Current research and clinical observations suggest pronounced gender-based differences in the ways people respond to traumatic events. Most notably, women evidence twice the rate of PTSD as men following traumatic exposure. This important volume brings together leading clinical scientists to analyze the current state of knowledge on gender and PTSD. Cogent findings are presented on gender-based differences and influences in such areas as trauma exposure, risk factors, cognitive and physiological processes, comorbidity, and treatment response. Going beyond simply cataloging gender-related data, the book explores how the research can guide us in developing more effective clinical services for both women and men. Incorporating cognitive, biological, physiological, and sociocultural perspectives, this is an essential sourcebook and text.
