Perfectionism and multiphasic personality inventory (MMPI) indices of personality disorder

The present research tested the hypothesis that personal and social aspects of the perfectionism construct are related differentially to indices of personality disorders. A sample of 90 psychiatric patients was examined with respect to their scores on the Multidimensional Perfectionism Scale (MPS) and the personality disorder subscales (PDS) of the Minnesota Multiphasic Personality Inventory. The MPS provides measures of self-oriented, other-oriented, and socially prescribed perfectionism, whereas the PDS assess levels of various personality disorder symptoms. Zero-order and partial correlations indicated that the perfectionism dimensions of the MPS were related to various subscales of the PDS and, perhaps more importantly, that the findings vary as a function of the perfectionism dimension in question. The results are discussed in terms of the importance of perfectionism in personality disorder symptom patterns.     

Failed back surgeries and minnesota multiphasic personality inventory (MMPI) profiles

MMPI profiles were evaluated for 105 prospective surgical patients who had previously undergone surgery or other procedures for treatment of back pain. Patients were classified into groups having undergone zero, one, two, three, or four or more previous surgeries. While all groups demonstrated a characteristicsomatogenic profile, none of the MMPI validity or clinical scales significantly differentiated the groups and there was no relationship between increased number of surgeries and MMPI scale characteristics. These results support the nonoptimistic prognostication of thesomatogenic MMPI profile for surgical intervention for back pain but show no clear relationship of MMPI profile characteristics to degree of experience of previously failed surgery.     

Interpretive dilemmas created by the minnesota multiphasic personality inventory 2 (MMPI-2)

While the new MMPI-2 has the potential to provide more and better clinically relevant information than its predecessor, its introduction also creates several important problems for clinicians and researchers. In particular, the new norms and the use of uniform (rather than linear) T-scores result in the same raw scores on the two tests yielding clinical profiles that can be quite different, both qualitatively and quantitatively. These differences can result in difficulty in MMPI-2 profile interpretation when the user is relying on MMPI interpretive strategies. This paper addresses these concerns and offers some temporary remedial strategies.     

Resolutions to interpretive dilemmas created by the minnesota multiphasic personality inventory 2 (MMPI-2): A reply to Strassberg

We discuss the interpretive dilemmas identified by Strassberg (1991) and propose to resolve these dilemmas by pointing out that some change has indeed been introduced in the MMPI-2 and that change is a necessary requisite for improvement. Changes in administration procedures used with the MMPI-2 normative sample should only improve the quality of the normative data; changes in the way T-scores were developed lead to minimal change in the profile but enable more accurate interpretation of differences between scales on an individual's profile; normative changes have a differential effect on the clinical scales and this is to be expected; and the problem of codetype congruence has been overestimated and overstated. We conclude that the change introduced in the MMPI-2 can only serve to improve the test.     

Personality disorder correspondence between the million behavioral health inventory (MBHI) and the minnesota multiphasic personality inventory (MMPI)

The MBHI and MMPI personality disorder scales were analyzed for convergent and discriminant validity. Correlational data demonstrated that six of the eight scales were significantly related, while the remaining two scales approached significance. Further analyses of these data, however, demonstrated that none of the scales correlated significantly better with its convergent scale compared to nonconvergent scales. The MBHI classified significantly more of the sample as personality disordered (93%) compared to the MMPI personality disorder scales (17%). Furthermore, the MBHI tended to describe the sample as falling within the Anxious cluster of personality disorders, whereas the MMPI described them within the Dramatic cluster. Single scale codetype correspondence was found to be 15%, while two-point concordance was 12.5%, indicating very low congruence between personality style codetypes. These two measures do not appear to be measuring the same personality style constructs.     

Cross-validation of a minnesota multiphasic personality inventory (MMPI) subscale for the assessment of combat-related post-traumatic stress disorder

We have examined the Minnesota Multiphasic Personality Inventory (MMPI) scores of 80 carefully diagnosed veterans with post-traumatic stress disorder (PTSD) in an attempt to cross-validate the PTSD subscale and three-point MMPI code of Keane, Malloy, and Fairbank (1984). In general, although we replicated Keane and co-workers'cutoff scores, our hit rates were slightly lower than those reported originally.This research was supported in part by NIMH Grant MH-37839 to Dr. Kolb.     

Relationship between the Millon Behavioral Health Inventory and the minnesota multiphasic personality inventory (MMPI) in low-back pain patients

The Millon Behavioral Health Inventory (MBHI) is being used with increasing frequency for the assessment of chronic pain, although there is a relative lack of evidence as to its utility, and prior studies have not examined low back pain. This investigation compared the MBHI to the MMPI in a sample of low-back pain patients and analyzed subgroups of pain patients based upon their MBHI responses. Subjects were 60 patients who had been admitted to outpatient multidisciplinary pain clinics of two Chicago-area hospitals. Patients completed both the MMPI and the MBHI and provided demographic information. Results of correlational analyses indicated strong relationships between the MBHI psychogenic attitude, psychosomatic correlate, and prognostic index scales and the validity scales of the MMPI. The MBHI Pain Treatment Responsivity scale (PP) correlated with 16 of the other 19 MBHI scales. PP did not demonstrate specificity with low back pain patients. The results of both the scale comparisons and the exploratory two-group cluster subgroup analysis support the notion that responses to the MBHI are largely affected by the respondent's tendency to deny psychopathology or to admit emotional distress.
