Notes on Chapter 1: Introduction to Psychology in Nursing

Key Messages about Psychology in Nursing

• Humans are more than a collection of organs; care must consider the whole person (biological, psychological, social).
• The patient asks: What caused the illness? What can be done? How can it be prevented? How can they be included in their care? Each of these involves psychological factors.
• Psychology is presented as the most important subject you will study in your nursing degree.
• Health is defined by the World Health Organization (WHO, $1946$) as:

A complete state of physical, mental and social well-being and not merely the absence of disease or infirmity.

This implies that health depends not only on biochemistry, physiology or anatomy but also significant contributions from social and psychological factors.

• The text provocatively states: psychology is the most important topic known to humankind.
• A holistic, person-centred view is emphasized: students should appreciate the individuality and dignity of patients/clients from multiple perspectives.
• The care of patients is linked to ethical and professional standards, including the Nursing and Midwifery Council (NMC) Code of Conduct (2008).
• Quick reminder: there is an implied critique of practice—the field argues for recognizing health and care as including psychosocial dimensions, not just physical illness.

The Role of Psychology in Nursing Practice

• Psychology in nursing practice supports:
  • Communication with patients and clients
  • Adherence to treatment
  • Change of maladaptive behaviour
  • Stress management and coping with the pressures of practice
  • Design of systems and operations in the hospital (theatre) and on the ward
  • Understanding patient needs irrespective of disability or health condition
• The inclusion of psychology aims to tailor care to individuals rather than delivering generic, one-size-fits-all care.

What Is Psychology?

• Etymology: The word psychology comes from two Greek words:
  • psyche (mind, soul, or spirit)
  • logos (knowledge, discourse, or study)
• Consequently, psychology has been defined as the study of mind, behaviour, emotions and thought processes.
• The text emphasizes that psychology helps us understand our patients, clients, and ourselves.

Health Psychology: Definition and Scope

• Health psychology is described as the field concerned with applying psychology to health and healthcare systems.
• It covers aspects related to:
  • Aetiology (the causes) of conditions, or their treatment
  • Promotion and maintenance of health in individuals’ lives
  • Improvement of the health care system and delivery of information to patients
• A formal, but garbled in-text definition is provided in the transcript; the intended meaning is:
  • Health psychology integrates education and professional practice focused on health promotion, disease prevention, health behaviour change, and the optimization of health care delivery.

Connections to Practice, Ethics, and Professional Standards

• The use of psychology in nursing aligns with ethical practice: respecting patient autonomy, dignity, and individual needs.
• It supports the Code of Conduct by the regulatory body (NMC, 2008) through:
  • Safe, effective, patient-centred care
  • Clear communication and collaboration with patients and families
  • Professional accountability and reflective practice
• Psychology informs both direct patient care (communication, adherence, behaviour change) and systems-level decisions (how wards/theatres are designed and operated) to support better outcomes.

Examples, Metaphors, and Hypothetical Scenarios

• Example: A patient with chronic illness struggles to adhere to medication. A psychologist-informed approach would explore beliefs about illness, perceived barriers, and social supports, then tailor education and support to increase adherence.
• Hypothetical scenario: In designing a care plan for an elderly patient with multiple comorbidities, a nurse uses psychological principles to address fear of hospitalization, fosters involving the patient in decision-making, and uses simple, culturally sensitive explanations to improve engagement.
• Metaphor: Viewing health as a tripod with three legs—biological, psychological, and social—where removing one leg destabilizes the whole structure.

Key Concepts and Takeaways

• Holistic care requires integrating psychological and social factors with physical illness.
• Psychology enhances: understanding of individuality, patient dignity, communication, adherence, behaviour change, and system design.
• Health psychology applies psychological theory to promote health, prevent illness, and improve health care systems and information.
• The field supports ethical, patient-centred care aligned with professional standards (NMC Code of Conduct, 2008).

Foundational Definitions and Terminology

• Psychology: the study of mind, behaviour, emotions and thought processes; etymology from:
  • 
    $ext{psyche}$ = mind, soul, or spirit
  • 
    $ext{logos}$ = knowledge, discourse, or study
• Health psychology: the application of psychological knowledge and methods to the promotion and maintenance of health, prevention of illness, and optimization of health care systems and information.

Connections to Prior and Real-World Relevance

• Aligns with foundational nursing principles of holistic, patient-centred care.
• Supports real-world nursing goals: better patient outcomes, improved adherence, reduced distress for patients and staff, and more efficient health-care delivery.
• Ethical considerations include respecting autonomy, informed consent, and dignity when applying psychological approaches.

Quick Check Reflections

• How does recognizing psychological factors change the approach to a common nursing task (e.g., patient education, discharge planning, or adherence support)?
• In what ways can hospital design and processes (ward layouts, theatre scheduling) benefit from psychology-informed improvements?
• How does health psychology differ from general psychology in its aims and applications within health care?
