Level A Psychotherapy Choices
Patients should be offered one of the evidence-based traumafocused psychotherapeutic interventions that include components
of exposure and/or cognitive restructuring; OR stress inoculation
training.
Choice should be based on symptom severity, clinician expertise,
and patient preference, and may include:
Exposure therapy (e.g., Prolonged Exposure)
Cognitive therapy (e.g., Cognitive Processing Therapy)
Stress management therapy (e.g., SIT) or
Eye Movement Desensitization & Reprocessing (EMDR)
VA/DoD Guideline: Therapy Selection
1. Explain the range of available and effective therapeutic options for
PTSD to all patients with PTSD
2. Patient education is recommended as an element of treatment of
PTSD for all patients and family members
3. Patient and provider preferences should drive the selection of
evidence-based psychotherapy and/or evidence-based
pharmacotherapy as 1st line treatment
4. Psychotherapies should be provided by practitioners who have been
trained in that particular method
5. A collaborative care approach to therapy administration, with care
management, may be considered

Complementary and Alternative Medicine
What is CAM?
A group of diverse medical and health care systems, practices,
and products that are not generally considered part of
conventional medical.
National Center for Complementary and Alternative Medicine
Natural Products
Herbal medicines, dietary supplements, probiotics
Mind and Body Medicine
Meditation, Acupuncture, Yoga, Progressive Relaxation
Manipulative and Body-Based Practices
Massage therapy, Spinal Manipulation
NCCAM website: nccam.nih.gov
Other ways to Organize CAM
Based on validity of proposed mechanism:
1) Consistent with current medical perspectives and
understanding of pathophysiology
2) Unsure of mechanism for perceived benefit
3) Violates basic laws of physics/chemistry/biology
Or Based on Modality Type:
1) Interventions (e.g. Acupuncture)
2) Care Delivery Method (e.g. Computer Based Therapy)
3) Personal Activities (e.g. Recreational Therapy)
Why is CAM Research so complicated?
1. Hypothesis development
Design believable studies
2. Definition and Validation of Diagnosis
Define PTSD using validated instruments
Establish Chronicity of symptoms
3. Treatment Design
Standardize the intervention
4. Measuring outcome
Use established assessment tools to evaluate
Include follow-up assessments
5. Interpreting Results
Identify primary and secondary outcome measures prior to the trial
