from exposure to chronic, interpersonal traumatic events, in which some form of control or power dynamics existed. Its clinical picture includes the main symptom clusters of posttraumatic stress disorder, accompanied by dysregulated emotion, problems in interpersonal relationships, and difficulties in identity integration. In addition, both clinical work and research have shown CPTSD to include highly distressing and complicated psychological phenomena, such as identification with the aggressor, various forms of dissociation, self-harm and self-destructive behaviors, and more. Due to this highly complex and multilayered clinical picture, the treatment of CPTSD poses a significant clinical challenge to therapists. In this special issue of In Session, we present a series of case studies, each representing a different therapeutic approach to CPTSD (e.g., skills training for affective and interpersonal regulation, Eye Movement Desensitization and Reprocessing, psychodynamic, integrative psychotherapy). These cases also represent a wide variety of patient populations, as well as different types of underlying traumatic events. Together, they reveal the breadth of clinical possibilities currently available to trauma therapists encountering cases of CPTSD. They also highlight the challenges and dilemmas that clinicians often face when treating this condition, as well as ways to overcome those.
