Additional notes

In the working table of content for script writers there was an additional column entitled ‘message number’ – this way we were able to add the message numbers that addressed the individual barriers and enablers – allowing us to track the messages and ensure all the barriers and enablers were addressed.

In the final column of this table ‘behaviour change technique’ some additional information explaining how the BCT can be approached is occasionally added – again there was more information in the original table.

The BCT ‘modelling behaviour’ refers to ‘demonstration of the behaviour’ in the BCT taxonomy.
