The Adolescent Substance Abuse Subtle Screening Inventory (SASSI-A2) is a psychological screening measure that helps identify individuals who have a high probability of having a substance use disorder (i.e., substance abuse and substance dependence). It should be used for adolescents between 12 and 18 years old. It is relatively easy to identify someone who has been abusing alcohol and other drugs for many years and has thereby suffered numerous clear consequences. However, it is not as easy to identify and adolescent in the early stages of the disorder when there are not a lot of obvious negative consequences. The SASSI-A2 has been found to be 94% accurate in identifying both substance dependence and substance abuse disorders.
