Smartphone-paired Breathalyzers and Loss- and Gain-framed Texts for Reducing Drinking and Driving
Completed · Not applicable
Conditions studied: Alcohol Drinking, Alcohol Intoxication, Alcohol Impairment, Drive, Driving Impaired, Driving Under the Influence, Behavior, Drinking
In brief
This project aims to demonstrate the feasibility of a scalable behavioral intervention using smartphone-paired breathalyzers and text message aimed at reducing drinking and driving among individuals who report heavy drinking. All participants receive a smartphone breathalyzer to provide feedback on their estimated blood alcohol level. The intervention compares loss- and gain-framed messages that make the consequences of drinking and driving more salient to standard messages not to drink and drive.
