“Your First Step to Change” is an online guide for individuals thinking about changing their gambling behavior. Developed by Harvard Medical School’s Division on Addictions and the Massachusetts Council on Compulsive Gambling with support from the Massachusetts Department of Public Health and the National Center for Responsible Gaming, this interactive self-guided program was originally developed as a booklet in 2002 for callers to the Massachusetts Council’s helpline. The gambling version of “Your First Step to Change” is the first of several self-guided programs that is available on the BASIS Web site.
