Mobile Alcohol Response Study (MARS)

Picture
MARS examines participants' alcohol use, drinking-related experiences, and effects of alcohol on mood and behavior. Participants complete brief assessments on their smartphone during two typical episodes (one alcohol-drinking episode and one non-alcohol drinking episode) in their natural environment (for example, at home, friends' houses, bars or restaurants, outdoors, etc.).

Study participation is usually completed within one week.

Currently, we are not recruiting for this study. But we will be enrolling participants in Summer/Fall 2023. Please check back for details later or contact Daniel Fridberg, Ph.D.
