This 24-item rating scale measures the severity of drinking problems, differentiating between alcohol use considered to be normal in adolescent development and alcohol use that is not considered to be normal. ADI items focus on the problems that arise from alcohol use, not on the amount or the frequency of consumption. ADI items were selected to represent the four domains of problem drinking indicators: loss of control of drinking, social indicators, psychological indicators and physical indicators.
The ADI can be administered to individuals or groups by counsellors, teachers, or others who work with adolescents. Adolescents with 10-11 year old reading skills can complete the ADI, and scoring is quick and easy.
