Relationship between the MMPI subtle-obvious psychopathic deviate subscale and the Shipley Institute of Living Scale IQ.

Abstract

The present study was conducted to determine the relationship between the Minnesota Multiphasic Personality Inventory's (MMPI) subtle-Qbvious (S-O) subscale and the Shipley Institute of Living Scale IQ (Shipley). A total of 90 participants were used. These participants consisted of individuals who were convicted of driving under the influence of alcohol (DUI) and were subsequently court ordered for a substance abuse evaluation at a midwestern mental health center. As part of the evaluation process, they were administered the MMPI and the Shipley. The participants' test scores were recorded from individual established files. Three groups were established as levels of the independent variable; these included one in which Sand 0 scores were normal and not more than 10 points different, one in which S scores were high (I > 70) and the 0 scores were normal (I < 70), and a final group of participants whose 0 scores were high (I > 70) and S scores were normal (I < 70) . Intelligence quotient scores derived from the Shipley were used as the dependent variable.A one-way analysis of variance (ANOVA) was performed, resulting in no significance between the IQ's of the three S-O groups. This finding was not consistent with previous research done on IQ and s-o endorsement patterns.
