Patient defensive behavior and therapist addressing defense (TAD) was
studied over the course of two brief dynamic psychotherapies in twenty
-eight patients with personality disorders, primarily of the Axis II C
luster C variety. Three levels of patient defense were coded: immature
, intermediate, and mature. Results indicate a significant decrease in
the frequency of intermediate defensive behavior across psychotherapy
which is not related to patient outcome. However, there is a positive
relationship between the frequency of immature defenses in the first
quartile of treatment and outcome at termination. Further, there is a
significant correlation between patient defensive behavior and the the
rapist addressing this behavior, as well as a decrease in immature and
intermediate defenses which correlates with the frequency of the ther
apist addressing these behaviors earlier in treatment. Finally, the fr
equency of TAD is significantly correlated with patient outcome.
