This chapter explores the evolution of modern understandings of grief, suggesting an increasing recognition of its diversity, fluidity, and sociocultural significance. Groundbreaking work, such as Freud’s concept of “Grief Work” and Kübler-Ross’s Five Stages of Grief, established a foundation for later developments. Contemporary models have transitioned from universal, linear frameworks to those that emphasize dynamic and individualized processes, including the Tasks of Mourning, the Dual-Process Model, and the Spiral Model of Grieving and Healing. Many new concepts challenge traditional views by acknowledging diverse grieving styles and validating enduring connections with the deceased. The constructionist approach further provides a valuable framework to support those who are grieving. Readers will gain a deeper understanding of the complexities of grief, along with practical frameworks that can be applied in real-world contexts to support those navigating loss.
