Seven RCTs were included in the review (n=209). Sample sizes ranged from 14 to 39 participants.
The overall mean effect size for the effect of eye movement desensitization and reprocessing on post-test trauma status was medium and significant (d=0.56, 95% CI 0.42 to 0.70; seven studies). This result was found to be significantly heterogeneous (p<0.001), although there was no evidence of publication bias (fail-safe number=145).
Sensitivity analyses indicated effect sizes were lower in more recent studies and in trials with more completers. Studies that used fewer sessions or used both parent and children reporting (rather than children alone) were associated with larger effect sizes.
Further results (including exploration of the influence of other variables) were reported.
