Previous research on alcohol interventions by mail or other bibliotherapy approaches have shown these delivery methods to be effective, but there are delays in providing timely support and feedback by mail unless these are used in conjunction with telephone support. Compounding this issue is a lack of health care professionals who routinely deliver effective interventions for alcohol misuse, especially in rural and remote areas. However, there remains a need to engage people with risky levels of drinking or low-level problems who are unwilling to or simply do not seek assistance through traditional health services or self-help groups. These interventions have demonstrated efficacy and informed the way in which services are delivered at primary care and specialist levels.

The size of the community-wide challenges posed by alcohol consumption has triggered a substantial body of research into brief, low-cost interventions. Tragically, young people are significantly affected, with 18 to 35 year olds having the highest peak consumption and the greatest risk of short-term harm. These disorders can negatively impact on social functioning and contribute to fatalities and injuries related to drinking and driving, reduced job performance and absenteeism, aggressive behavior, and family and other relationship conflicts. Alcohol is estimated to be responsible for 3.8% of deaths and 4.6% of disability-adjusted life years lost worldwide, costing more than 1% of the gross national product of middle-income countries. Alcohol use is related to a wide range of physical, mental, and social harms, with harmful use ranked as the fifth leading risk factor for premature death and disability in the world. The World Health Organization (WHO) has estimated that there are about 2 billion people worldwide who consume alcoholic beverages and 76.3 million with diagnosable alcohol use disorders.
