A new language for psychoanalytic diagnosis.

Many psychoanalysts believe it is impossible to conduct empirical research without eviscerating or trivializing psychoanalytic constructs, and past research efforts have all too often reinforced this view. A new method for studying personality and personality pathology is presented that challenges such beliefs. This method, the Shedler-Westen Assessment Procedure (SWAP), captures the richness and complexity of psychoanalytic constructs and formulations while also providing reliable data for research. The method is being used to develop a new personality disorder taxonomy, as an alternative to the DSM, that is both empirically grounded and psychoanalytically relevant. Its role in psychoanalytic training and supervision is discussed, as is its value as a measure of structural change in psychoanalytic process and outcome research.
