Tidal Model

Last updated

The Tidal Model [1] [2] is a recovery model for the promotion of mental health developed by Professor Phil Barker, Poppy Buchanan-Barker and their colleagues. The Tidal Model focuses on the continuous process of change inherent in all people. It seeks to reveal the meaning of people's experiences, emphasising the importance of their own voice and wisdom through the power of metaphor. It aims to empower people to lead their own recovery rather than being directed by professionals. [3]


The philosophy underpinning the model initially was inspired by a five year research into what people need for care in mental health carried out by Prof. Barker and Dr. Chris Stevenson at the University of Newcastle, UK. [4] Since 2000, it has been put into practice in a number of settings in the UK and abroad. [5]

Due to the work of Phil Barker in this area, he is frequently cited as being a prominent contemporary theorist in mental health nursing. [2] [3]

Six key philosophical assumptions

The tidal model is applied through six key philosophical assumptions: [5]

The engagement process

In order for the practitioner to begin the process of engagement using the Tidal Model, the following needs to be accepted:

The process of engaging with the person in distress takes place in three discrete domains. [1] With the Tidal Model, the practitioner explores these dimensions to be aware of the situation in the present time and determine what needs to happen now.

The power of metaphor

The Tidal Model uses the metaphor of water and describes how people in distress can become emotionally, physically and spiritually shipwrecked. [1] It sees the experience of health and illness as a fluid, rather than a stable phenomenon, and life as a journey undertaken on an ocean of experience. It proposes that in mental health, the factors associated with a psychiatric crisis, or its more enduring consequences, can be diverse as well as cumulative. It states that by appreciating this metaphor, nurses or other helpers will gain a greater understanding of the person's current situation and the inevitability of change. With this, the helper may, in time, be guided to care with the person beginning their journey from the state of being washed ashore, drowning or being otherwise marooned by their life problems. Following the rescue, exploration can then begin as to what caused the storm in the first place and what needs to be done immediately to set sail again.

The Ten Commitments

The values of the Tidal Model can be distilled into Ten Commitments. [1]

  1. Value the voice – the person's story is paramount
  2. Respect the language – allow people to use their own language
  3. Develop genuine curiosity – show interest in the person's story
  4. Become the apprentice – learn from the person you are helping
  5. Reveal personal wisdom – people are experts in their own story
  6. Be transparent – both the person and the helper, Professionals are in a privileged position and should model confidence, by at all times being transparent and helping to ensure the person understand exactly what is being done [6]
  7. Use the available toolkit – the person's story contains valuable information as to what works and what doesn't
  8. Craft the step beyond – the helper and the person work together to construct an appreciation of what needs to be done "now"
  9. Give the gift of time – time is the midwife of change. The question that should be asked is, "How do we use this time?". [7]
  10. Know that change is constant – this is a common experience for all people

The Twenty Competencies

The Twenty Competencies were introduced to assist with the auditing of recovery practice by generating practice-based evidence for the model. They focus on competencies in practice and there are two related to each of the commitments above. [5]

The model in practice

In 2000, the Tidal Model was first implemented in Newcastle-upon-Tyne, UK in the adult mental health programme covering nine acute admission wards. Almost 100 different Tidal Model projects were established in the UK, Ireland, New Zealand, Canada, Japan and Australia. [5] However, it has yet to be broadly adopted.

Anti-psychiatry is a movement based on the view that psychiatric treatment is more often damaging than helpful to patients. It considers psychiatry a coercive instrument of oppression due to an unequal power relationship between doctor and patient and a highly subjective diagnostic process. It has been active in various forms for two centuries.

Occupational therapy therapy to increase skills related to work or independent living

Occupational therapy (OT) is the use of assessment and intervention to develop, recover, or maintain the meaningful activities, or occupations, of individuals, groups, or communities. It is an allied health profession performed by occupational therapists and occupational therapy assistants (OTA). OTs often work with people with mental health problems, disabilities, injuries, or impairments.

Hearing Voices Networks, closely related to the Hearing Voices Movement, are peer-focused national organisations for people who hear voices and supporting family members, activists and mental health practitioners. Members may or may not have a psychiatric diagnosis. Networks promote an alternative approach, where voices are not necessarily seen as signs of mental illness. Networks regard hearing voices as a meaningful and understandable, although unusual, human variation. In themselves voices are not seen as the problem. Rather it is the relationship the person has with their voices that is regarded as the main issue.


De-escalation refers to behavior that is intended to escape escalations of conflicts. It may also refer to approaches in conflict resolution. Escalations of commitment are often hard from spiraling out of proportions without specific measures being taken.

Recovery International is a mental health self-help organization founded in 1937 by neuropsychiatrist Abraham Low in Chicago, Illinois. Recovery's program is based on self-control, self-confidence, and increasing one's determination to act. Recovery deals with a range of people, all of whom have difficulty coping with everyday problems, whether or not they have a history of psychiatric hospitalization. It is non-profit, secular, and although it uses methods devised by Low, most groups are currently led by experienced non-professionals.

Psychiatric nursing or mental health nursing is the appointed position of a nurse that specialises in mental health, and cares for people of all ages experiencing mental illnesses or distress. These include: schizophrenia, schizoaffective disorder, mood disorders, anxiety disorders, personality disorders, eating disorders, suicidal thoughts, psychosis, paranoia, and self-harm.

Reflective practice is the ability to reflect on one's actions so as to engage in a process of continuous learning. According to one definition it involves "paying critical attention to the practical values and theories which inform everyday actions, by examining practice reflectively and reflexively. This leads to developmental insight". A key rationale for reflective practice is that experience alone does not necessarily lead to learning; deliberate reflection on experience is essential.

A mental health consumer is a person who is obtaining treatment or support for a mental disorder, also known as psychiatric or mental illness. The term was coined by people who use mental health services in an attempt to empower those with mental health issues, usually considered a marginalized segment of society. The term suggests that there is a reciprocal contract between those who provide a service and those who use a service and that individuals have a choice in their treatment and that without them there could not exist mental health providers.

Residential care refers to long-term care given to adults or children who stay in a residential setting rather than in their own home or family home.

A mental health professional is a health care practitioner or social and human services provider who offers services for the purpose of improving an individual's mental health or to treat mental disorders. This broad category was developed as a name for community personnel who worked in the new community mental health agencies begun in the 1970s to assist individuals moving from state hospitals, to prevent admissions, and to provide support in homes, jobs, education, and community. These individuals were the forefront brigade to develop the community programs, which today may be referred to by names such as supported housing, psychiatric rehabilitation, supported or transitional employment, sheltered workshops, supported education, daily living skills, affirmative industries, dual diagnosis treatment, individual and family psychoeducation, adult day care, foster care, family services and mental health counseling.

The psychiatric survivors movement is a diverse association of individuals who either currently access mental health services, or who are survivors of interventions by psychiatry, or who are ex-patients of mental health services.

Nurse–client relationship interaction between client/patient and nurse

The nurse–client relationship is an interaction aimed to enhance the well-being of a "client," which may be an individual, a family, a group, or a community. Peplau's theory is of high relevance to the nurse-client relationship, with one of its major aspects being that both the nurse and the client become more knowledgeable and mature over the course of their relationship. Peplau believed that the relationship depended on the interaction of the thoughts, feelings, and actions of each person and that the patient will experience better health when all their specific needs are fully considered in the relationship. The nurse-patient relationship enables nurses to spend more time, to connect, to interact with their patients as well as to understand their patient's needs. It assists nurses to establish a unique perspective regarding the meaning of the patient's illness, beliefs, and preferences of patients/families. Thus, the patients/families feel that they are being cared for and they feel more motivated to open up to the nurses as well as working together to achieve better outcomes/satisfaction.

Founded by Will Hall and Oryx Cohen, the Freedom Center is a Northampton, Massachusetts-based support, activism, and human rights community run by and for people diagnosed with severe mental illness, such as schizophrenia, bipolar disorder, borderline personality disorder and obsessive-compulsive disorder.

Psychological recovery or recovery model or the recovery approach to mental disorder or substance dependence emphasizes and supports a person's potential for recovery. Recovery is generally seen in this approach as a personal journey rather than a set outcome, and one that may involve developing hope, a secure base and sense of self, supportive relationships, empowerment, social inclusion, coping skills, and meaning. Recovery sees symptoms as a continuum of the norm rather than an aberration and rejects sane-insane dichotomy.

In the United States, a psychiatric-mental health nurse practitioner (PMHNP) is an advanced practice registered nurse trained to provide a wide range of mental health services to patients and families in a variety of settings. PMHNPs diagnose, conduct therapy, and prescribe medications for patients who have psychiatric disorders, medical organic brain disorders or substance abuse problems. They are licensed to provide emergency psychiatric services, psychosocial and physical assessment of their patients, treatment plans, and manage patient care. They may also serve as consultants or as educators for families and staff. The PMHNP has a focus on psychiatric diagnosis, including the differential diagnosis of medical disorders with psychiatric symptoms, and on medication treatment for psychiatric disorders.

Mentalism or sanism describes discrimination and oppression against a mental trait or condition a person has, or is judged to have. This discrimination may or may not be characterized in terms of mental disorder or cognitive impairment. The discrimination is based on numerous factors such as stereotypes about neurodivergence, for example [Aspergers], learning disorders, ADHD, bipolar, schizophrenia, and personality disorders, specific behavioral phenomena such as stuttering and tics, or intellectual disability.

The Critical Psychiatry Network (CPN) is a psychiatric organization based in the United Kingdom. It was created by a group of British psychiatrists who met in Bradford, England in January 1999 in response to proposals by the British government to amend the 1983 Mental Health Act (MHA). They expressed concern about the implications of the proposed changes for human rights and the civil liberties of people with mental health illness. Most people associated with the group are practicing consultant psychiatrists in the United Kingdom's National Health Service (NHS), among them Dr Joanna Moncrieff. A number of non-consultant grade and trainee psychiatrists are also involved in the network.

Wellness Recovery Action Plan (WRAP) is a recovery model developed by a group of people in northern Vermont in 1997 in a workshop on mental health recovery led by Mary Ellen Copeland. It has been extensively studied and is now an evidence-based practice, listed in the SAMSHA National Registry of Evidence-Based Programs and Practices (NREPP).

A Mental Health Nurse (MHN) refers to a psychiatric nurse in the UK, who specialises in the care of patients with mental health issues.
