Web & Smartphone Apps Providing Personalized Feedback Can Help Hazardous Drinkers Substantially Reduce Their Alcohol
Newswise — Brief electronic intervention providing personalized feedback can help hazardous drinkers substantially reduce their drinking, according to a new study in Alcohol: Clinical & Experimental Research. After an eight-week intervention, young adults whose drinking was previously deemed “hazardous” had similar drinking patterns to those considered “non-harmful.
Investigators worked with data from 313 undergraduate students . The participants filled out surveys on demographics, alcohol use, anxiety, and depression and completed impulsivity-related cognitive tasks; a subset of 178 downloaded a smartphone app designed to track their drinking in real time over two weeks. Participants were categorized as hazardous or non-harmful drinkers and organized into three groups with similar levels of alcohol intake. Those in the Control group received no feedback.
Hazardous drinkers in the Alc and AlcCog groups reduced their drinking more than those in the Control group. The Alc hazardous drinkers cut their alcohol consumption by one-third ; the AlcCog group by slightly more . The non-harmful drinkers did not change their drinking behaviors.
