1 Effectively changing eating behaviour: a practical guide Dr Brian Power PhD RD FHEA University of Hertfordshire

2 Changing Eating Behaviour: Assumptions It is just common sense Knowledge and information drive eating behaviour People act irrationally

3 Changing Eating Behaviour: Process What? Where? Eating Behaviour change Why? How?

4 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

5 Changing Eating Behaviour: What? Step 2: Define the eating behaviour problem Stok et al., PLoS ONE12(2): e

6 Changing Eating Behaviour: Why? Step 2: Define the eating behaviour problem

7 Changing Eating Behaviour: How? Step 3: Prioritise what needs to change -APEAS principle Affordable Practical Effective Acceptable Safe

8 Changing Eating Behaviour: How? Step 4: Select appropriate behaviour change techniques What works, how well, for whom, in what setting and why?

9 Changing Eating Behaviour: How? Step 4: Select appropriate behaviour change techniques (BCTs) 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?

10 Case Study: Specify the target behaviour T: Target? A: Action? Nurses Healthy Eating C: Context Workplace T: Time? Working hours

11 Case Study: Define the eating behaviour problem

12 Case Study: Prioritise what needs to change

13 Case Study: Identify appropriate behaviour change techniques Influencing Factor Environmental context and resources BCT (s) 5 Beliefs about consequences 10 Emotion 3 Knowledge 4 Optimism 1 1. Reduce negative emotions 2. Self-assessment of affective consequences 3. Social support (emotional) Behavioural regulation 1

14 Case Study: Identify appropriate behaviour change techniques

15 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

16 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

17 Panel Discussion Experiences people have had using BCTs to change behaviour? Issues I haven t covered? Other approaches?
