Several researchers have described the emotional roller coaster a person goes through in connection with crises or major changes.

Two of the most widespread are Claes Janssen's "The Four Rooms of Change" and Kubler-Ross' "Five stages of grief".


The Claes Janssen's "Four rooms of  Change" model

From the Swedish Wikipedia:
The Four Rooms of Change is a theory of change. It is used to analyze how people and organizations react in crisis and development, under stress and external pressure.

The theory of the Four Rooms of Change is based on Claes Janssen's research at Stockholm University. In his research, Claes Janssen discovered a movement between four basic psychological states, which all people seemed to go through in shorter or longer cycles of their lives.
The core of the theory is a four-part model, the "four-room-matrix", which shows how an individual or a group travels through different stages in a change process.

The four parts are
  • satisfaction
  • censorship / denial
  • confusion and conflict
  • inspiration / renewal
Since 1993, the theory has been applied in working life through a number of diagnostic tools, such as the Organizational Barometer. The Swedish furniture company IKEA has been using the concept throughout the group since 1996. Over time, The Four Rooms of Change has also become widespread in, for examples in schools and in sports.

The Four Rooms of Change, and its various applications, have gained great Swedish and international attention over the years and some of Janssen's texts and pedagogical tools have been translated into more than ten languages. Two of Janssen's books have been published in English.

The Kübler-Ross model or Five stages of grief

From Wikipedia:
The five stages of grief model (or the Kübler-Ross model) postulates that those experiencing grief go through a series of five emotions: denial, anger, bargaining, depression, and acceptance. The model was introduced by Swiss-American psychiatrist Elisabeth Kübler-Ross in her 1969 book On Death and Dying, and was inspired by her work with terminally ill patients.... 
...Kübler-Ross originally developed stages to describe the process patients with terminal illness go through as they come to terms with their own deaths; it was later applied to grieving friends and family as well, who seemed to undergo a similar process.
The stages, popularly known by the acronym DABDA, include: 

  1. Denial – The first reaction is denial. In this stage, individuals believe the diagnosis is somehow mistaken, and cling to a false, preferable reality.
  2. Anger – When the individual recognizes that denial cannot continue, they become frustrated, especially at proximate individuals. Certain psychological responses of a person undergoing this phase would be: "Why me? It's not fair!"; "How can this happen to me?"; "Who is to blame?"; "Why would this happen?".
  3. Bargaining – The third stage involves the hope that the individual can avoid a cause of grief. Usually, the negotiation for an extended life is made in exchange for a reformed lifestyle. People facing less serious trauma can bargain or seek compromise. Examples include the terminally ill person who "negotiates with God" to attend a daughter's wedding, an attempt to bargain for more time to live in exchange for a reformed lifestyle or a phrase such as "If I could trade their life for mine".
  4. Depression – "I'm so sad, why bother with anything?"; "I'm going to die soon, so what's the point?"; "I miss my loved one; why go on?"
    During the fourth stage, the individual despairs at the recognition of their mortality. In this state, the individual may become silent, refuse visitors and spend much of the time mournful and sullen.
  5. Acceptance – "It's going to be okay."; "I can't fight it; I may as well prepare for it."
    In this last stage, individuals embrace mortality or inevitable future, or that of a loved one, or other tragic event. People dying may precede the survivors in this state, which typically comes with a calm, retrospective view for the individual, and a stable condition of emotions. 
Disputes regarding the Five stages of grief:
  • Later in her life, Kübler-Ross noted that the stages are not a linear and predictable progression and that she regretted writing them in a way that was misunderstood. "Kübler-Ross originally saw these stages as reflecting how people cope with illness and dying," observed grief researcher Kenneth J. Doka, "not as reflections of how people grieve." 
  • Although commonly referenced in popular culture, studies have not empirically demonstrated the existence of these stages, and the model is considered to be outdated, inaccurate and unhelpful in explaining the grieving process.
