Identity has been a part of psychiatry from its roots. Sigmund Freud’s description of the id, ego, and super ego reflects the various identities that lie within each of us. Carl Jung introduced the development of our identity through the stages of life. We have identity disorders in the DSM. In psychiatry, we diagnose patients, and that diagnosis can meaningfully impact identity formation. It plays a part in the way persons views themselves while also influencing how they are perceived by others. The discussion of identity development through our experiences and how we view our current identity plays an integral role in therapy. This month’s Book Forum focuses on 3 books that look at identity through various lenses of experience, diagnosis, and treatment. Although they provide just a snapshot, it is clear from these reviews the significant impact that these books made on the reader.
