The Behaviour Change Wheel: using psychology to encourage healthier and more sustainable choices

The Behaviour Change Wheel: using psychology to encourage healthier and more sustainable choices

In the context of the coronavirus pandemic, the UK government has sought advice from both nudge1 and Behaviour Change Wheel (BCW)2 specialists to encourage positive behaviour. But this theory isn’t just limited to government; the grocery retail industry could do more to employ both theories to guide their behaviour change policies too.

Nudge theory has already been applied to retail with great effect (see my previous piece on this here), and the BCW can be used to support this initiative, as well as being a successful independent strategy.

The Behaviour Change Wheel

The Behaviour Change Wheel is a framework designed to create a change in behaviour, such as encouraging customers to be healthier or more sustainable.

  1. The wheel is made up of 19 different behaviour change frameworks including nudge theory3. Unlike nudge, this can allow for financial incentives including price, promotion and loyalty programmes.
  2. The BCW provides a step by step guide as to how to change behaviour, and materials covering the following three stages4:

The process of the BCW5

Whilst this prescriptive process may lack creative flare, it does break the thought process into manageable stages. When used at the outset of a behaviour change process, it can easily become part of an overarching strategy.

  1. The BCW provides a flexible framework which can be applied:
    • To different contexts, from healthy diets6 and physical exercise7 to saving energy8. increasing recycling9 and digital10
    • From the beginning of a project or simply to look back and assess why a behaviour change failed11
    • To both qualitative and quantitative research contexts12
    • To individuals and large or small groups 5.
    • To one-off and repeated behaviours5
    • To assess the viability of a behaviour change through its APEASE criteria (Affordability, Practicability, Effectiveness and cost-effectiveness, Acceptability, Side-effects/safety, Equity)5

A closer look at the Wheel

At the BCW’s hub sits the COM-B Model (in green) which states that Capability, Opportunity and Motivation are needed to change Behaviour. Each component can be broken into two areas, for example motivation can be automatic (i.e. subconscious) or reflective (i.e. conscious).

The Behaviour Change Wheel13

Surrounding the COM-B model are the Intervention functions (in red) that can be used to create the behaviour change. The outer wheel (in grey) provides public policy categories that may be used to change behaviour.

Definitions for the intervention functions are outline in the table below:

Function Definition Real world example
Education Increasing knowledge or understanding Providing information to promote healthy eating
Persuasion Using communication to induce positive or negative feelings or stimulate action Using imagery to motivate increases in physical activity
Incentivisation Creating an expectation of reward Using prize draws to induce attempts to stop smoking
Coercion Creating an expectation of punishment or cost Raising the financial cost to reduce excessive alcohol consumption
Training Imparting skills Advanced driver training to increase safe driving
Restriction Using rules to reduce the opportunity to engage in the target behaviour (or to increase the target behaviour by reducing the opportunity to engage in competing behaviours) Prohibiting sales of solvents to people under 18 to reduce use for intoxication
Environmental restructuring Changing the physical or social context Providing on-screen prompts for GPs to ask about smoking behaviour
Modelling Providing an example for people to aspire to or imitate Using TV drama scenes involving safe-sex practices to increase condom use
Enablement Increasing means/reducing barriers to increase capability (beyond education and training) or opportunity (beyond environmental restructuring) Behavioural support for smoking cessation, medication for cognitive deficits, surgery to reduce obesity, prostheses to promote physical activity

Intervention function definition and examples4

The relationship between the components of the COM-B model can be summarised in figure 2 below:

The COM-B System13

A typical example to explain how these components work together, is the encouragement of cycling4. To own a bike would increase the Opportunity, to know how to cycle would increase the Capability. An increase in both the Opportunity and the Capability would increase the Motivation to cycle. In turn, this is more likely to lead to a behaviour change.

So how does this apply to retail?

 Applying the Behaviour Change Wheel to a commercial context undoubtedly needs adaptation. For example, it may be worth replacing or adding to the public policy categories (in grey). I’ve already touched on retail policies like price, promotion and loyalty programmes, but there are numerous others including:

  • Category management
  • The buying process (online, offline, pay as you scan, self-service checkouts)
  • Staff (particularly relevant to educating and training customers)
  • The physical store and ambience
  • In store media
  • Out of store media
  • Personalised offers (once again using customer loyalty as a vehicle for behaviour change)

The future of the BCW

The main advantage of the BCW is that it is an amalgamation of 19 frameworks, however this scale means there can be a risk of watering down these frameworks, like nudge theory. For this reason, it may be prudent to run the frameworks alongside each other.

It should not be forgotten that habit formation should remain the gold standard of any behaviour change. Whilst the Behaviour Change Wheel and nudge theories incorporate habit formation, its importance can easily be lost in the mix.

Retail need to find ways to support the ever-increasing emphasis on areas like health and sustainability. Therefore, it may only be a matter of time before the BCW and the COM-B model are spoken of as frequently as nudge theory.
