This presentation explores the complex nature of grief, examining various theories and models that attempt to explain the grieving process. It delves into the Kubler-Ross model, outlining its five stages of grief: denial, anger, bargaining, depression, and acceptance. The presentation also introduces the seven mediators of grief proposed by J.W. Worden, which provide a framework for understanding the factors that influence an individual's grieving experience. These mediators include the relationship with the deceased, the nature of the death, and the individual's personal history and support system. By understanding these theories and mediators, we can gain valuable insights into the grieving process and develop more effective strategies for supporting individuals facing loss.
