Project TAMMI is a research study that tests whether different types of text messages and assessments are helpful to people who want to cut down on their drinking. These text messages are based on studies that have been shown to help people reduce their drinking in the short-term, but we are examining the effects over time. Individuals who enroll will be randomly assigned to one of three groups which vary in the amount and type of messages. This project is being conducted through the Partnership for Drug-Free Kids and the Feinstein Institute for Medical Research at Northwell Health, and is sponsored by the National Institute on Alcohol Abuse and Alcoholism (NIAAA).
