Two Talk Therapies Cut PTSD Symptoms in Half for Veterans

Veterans with PTSD tried one of two structured talk therapies — one focused on gradually facing trauma memories, the other on changing unhelpful thoughts about the trauma. Both cut symptoms roughly in half. One (prolonged exposure) had a slight edge in results, but more people dropped out. The other (cognitive processing therapy) kept more people in treatment.

What the trial was testing

The trial enrolled 916 patients with ptsd. The study was sponsored by VA Office of Research and Development and tracked outcomes across the full group of patients who matched the trial's eligibility profile.

Researchers followed patients through treatment and into recovery, tracking the outcomes that mattered most for the disease being studied.

What the results showed

PTSD symptoms improved substantially in both therapy groups, with mean reductions large enough to be life-changing.

JAMA network open · 2022 · NCT01928732

These findings — that both therapies cut PTSD severity scores in half on average — were published in the JAMA network open and represent the headline result of the study.

Researchers tracked outcomes across 916 patients enrolled in the trial. The result was consistent enough across the group that the team felt confident reporting it.

What this means for patients

For patients with ptsd, this result changes the calculus on what to ask their care team about. Whether it changes day-to-day care depends on factors like disease subtype, prior treatments, and where the patient is in their care journey.

What you can do now

If you're a veteran with PTSD, both of these therapies are proven to help — they're already offered at VA clinics nationwide. Your choice might come down to what feels right: facing memories directly or working through thoughts on paper. Talk to your provider about which approach fits you best.

Eligibility for the treatments mentioned above depends on specific test results and clinical history. Bring this summary, the trial name, and your most recent labs or pathology report to your next visit.
