Applicable Populations: The assessment is designed for use with individuals between the ages of 18 and 73 (SASSI, 2001). Validity and Reliability: The assessment has an overall reliability coefficient of 0.93 based on test-retest reliability, making it an extremely reliable assessment (Fredricks, 2010). For its validity rate, the assessment has an overall validity of 93.9% (Fredricks, 2010). However, many argue that this reliability and validity should be accepted with caution. Test-retest reliability is limited by the fact that it is only reported over a two-week period. Furthermore, the sample population with a high incidence of substance abuse disorder may attribute a high rate of validity to it (Fredricks, 2010). Malingering and Deception: This tool contains a validity scale, aimed at identifying random response patterns. It has also been noted for its effectiveness in identifying individuals who deny or try to hide their substance abuse problems (SASSI,
