Let's Do Addiction Recovery Together! (LDART) is a web-based intervention grounded in social cognitive theory that is designed to reduce hazardous alcohol use. It has three active ingredients: 1) daily recovery goal setting and tracking, 2) motivational video, audio, and written messages from individuals in recovery, and 3) information on several community-based recovery groups (e.g., mutual-help groups, recovery community centers) that provide free, publicly available meetings and activities. Participants receive a text message reminder each night to go to the website to complete the activities, and a text message reminder each morning of the goal they set for themselves, with the option to change it. It only takes a few minutes to use LDART each day over the 4-week intervention period.
This is a 20-page psychoeducational booklet created by the National Institute on Alcohol Abuse \& Alcoholism (NIAAA) called "Rethinking Drinking". It contains several suggestions, strategies and resources for helping people who want to reduce their alcohol use. Participants will be encouraged to access the booklet for a few minutes each night over the 4-week intervention period.
