Abstract

The article focuses on a study evaluating two app-based methods for measuring alcohol consumption: a drink-count logging app and a breathalyzer, compared to retrospective self-reporting (Timeline Followback, TLFB) and a biomarker (Phosphatidylethanol, PEth). Conducted by researchers at the Karolinska Institute with 110 alcohol-dependent adults, the study found that while TLFB identified more drinking days, the drink-counting app showed strong agreement with TLFB and correlated well with PEth levels, indicating its validity as a monitoring tool. In contrast, the breathalyzer data demonstrated weaker agreement, likely due to lower usage during drinking episodes. The findings suggest that drink-counting apps could be a reliable alternative for tracking alcohol use. [Extracted from the article]
