“I have no clue what I drunk last night” Using smartphone technology to compare in-vivo and retrospective recorded alcohol consumption

9 June 2014

Researchers: Rebecca L. Monk, Derek Heim, Alan Price (Edge Hill University)

Key findings
  • Real-time reporting of drinking suggests higher levels of consumption than self-reports based on recall
  • Recalled levels of consumption often involve a significant amount of guesswork
  • Research on alcohol consumption has often been over-reliant on retrospective self-reporting
  • Smartphone technology is a promising approach to more accurately measuring individual consumption
