method is a widely accepted tool to collect detailed and reliable self-reported exposure (29, 34).
We measured alcohol use with a self-report questionnaire based on the TLFB
. Participants were required to indicate how much alcohol they had consumed during the last month, using a 9-point Likert scale ranging from 0 = none to 8 = almost every day.
In previous studies, a modified version of the TLFB
called the Impaired Driving Assessment has shown high estimates of reliability delivered face-to-face or over the Internet (Usdan, Schumacher, & Bernhardt, 2004; Usdan, Schumacher, McNamara, & Bellis, 2002).
The ARAQ total score was also signifi- cantly correlated with the BP total score [N=209, r =0.25, p Less than 0.0005 (one -tailed)], the AUDIT [N=209, r =0.539, p Less than 0.0005 (one-tailed)], the TLFB
[N=209, r =.139 p Less than 0.04 (one-tailed)], and BIS total [N=209, r =.247, p Less than 0.0005 (one-tailed).

The DDI and TLFB
were employed as comparative measures for Part A of the ADOM, whilst the TOP and SF-36 questions were employed as comparative measures for Part B.
Se empleo la Entrevista Diagnostica Internacional Compuesta (CIDI) y la Escala de Valoracion de Wender Utah para las entrevistas de tamizaje y la obtencion de datos demograficos, y el Indice de Intensidad de la Adiccion (ASI), la Linea Cronologica Retrospectiva (TLFB
), la Escala de Abandono de la Marihuana, la Escala de Problemas por Marihuana y la lista de comprobacion para la dependencia de la marihuana del Manual Diagnostico y Estadistico de Trastornos Mentales (DSM-III-R).

Concretamente, en el caso de la "cantidad de consumo por ocasion", medida a traves de Linea Base Retrospectiva" (TLFB
; Sobell & Sobell, 1992), se reportaron los siguientes datos al compararse la linea base con el tratamiento (7,7 vs.
The timeline follow-back (TLFB
; Sobell & Sobell, 1992) method was used to assess both the use/nonuse of alcohol (to include the number of standard drinks of alcohol consumed per drinking day) and seven other drugs (powder cocaine and crack cocaine, marijuana, heroin, amphetamines, benzodiazepines, hallucinogens, and barbiturates).
One of the instruments that has been used for research purposes and can be applied in clinical settings is the Timeline Follow Back (TLFB
; Sobell & Sobell, 1992).
The alcohol time-line follow-back (TLFB
) (Sobell and Sobell, 1995b) is a drinking assessment method that obtains estimates of daily drinking and has been evaluated especially with clinical populations.
