The Defense Style Questionnaire has proven of interest as the first qu
estionnaire 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 use
d 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 di
sorders, and child-abusing parents. The scores are unaffected by the s
ex of the respondent, but the endorsement of immature defense styles d
ecreases with age.
