Remarks on method for MMPI-Rorschach studies.

An impressionistic list of methodological considerations that may be of consequence in Minnesota Multiphasic Personality Inventory (MMPI)-Rorschach studies is presented. These include the potential effects of the multidimensionality of the basic clinical MMPI scales in comparison studies, issues of deception and response style in such studies, and the rote of theory in guiding the selection of variables in the search for MMPI-Rorschach correspondences. The recently established necessity of controls for the total number of Rorschach responses provides the basis for suggestions for further controls in MMPI-Rorschach studies, including those for level of distress and for the minimization/exaggeration of psychopathology. An effort is made to contrast these two instruments in terms borrowed from information theory as a way of illuminating their complementary aspects, and suggesting means by which each may contribute to an enhanced understanding of the other.

A comparison of the PAI and MMPI-2 as predictors of faking bad in college students.

Both the Minnesota Multiphasic Personality Inventory-2 (MMPI-2; Butcher et al., 2001) and Personality Assessment Inventory (PAI; Morey, 1991) offer a large set of scales devoted to the identification of response styles. This study directly compared the effectiveness of the 2 inventories as indicators of overreporting. The 2 measures were administered to 52 college students instructed to fake bad under conditions describing either a forensic (n = 24) or psychiatric (n = 28) setting as well as to 432 psychiatric patients. Results indicated that the MMPI-2 F - K index and Fp Scale were the best single indicators of a faking bad response style and that the MMPI-2 scales were the better indicators as a set. However, the PAI scales demonstrated a significant level of incremental validity over the MMPI-2 indicators in every analysis conducted. The findings suggest that either inventory offers an effective approach to the detection of overreporting, and administering both inventories can enhance the accuracy of prediction further.

MMPI correlates of poststroke neurobehavioral deficits.

MMPI profiles of 130 male veterans with cerebrovascular accidents were examined in relation to type and degree of neuropsychological deficit, hemispheric location of lesion, and time poststroke. Three neurobehavioral factors (Verbal, Visuospatial, Sensorimotor) were extracted from the Halstead-Reitan Battery and Wechsler Memory Scale. Canonical analyses revealed verbal impairment to be associated with greater openness in reporting emotional difficulties (Scale F) and limited social facility (Scale Hy). Sensorimotor deficits were associated with anxiety and distress (Pt) in patients with left hemisphere (LHD) but not right hemisphere damage (RHD). Although RHD and LHD patients had similar composite MMPI profiles, neuropsychological deficits in RHD were unrelated to MMPI scores. Time poststroke was independent of MMPI findings in both LHD and RHD samples.

A validity index for the MMPI-2.

There have been numerous methods developed for the detection of valid profiles on the Minnesota Multiphasic Personality Inventory (MMPI)-2. The current study examined a method of combining seven different validity scales of the MMPI-2 into a common weighted method in assessing malingering in chronic pain patients. The weighted method was able to correctly classify 100% of nonlitigants, using a cutoff score of > or =5. The findings of this study suggest that chronic pain patients in litigation produce a different profile on the MMPI-2 validity scales than do nonlitigants. In a group of knowledgeable actors (malingerers), 86% was correctly classified. The overall finding showed 100% specificity and 86% sensitivity. The findings support the need for multiple validity scales to be examined in determining a valid profile. The weighted validity scales method was robust enough to account for "emotional distress" and still identify invalid MMPI-2 performance.

MMPI-2 indices of psychological disturbance and attention and memory test performance in head injury.

A number of studies have investigated the relationship between psychological disturbance and neuropsychological (NP) test performance. The current study is a replication and extension of who found that MMPI-2 indices of psychological disturbance are related to performance on NP tests of attention and memory in psychiatric and head-injured patients. In a large sample (N=381) referred for evaluation after sustaining presumed head injury, we examined the relationship between MMPI-2 indices of psychological disturbance and measures of attention and memory from the Wechsler Memory Scale-Revised (WMS-R), Wechsler Adult Intelligence Scale-Revised (WAIS-R), California Verbal Learning Test (CVLT), and the Memory Assessment Scales (MAS). Although related to other domains, MMPI-2 variables were most consistently related to measures of attention and List Learning. Even when demographic variables, injury severity, and litigation status were controlled, MMPI-2 indices significantly predicted performance on six out of eight tests. However, the correspondence between similar indices on the WMS-R and MAS were relatively low, especially for Verbal Memory and Visual Reproduction. Further, litigation was significant in predicting only 2 of 8 attention and memory indices.

Assessing explanatory style in teenagers: adolescent norms for the MMPI Optimism-Pessimism Scale.

This article reports adolescent norms for the Optimism-Pessimism (PSM) scale of the Minnesota Multiphasic Personality Inventory (MMPI). The PSM scale measures explanatory style on a continuum from optimistic to pessimistic by using 298 MMPI items. It is based on Seligman's theory of explanatory style and was constructed by applying the Content Analysis of Verbatim Explanations (CAVE) technique to the MMPI item pool. The normative equations are based on a random sample of 624 normal boys and 691 normal girls ages 13 through 17 years. Reliability estimates of .94 demonstrate that the PSM scale can accurately assess explanatory style in adolescents. These norms may identify a personality factor associated with poorer physical and mental health and lower levels of achievement.

"Profile" analysis of the personality characteristics of child molesters using the MMPI-2.

Identification of child sexual molesters has been attempted for at least half a century without success. This is due, in part, to the heterogeneity of child molesters. Child sexual molesters were studied in three ways. First, a discriminant function analysis was conducted to evaluate how well the MMPI-2 would distinguish child molesters from controls. Hit rates of 81% and 88% were found for clinical scales alone and the clinical and supplemental scales, respectively. Second, a cluster analysis of MMPI-2 data identified four groups that resembled clusters found previously with the MMPI. Third, when followed in treatment, all subgroups achieved significant progress ratings and no significant difference in treatment progress was found between clusters.

MMPI-2 profiles of NGRI and civil patients.

Limited information is available comparing individuals found Not Guilty by Reason of Insanity (NGRI) to other psychiatric patients. This study examined the MMPI-2 profiles of 36 NGRIs and 35 civilly committed inpatients at 3 state psychiatric hospitals. The NGRI and civil patient groups differed in terms of race and gender with more minority individuals and fewer women in the NGRI group. Therefore, these demographic variables were used as covariates in a MANCOVA comparing the MMPI-2 validity and clinical scales for these 2 groups. NGRIs and civil inpatients produced significantly different mean MMPI-2 profiles, with NGRIs reporting less pathology overall compared to civil inpatients. Specifically, NGRIs had lower scores on scales F, 1, 2, 7, 8, and O and higher scores on scale K. Contrary to expectations, NGRIs and civil patients did not differ on scale 4, supplementary scale Re, and content scales ANG, CYN, and ASP, or Harris-Lingoes subscale Pd2. Overall, these results suggest that NGRI patients are functioning at a higher level than civil patients. These findings are considered in terms of previous results and potential selection bias. Implications for treatment and future research are also considered.

Repression-sensitization and MMPI correlates of retrospective reports of parental child-rearing behaviors.

Relationships were sought between college students' retrospective reports of parental behavior and their R-S scores and MMPI profiles. In general, reports of greater parental rejection and greater covert parental control were found to be associated significantly with higher R-S scores and higher scores on a number of MMPI scales as well as greater overall elevation of MMPI profiles. Implications for clinical history taking were noted, and caution was urged in consideration of an individual's reports of past events and relationships.

Factor analysis of the MMPI-STAI.

Since MMPI measures of anxiety do not differentiate situational from chronic anxiety, an attempt was made to factor analyze the MMPI-STAI scores of 311 psychiatric inpatients. Four factors emerged that were labeled Adjustment, Passivity, Somatic Concern and Anxiety Proneness. The results were compared with other MMPI factor-analytic studies. Evidence supported Welsh's A as a measure of chronic anxiety.

MMPI profile predictors for successful and expired open heart surgery patients.

A total of 31 patients (17 females, 14 males) who were scheduled for open heart surgery were administered an MMPI within 1 week prior to surgery. Of the 31 patients, 20 (13 females, 7 males) survived and 11 (4 females and 7 males) did not survive the operation. MMPI scale T-score comparisons were made within sex between survivors and nonsurvivors. Surviving and expired males did not differ on any MMPI scales, while expired females had much higher average scale 1 and 3 elevations than did their surviving counterparts (p less than .05). Subsequent comparisons of expired and surviving female patients with 1-3 profiles revealed that females with 1-3 profiles who expired had a higher average L scale T-score and a lower average scale 6 T-score (p less than .05). Cutting scores established to divide 1-3 female profiles into success and expired groups yielded two results: (1) an L scale T-score of 50 or above identified 100% of the expired females while it generated 40% false positives and no false negatives; and (2) a scale 6 T-score of 57 and below identified 100% of the expired females while it generated no false negatives and no false positives. These results are consistent with previous research and may be used to predict mortality for prospective female open heart surgery patients with implications for psychotherapeutic assistance prior to surgery to increase prospects for success.

Correspondence of the MMPI and Mini-Mult among female reformatory inmates.

Comparison of the MMPI and Mini-Mult scales yielded significant scale-by-scale correlations. However, the group means were different in 6 of the 11 possible scales, and there was a general tendency for the Mini-Mult to over-estimate MMPI scales. The Mini-Mult proved to be highly ineffective to detect MMPI invalid profiles. In addition, agreement on profile configurations or high points and degree of pathology as indicated by number of significant clinical scale elevations was very poor. The results of this investigation are similar to the findings of Rybolt and Lambert (1975), as well as those of Platt and Scura (1972), and lead one to recommend that the Mini-Mult not be employed as a clonical assessment instrument with incarcerated adult female populations. Its multiple deficits make clinical use hazardous.

Using the MMPI 168 with medical inpatients.

The potential utility of the MMPI 168 with two inpatient medical populations was explored in the present study. Correlations and clinically relevant comparisons suggested that the MMPI 168 predicted the standard MMPI with a high degree of accuracy.

An external criterion study of the MMPI validity indices.

Two hundred and twenty-eight veterans who requested either inpatient or outpatient treatment at a VA Hospital were administered an MMPI and a structured mental status examination (the CAPPS) to determine whether MMPI validity indicators would be useful in the prediction of dissimulation during a structured interview. Statistically significant relationships were found between both F and F-K and ratings of "fake bad" interview behavior. However, the authors point out that the rather small correlations discovered are of little practical utility in the prediction of dissimulation during structured interviews, especially when consideration is given to the amount of time and effort expended to administer and score the MMPI.

Role-played and hypnotically induced simulation of psychopathology on the MMPI.

The differential effects of role-played vs. hypnotically induced simulation of a paranoid syndrome on diagnostic and validity scales of the MMPI were tested with 30 female undergraduate Ss. Hypnotized Ss given the paranoid syndrome suggestion simulated the MMPI more accurately than did role-playing Ss. The F scale and Gough F-K index of dissimulation identified the role-playing group, but not the hypnosis with simulation suggestion group. It was concluded that further refinement of the validity scales of the MMPI is needed to improve their effectiveness in detecting deception on this test.

A retest of MMPI prediction of admission to a psychiatric hospital.

In a previous study, Jones, Kahn, and Langsley (1965) investigated the hypothesis that the MMPI would prove clinically useful in the prediction of admission to a psychiatric hospital. They found that the MMPI had negligible predictive validity for such an application. However, several methodological flaws left the conclusion of that study in doubt. This paper retested the hypothesis that the MMPI can be predictive of the admission decision when a sophisticated multivariate classification technique and adequate sample size are used. Given our results, the hypothesis again must be rejected. Possible problems associated with testing an hypothesis such as this are discussed.

Validity of the MMPI 168 on private clinic subpopulations.

The diagnostic efficiency of the MMPI 168 and the standard MMPI was compared on three private psychiatric subpopulations: a hospitalized adult inpatient sample, a hospitalized adolescent inpatient sample, and an outpatient sample composed of vocational rehabilitation referrals. The MMPI 168 was found to be a viable alternative to the standard Form R on all three groups by separating invalid from valid profiles, normal from abnormal profiles, and by differentiating among neurotic, psychotic, characterological, and indeterminate profiles.

The MMPI as a predictor of response to conservative treatment for low back pain.

Studies that used the MMPI to predict the response of chronic low back pain patients to standard medical treatment have not produced definitive results. Patients seen in a university hospital orthopedic back pain clinic were given the MMPI before treatment, and 6 to 12 months later 76 patients completed follow-up forms that indicated their level of intensity during the previous week and their ratings of the success of treatment in relieving their pain as well as in enabling them to return to normal activities. Predictions of poor response were made in terms of either single MMPI scales or code types. Patients with poor outcome on two of the three criteria (level of pain intensity and ability to return to normal activities) had significantly higher scores on the Hs scale. The predicted high risk code types very accurately identified patients with poor response on the same two criteria; however, the code-type procedure overpredicted poor response in the good outcome group.
