Smartphone-based high-resolution ecological momentary assessment (HR-EMA) can reliably and validly assess real-world alcohol consumption patterns and related outcomes. Using HR-EMA, we examined the rate of alcohol consumption and subjective alcohol responses in 237 young adult heavy drinkers during the first hour of a typical drinking episode in their natural environment. Findings show that frontloading is associated with enhanced pleasurable responses to alcohol (i.e. stimulation and reward), particularly at the beginning of a drinking session. This may contribute to the excessive alcohol intake and related problems that are characteristics of alcohol use disorder.
