The most widely known model describes five stages of grief: denial, anger, bargaining, depression, and acceptance. But that’s not the only framework. An expanded version lists seven stages, and several alternative models don’t use stages at all. The “right” number depends on which framework you’re looking at, and none of them are meant to be followed like a checklist.
The Original Five Stages
Elisabeth Kübler-Ross introduced the five stages of grief in her 1969 book On Death and Dying. She developed the model after interviewing over two hundred terminally ill patients about their experiences facing death. The stages she identified were denial, anger, bargaining, depression, and acceptance.
A critical detail that often gets lost: Kübler-Ross created this model to describe what dying patients go through, not what bereaved loved ones experience afterward. It was only later that others adapted it as a general framework for grief. The original work was essentially a collection of case studies in the form of conversations with dying patients, not a clinical trial or controlled study.
The Seven-Stage Model
A more recent version expands the list to seven stages by adding two: shock at the beginning and testing between depression and acceptance. Shock refers to the numbed disbelief that hits immediately after a loss, serving as an emotional buffer against being overwhelmed. Testing describes the phase where you start actively searching for practical ways to cope and move forward. The full sequence runs: shock, denial, anger, bargaining, depression, testing, and acceptance.
The addition of shock as a distinct stage resonates with many people’s experience. That initial period where you feel disconnected or unable to process what happened is real and common, and the original five-stage model didn’t give it a name.
Why the Stages Aren’t Really Sequential
Both models are often presented as though grief moves neatly from one stage to the next. That’s not how it works for most people. You might feel acceptance one week and be blindsided by anger the next. Some people never experience certain stages at all. Others cycle back through stages they thought they’d finished with months earlier.
The psychological community has increasingly questioned whether a linear stage model accurately reflects grief. Kübler-Ross herself acknowledged that the stages weren’t meant as a rigid sequence, but the idea of progressing through grief in an orderly fashion took on a life of its own. When your experience doesn’t match the model, it can create unnecessary anxiety that you’re grieving “wrong.” There is no wrong way to grieve.
Alternative Models That Skip Stages Entirely
Several well-respected grief frameworks don’t use stages at all, which is worth knowing if the stage model doesn’t match your experience.
William Worden’s model describes four “tasks” of mourning, things you actively work through rather than passively experience. They are: accepting the reality of the loss, processing the pain of grief, adjusting to a world without the person (learning new skills, adapting routines, shifting your sense of identity), and finding a lasting connection to the person’s memory while re-engaging with life. These aren’t sequential steps. You move in and out of them over time.
British psychiatrists John Bowlby and Colin Murray Parkes proposed four phases of grief: shock and numbness, yearning and searching, disorganization and despair, and reorganization and recovery. This model emphasizes the longing for the person who died and the gradual process of rebuilding daily life. In the final phase, intense feelings of sadness and anger begin to lessen, positive memories increase, and energy levels start to stabilize.
The Dual Process Model, developed by Margaret Stroebe and Henk Schut, takes a completely different approach. It says healthy grieving involves oscillating between two types of coping: focusing on the loss itself (feeling sadness, processing emotions) and focusing on rebuilding your life (taking on new responsibilities, forming new routines, developing a changed identity). Swinging back and forth between these two orientations is normal and healthy. You don’t “complete” one before starting the other.
What Grief Actually Looks Like Over Time
There is no standard timeline for grief. The intensity tends to come in waves that gradually space out over time, but a 35-year study found that for some people, grief fades only after many years have passed. How long it takes depends on the circumstances of the loss, your relationship with the person, and your own personal needs.
Most people find that acute grief, the period of the most intense and disruptive emotions, does ease with time. But “easing” doesn’t mean disappearing. Intense feelings can resurface around anniversaries, holidays, or unexpected reminders. This is normal even years later and doesn’t mean you’ve regressed.
When Grief Becomes a Clinical Concern
Prolonged grief disorder is now a recognized diagnosis in both major diagnostic systems used worldwide. For adults, it applies when grief remains intensely disruptive for at least 12 months after the loss (6 months for children and adolescents). The key distinction isn’t that grief is still present, but that it’s persistently impairing your ability to function in daily life.
Symptoms that may indicate prolonged grief disorder include feeling as though part of yourself has died, a marked sense of disbelief about the death, avoidance of anything that reminds you the person is gone, feeling that life is meaningless without them, and intense loneliness or emotional numbness. A diagnosis requires that these symptoms occur nearly every day for at least a month, and that the grief clearly exceeds what would be expected given your cultural and religious context. Roughly put, this diagnosis exists to identify the small percentage of grieving people who may benefit from targeted professional support, not to pathologize normal bereavement.
Which Model Is “Right”
None of them are universally correct, and that’s actually the point. The five-stage model gave people a common vocabulary for grief, which was valuable. But it was never meant to be a prescription. If your grief looks like the five stages, that’s fine. If it looks like Worden’s four tasks, or a chaotic mix of everything at once, that’s equally fine.
The most useful takeaway across all these models is that grief involves real, identifiable emotional processes, and those processes take time. Whether you count five stages, seven, four tasks, or two oscillating modes of coping, the underlying reality is the same: grief is not a problem to solve quickly. It’s something you live through, in whatever pattern your mind and body need.
