Prior to launching the social campaign in 2018, we partnered with ‘Ōlelo Community Media to sponsor a new anti-vaping category in their popular youth video contest. We also presented an anti-vaping presentation to six Hawai‘i high schools and challenged their media classes to participate in the contest. SeaRider Productions helped the classes with some technical production to get them off and running. In addition to message testing in focus groups, our in-person presentations allowed us to see firsthand which messages youth responded to and which were less effective. This built-in message testing was invaluable as was having the youth script and produce their own video content. They know what messages are most likely to work with their peers.
