The Defense Style Questionnaire.

The Defense Style Questionnaire has proven of interest as the first questionnaire to reliably describe defense styles. The 72-item DSM-III-R-labeled Defense Style Questionnaire was administered to 388 controls and 324 patients. Eight statistical and two a priori criteria were used in choosing two items to represent each of the 20 defenses. A new 40-item Defense Style Questionnaire is published together with normative and reliability data on a normal population, patients with anxiety disorders, and child-abusing parents. The scores are unaffected by the sex of the respondent, but the endorsement of immature defense styles decreases with age.
