简要总结
The study is designed to develop and test a tailored adaptive text messaging/short message service (SMS) intervention for individuals interested in reducing their alcohol consumption.
According to the National Institute on Alcohol Abuse and Alcoholism, problem or risky drinking is defined as greater than 7 standard drinks per week for women and 14 standard drinks per week for men. Other groups have other criteria (e.g., 10 drinks for women and 14 for men per week). The Institute of Medicine reports that problem drinkers are those with mild-to-moderate problem severity who do not have physical dependence.
Heavy drinking individuals with non-abstinence goals rarely seek treatment for excessive alcohol use, and newer methods such as internet screening and mobile apps provide opportunities to engage and treat this difficult to reach population. There are now 96 mobile phone contracts for every 100 people on earth, making mobile interventions a highly viable method for extending care beyond traditional methods. Text messaging or short message service (SMS) is the most widely available mode of mobile communication and despite its simplicity, has been proven to be a reliable and effective method to induce behavior change across behavioral health targets, including problem drinking. However, large scale randomized controlled trials are needed to provide the necessary empirical evidence to validate SMS interventions and understand the mediators and moderators of outcome for help seeking heavy drinkers who are using or unable to attend in-person care.

The investigators recently completed an R34 study to develop the first automated tailored adaptive (TA) text messaging intervention for problem drinking (PD) adults (Muench et al. 2017). The study compared TA to different automated once a day static messaging including: tailored only messaging (TO), loss framed messaging (LF), gain frame messaging (GF), and weekly mobile assessment only (MA) over 12 weeks in 171 problem drinkers recruited on the internet across the US. All messaging groups outperformed MA on most drinking outcomes, and the TA group had the largest effect sizes on every drinking outcome, with an average weekly drink reduction of 9 standard drinks at week 12. Over an 8-month period, 1149 individuals across the country took the web-based screening survey, highlighting the demand for messaging in this population. Furthermore, 94.7% of participants (Ps) enrolled completed the end of messaging week 12 survey and 80% wanted to continue messaging following the pilot trial. There were no adverse events in this study.
