What is Health Psychology?
Health psychologists specialise in understanding the connection between
physical, psychological and social health.
Health psychologists work to promote positive health behaviours and
reduce harmful health behaviours.
Health psychologists work with other health professionals and advise on
attitudes, beliefs and behaviours that contribute to ill health, and how they
might be changed.
What do Health Psychologists do?
Health psychologists have expertise in developing education and
behaviour change programs to help people to recover from, and/or to
self-manage acute and/or chronic illness, trauma, injury or disability
Health psychologists design and evaluate interventions to improve
communication and relationships between multidisciplinary health
professionals, the functioning of health systems
Health psychologists may work one-on-one, in groups, systems,
communities or populations
Health Psychology Areas of
Practice
- Health Promotion - Concerned with illness prevention and
promotion of health. - Clinical Health Psychology - Applying psychology to illness diagnosis,
adjustment, treatment, and rehabilitation.
Defining Health Promotion
In the Ottawa Charter (1986), the WHO stated:
“Health promotion is the process of enabling people to increase control
over, and to improve, their health. To reach a state of complete physical,
mental and social well-being, an individual or group must be able to
identify and to realize aspirations, to satisfy needs, and to change or
cope with the environment. Health is, therefore, seen as a resource for
everyday life, not the objective of living. Health is a positive concept
emphasizing social and personal resources, as well as physical capacities.
Therefore, health promotion is not just the responsibility of the health
sector, but goes beyond healthy life-styles to well-being.”
Health Promotion Aims
Aims to:
* Promote positive health behaviours and reduce harmful health
behaviours
* Reduce risk factors associated with chronic conditions
* Identify and address attitudes, beliefs and behaviours that contribute
to ill health
- Design behaviour change-related public
health programs - Gather data about disease and ill-health and
identify health behaviours and modifiable
determinants of health and wellbeing
What are Common Health
Promotion Campaigns?
- smoking
- physical activity
- diet
- alcohol
- R U OK
- White Ribbon
- Cancer Screening
- Drink Driving
- Drug Driving
- B Part of It
- Covid-19
- Blood Donation
- Sunsmart - Slip, Slop, Slap, Seek, Slide.
Clinical Health Psychology
Aims to:
* Design education and behaviour change interventions to improve
health for people with health conditions
* Assist with psychosocial issues that can contribute to or accompany
health conditions
* Assist people to cope with diagnoses and medical treatment
* Assist people to cope with terminal illness

Biopsychosocial Model
Interactive and bi-directional influences amongst 3 dimensions
- Biological-physiological - genetics, biochemistry, immunology
- Psychological-behavioural - thoughts, beliefs, expectations, habits
- Social-environmental - family and cultural context, financial stability,
SES, access to health care, environmental stressors
Behaviour Change with regard to addiction and health barriers
Behavioural approach: the easy option?
◦ Think of a health behaviour you tried to change
recently
◦ Barriers?
◦ If behaviour change was achieved, for how long
was it maintained?
Health Beliefs
The “social cognitive” models seen in health psychology in recent years
aim to predict health-related behaviours such as:
◦ health behaviours
◦ self-care
◦ adherence
◦ health service use
from reported cognitions such as beliefs, expectations, health-related
locus of control or self-efficacy, and intentions.
Health Belief Model (Becker, 1974, 1988; Janz & Becker, 1984).
(diagram on page 28: Lecture 1)
Applications
◦ Genetic screening, cancer screening, smoking,
diet, exercise, adherence to diabetic regimens
and many more
◦ Quantitative reviews described in Conner &
Norman
◦ Barriers most reliable predictor of behaviour
followed by susceptibility and benefits, and
finally severity
◦ Effect sizes are small
Health Belief Model Limitations
◦ Interaction between variables not specified
◦ Static model (not staged or dynamic process)
◦ Little account of social influences
◦ May overemphasise threat

Cardiac Psychology: Overview and Outcomes
- Cardiovascular disease and coronary heart disease (CHD)
- Health behaviours: Development and progression of CHD
- Psychology and cardiac events
- Cardiac rehabilitation
Outcomes:
Describe coronary heart disease and explain cultural variability in coronary heart disease
Summarise the role of health behaviours and psychological factors in the development and progression of coronary heart diseases
Compare and contrast different forms of cardiac rehabilitation
Explain the role of psychology is assisting people after a cardiac event
Cardiovascular Diseases
- General heading - Several diseases that result from problems with the
heart and the circulatory system - Most common:
o Coronary Heart Disease
o Heart Failure
o Stroke
o Hypertension
Coronary Heart Disease: Arteriosclerosis
- Arteriosclerosis- any hardening of
the arteries, making them more
susceptible to blockages - Atherosclerosis – buildup of plaque
fat in and on artery walls that can
cause arteries to narrow, blocking
blood flow. The plaque can also burst,
leading to a blood clot.

Heart Disease: The Australian Figures
- In 2017-2018 – 1.2 million adults (6.2%) had 1 or > conditions related to
heart, stroke or vascular disease - CVD – Leading cause of death: 42,300 deaths (25%) in 2019
- Stroke – 38,600 events (100 per day) in 2018
- Heart attack or (angina) - 58,700 (161 per day) in 2018
*In 2019, 11.8 billion for CVD, with 2.4 billon for CHD - 2017-2018 - An estimated 580,000 Australians aged 18+ (3.1% of the
adult population) had CHD at some time - 430,000 had a heart attack or other CHD
- In 2018, 65% of acute coronary events occurred in males
- CHD and acute coronary events are more common with increasing age
