Abstract
AbstractResearch and clinical applications of q-methodology, in which a set of descriptive statements are sorted into a forced, quasi-normal distribution, have recently been extended to validation of integrated interpretations of the Minnesota Multiphasic Personality Inventory-2nd Edition (MMPI-2). This study aimed to develop a q-set customized for individuals diagnosed with substance abuse or those within a substance abuse treatment setting. 229 q-items, covering 11 content areas, were written to cover both the content area of the MMPI-2 and the variables affecting substance abuse treatment outcome. On the basis of their reliability, measured by inter-rater total correlation and variance components, 98 items were selected for final testing. Scores on this final q-set showed acceptable levels of reliability when forced into both a quasi-normal and flat distribution, with pairwise inter-rater reliability estimates of .519 and .517, respectively. Results of the study suggest the new q-set might be better su...

Substance abuse and dependence have long been areas of intense research interest and concern because of their high incidence rates
This study reports on the development of a measure that can be used to evaluate the usefulness of the MMPI in substance abuse treatment settings
It is not surprising that many assessment tools have been designed for substance abuse or dependence, including the Substance Use Disorders Diagnostic Schedule (SUDDS; Harrison & Hoffmann, 1989) and the Michigan Alcoholism Screening Test (MAST; Selzer, 1971)
Summary
Substance abuse and dependence have long been areas of intense research interest and concern because of their high incidence rates. Marijuana was followed by pain reliever abuse or dependence (1.9 million people) and cocaine abuse or dependence (913,000 people) (SAMHSA, 2014) Given these statistics, it is not surprising that many assessment tools have been designed for substance abuse or dependence, including the Substance Use Disorders Diagnostic Schedule (SUDDS; Harrison & Hoffmann, 1989) and the Michigan Alcoholism Screening Test (MAST; Selzer, 1971). A measure used as part of a clinical assessment should be able to provide clinicians with enough information to create efficient and effective treatment plans (Hayes, Nelson, & Jarrett, 1987) Due to their more limited scope, instruments like the SUDDS and MAST, which are focused on the diagnosis of abuse or dependence and other related behaviors, might not be as suitable for providing information that pertains to treatment planning, as compared to a broader measure of psychopathology and personality, such as the Minnesota Multiphasic Personality Inventory-2nd Edition (MMPI-2; Butcher et al, 2001)
