Substance Abuse Subtle Screening Inventory

SASSI Institute


A self-report screening instrument for substance dependency


The Substance Abuse Subtle Screening Inventory (SASSI-4) identifies high or low probability of substance use disorders and includes a prescription drug scale that identifies individuals likely to be abusing prescription medications.

Objective decision rules classify individuals as chemically dependent or as not chemically dependent. It is especially effective in identifying early-stage chemically dependent individuals who are either in denial or who are trying to conceal their chemical dependency. In addition to being used as a screening instrument, the SASSI-4 also provides clinical insights into a respondent’s defensiveness and willingness to acknowledge experienced consequences of substance use disorder.

New to the SASSI-4

  • A brief new scale, Prescription Drug (Rx), was added to accurately identify individuals likely to be abusing prescription medications
  • Validated to screen for multiple levels of Substance Use Disorder (SUD) severity: The SASSI-4 screens for SUD along the full DSM-5 continuum of severity: mild, moderate, and severe SUD
  • Distinguishes likely Substance Use Disorder from other psychological disorders: The SASSI-4 can accurately identify the presence and the absence of SUD, even when other psychological symptoms are present
  • Enhanced SUD identification through subtle items that have been added to the SASSI-4 SAT scale
  • Additional face valid items to identify symptoms represented in the DSM-5 diagnostic criteria
