This study furthers the validation of the Comprehensive Assessment of Defense Style (CADS) as a measure of children's defensive behavior. Participants were 81 mothers who assessed the defense style (CADS) of their 8- to 10-year-old children, as well as their own defense style and level of object relations. Five years earlier, the mothers had rated their children's symptom level and personality after the missile attacks during the Gulf War. The original factor structure of the CADS was replicated for the most part. Self-oriented and other-oriented defenses were related to the children's early personality and symptomatic reaction, as well as to their mother's defense style and level of object relations. The CADS factors correlated with the defenses of the Defense Mechanisms Manual. The results provide further validation of the CADS and suggest possible areas of implementation, such as longitudinal examination of defenses, psychopathology screening, and therapeutic improvement.
