What are the
facilitators and
barriers to the
uptake of weight
management
services?
How can we
design the
built/ lived
environment
to influence
health-related
behaviours?
Typical questions from policy teams
What are the drivers
of the provision of
brief advice to
patients by healthcare
professionals?
4
Draws on insights from psychological research; primarily
behavioural economics and health psychology
Can be applied at the individual, professional, community or
population level
Used upstream and downstream in prevention and treatment
Central role of robust evaluation to demonstrate effectiveness
Small changes can have widespread impact
Previous behaviour is best predictor of future behaviour
– not intentions or beliefs

Behavioural ‘Definitions’
Behaviour is anything a person does
in response to internal or external events.
(Hobbs, Campbell, Hildon & Michie, 2011)
Behaviour should be differentiated from its
determinants (self-efficacy, emotion) and its
outcomes (quality of life, cholesterol level).
Traditional Theories of Behaviour
• The Health Belief Model – Becker (1974) Importance of beliefs, perceived benefits &
barriers to action, self-efficacy, stimulus/ cue to action. Limitations: focused on
conscious decision making and ignores habits.
• Social Learning Theory, Social Cognitive Theory – Bandura (1977) Importance of
social environment, modelling and self efficacy Limitations: emphasis on conscious
decision making and reflective processes
• Theory of Reasoned Action / Theory of Planned Behaviour – Ajzen (1985)
Limitation: assume people act in a rational way at all times, not all behaviour is
planned.
• Stages of Change Model / Transtheoretical Model – Prochaska and DiClemente
(1997) Limitation: assumes behaviour change occurs in a linear fashion, progression
through a series of stages.
Limitations:
• Effectiveness of predicting behaviour change
• Intention-behaviour gap
• Not addressing automatic motivation, habits and impulsive behaviour.
Public Health England - Behavioural Insights Masterclass Public Health England - Behavioural Insights Masterclass 7
“..this review suggests that intentional
control of behaviour is a great deal
more limited than previous meta-
analyses of correlational studies have
indicated”
Changing Behaviours: The limitations of changing minds
“Changing behaviour by changing
minds is unscaleable, increases
inequalities, not very effective”
(Professor Theresa Marteau)

Health Psychology
Health Psychology and Behaviour Change
• The science of human behaviour and experience
• Aims to:
• Promote and maintain health
• Enhance the well-being of those affected by illness
• Improve the health care system and support health
policy formation
• Understanding how people think, feel and learn
can help us understand and predict how they will
act
If we can UNDERSTAND human behaviour, it
gives us insight into how to CHANGE human
behaviour
At the heart of behaviour [change] is the
person…
Bio-Psycho-Social Model
(Engel,1977,1980)
Strength of Health
Psychology lies in the
application of theoretically-
driven, evidence-based
science
Behavioural Science
12
Importance of Theory • Key questions to ask when developing interventions
(individual, community or population based levels):
1. What things should be considered when trying to
understand and change behaviour? • What bio-psycho-social factors might be important?
2. What factors might influence uptake/engagement? • What barriers/ facilitators might influence behaviour?
• Must move away from ‘common sense’ models of
behaviour change and draw on theory
Imagine you wanted to change physical activity behaviour
in an obese population to reduce diabetes and CVD risk…
What would you need to consider?? Hold that thought…

Now imagine a population of

A more holistic model of
behaviour change – COM-B
Capability, motivation and opportunity all need to be present for a behaviour to occur
They all interact as part of a system
Motivation must be stronger towards the target behaviour than competing behaviours
(Michie et al., 2011)

Definition
Psychological
capability
Knowledge, psychological skills (such as planning, attention,
strength and stamina) to engage in the necessary mental
processes (interpersonal skills, memory, attention, decision
processes).
Physical capability Physical skills, strength or stamina
Reflective motivation Active thought processes – attitudes and beliefs about what is
good or bad, the costs and benefits of doing something,
beliefs about consequences, goals, plans, and intentions.
Automatic motivation Less conscious thoughts processes that drive behaviour -
emotional reactions, desires (wants and needs), impulses,
drive states, habits, reinforcement, associative learning and
reflex responses.
Social opportunity Opportunity afforded by the social environment, social cues
and cultural norms, social acceptability and expectations.
Physical opportunity Opportunity afforded by the environment involving time,
resources, locations, cues.

Behavioural Economics
Standard Economic Theory
• Consistently rational
(not emotional)
• Self-interested (not
altruistic)
• Utility maximisers
(the greatest amount
of value possible for
the budget)
• Takes the optimal
route to achieve
goals
• Subject to biases
• Subject to irrationalities
• Use heuristics (shortcuts) to
make decisions
• Context and time
dependent
(inconsistent)
• Emotional
‘Homo-economicus’ In reality

thumb to aid in problem solving

How can Behavioural Science be Utilised?
21
Defaults We tend to ‘go with the flow’ of
a pre-set option
Salience Our attention is draw to what
is novel and appears relevant
to us
Substitution Easier to substitute a
behaviour than eliminate an
entrenched one

What can it do for you?
Help to achieve local and national public health outcomes
Provide theoretically-driven, evidence-based programmes
Provide low cost ways of enhancing existing systems or
processes
Improve the effectiveness of delivery and outcomes of
training
Provide rigorous, scientifically led evaluations
