Changes in ego development in the wake of September 11

In a longitudinal study using the Washington University Sentence Completion Test (WUSCT), we examined changes in ego development in response to the events of September 11, 2001. A sample of 24 individuals responded to the WUSCT in both the summer and fall of 2001, before and after the events of September 11. A significant decrease in mean ego level was found following September 11, as well as more equivocal support for an increase in variability in responses to the WUSCT.
