Complex PTSD is on the trauma spectrum: comment on Resick et al. (2012).

Conceptualizing posttraumatic stress disorder (PTSD) along a spectrum with complex and simple features is integrative and models an approach taken by disciplines in medicine outside of psychiatry. This perspective is offered in the Resick et al. (2012) review. To best delineate the nature and permeability of the border between Complex PTSD and PTSD, an emphasis on clarifying underlying biological processes is needed to move beyond our current reliance on symptomatic description.
