Because resources are often scarce in the aftermath of disasters, a useful mental health intervention is one that is effective, feasible, rapidly available, and efficiently delivered to the largest proportion of affected individuals possible. In terms of treating PTSD in other trauma contexts, there is considerable evidence that cognitive-behavioral therapy (CBT) procedures are effective at reducing the array of PTSD symptoms. Overall, the available evidence points to the theoretical and empirical justification for using Prolonged Exposure (PE) and Stress Inoculation Training (SIT), two components of CBT, with patients presenting with PTSD. A practical limitation of available studies is that they are limited to individually administered therapy contexts that typically require between 8 and 12 sessions delivered in a specialty mental health care-setting. The labor-intensive nature of these therapies represents a significant obstacle to provision of therapy to potentially thousands of individuals suffering PTSD in the context of mass violence events.
