Findings
PTSD
REMISSION
In this randomized clinical trial involving 234 military personnel and veterans treated with massed or intensive outpatient formats of prolonged exposure therapy, 61% achieved clinically significant reductions in clinician-assessed PTSD symptoms and 74% had self-reported PTSD symptom reductions at the 1-month follow-up assessment. There were no significant differences between the treatment groups, and in both, more than 50% of participants maintained PTSD diagnostic remission at the 6-month follow-up.
