A Quantitative Inventory of Alcohol Disorders (QIAD): a severity scale for alcohol abuse.

The Quantitative Inventory of Alcohol Disorders (QIAD) was developed to meet the need in the field of alcoholism treatment for an accurate, easily administered diagnostic tool which can measure the severity of alcoholism. This inventory is designed to be administered both on initial contact and as a follow-up after a given period of treatment. In addition to clearly differentiating alcoholic from nonalcoholic populations, the QIAD also proved to be both reliable and valid in comparison to other currently used severity (DBI) and diagnostic (MAST, DRC, NCA) scales.
