Max is a boy nearly four years of age who lived with his family in Battery Park City, across the street from the World Trade Center.
Prior to 9/11, he had already experienced numerous traumatic events including surgeries for a chronic condition and hospitalization for a minor burn.
In December 2001 Max saw his pediatrician for the first time in several months and presented with vomiting and poor appetite.
To further assess his condition, the pediatrician asked Max's mother to complete the PSC-17, a shortened version of the PSC-35 with subscales for internalizing, attention, and externalizing problems.
Max had an overall positive score on PSC-17 and a positive score for internalizing problems.
Since 9/11, Max has reverted to wearing diapers at night, wearing his shoes all the time, has become increasingly introverted and stopped wanting to go to school, although he enjoyed going to school in the past.
Over time, pediatric visits grew more frequent as Max continued to experience stomachaches and difficulty breathing despite normal physical exams.
