Psychological Adjustment Processes in Terminal Illness
When an individual realizes that a fatal illness threatens their life, they begin a complex process of coming to terms with their mortality. This confrontation has been documented for centuries through diaries, poetry, and medical reports. However, since the mid-20th century, the social sciences have shifted toward empirical data and field research to understand the "fight" against death. These theories and models are primarily designed to support caregivers and professionals in the accompaniment of terminally ill patients.
The study of dying involves various psychosocial aspects—the intersection of social factors and individual psychological health. Key concepts in this field include Total Pain (C. Saunders), Acceptance (J. M. Hinton, Kübler-Ross), Awareness/Insecurity (B. Glaser, A. Strauß), and Autonomy (H. Müller-Busch), among others such as fear, ambivalence, and the response to challenges.
[ไม่มีภาพประกอบ]Key Facts
- Thanatology (the scientific study of death) utilizes various phase and stage models to describe the psychological journey of the dying.
- The Five Stages of Grief is the most famous model, though it is often criticized for being applied too rigidly.
- Modern research emphasizes individuality, suggesting that no two people experience death in exactly the same way.
- Awareness levels range from "Closed" (patient is unaware) to "Open" (everyone is aware and honest).
- Caregivers are encouraged to resolve their own "unfinished business" regarding death to better support patients.
Phase and Stage Models of Dying
Psychologists have developed numerous models to categorize the course of dying, with some proposing as few as three phases and others as many as twelve.
The Illness Constellation Model
Published in 1991, this revised model associates the dying process with specific psychological states: initial shock, dizziness, and uncertainty upon diagnosis; efforts to maintain control and shifting emotional states; withdrawal and grief over lost abilities; and finally, a psycho-physical decline.
The Five Stages of Grief (Kübler-Ross Model)
Developed by Swiss-US psychiatrist Elisabeth Kübler-Ross, this model synthesized findings from other thanatologists like John Hinton and Cicely Saunders. The five stages are:
- Denial and Isolation
- Anger
- Bargaining
- Depression
- Consent (Acceptance)
Kübler-Ross emphasized that hope is typically present in every phase and should never be taken away, as its loss often precedes death. She also noted that these stages are not linear; they can repeat, alternate, or be skipped entirely. Furthermore, she argued that helpers must first accept their own mortality and clarify their own life problems before they can effectively assist the dying.
Factors Influencing the Dying Process
Due to scientific objections to rigid stage models, many researchers now focus on the specific factors that influence an individual's experience. Robert J. Kastenbaum posits that dying is a combination of universality and individuality.
The Kastenbaum and Engelke Perspectives
Kastenbaum identifies age, gender, religion, culture, and interpersonal relationships as key influencers. Ernst Engelke expanded this, arguing that while all terminally ill people face common realizations (such as the threat to their life) and constraints (such as side effects of therapy), the actual experience is unique to each person.
According to Engelke, the unique experience of death results from the interaction of:
- Personal resources: Genetics, personality, life experience, and spiritual or financial resources.
- Medical factors: The type and duration of the disease and the quality of care.
- Environmental factors: The physical surroundings, such as a clinic or home.
- Social factors: The expectations and behaviors of doctors, carers, and relatives.
| Model/Theory | Primary Focus | Key Characteristic |
|---|---|---|
| Kübler-Ross | Emotional Stages | Five non-linear stages: Denial, Anger, Bargaining, Depression, Consent. |
| Illness Constellation | Psychological Progression | Moves from initial shock to psycho-physical decline. |
| Kastenbaum/Engelke | Individual Factors | Focuses on the interaction of personal, social, and medical variables. |
| Glaser & Strauss | Awareness Levels | Categorizes how information about death is shared among participants. |
Awareness and Ethics in End-of-Life Care
A significant debate in sociology and psychology concerns whether patients should be informed of an infaust prognosis (a forecast that the disease cannot be cured). In 1965, Barney G. Glaser and Anselm Strauss identified four types of awareness:
- Closed Awareness: Only medical staff and relatives know; the patient is unaware.
- Suspected Awareness: The patient suspects the truth, but no one confirms it.
- Mutual Pretense Awareness: Everyone knows, but everyone pretends they do not.
- Open Awareness: Everyone acknowledges the reality of the situation.
The Hospice Movement in the UK advocates for Open Awareness, arguing that truthful and trustful interaction prevents the breakdown of relationships and ensures better treatment.
Frequently Asked Questions
Do patients always go through the five stages of grief in order?
No. Elisabeth Kübler-Ross herself noted that the stages are not experienced in a fixed sequence. They can repeat, alternate, or some stages may be skipped entirely.
What is the difference between Closed and Mutual Pretense Awareness?
In Closed Awareness, the patient is the only one who does not know they are dying. In Mutual Pretense Awareness, the patient is aware (or suspects it), and the caregivers are aware, but both parties agree to act as if the illness is not fatal.
Why is hope considered important in the dying process?
According to the Kübler-Ross model, hope is almost always present across all phases. It is viewed as a vital psychological support, and its complete loss is often seen as a precursor to death.
What factors make the experience of dying unique for each person?
As suggested by Ernst Engelke, uniqueness stems from a combination of genetic makeup, personality, life experiences, the specific nature of the illness, the quality of medical care, and the support provided by relatives and society.
How should caregivers prepare themselves to help the terminally ill?
Research suggests that caregivers should first address their own fears and "unfinished business" regarding death. By accepting their own mortality, they are better equipped to provide helpful and empathetic support to patients.
