Approaches to specifying a target behaviour

How do you specify a target behaviour. Here are two models, the behaviour wheel and AACTT

The authors of the Behaviour Change Wheel process recommend that a target behaviour is specified in terms of:

  • Who needs to perform the behaviour?
  • What does the person need to do differently to achieve the desired change?
  • When will they do it?
  • Where will they do it?
  • How often will they do it?
  • With whom will they do it?

Other approaches can also be used to do this, such as the Action, Actor, Context, Target, Time (AACTT): a framework for specifying behaviour. The AACTT framework can be useful when exploring complex behavioural problems that involve sequences of behaviours performed by different people.
