This systematic review synthesized randomized controlled trials of psychoeducation for adults with PTSD, including interventions delivered alone or as a primary component. Twenty-six trials involving 3,304 participants were included, with substantial variation in intervention format and duration. Nine trials reported significant reductions in PTSD symptoms attributable to psychoeducation: one preventive intervention and eight post-diagnosis. Every trial with significant between-group effects used digital delivery, and most included some human guidance. Overall effects were inconsistent, and the evidence was limited by methodological concerns and risk of bias.
Key findings
- Of 26 RCTs involving 3,304 adults, nine reported significant PTSD symptom reductions attributable to psychoeducation.
- The nine positive trials comprised one preventive intervention and eight interventions delivered after PTSD diagnosis.
- All trials reporting significant between-group effects used digital delivery; most also included some human guidance.
- Some trials reported improvements in perceived stress, anxiety, stigma, and help-seeking intentions.
Why it matters
Psychoeducation may offer an accessible entry point to care and support engagement, but the inconsistent findings do not establish it as sufficient treatment for PTSD. The review highlights digital delivery, often with human guidance, as a feature of trials reporting significant effects, while also underscoring the need to interpret these results cautiously given evidence-quality concerns.
What to keep in mind
Interventions varied substantially, overall effects were inconsistent, and several positive trials had some concerns or a high risk of bias. The review was not prospectively registered.
