Applicable Populations: The assessment is designed for use with individuals aged 18 to 73 years (SASSI, 2001). Validity and Reliability: The assessment has an overall reliability coefficient of 0.93 based on test-retest reliability, making it a highly reliable assessment (Fredricks, 2010). For its validity rate, the assessment has an overall validity of 93.9% (Fredricks, 2010). However, many believe that this reliability and validity must be accepted with caution. Test-retest reliability is limited by the fact that it is only reported over a two-week period. Additionally, the sample population with a high frequency of substance use disorders could be attributed to its high validity rate (Fredricks, 2010). Malingering and Deception: This instrument contains a validity scale aimed at identifying random response patterns. It has also been noted for its effectiveness in identifying individuals in denial or those attempting to hide their substance abuse problems (SASSI,
