The effectiveness of evidence-based treatments for personality disorders when comparing treatment-as-usual and bona fide treatments.

Objective: The purpose of Study 1 was to examine the relative efficacy of evidence-based treatments (EBTs) when compared to treatment-as-usual (TAU) for adults diagnosed with a personality disorder (PD). The purpose of Study 2 was to investigate the strength of the differences between bona fide psychotherapeutic treatments for PDs.

Method: Two separate computerized searches were conducted of: (a) studies that directly compared an EBT with a TAU for treatment of PDs, or (b) studies that compared at least two bona fide treatments for PDs.
