This approach is proposed by Doug McKenzie-Mohr and it incorporates 4 basic steps:

1. Identifying benefits and barriers to an action
What are the affordances to the behaviour?
2. Develop strategy to advocate behaviour change
What factors (incentives, prompts, norms etc.)can be used for change? Similar to ABA, it focuses on external factors but puts more emphasis on the role of social support.3. Implementing strategy
4. Evaluate effectiveness of strategy
