Follow-up of abstinent and nonabstinent alcoholics.

Despite differences in samples and designs, follow-up studies of alcoholic patients by the Rand Corporation, the state of Oklahoma, and the Veterans Administration (VA) revealed more similarities than differences in outcome and relapse. In the VA study at 6, 12, and 24 months' follow-up, it was found that drinking status and psychosocial adjustment were significantly correlated, the percentage of patients drinking moderately varied from 33% to 47% and did not decrease over time, and the percentage of patients in remission remained constant at 55% over the 2-year period. These data appear to support the inclusion of moderate drinking in the definition of remission.
