 Pick a disorder or health condition that interests you (e.g. heart disease, diabetes, depression, obesity, etc.). Do some research into the condition and find a health intervention (i.e. some sort of attempt at changing behavior in a way that promotes good health) that has evidence to support it being used to prevent the occurrence of the disorder. Then, devise a health promotion effort that is based on one of the theories that could be used to convince a group of people to participate in the new healthy behavior.

Components:
1) Describe the condition and why it is a health threat.

2) Discuss the evidence supporting the behavior you wish to promote.

3) Outline your plan, based on the theory you select. Make sure you emphasize the ways in which your plan is designed specifically with the theory in mind.
