Severity of Drug Dependence Questionnaire (SDA) or (OSDQ)

 

If a person abuses more then one drug, then the questionnaire should be repeated for each substance.

 

The instrument consists of questions about recent drug use.

(1) use of the substance out of control

(2) anxiety over missing a dose

(3) worry about substance use

(4) desire to stop

(5) expected difficulty to stop
