Abstract

When assessing areas of clinical pathology and substance abuse, clinicians are not always provided with critical background information needed to assess properly and diagnosis their clients. For various reasons, full disclosure is not forthcoming during the initial intake or assessment process. Inadequate knowledge will, in turn, affect treatment planning. Valid and reliable assessment instruments are an invaluable resource for extracting additional facts. This study investigated that criterion validity between the Millon Clinical Multiaxial Inventory-III (MCMI-III) and the Substance Abuse Subtle Screening Inventory-3 (SASSI-3), as well as attempted to replicate psychopathology subgroup clusters as noted in a study by McMahon, Malow, and Penedo (1998). Finally, the current study predicted that a portion of the relationship between the MCMI-III and the SASSI-3 could be explained by a relatively large canonical dimension. All predictions were successful.
