4 key health protective behaviours

1. Not smoking.

2. Exercise/ Physical activity 30 mins a day.

3. 1-14 units of alcohol a week.

4. 5+ serving of fruits and veg a day.


Screening behaviours

Screening for certain conditions can help catch diseases earlier and implement treatment more effectively:

Hypertension screening

Blood cholesterol

Cancer screens

Cervical smear



Examples of health protective behaviours





Examples of risk behaviours


Alcohol consumption

Recreational drug use

Unsafe sex

Risky driving


The magnitude of the benefits of engaging in all health behaviours rather than one.

In all causes of disease, engaging in all 4 behaviours rather than none decreases risk by x3.5.

In other causes of disease that isn't CVS or cancer, this risk is reduced by almost x7.


The significance of the observed does-response effect

By choosing to undertake 1 key health protective behaviour, this decreases the risk significantly in all causes of disease.

So by choosing to not undertake one behaviour, risk is increased at least by around 0.5x.


Biopsychosocial health promotion techniques

Involves the promotion and evaluation of 'healthy' lifestyle programmes:
Health-protective behaviours
Health risk behaviors

Early identification of people at higher rish

Legislative action and government initiates.


IMB model

Psychological model for health behaviour.

States that there are three key elements needed to influence behavioural change:

Behavioural skills

Each component can be applied to other health behaviour theories: Transtheoretical, TPB and HBM.



Health belief model for health behaviour.

Model states that behavioural change is more likely to happen if individuals think they are more likely to get a disease/ condition:

Perceived severity and susceptibility- motivation for behavioural change, that comes with received information.

Individuals also weight the cost and benefits of changing their behaviour- perceived costs and benefits.
This influences their motivation to change their behaviour.

Cues to action remind individuals of perceived benefits, increasing motivation.

Individuals also need self-efficacy, a behavioural skill, to ensure behavioural change.


Theory of planned behaviour

The main factor that causes behavioural change is the change in intention of the individual- i.e for an individual to stop smoking, they must genuinely intend to do so.

Intention is influenced by:
- The attitude of the individual

- The subjective norm around the behaviour. This is what an individual perceives others to think of a certain behaviour

- Behavioural control (behaviour skill)


Limitations of the models: TPB, HBM

They are linear:
They assume that the changing certain factors will definitely change behaviour

Doesn't account for the fact that some may relapse in behaviour.
The models explain why one may undergo behavioural change but doesn't explain why one may not continue


Transtheoretical model

Health behaviour model that considers relapse- where change in behaviour is not continued.


1. Precontemplation- individual does not know behaviour risk has negative effect.

2. Contemplation- Individual receives information in a convincing way that allows them to consider negative effects of their behaviour.

3. Preparation- Individual has decided to change behaviour and plans how to do so.

4. Action- Behavioural change is undertaken.

5 Maintenance- Behavioural change is maintained

Relapse can occur at steps 2-4, going back to contemplation or preparation.


SMART goals

A method of getting people to change their behaviour by setting an efficient goal.



Motivational interviewing

1 on 1 interviews that helps people initiate and sustain changed:

Enhances motivation and commitment to change

Addresses barriers to change

Overcomes ambivalence about behaviour change


Psychological factors that change unhealthy behaviour

Interventions with high-risk individuals

Interventions for a population

Cultural change- can be influenced by changes in legislations


Social factors that change unhealthy behaviour


Infrastructure/ resources


Limitations of health behaviour models

Much of the variance in the models are not explained

Probabilistic- doesn't explain exceptions

Does not address maintaining change

They can over exaggerate rationalising


Dual process model

Health behaviour model that states that health related behaviours are influenced mainly by:

Reflective precursors- reasoned actions, planned behaviour, health beliefs and restraint standards.

And Impulsive precursors: automatic affective reactions, automatic approach-avoidance reactions.

Boundary conditions can influence both precursors:
Habitualness, ego depletion, mood, cognitive load, drugs, working memory capacity.
