AABM Training
Alcohol Approach Bias Modification (AABM) training is a computer training program that participants interact with by pushing and pulling a joystick. Participants are asked to respond to the format of a presented picture, irrespective of the pictures' content. Training effect is achieved by presenting alcohol pictures in push format only and non-alcoholic drinks in pull format only. AABM training consists of 3 sessions per week over 2 weeks, for a total of 6 sessions. Alcohol Approach Bias Modification: Computerized training

PRIMARY outcome

Timeframe: 12 months

Population: The analysis population consists of the target number (12) of participants that the investigators hoped to recruit and start on study treatment over a 12-month period. There appears to be an inconsistency only because the actual number of participants recruited and started on study treatment over the 12-month period was only 3.

The number of participants who enrolled and actually started study treatment over the 12-month recruitment period.

PRIMARY outcome

Timeframe: 6 weeks

Retention feasibility as measured by the percentage of participants completing Alcohol Drinking Paradigm (ADP) sessions 1 and 2 and completing the 2-week course of 6 AABM training sessions.

SECONDARY outcome

Timeframe: 6 weeks

Population: One participant did not complete the either ADP session.

Alcohol craving will be measured during ADP sessions 1 and 2 using the Alcohol Urge Questionnaire (AUQ). Alcohol craving will be measured during Alcohol Drinking Paradigm (ADP) sessions 1 and 2, using the total score of the Alcohol Urge Questionnaire (AUQ). The AUQ has 8 items. Each item is scored on a 1 to 7 scale (Strongly Disagree = 1 and Strongly Agree = 7; items 2 and 7 are reverse scored). Higher scores reflect greater craving. Total score range is from a minimum of 8 to a maximum of 56. The AUQ is administered before alcohol administration and at various times after alcohol administration. The AUQ score reported here is the highest AUQ score obtained for that ADP session.

SECONDARY outcome

Timeframe: 2 days (1 day each for ADP session 1 and 2)

Population: One participant did not complete the either ADP session.

Alcohol consumption will be measured during ADP sessions 1 and 2 using the number of alcoholic standard drinks consumed during ADP session 1 (before 2 weeks of AABM training) and ADP session 2 (after the 2 weeks of AABM training). Consumption was measured using the number of alcoholic standard drinks consumed during the ADP sessions. A standard drink per NIAAA definition is 14 grams of pure alcohol.
