Smartphone-paired Breathalyzers and Loss- and Gain-framed Texts for Reducing Drinking and Driving

The overall objective of this project is to leverage smartphone-paired breathalyzers to implement cost-effective and scalable behavioral interventions to reduce risky drinking behaviors such as drinking and driving. Prospect theory proposes that messages framed in different ways can elicit different responses from individuals. Loss aversion refers to people's tendency to prefer avoiding losses to acquiring equivalent gains: it's better to not lose $5 than to find $5. People are more motivated to avoid losing something than they are to win something. Studies have found that delivering messaging framed as a loss are also effective in motivating certain behaviors. On the other hand, gain-framed messages have been shown to have a positive effect on preventative healthcare. By using automated remote monitoring, innovative loss aversion and gain-framed messaging strategies incorporating insights from behavioral economics could be more easily implemented by delivering effective messaging prior to a risky behavior taking place. The investigators hope that the use of loss aversive and/or gain-framed messaging will lead to individuals improving planning behavior around drinking, especially in regards to drinking and driving. The objective of this project is to demonstrate the feasibility of a scalable intervention using loss- gain-framed messaging to reduce drinking and driving, compare the effectiveness of each type of messaging, and to increase the use of Blood Alcohol Content (BAC) monitors as a way to plan safer strategies when drinking. The investigators' long-term objective is to secure federal funding for research that leverages insights from behavioral economics supported by smartphone technology to reduce risky drinking.
