One limitation of the article discusses the student potentially scoring inaccurate data to make the behaviour change project appear more successful than it actually is.
This can be resolved by scoring students on the plan itself rather than solely on the outcomes of the plan. It can be avoided by introducing a buddy system, i.e. making the behaviour change project public knowledge to others so they can check in and remind you about the data or the accuracy of that data. This allows them to verify the accuracy and ensure the self-management plan is valid and based on true data.
