Academic psychologists have moved away from psychoanalytic and psychodynamic explanations of human functioning and pathology and have instead embraced neuropsychology and cognitive science. This trend has kept many psychologists and researchers from more fully understanding some of the important phenomena they chose to investigate. One area about which psychologists can learn in the psychodynamic literature is multiple personality disorder (MPD). A thorough knowledge of the psychodynamic perspective with regards to MPD is important to all those in psychology who deal with MPD patients or who study the phenomenon. By understanding the abuse most of these patients suffered and the resulting impact this has had on their personality development, psychologists can begin to create effective and promising assessment tools and intervention programs. In this article, I review MPD and its treatment from a psychodynamic perspective in hopes that those in psychology (researchers and clinicians alike) may benefit from such a discussion and will utilize this information in their attempts to understand MPD.
