Stages of Grief: Understanding the Kübler-Ross Model and Modern Grief Theory

The stages of grief refer to a widely known framework for understanding the emotional responses people experience after a significant loss. Originally proposed by psychiatrist Elisabeth Kübler-Ross in her 1969 book On Death and Dying, the model identifies five stages: denial, anger, bargaining, depression, and acceptance. These stages were intended to describe the emotional landscape of people facing their own terminal illness, though they were quickly adopted by popular culture as a universal roadmap for all forms of grief.

It is critical to understand from the outset that Kübler-Ross herself never intended these stages to be a rigid, linear sequence. She later clarified that the stages are not meant to be experienced in order, that not everyone goes through all of them, and that grief is far more individualized and complex than any single model can capture. Despite this, the "five stages" became one of the most recognized — and most misunderstood — frameworks in psychology and popular culture.

In clinical practice, grief is not classified as a mental disorder in itself. The DSM-5-TR (Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, Text Revision) distinguishes between normal grief responses and Prolonged Grief Disorder, a condition newly added to the manual that involves persistent, debilitating grief lasting beyond expected social, cultural, or religious norms. Understanding the stages of grief in their proper context — as one descriptive lens, not a prescriptive checklist — is essential for anyone navigating loss or supporting someone who is.

Elisabeth Kübler-Ross was a Swiss-American psychiatrist who spent extensive time interviewing terminally ill patients at the University of Chicago. Her groundbreaking work challenged the medical establishment's tendency to avoid discussions of death and dying. On Death and Dying grew out of a seminar series she led in which dying patients shared their experiences directly with medical students and healthcare professionals.

From these interviews, Kübler-Ross identified recurring emotional patterns that she organized into five stages:

• Denial: An initial reaction of disbelief or shock — "This can't be happening." Denial functions as a temporary defense mechanism that buffers the immediate impact of loss.
• Anger: As denial fades, frustration and helplessness may emerge, often directed at others, at circumstances, or at oneself. "Why me?" or "This isn't fair" are characteristic expressions.
• Bargaining: An attempt to negotiate or regain control, often involving "if only" or "what if" thinking. In the context of terminal illness, this sometimes involves bargaining with a higher power.
• Depression: A deep sadness that reflects the weight of the loss. This is not clinical depression in the diagnostic sense, but rather a profound mourning response — a period of withdrawal and sorrow.
• Acceptance: Not happiness or "being okay" with the loss, but rather an acknowledgment of the reality. Acceptance involves learning to live with the new reality rather than fighting it.

The model was revolutionary for its time. It gave language to experiences that were previously unspoken in clinical settings and opened the door to the modern hospice and palliative care movements. However, Kübler-Ross developed the model based on qualitative clinical observation, not controlled empirical research, which is an important distinction when evaluating its scientific standing.

Several key principles underlie a proper understanding of the grief stages model — principles that are frequently lost in popular retellings:

1. The stages are not linear. Grief does not move in a clean progression from denial to acceptance. A person may experience anger before denial, return to bargaining after a period of acceptance, or cycle through multiple stages in a single day. Kübler-Ross and co-author David Kessler explicitly stated in their 2005 book On Grief and Grieving that the stages are "not stops on some linear timeline in grief."

2. Not everyone experiences all five stages. Some people may never feel anger. Others may not go through a distinct bargaining phase. The model describes common emotional responses, not universal or mandatory ones.

3. The stages were originally about dying, not bereavement. The model was developed from interviews with people facing their own deaths. Its application to bereavement (grieving the loss of someone else) came later, largely through popular interpretation rather than rigorous clinical extension.

4. Grief is shaped by context. Cultural background, the nature of the relationship, the circumstances of the loss (sudden versus anticipated, violent versus peaceful), personal resilience, social support, and prior mental health all profoundly influence how a person grieves. No single model accounts for all of this variability.

5. Acceptance does not mean resolution or closure. Acceptance in the Kübler-Ross framework means acknowledging the permanence of the loss, not feeling good about it. Many bereaved people carry their grief indefinitely — not as pathology, but as a natural reflection of enduring love and attachment.

The empirical evidence for the Kübler-Ross stage model as a sequential or predictive framework is limited. Multiple systematic reviews and empirical studies have found that grief does not unfold in a predictable stage-based pattern for most people.

A landmark 2007 study published in the Journal of the American Medical Association (JAMA) by Maciejewski and colleagues examined grief indicators in 233 bereaved individuals over a two-year period. The study found that acceptance was the most frequently endorsed emotion at every time point — not denial, as the stage model would predict. While the study found some evidence that specific grief indicators peaked in a sequence loosely consistent with the model, the overall findings did not support a rigid stage framework. Disbelief was not the dominant initial experience for most participants, and yearning — not depression or anger — was the dominant negative grief experience.

Research by George Bonanno at Columbia University has been particularly influential in reshaping scientific understanding of grief. His longitudinal studies have consistently shown that the most common trajectory after loss is resilience — a majority of bereaved individuals show relatively stable psychological functioning and do not pass through prolonged periods of intense distress. Bonanno's research identifies multiple distinct grief trajectories, including:

• Resilience: Stable, relatively low distress throughout (the most common pattern)
• Recovery: Elevated distress followed by gradual improvement
• Chronic grief: Prolonged, elevated distress that does not resolve
• Delayed grief or depression: Distress that emerges or intensifies well after the loss

These findings fundamentally challenge the idea that intense grief is universal or that failure to show distress is pathological. The field has largely moved toward individualized, trajectory-based models of grief rather than universal stage models.

Other influential frameworks include Stroebe and Schut's Dual Process Model, which describes bereaved individuals as oscillating between loss-oriented coping (processing the grief itself) and restoration-oriented coping (adapting to practical life changes). This oscillation model has stronger empirical support than stage-based approaches and better accounts for the day-to-day variability most grieving people experience.

While grief itself is a normal and expected response to loss, research has established that a subset of bereaved individuals — estimated at roughly 7-10% of bereaved adults — develop a condition characterized by persistent, intense grief that significantly impairs daily functioning well beyond culturally expected timeframes.

The DSM-5-TR, published in 2022, officially codified Prolonged Grief Disorder (PGD) as a diagnosable condition. Key diagnostic criteria include:

• The death of a person close to the bereaved occurred at least 12 months prior (6 months for children and adolescents)
• Since the death, the individual experiences intense longing or yearning for the deceased, or preoccupation with thoughts or memories of the deceased, nearly every day
• At least three of the following symptoms at a clinically significant level: identity disruption, marked disbelief about the death, avoidance of reminders, intense emotional pain, difficulty reintegrating into life, emotional numbness, feeling that life is meaningless, and intense loneliness
• The disturbance causes clinically significant impairment in social, occupational, or other important functioning
• The duration and severity of the grief response clearly exceed expected social, cultural, or religious norms

The inclusion of PGD in the DSM-5-TR was controversial. Critics expressed concern that pathologizing grief could lead to the medicalization of normal human suffering. Proponents argued that formally recognizing the condition would improve access to targeted treatment for the small percentage of people whose grief is genuinely debilitating and who were previously falling through diagnostic cracks.

It is important to distinguish PGD from Major Depressive Disorder (MDD) triggered by bereavement. While they can co-occur, PGD is characterized primarily by yearning and preoccupation with the deceased, whereas MDD involves broader symptoms like pervasive low mood, anhedonia, and cognitive disturbances that extend beyond the loss itself. The DSM-5-TR requires clinicians to carefully assess whether the presentation is better explained by depression, PTSD, or another condition.

In clinical settings, the stages of grief model is rarely used as a formal assessment or treatment framework. Instead, it serves as a psychoeducational tool — a way of helping patients understand that their emotional experiences, however chaotic, are common and not signs of failure or pathology.

For normal grief, research supports the following approaches:

• Supportive counseling: Providing a safe space for the bereaved person to process emotions, tell their story, and feel heard. This is often sufficient for individuals on a resilient or recovery trajectory.
• Psychoeducation: Normalizing the grief experience, explaining that there is no "right" way to grieve, and providing information about common grief responses. This is where the stages model can be helpful — as long as it is presented as descriptive, not prescriptive.
• Social support facilitation: Helping the bereaved individual identify and engage their support network. Research consistently shows that perceived social support is one of the strongest protective factors in grief outcomes.

For Prolonged Grief Disorder, more targeted interventions are warranted:

• Prolonged Grief Disorder Therapy (PGDT): Developed by M. Katherine Shear at Columbia University, this is the most empirically supported treatment for PGD. It integrates elements of cognitive-behavioral therapy, interpersonal therapy, and motivational interviewing. The treatment involves revisiting the story of the death (similar to trauma-focused exposure), addressing maladaptive thoughts, and setting personal goals for re-engagement with life.
• Cognitive-Behavioral Therapy (CBT): Standard CBT can address maladaptive thought patterns and avoidance behaviors that maintain prolonged grief.
• Medication: There is limited but emerging evidence for pharmacological interventions. Some research suggests that certain antidepressants may reduce symptoms, particularly when PGD co-occurs with Major Depressive Disorder. However, medication alone is generally not considered a first-line treatment for grief.

Clinicians are trained to assess for risk factors that increase vulnerability to complicated grief outcomes, including: a history of prior losses or trauma, insecure attachment style, loss of a child or life partner, sudden or violent death, social isolation, and pre-existing mental health conditions.

Few concepts in psychology have been as widely embraced — and as widely misapplied — as the stages of grief. Correcting common misconceptions is essential for both the public and healthcare providers:

Misconception 1: "Everyone goes through five stages in order."
This is the most pervasive myth. Grief is not an orderly process with a clear beginning, middle, and end. Research consistently shows that emotional responses to loss are highly variable, non-linear, and individualized. Some people experience predominantly one emotion; others oscillate unpredictably.

Misconception 2: "If you don't grieve intensely, something is wrong with you."
Bonanno's research demonstrates that resilience — not prolonged distress — is the most common response to bereavement. People who show stable functioning after a loss are not in denial; they are coping effectively. Pressuring people to express grief they don't feel can actually be harmful.

Misconception 3: "Grief has a timeline — you should be 'over it' by a certain point."
There is no universal timeline for grief. While Prolonged Grief Disorder has a 12-month benchmark for diagnostic purposes, this reflects clinical impairment, not a deadline for emotional healing. Many people carry grief for a lifetime without it being pathological.

Misconception 4: "The stages of grief apply to all types of loss."
While the model is frequently applied to divorce, job loss, disability, and other non-death losses, it was originally developed in the context of terminal illness. Applying it universally, without considering the unique features of different types of loss, oversimplifies complex psychological experiences.

Misconception 5: "Acceptance means you've moved on."
Acceptance in the grief context means acknowledging the reality of the loss. It does not mean the pain disappears, the person is forgotten, or life returns to how it was before. Many bereaved individuals describe learning to carry their grief rather than getting over it.

Misconception 6: "Grief counseling is necessary for everyone who experiences loss."
Research suggests that routine grief counseling for individuals who are coping normally is not beneficial and can sometimes interfere with natural coping processes. Targeted intervention is most appropriate for those showing signs of prolonged or complicated grief.

Understanding the limitations of the stage model does not mean abandoning frameworks for grief entirely. Instead, it means approaching grief with flexibility, compassion, and realistic expectations. Here are evidence-informed practical implications:

For individuals experiencing grief:

• There is no "right" way to grieve. If your experience doesn't match a model you've read about, that does not mean something is wrong with you. Grief is as individual as the relationship you lost.
• Allow yourself to oscillate. Consistent with the Dual Process Model, it is healthy and normal to move between confronting your grief and taking breaks from it — engaging with daily tasks, experiencing moments of enjoyment, and then returning to sadness.
• Be wary of comparisons. How someone else grieved a similar loss is not a benchmark for your experience. Cultural, personal, and relational factors make every grief journey unique.
• Maintain basic self-care. Sleep, nutrition, physical activity, and social connection are not luxuries during grief — they are foundations that support your capacity to cope.
• Monitor for warning signs. If your grief is intensifying rather than gradually fluctuating over many months, if you are unable to function in daily life, if you are having persistent thoughts of suicide or self-harm, or if you are using substances to cope, these are indicators that professional support is needed.

For those supporting a grieving person:

• Listen more than you advise. Avoid telling the person what stage they are in or where they should be. Presence and empathy are more helpful than frameworks.
• Don't impose timelines. Statements like "it's been six months" or "you should be moving on" are among the most harmful things a grieving person can hear.
• Offer specific, practical help. Rather than saying "let me know if you need anything," offer concrete support: meals, childcare, transportation, or help with administrative tasks related to the loss.
• Stay present over time. Social support often floods in immediately after a loss and then disappears. The weeks and months that follow — when shock fades and grief intensifies — are often when support is needed most.

Most people do not need professional mental health treatment to navigate grief. However, certain signs indicate that a professional evaluation is appropriate:

• Persistent inability to function in work, school, relationships, or daily self-care for an extended period (months, not days or weeks)
• Intense, unrelenting yearning or preoccupation with the deceased that does not fluctuate or ease over time
• Pervasive feelings of meaninglessness, emptiness, or identity loss that are not improving
• Avoidance of all reminders of the deceased, or On the other hand, an inability to detach from reminders to an extent that disrupts daily life
• Suicidal thoughts or self-harm behaviors — these warrant immediate professional attention
• Increased substance use as a coping mechanism
• Symptoms consistent with Major Depressive Disorder, PTSD, or anxiety disorders that develop in the wake of the loss

A qualified mental health professional — such as a licensed psychologist, clinical social worker, or psychiatrist — can assess whether the grief response falls within the range of normal bereavement or whether patterns consistent with Prolonged Grief Disorder, depression, or another condition may be present. Early identification and targeted intervention for complicated grief can significantly improve outcomes.
