The EMDR Integrative Group Treatment protocol (EMDR-IGTP) has been used in different parts of the world since 1998 with both adults and children after natural or man-made disasters. This protocol combines the eight standard EMDR treatment phases with a group therapy model, thus providing more extensive reach than the individual application of EMDR. In this study the EMDR-IGTP was used with 16 bereaved children after a human provoked disaster in the Mexican State of Coahuila in 2006. Results showed a significant decrease in scores on the Child’s Reaction to Traumatic Events Scale that was maintained at 3-month follow-up. Although controlled research is needed to establish the efficacy of this intervention, preliminary results suggest that EMDR-IGTP may be an effective means of providing treatment to large groups of people impacted by large-scale critical incidents (e.g., human-provoked disasters, terrorism, natural disasters).
