Changing Eating Behaviour: Assumptions
• It is just common sense
• Knowledge and information drive eating behaviour
• People act irrationally
Changing Eating Behaviour: Process
Eating Behaviour
change
What?
Why?
How?
Where?
Changing Eating Behaviour: What?
• Step 1: Specify the target behaviour
-TACT principle
T: Target?
A: Action?
C: Context
T: Time? th
Overweight adults
Controlling portion sizes
At work canteen
During lunch time
• Step 2: Define the eating behaviour problem
Changing Eating Behaviour: What?
Stok et al., 2017. PLoS ONE12(2): e0171077
Changing Eating Behaviour: Why?
• Step 2: Define the eating behaviour problem
Changing Eating Behaviour: How?
• Step 3: Prioritise what needs to change
-APEAS principle
• Affordable
• Practical
• Effective
• Acceptable
• Safe
Changing Eating Behaviour: How?
“What works,
how well, for
whom, in what
setting and
why?”
Step 4: Select appropriate behaviour change techniques
• Use guidance from previous mapping exercises
• Engage with the end users (Person-based approach)
• What resources are available to implement BCTs?
• What modes of delivery are feasible within the local context?
Changing Eating Behaviour: How?
Step 4: Select appropriate behaviour change techniques (BCTs)
Case Study: Specify the target behaviour
•T: Target? Nurses
•A: Action? Healthy Eating
•C: Context Workplace
•T: Time? Working hours
Case Study: Define the eating behaviour problem
Case Study: Prioritise what needs to change
Case Study: Identify appropriate behaviour change techniques
Influencing Factor BCT (s)
Environmental context
and resources
5
Beliefs about
consequences 10
Emotion 3
Knowledge 4
Optimism 1
Behavioural regulation 1
1. Reduce negative emotions
2. Self-assessment of affective
consequences
3. Social support (emotional)
Case Study: Identify appropriate behaviour change techniques
Implications for stakeholders: Where?
• Commonsense approaches are frequently ineffective or counter-productive
• Knowledge and information not sole drivers of eating behaviour
• Only a first step
Practical take home tips
• Use an approach that is;
1. Specific: Enough about target eating behaviour
2. Comprehensive: Considered all factors that might influence eating behaviour
3. Evidence‐based: Understands BCTs that are acceptable and evidence-based in context
4. Flexible: Adapted and tailored to different eating behaviours and people
= Practical and Effective behaviour change
Panel Discussion
• Experiences people have had using BCTs to change behaviour?
• Issues I haven’t covered?
• Other approaches?
