The Shedler-Westen Assessment Procedure (SWAP-200) is a psychological test for personality diagnosis and clinical case formulation, developed by psychologists Jonathan Shedler and Drew Westen. SWAP-200 is completed by a mental health professional based on their observations and knowledge of a patient, client, or assessment subject. The person being assessed does not interact with the test. Because SWAP-200 is completed by the clinician, diagnostic findings do not depend on the accuracy of information people disclose about themselves and test results can not be faked. The SWAP instruments are based on over two decades of empirical research described in more than 100 articles in peer-reviewed scientific journals. SWAP-200 has been translated into fifteen languages. Other SWAP instruments include the revised SWAP-II and the SWAP-II-A for adolescents.

SWAP-200 is used by clinical practitioners to identify core psychological issues to address in psychotherapy, for personality disorder diagnosis, by forensic examiners, and by agencies of the United States federal government for assessment of personnel for sensitive positions such as those requiring high-level security clearances.
