A recent Welsh video that addresses the dangers of texting while driving has become an internet phenomenon with over 7 million views to date. The video, which will be shown in schools in this fall, features a teenager texting while driving, resulting in a graphic car crash that kills her passengers.
The creators of the ad argue that in order to capture the attention of teenagers, it is necessary for the video to be shocking and violent. However, some critics are skeptical about whether the ad will actually reduce the behavior, especially in the long-term. Health and social psychological research has looked extensively at the efficacy of fear arousing messages when it comes to changing behaviors.
In a recent article, Cameron and Chan (2008) discuss what persuasive elements may help in promoting health behaviors. It is commonly assumed that messages that evoke fear will prompt action; however, many studies have shown that highly evocative messages may actually lead to avoidance and fail to change behavior. In the health communication field, they find that fear arousing messages can be effective but only when coupled with other factors. For instance, when joined with an implementation plan, these messages have a better chance of changing behavior. Moreover, imagery may be effective in persuasive messages but only to the extent that it can directly relate the threat to the recommended plan of action.
While the commercial may be successful in garnering attention, ongoing research brings into question how effective it will be in terms of permanently changing behavior.
