Creative ways to measure prevention

PreventConnect.org

Last March, CALCASA held a series of trainings on measuring prevention.  During that training, consultant Patrick Lemmon gave this presentation on one strategy to evaluate behavioral intent after a presentation using qualitative and quantitative methods. In this presentation below, Patrick looks at an example of a bystander intervention program.  I really like this type approach as one part of how to evaluate prevention efforts. (I also like this idea since he developed it after one of my ideas.)

What do you think about this?  What other creative evaluation methods do you use?
