Chronicling the Use of Caffeinated Alcoholic Beverages in College Students

Researchers used a daily diary approach to investigate whether caffeinated alcoholic beverage (CAB) use is associated with a range of substance-related problems. The participants were 122 heavy-drinking college students who used CABs. They completed baseline questionnaires and up to 14 consecutive daily surveys about the previous night’s drinking behavior. Results indicated that CAB days were associated with heavier alcohol use, regardless of mixer type. Additionally, beyond the amount of alcohol consumed the previous night, CAB days were linked with more alcohol-related problems, but only when the mixer was an energy drink.

The study, “A Daily Diary Examination of Caffeine Mixed With Alcohol Among College Students,” is published in Health Psychology. The National Institute on Alcohol Abuse and Alcoholism and the National Institute on Drug Abuse supported this research effort.
