With a new generation of American combat veterans returning from Iraq, the nation has an obligation to do everything possible to improve care for posttraumatic stress disorder (PTSD). Although art therapy has been understudied in this context, it shows promise as a means of treating hard-to-treat symptoms of combat-related PTSD, such as avoidance and emotional numbing, while also addressing the underlying psychological situation that gives rise to these symptoms. In this paper, we establish a conceptual foundation for research about art therapy as a treatment for combat-related PTSD by situating art therapy within the context of other PTSD treatments, outlining a theoretical rationale for using art therapy as a treatment for PTSD, and clarifying "best practices" for using art therapy as a treatment for combat-related PTSD. We recommend group treatment in three stages and suggest that art therapists who treat combat-related PTSD receive specialized training in trauma intervention and PTSD theory.
