Retest Reliability of Self-Reported Daily Drinking: Form 90
Journal of Studies on Alcohol and Drugs
Volume 68, 2007 > Issue 4: July 2007 pp 615-618





Historically, drinking was described in terms of the binary state of drinking or abstinence. More recently, drinking is viewed as a dynamic process, a trajectory of multiple fluctuations between drinking and abstinence across time. Modeling that kind of dynamic requires measuring individuals' drinking longitudinally during extended periods at cadences that capture the oscillations.

Retrospective timeline followback instruments, such as the Form 90, capture self-reported drinking on a daily basis. However, prior reliability estimates were based on variables averaged across cadences of 30 days.

This study expands the evaluation of retest reliability to daily reports of drinking.

Study results indicate that self-report of daily drinking has excellent retest reliability. These results suggest that data collected with the Form 90 can be used to model drinking with cadences that capture daily fluctuations in drinking.
