Is a very brief web-based intervention with focus on protective behavioral strategies efficacious in reducing impaired control over alcohol in undergraduates?

Impaired control (i.e., difficulty adhering to limits on alcohol use) prospectively predicts self-reported alcohol-related problems in undergraduates yet remains understudied. In particular, there is little evidence regarding whether brief interventions can reduce impaired control. An efficacious, very brief, web-based intervention focused on protective behavioral strategy (PBS) use may be well suited to reducing impaired control, but there is also little evidence regarding relationships between impaired control and PBS use. Data were analyzed from a randomized controlled trial of U.S. Tertiary Health Research Intervention via Email (Leeman et al., 2016) that yielded evidence of reduced weekly and peak alcohol use among undergraduates who drink heavily (
