The use and reliability of psychiatric diagnosis in forensic settings

The clinical professional encounters conflict whenever he or she enters the courtroom. The psychiatrist's approach must not be simply diagnostic or simply legal. We cannot shed our clinical identity; indeed, the court depends on our clinical identity and expertise in its search for the truth. The psychiatric expert must be able to translate his or her findings for the court, but these findings must come from clinical experience, not some solely legal perspective. The legal system needs our knowledge about the interfaces of mental illness, function, and behavior. After we provide our opinions, however, the legal issues must be left to the lawyers and the final determinations left to the judge or jury.
