Randomized Trial of a Smartphone App Designed to Reduce Unhealthy Alcohol Consumption
Study Details
Study Description
Brief Summary
Smartphone apps targeting alcohol consumption are increasingly employed as a means to help people reduce their alcohol consumption. Recognizing this potential, there has been an explosion of app development for unhealthy alcohol use, as well as other health-related behaviours. This study will recruit people who consume alcohol in an unhealthy manner. Participants will be assigned by chance to one of two groups and will be contacted 6 months after consenting to the study to assess changes in their drinking. In addition, this study will help us understand which components of the smartphone app are important to use in order to promote reductions in alcohol consumption. An app with proven efficacy, made widely available and free-of-charge to Canadians, will provide a much needed option to help those in need to reduce their alcohol use.

Detailed Description
Unhealthy alcohol use is common and causes tremendous harm. Most people with unhealthy alcohol use will never seek formal alcohol treatment. As an alternative, smartphone apps have been developed as one means to provide help to people concerned about their alcohol use. While such apps are widely available, the large majority have little or no evidence base, and research has indicated that some may actually do more harm than good. An app with proven efficacy at reducing alcohol consumption is needed in order to capitalize on this opportunity to motivate the large number of people seeking assistance using this promising technology.
This study will recruit people who consume alcohol in an unhealthy manner. Participants will be assigned by chance to one of two groups to either receive access to: 1) the full app; or 2) a copy of the app where only the educational content is provided (as opposed to the full intervention content of the app). Participants will be contacted 6 months after consenting to the study to assess changes in their drinking. We predict that the full app will lead to larger reductions in drinking and a more sustained impact than the educational content only app. In addition, this study will help us understand which components of the smartphone app are important to use in order to promote reductions in alcohol consumption.
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: Smartphone app - full access A smartphone app containing 5 modules: 1) personalized feedback on alcohol use (containing normative feedback by age and sex for those located in the Canada), 2) self-monitoring and goal setting tool, 3) tool to choose a designated driver, 4) blood alcohol content (BAC) calculator, and 5) educational information on alcohol use and its consequences (i.e. "fact sheets"). |
Behavioral: SMAART Canada smartphone app

|
| Active Comparator: Smartphone App - education only A version of the Smartphone app containing only the module with the educational information on alcohol use and its consequences (i.e. "fact sheets"). |
