The role of avoidant and obsessive-compulsive personality disorder traits in matching patients with major depression to cognitive behavioral and psychodynamic therapy: A replication study.
Barber and Muenz (1996) reported that cognitive behavior therapy (CBT) was more effective than interpersonal therapy (IPT) for depressed patients with elevated levels of avoidant personality disorder, while IPT was more effective than CBT in patients with elevated levels of obsessive-compulsive personality disorder. These findings may have important clinical implications, but have not yet been replicated.



We conducted a study using data from a randomized clinical trial comparing the efficacy of CBT and short-term psychodynamic supportive psychotherapy in the outpatient treatment of depression.



We found no evidence indicating that avoidant patients may benefit more from CBT compared to short-term psychodynamic supportive therapy (SPSP).



Our results indicate that treatment effect does not depend on the level of avoidance, or obsessive-compulsiveness personality disorders further examine the influence of personality disorders on the effectiveness of CBT or psychodynamic therapy in the treatment of depression.
