The Alcohol Timeline Followback Method (TLFB) is a tool developed in 1970 by Linda Carter Sobell and Mark B. Sobell used to assess an individual's alcohol intake.
With the timeline summary, it provides a relatively accurate portrayal of one's drinking.
This assessment has been evaluated across several populations (e.g., adolescents, adults, alcohol abusers of varying severity, college students, male and female normal drinkers in the general population).
Also, this assessment can be completed on the computer, by an interviewer, or by pencil-and-paper.
