Trauma and Cumulative Adversity in Women of a Disadvantaged Social Location.

This study expands conceptual and empirical perspectives on stress exposure by evaluating cumulative exposure in 79 drug-convicted women. Logistic regression determined that (a) posttraumatic stress disorder (PTSD) increased 40% with each trauma and (b) adding chronic stressors increased the predictability of PTSD. This study supports cumulative adversity models and the importance of social location.
