Brief description

The DEP-ADO was designed to identify the problematic use of alcohol and other drugs. It is made up of eight questions addressing frequency of use in the past 12 months, substance use in the past month, the age of initiation, injection drug use, number of five or more drinks in a single occasion in the past 30 days and last 12 months, the negative effects associated with substance abuse (six domains covered); and the frequency of cigarette use. It was developed in Quebec and was tested with a French-speaking population, although an English-language version is also available. The DEP-ADO was designed for frontline workers.
