International Society for Study of Trauma and Dissociation seeks to advance clinical, scientific, and societal understanding about the prevalence and consequences of chronic trauma and dissociation.

The ISSTD is a nonprofit professional association organized for the purposes of information-sharing and international networking for clinicians, educators, researchers and theorists; providing professional and public education; promoting research and theory about dissociation, both normal and pathological; and promoting research and training in the identification, treatment, and prevention of complex post traumatic disorders, particularly the dissociation disorders.

ISSTD holds annual conferences around the country and is a great learning resource for therapists studying dissociation and its effects on our clients.
