Measure
Standard Treatment as Usual (TAU)
This is the regular treatment a participant would normally receive at the clinic and generally includes individual and/or group therapy sessions and regular urine monitoring. Sessions will generally last for 1 hour one time per week for 8 weeks and include issues such as teaching about the treatment program, teaching important ideas about recovery, increasing knowledge about specific problems participants may have with addiction and/or demonstrating new ways of coping with skills designed to fit their lifestyle. Participants will also be asked to complete a brief questionnaire and to provide urine and breath specimens for alcohol and drug testing once each week.
Individual Clinician-provided Cognitive Behavioral Therapy (CBT)
This is individual treatment provided by a trained Cognitive Behavioral Therapy (CBT) clinician who will focus on teaching skills to understand and change participants behaviors to help them avoid alcohol use. Sessions with the clinician will generally last for 1 hour one time per week for 8 weeks. Participants will also be asked to complete a brief questionnaire and to provide urine and breath specimens for alcohol and drug testing once each week. Individual clinician-provided CBT: Individual clinician-provided CBT
Computer Based Computer Based Training for Cognitive Behavioral Therapy (CBT4CBT)
In this treatment participants will work with a computerized program that teaches skills for stopping alcohol use and increasing coping skills, such as how to understand patterns of alcohol use, how to cope with cravings for alcohol, how to refuse offers of alcohol, and so on. The CBT4CBT program will cover the same skills as the individual clinician-provided CBT, only here it will be done by a computer. Participants will be taught how to use the computer program by a staff member and will be asked to spend about 8 hours using the program (approximately one hour per week) at the clinic.Participants will also be asked to complete a brief questionnaire and to provide urine and breath specimens for alcohol and drug testing once each week.

PRIMARY outcome

Timeframe: from end of treatment at week 8 up to 6 months

Population: Intention to treat process was used for data collection. All randomized participants were tracked and follow up data collection was attempted for the 6 months post treatment. Contact attempts were at 1 month, 3 month and 6 month post treatment. Analysis population numbers start at the number of randomized participants that completed the 1 month post treatment interview. Months 2 and 3 numbers reflex number of randomized participants that attended the 3 month post treatment interview and so on.

The Timeline Follow Back is a calendar-based questionnaire used to assess alcohol use-consumption variables and can be used to measure change over time. This outcome was updated upon results entry. Presented are the percent days abstinent from alcohol use summarized monthly.
