Behavioral Self-Control Program for Windows: results of a controlled clinical trial.

Forty nonalcoholic heavy drinkers were randomly assigned to receive a computer-based version of behavioral self-control training either immediately after pretreatment assessment or after a 10-week waiting period. Results at each of 3 follow-ups strongly support the study hypotheses. Participants in the immediate treatment group significantly reduced their drinking relative to their pretreatment levels and relative to those in the delayed treatment condition at the initial follow-up, 10 weeks after the pretreatment assessment. The delayed group did not change their drinking behaviors during this period of time. However, they significantly reduced their drinking by the second follow-up conducted after they received training. At the 12-month follow-up, participants maintained the gains they had achieved during treatment. There were no interactions involving participant ethnicity or gender. Although use of other drugs was not specifically addressed, such use did not increase, and there was some evidence of a decline.
