The International Society for the Study of Trauma and Dissociation is an international, non-profit, professional association organized to develop and promote comprehensive, clinically effective and empirically based resources and responses to trauma and dissociation and to address its relevance to other theoretical constructs.
Although we are primarily a professionally oriented society, we welcome both professional and lay members. Check out the different categories of membership.

Education is one of our primary goals. We work to achieve that goal partly through training programs, conferences and the Journal of Trauma & Dissociation. The ISSTD has given awards to professionals and lay people who have contributed to the study of trauma and dissociation and to the ISSTD. To facilitate the education and training of graduate students, the David Caul Graduate Research Grants were established in memory of David Caul, an esteemed and devoted mentor.
