no prior history of psychiatric or substance use disorders from those with a prior history who were previously in remission at the time of the 9/11 attack. This is particularly relevant given the strong relationship between childhood maltreatment and psychopathology (Keyes et al., 2012) and should be formally explored in future research. These limitations are counterbalanced by several study strengths. The NESARC is the largest psychiatric epidemiological survey of the US general population conducted to date, with rich measures of childhood maltreatment, exposure to traumatic life events, and a wide range of psychiatric disorders. Our results build on the stress-sensitization literature by providing a unique insight into the relationship between childhood maltreatment, adult exposure to 9/11, and the structure of common psychiatric disorders.
