An Overview of Internet- and Smartphone-Delivered Interventions for Alcohol and Substance Use Disorders

Substance use disorders are a serious public health concern that affect approximately one in 12 individuals 12 years and older. Despite the high need for effective treatments for substance use disorders, the underutilization of services is well documented. One potential method of increasing access to care is through the use of technology. Treatment through the Internet or smartphone provides attractive solutions for those who are ambivalent to seeking treatment, because these treatments are easy to access from almost anywhere, self-paced, low commitment, and anonymous. The purpose of this review is to summarize the literature on Internet and smartphone interventions for substance use disorders that were developed on the basis of evidence-based treatments. The authors discuss these interventions within two broad categories: brief motivational or feedback-oriented interventions, which typically include one or two sessions, and longer interventions, which include multiple modules and are based on cognitive-behavior therapy, relapse prevention, contingency management, or a community reinforcement approach. These therapeutic adaptations through new technologies allow for increased access to substance use treatments and appear to yield overall positive results in adjusting norms about substance use, decreasing and ceasing substance use, and improving confidence to manage substance use.
