Ten studies with a total of 1250 participants met the inclusion criteria. Seven of these studies examined PTSD. The findings demonstrated small placebo-controlled effects of CBT on target disorder symptoms (Hedges' g = 0.24, p < 0.05) and depression (Hedges' g = 0.15, p = n.s). When examining only PTSD studies, effects were reduced (Hedges' g = 0.14, p < 0.05). Heterogeneity in most analyses was very low, and no publication bias was found. Effect sizes from placebo-controlled trials from the past 5 years appear to be smaller than those in prior meta-analyses. The findings are largely driven by research on PTSD, with few placebo-controlled trials of other anxiety-related disorders published since 2017.
