Timeline Follow Back

The timeline follow back is a measure of drug and alcohol consumption in the prior 90 days. The timeline follow back is a calendar-based retrospective account of drug and alcohol consumption for a specified period of time (e.g., past 90 days). One of the most commonly reported metrics of drug and alcohol consumption from this measure is percent days abstinent (PDA). Percent days abstinent is simply the proportion of days for the specified period of time (e.g., 90 days) in which drugs or alcohol were not consumed. Percent days abstinent can range from 0 to 100 with 0 representing no abstinence during a specified period of time (i.e., consumed alcohol every day) and 100 representing complete abstinence during a specified period of time.
