Traumatic events adversely affect many people during their lifetime, and the primary focus of support services is on helping the individual, group, or community to recover from the experience. This chapter provides an overview of psychological injury including the constructs of compassion fatigue (CF), vicarious trauma (VT), and burnout. The causal factors involved in developing these injuries are examined with an emphasis on the raised risks for eye movement desensitization and reprocessing (EMDR) practitioners. Compassion stress is the natural outcome that can result from knowing about trauma experienced by a client, friend, or family member. Secondary Traumatic Stress Disorder (STSD) is synonymous with CF and described as “the natural consequent behaviors and emotion resulting from knowing about a traumatizing event experienced by a significant other-the stress results from helping or wanting to help a traumatized or suffering person”.
