Five stages of grief
The five stages of grief model (or the Kübler-Ross model) postulates that those experiencing grief go through a series of five emotions: denial, anger, bargaining, depression, and acceptance. Although commonly referenced in popular culture, studies have not empirically demonstrated the existence of these stages, and some consider to be out dated. The model was introduced by Swiss-American psychiatrist Elisabeth Kübler-Ross in her 1969 book On Death and Dying, and was inspired by her work with terminally ill patients. Motivated by the lack of instruction in medical schools on the subject of death and dying, Kübler-Ross examined death and those faced with it at the University of Chicago's medical school. Kübler-Ross's project evolved into a series of seminars which, along with patient interviews and previous research, became the foundation for her book. Although Kübler-Ross is commonly credited with creating stage models, earlier bereavement theorists and clinicians such as Erich Lindemann, Collin Murray Parkes, and John Bowlby used similar models of stages of phases as early as the 1940s.Later in her life, Kübler-Ross noted that the stages are not a linear and predictable progression...
