Clinical research on behavioral activation as treatment for post‐traumatic stress disorder: A brief review and meta‐analysis
BA gives a 26 percent PTSD symptom dip but the pooled effect is weak, so measure your own results if you use it.
01Research in Context
What this study did
Flint et al. (2020) pooled seven small trials that used behavioral activation to treat PTSD. They looked at symptom scores before and after the BA package. The team wanted to know if BA alone is enough to shrink PTSD.
What they found
Across the seven studies, PTSD symptoms dropped about 26 percent on average. Yet when the numbers were merged, the overall effect was not significant. In plain words, the drop looks nice but could still be chance.
How this fits with other research
Koskentausta et al. (2007) argued that PTSD care should target the exact mechanisms that keep symptoms alive. BA tries to do this by boosting rewarding activities, so the new data test that old idea.
Torchalla et al. (2018) showed trauma-focused CBT and EMDR give clear, medium-size relief for work-related PTSD. Flint’s 26 percent drop is smaller and not significant, so BA may lag behind those front-line choices.
Storm (1990) warned that trauma survivors need solid, tested behavioral plans. Flint’s mixed result keeps that warning alive: we still lack strong proof that BA alone is enough for PTSD.
Why it matters
If you are helping a client with PTSD, think of BA as a possible add-on, not the main dish. Track symptoms session-by-session so you can spot real change fast. If gains stall, pivot to an evidence-based trauma treatment like CBT or EMDR.

03Original abstract
AbstractBehavioral activation (BA), an effective treatment for depression, has recently been receiving attention as a possible intervention for PTSD. BA interventions could be particularly useful in treating underserved populations (i.e., individuals with lower socioeconomic status). A literature search was conducted, which identified seven outcome studies that examined the effectiveness of stand‐alone BA treatment for individuals with PTSD. All studies identified for this brief review demonstrated clinically significant reductions in PTSD symptoms using BA as an intervention. A meta‐analysis of these few studies revealed a nonsignificant effect (Cohen's d = 0.713, p = .512) despite reporting an average symptom reduction of 25.8%. Other studies utilizing BA treatment for PTSD do so in tandem with other interventions and were excluded from analysis. This brief review summarizes the literature on the use of BA as a stand‐alone treatment for PTSD and suggests that future research seek to confirm the usefulness of BA as a potential treatment modality for mental health‐care providers treating individuals with PTSD.
