Posttraumatic stress disorder (PTSD) is most commonly treated
with behavioral and cognitive techniques (Deacon and Abramowitz 2004).
The National Institute for Health and Clinical Excellence (NICE;
formerly National Institute for Clinical Excellence) in the United
Kingdom has developed a set of guidelines for the treatment and
management of PTSD (National Institute for Clinical Excellence 2005).
As part of the guideline development process, they conducted a meticulous
meta-analytic review of psychological and pharmacological treatments
for PTSD. For the purposes of their review, they divided the psychotherapies
into four categories: 1) trauma-focused CBT (e.g., exposure, biofeedback-assisted
desensitization treatment, and cognitive reprocessing therapy);
2) eye movement desensitization and reprocessing, stress management,
and relaxation (stress inoculation training and progressive muscle
relaxation); 3) other therapies (supportive therapy/nondirective counseling,
psychodynamic therapies, and hypnotherapy); and 4) group CBT. All
studies included in the meta-analysis were RCTs.
