The present review examines how resources have been used in trauma-focused psychotherapy with an emphasis on their use in eye movement desensitization and reprocessing (EMDR). Current practices of EMDR-trained clinicians are presented in a historical context and considering a range of contemporary approaches to ego strengthening. This article describes the use of resources as presented in the EMDR literature along with research findings. The review concludes with a call for controlled research on widely used resource-focused procedures and practice guidelines for their use in clinical applications of EMDR.
