People who are the most likely to be traumatized and to develop PTSD are often the least likely to receive treatment. These special populations often have limited social support and resources and face multiple life challenges. These factors, along with vulnerability to stress, make it difficult for mental health professionals to engage them in conventional treatment programs for PTSD. This accessible volume includes everything needed to implement a program, including session-by-session instructions, sample dialogues to demonstrate techniques, and user-friendly handouts and worksheets. This volume is suitable for people in the clinical or counseling psychology field, including individuals in private practice. It is intended for clinicians who provide psychiatric rehabilitation or addiction treatment services, those who work in schools or primary care clinics, and care providers whose work is defined by the needs of special populations such as cultural minorities, refugees, homeless people, or the urban poor.
