Self-change interventions have great potential to aid the many problem drinkers who do not seek formal treatment. Because self-change interventions circumvent some of the barriers associated with traditional treatment services, they may help reduce the harm associated with alcohol abuse among untreated individuals, whose number far exceeds that of the minority who ever access formal alcohol treatment programs. Self-change/self-help materials have the added advantage of being relatively inexpensive, increasing their potential for wide distribution and attendant public health impact. The Internet is one promising route for distributing such materials to a large segment of the population. Three-quarters of Canadians and Americans use the Internet, including a large number who seek health-related information on line. Drinking self-change websites abound on the Internet, but because none has been scientifically evaluated it is unknown whether such sites do more good than harm.
