The Severity of Dependence Scale (SDS) is a 5-item self-administered questionnaire that provides a score indicating the severity of dependence on drugs.
The SDS was developed to provide a brief measure of the psychological aspects of dependence experienced by users of various types of illicit drugs. It is a measure of compulsive use and the individual's preoccupation and anxieties about their own drug taking, as well as feelings of impaired control over their drug use.
