The efficacy of eye movement desensitization and reprocessing (EMDR) in children with post-traumatic stress symptoms was meta-analytically examined from the perspective of incremental efficacy. Overall post-treatment effect size for EMDR was medium and significant (d=.56). Results indicate efficacy of EMDR when effect sizes are based on comparisons between the EMDR and the non-established trauma treatment or the no-treatment control groups, and the incremental efficacy when effect sizes are based on comparisons between the EMDR and the established (CBT) trauma treatment. The discussion focuses on the future replication of EMDR findings and further research on post-traumatic stress in children.
