Tailoring common treatment principles to fit individual personalities

The American Psychological Association Task Force headed by Castonguay and Beutler (2006) distilled general treatment principles common to all therapies from the empirical literature. As part of this work, Critchifield and Benjamin (2006a, 2006b) summarized principles for treatment of personality disorder. The principles are pragmatic in the sense that they are based on evidence of what works, and clinicians are encouraged to apply them in ways that fit the unique presentation and needs of a given patient. An important element of the recommended approach is that it be coherent, well-coordinated, and agreed upon by the patient. Additional principles emphasize the importance of an individual's attachment and trauma history. A complex case example is presented to illustrate one way in which emphasis on an individual's relational learning history can be used to further refine and extend wisdom inherent in the cross-cutting principles and move in the direction of an integrative treatment that is closely tailored to specific case features. A research approach is also outlined for how to test the validity of principles that prescribe differential use of technique to address diverse patient presentations.
