The International Society for the Study of Trauma and Dissociation (ISSTD) is the only international nonprofit professional society that promotes research and training in the identification and treatment of dissociative disorders and their relationship to developmental, relational, and other traumas.

ISSTD provides a single source for professional and public education and supports international communication and cooperation among professional clinicians and investigators working in the fields of dissociation and trauma.

To tackle the issues involved in research about and treatment of dissociative disorders, individual commitment and passion are necessary. But they are not enough. We need outstanding, ongoing professional education and information. And we need each other. Together, we can and do make a difference!
