The United States has the highest rate of incarceration in the world. According to the Bureau of Justice Statistics, 2,266,800 adults were incarcerated in U.S. federal and state prisons and county jails at year-end 2010 – about 0.7% of the resident adult population. Childhood trauma increases the likelihood of criminal justice involvement in adulthood (Wolf & Shi, 2010). A high percentage of prisoners are survivors of childhood abuse and other traumas before they are imprisoned (Wallace, Connor, & Dass-Brailsford, 2011), and prisons are notoriously violent and traumatic places for inmates. In a survey of inmates in Midwestern prisons, 54% of men and 28% of women reported having been raped in their current facility (Struckman-Johnson & Struckman-Johnson, 2000). In short, prisons are veritable warehouses of traumatized adults.
