Book excerpt: 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.
