In her book, In Death and Dying (1969), Elisabeth Kubler-Ross proposed the five stages of the dying process. Though her work has often been referred to as the "five stages of grief," the original work was based on her clinical observations of the psychosocial responses of terminally ill patients to their impending death. Much scholarly debate has surrounded the legitimacy of her five "stages"—denial, anger, bargaining, depression, and acceptance. Experienced psychosocial clinicians have largely rejected the accuracy of the model because it addresses only emotional states, sets up false expectations of the process, and have not been empirically verified as a descriptive model.
