Diagnostic utility of the Minnesota multiphasic personality inventory-2 in patients diagnosed with psychogenic non-epileptic seizures in the Czech Republic

PurposeThe purpose of the present study is to examine the Minnesota Multiphasic Personality Inventory 2 (MMPI-2) scores of individuals diagnosed with psychogenic non-epileptic seizures (PNES) in a tertiary epilepsy center in the Czech Republic. MethodPatients (F:M 130:45; mean age 36.8 years; 12.7 years of education, frequency of seizures 0.37 per day, illness duration 5.75 years) were assessed while inpatients at the Epilepsy Center, Na Homolce Hospital, Prague. Patients underwent video-EEG testing and comprehensive neuropsychological testing and personality assessment which included the MMPI-2. ResultsElevated (+1.5SD) F and Back F (Fb) validity scales were observed along with elevated clinical scales Hypochondriasis (Hs), Depression (D), Hysteria (Hy), Psychasthenia (Pt), and Schizophrenia (Sc). Scores higher than 1 SD were found in Psychopathic Deviate (Pd), Paranoia (Pa), Hypomania (Ma) andSocial Introversion (Si) scales and on validity scales True Response Inconsistency Scale (TRIN) and Variable Response Inconsistency Scale (VRIN). ConclusionPatients diagnosed with PNES exhibit numerous elevations on the MMPI-2. Understanding the underlying psychological constructs of the patient with PNES more accurately improves predictive utility (for the presence of PNES) and allows the clinician to offer interventions that are more customized. Minnesota Multiphasic Personality Inventory results may be useful to exclude other possible diagnoses and to further determine the individual’s characteristics that may be helpful when tailoring treatment, including psychotherapy.

Development and validation of culture-specific Variable Response Inconsistency and True Response Inconsistency Scales for use with the Korean MMPI-2.

In response to the concern that Minnesota Multiphasic Personality Inventory-2 (MMPI-2; J. N. Butcher, W. Dahlstrom, J. R. Graham, A. Tellegen, & B. Kaemmer, 1989; J. N. Butcher et al., 2001) Variable Response Inconsistency (VRIN) and True Response Inconsistency (TRIN) score invalidity criteria recommended for use with American samples results in an excessive number of exclusions in Asian samples (F. M. Cheung, W. Z. Song, & J. X. Zhang, 1996), we examined the cross cultural equivalence of the original VRIN and TRIN scales, and developed and validated Korean-specific VRIN and TRIN scales with Korean adult normative, clinical, and college samples. Although the results from item pair correlation analyses suggested the superiority of the Korean VRIN and TRIN over the original VRIN and TRIN, the mean comparison results and classification accuracy statistics using data with varying degrees of randomly inserted true and/or false responses did not reveal a strong advantage of one version over the other. We present and discuss plausible causes of the findings.

Individual differences in eyewitness memory and suggestibility: examining relations between acquiescence, dissociation and resistance to misleading information

The purpose of this study was to investigate relations between acquiescence, dissociation, and resistance to misleading information. A total of 111 participants took part in a series of staged events and then completed both the Dissociative Experiences Scale (DES) and the Minnesota Multiphasic Personality Inventory (MMPI-2). The participants returned to the lab 1 week later and were questioned about the details of their experiences during the previous session. As predicted, acquiescence as measured by the True Response Inconsistency Scale (TRIN scale) of the MMPI-2 was found to be significantly related to errors on misleading questions and repeated questions, but was not related to errors on non-suggestive specific and open questions. Scoring on the DES was found not to be related to acquiescence as measured by the TRIN scale, or errors on misleading, specific, or repeated questions. However, pathological dissociation was found to be related to both errors on misleading questions and indiscriminant variable responding as measured by the Variable Response Inconsistency Scale (VRIN scale) of the MMPI-2. These findings add to our developing understanding of factors that contribute to suggestibility in the interrogative context.

Inconsistent item pair Variable Response Inconsistency (J-VRIN) and True Response Inconsistency (J-TRIN) scales were developed for the Jesness Inventory using 250 male and 250 female delinquents, ages 14-18, to detect the random and acquiescent sets. J-VRIN utility was assessed by comparing protocols of 262 male delinquents, ages 14-18, screened for probable randomness with matched-pair Minnesota Multiphasic Personality Inventory-Adolescent, with 500 all and part random computer-generated protocols. J-TRIN utility was assessed by comparing these protocols with 500 simulated acquiescent and nonacquiescent protocols. Specificities above .90 showed sensitivities up to .89 for J-VRIN and .85 and .62 for J-TRIN. Predictive power and overall effectiveness are reported for base rates of.20, .10, .067, and .05. Scales' relations to gender, race, age, and verbal fluency were investigated using an overlapping sample of 1,085 male and 356 female delinquents. Verbal fluency was the most salient.
