Validity of the MMPI-2-RF (restructured form) L-r and K-r scales in detecting underreporting in clinical and nonclinical samples.

In the current investigation, the authors examined the validity of the L-r and K-r scales on the recently developed Minnesota Multiphasic Personality Inventory-2-Restructured Form (MMPI-2-RF; Y. S. Ben-Porath & A. Tellegen, in press) in measuring underreported response bias. Three archival samples previously collected for examining MMPI-2 validity scales were reanalyzed in 2 studies. In Study 1 L-r and K-r significantly differentiated 2 groups of participants (patients with schizophrenia and university students) who had been instructed to underreport on the MMPI-2 from participants who took the test under standard instructions. L-r and K-r also added incremental predictive variance to one another in differentiating these groups. In Study 2 a similar set of outcomes emerged through the use of a differential prevalence design in which L-r and K-r significantly differentiated a group of child custody litigants who were administered the MMPI-2 from university students taking the test under standard instructions.

Some models and mechanisms for explaining the impact of maternal and adolescent characteristics on adolescent stage of drug use.

Examined the impact of interrelationship models and interactive mechanisms involving maternal and adolescent variables on the adolescent's stage of drug use in 356 mothers and their youngsters (aged 13–18 yrs). Ss completed questionnaires assessing maternal personality attributes, mother–child relationship, adolescent personality attributes, and stage of drug use. Results indicate that domains (i.e., sets of related variables) of adolescent personality and mother–child relationship variables each had an independent impact on drug use. Thus, conventional adolescents with strong mutual attachments to mothers were at lower drug stages. The maternal personality domain had an indirect impact on drug use via the other 2 domains. A psychologically stable and conventional mother was associated with a positive mother–child relationship and conventionality in the adolescent, which led to lower drug stages. The interactive effects on drug stage of individual maternal and adolescent measures were also examined. Results show that the impact on drug use of maternal risk (drug-prone) and protective (non-drug prone) characteristics could be altered by certain adolescent traits.

On the Usefulness of Measures of Normal Personality for Clinical Assessment: Evidence of the Incremental Validity of the Revised NEO Personality Inventory.

As a means of examining the incremental validity of a normal personality measure in the prediction of selected Axis I and II diagnoses, 1,342 inpatient substance abusers completed the Revised NEO Personality Inventory (NEO-PI-R) and the Minnesota Multiphasic Personality Inventory-2 (MMPI-2) and were assessed with structured clinical interviews to determine diagnostic status. Results demonstrated that scores from the NEO-PI-R (a) were substantially related to the majority of diagnoses, accounting for between 8% and 26% of the variance in the diagnostic criteria; (b) explained an additional 3% to 8% of the variability beyond 28 selected MMPI-2 scale scores; (c) increased diagnostic classification an additional 7% to 23% beyond MMPI-2 scale scores; and (d) were significantly more useful when examined at the facet trait level than at the domain trait level. Implications for incorporating measures of normal personality into clinical assessment batteries are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

A perspective on developments in assessing psychopathology: A critical review of the MMPI and MMPI-2.

Many concerns have been raised about the MMPI, but the emphasis on continuity during its revision precluded addressing many of these problems in the new MMPI-2. In this review, problems with the MMPI and MMPI-2 are explicated in an effort to promote more informed use of this and other tests of psychopathology. Major theoretical concerns include the lack of a consistent measurement model, heterogeneous scale content, and suspect diagnostic criteria. Serious structural problems include the overlap among scales, lack of cross-validation of the scoring keys, inadequacy of measures of response styles, and suspect norms. Six minor problems and new issues for the MMPI-2 are also discussed. It is concluded that although the MMPI-2 is an improvement over the MMPI, both are suboptimal from the perspective of modern psychometric standards for the assessment of psychopathology.

Joint custody: Is it right for all children?

Examines joint custody (JC) judicially and psychologically as one of several options for children of divorce. Sole and split custody and JC are discussed in terms of the individual and mutual needs of all family members. Arguments for JC include maintenance of relationships that resemble the intact family, insurance that child support will be paid, and continuance of parental involvement and responsibilities. Arguments against JC include the likelihood that among people unable to agree within marriage, harmonious coparenting will not take place; the fact that the brunt of the arrangement falls on the child; and problems involved with abuse, kidnapping, primary physical residence, and remarriage. The role of the family psychologist is outlined. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Children's adjustment in joint and sole physical custody families.

Examined patterns of custody and their relationship to the behavioral-emotional and social adjustment of 93 children, ages 3–14, in divorcing families. Assessed children and their parents within 1 year after parents filed for divorce, and again 1 and 2 years later. Children in joint physical custody (38%) had more access to both parents and made slightly more transitions between parental homes. However, custody arrangements were not significantly related to child adjustment. Factors associated with child adjustment included number of children in the family, child age and gender, parental depression/anxiety at baseline, and parental conflict at 1-year follow-up. Thus, no evidence was found that joint physical custody arrangements are different from sole physical custody arrangements with regard to child adjustment postdivorce.

The Minnesota Multiphasic Personality Inventory–2 Restructured Form in National Guard soldiers screening positive for posttraumatic stress disorder and mild traumatic brain injury.

The Minnesota Multiphasic Personality Inventory–2 Restructured Form (MMPI-2 RF) was administered to 251 National Guard soldiers who had recently returned from deployment to Iraq. Soldiers were also administered questionnaires to identify posttraumatic stress disorder (PTSD) and mild traumatic brain injury (mTBI). On the basis of responses to the screening instruments, the National Guard soldiers who produced a valid MMPI-2 RF were classified into four groups: 21 soldiers who screened positive for PTSD only, 33 soldiers who screened positive for mTBI only, 9 soldiers who screened positive for both conditions, and 166 soldiers who did not screen positive for either condition. Results showed that the MMPI-2 RF was able to differentiate across the groups with the MMPI-2 RF specific problem scale Anxiety adding incrementally to MMPI-2 Restructured Clinical scales in predicting PTSD. Both MMPI-2 RC1 (Somatic Complaints) and MMPI-2 RF head pain complaints predicted mTBI screen but did not add incrementally to each other. Of note, all of the MMPI-2 RF validity scales associated with overreporting, including Symptom Validity—Revised (FBS-r), were not significantly elevated in the mTBI group. These findings support the use of the MMPI-2 RF in assessing PTSD in non–treatment-seeking veterans. This further suggests that a positive screen for mTBI alone is not associated with significant emotional disturbance. (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

Defensive responding on the MMPI-2 in family custody and access evaluations.

The objective of this study was to examine defensive underreporting on the Minnesota Multiphasic Personality Inventory-2 (MMPI-2) with a sample of parents involved in custody dispute litigation. With a composite score derived from 2 nontraditional validity indicators—the Wiggins Social Desirability scale (WSD) and the Superlative scale (S), which had previously been identified as the best predictors of fake-good responding, 74% of litigants were identified as underreporting compared with 52% identified using traditional Lie (L) and Correction (K) scale criterion. Litigants identified as underreporters whether using either the WSD-S criterion or the L-K criterion, had clinical scale profiles that were similar to those identified as nonunderreporters. The outcome of this study suggests that the WSD and S scales are perhaps more useful in the identification of defensive underreporting than the L and K scales.

Predominant MMPI-168 profile clusters in a rehabilitation medicine sample.

Conducted cluster analyses of the Minnesota Multiphasic Personality Inventory-168 (MMPI-168) profiles of 46 female and 74 male rehabilitation medicine inpatients (aged 18–75 yrs), using a minimum-variance method, and identified 4 clusters of patient similarities. Relationships were tested between cluster membership and gender, age of disability onset, time since onset, and diagnosis. The profile of mean MMPI-168 scores for the largest cluster, representing about one-half of the total sample, showed no clinical elevations on any scale. The remaining 3 clusters were characterized primarily by depression, somatic focusing, and personality disorganization, respectively. Discriminant analysis supported the differentiation among clusters in terms of MMPI-168 scores and suggested that ruminative worry and openness to identifying problems accounted for the majority of the differentiation. With the exception of the cluster characterized primarily by depression, the 3 remaining clusters seemed similar to profile types consistently found in research on chronic pain samples.

"Detection of overreported psychopathology with the MMPI-2 RF validity scales": Correction to Sellbom and Bagby (2010).

Reports an error in "Detection of overreported psychopathology with the MMPI-2 RF form validity scales" by Martin Sellbom and R. Michael Bagby (Psychological Assessment, 2010[Dec], Vol 22[4], 757-767). There was an error in the title. The title should have read “Detection of Overreported Psychopathology With the MMPI-2-RF Validity Scales.” (The following abstract of the original article appeared in record 2010-24850-001.) We examined the utility of the validity scales on the recently released Minnesota Multiphasic Personality Inventory–2 Restructured Form (MMPI-2 RF; Ben-Porath & Tellegen, 2008) to detect overreported psychopathology. This set of validity scales includes a newly developed scale and revised versions of the original MMPI-2 validity scales. We used an analogue, experimental simulation in which MMPI-2 RF responses (derived from archived MMPI-2 protocols) of undergraduate students instructed to overreport psychopathology (in either a coached or noncoached condition) were compared with those of psychiatric inpatients who completed the MMPI-2 under standardized instructions. The MMPI-2 RF validity scale Infrequent Psychopathology Responses best differentiated the simulation groups from the sample of patients, regardless of experimental condition. No other validity scale added consistent incremental predictive utility to Infrequent Psychopathology Responses in distinguishing the simulation groups from the sample of patients. Classification accuracy statistics confirmed the recommended cut scores in the MMPI-2 RF manual (Ben-Porath & Tellegen, 2008). (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

Effects of psychopathology and demographic characteristics on MMPI-2 scale scores

Using multiple linear regression analyses, we examined the effects of subject status for 6 demographic variables and the presence of psychopathology on variance in MMPI-2 scale scores. The analyses were designed to measure the incremental contribution of the demographic variables to scale variance beyond that explained by presence of psychopathology. Demographic variables were found to contribute little incremental variance for the validity and clinical scales, but did explain more than 10% of the score variance for 1 clinical scale, 2 content scales, and 5 supplemental scales. For these 8 scales, gender was most often the potent demographic variable and an expected influence. The results are discussed in light of the use of gender-based norms and in terms of other potential factors that might explain MMPI-2 scale score variance.     

MMPI-2 norms: Comparisons with a census-matched subsample.

Concern has been raised about the fact that the Minnesota Multiphasic Personality Inventory–2 (MMPI-2) restandardization sample does not accurately represent the U.S. population, especially with regard to education. The implications of these deviations from population estimates have not been investigated. The authors conducted validity, clinical, content, and supplementary scale comparisons between the restandardization sample and a current census-matched subsample. Results showed a meaningful (equal to three T scores) difference for only a single scale. For clinical purposes, it would not appear that deviations from U.S.-population demographic estimates in the MMPI-2 restandardization sample would have more meaningful effects than those posed by the reliability limits of the MMPI-2 scales themselves.

Methodological problems and issues in MMPI, MMPI-2, and MMPI-A research.

Personality questionnaires are among the most versatile and user-friendly approaches to personality assessment. This article focuses on methodological considerations in conducting research on the MMPI-2, the most widely used clinical personality instrument. The article addresses ways of identifying methodological problems in research and alerts researchers to potential pitfalls in conducting personality assessment research. The topics addressed include the following: methodological factors addressing the continuity of the MMPI-2 and the original MMPI; sample selection in MMPI-2 research; issues concerning test administration; the application of exclusionary criteria in developing research samples; methodological factors in processing, reporting, and analyzing data; developing and evaluating new MMPI-2 scales; and assessing test bias in personality research.

Computerized adaptive personality testing: A review and illustration with the MMPI-2 computerized adaptive version.

Computerized adaptive testing in personality assessment can improve efficiency by significantly reducing the number of items administered to answer an assessment question. Two approaches have been explored for adaptive testing in computerized personality assessment: item response theory and the countdown method. In this article, the authors review the literature on each and report the results of an investigation designed to explore the utility, in terms of item and time savings, and validity, in terms of correlations with external criterion measures, of an expanded countdown method-based research version of the Minnesota Multiphasic Personality Inventory-2 (MMPI-2), the MMPI-2 Computerized Adaptive Version (MMPI-2-CA). Participants were 433 undergraduate college students (170 men and 263 women). Results indicated considerable item savings and corresponding time savings for the adaptive testing modalities compared with a conventional computerized MMPI-2 administration. Furthermore, computerized adaptive administration yielded comparable results to computerized conventional administration of the MMPI-2 in terms of both test scores and their validity. Future directions for computerized adaptive personality testing are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Psychometric properties of the MMPI-2-RF Somatic Complaints (RC1) Scale.

The MMPI-2 Restructured Form (MMPI-2-RF; Tellegen & Ben-Porath, 2008) was designed to be psychometrically superior to its MMPI-2 counterpart. However, the test has yet to be extensively evaluated in diverse clinical settings. The purpose of this study was to examine the psychometric properties of the MMPI-2-RF Somatic Complaints (RC1) scale in a clinically relevant population. Participants were 399 patients diagnosed with either epilepsy or psychogenic nonepileptic seizures on the basis of video–electroencephalograph monitoring. The internal structure of the MMPI-2-RF was evaluated using taxometric, confirmatory factor analysis, and item response theory procedures. Data from 4 content-specific scales directly related to RC1 (Malaise, Gastrointestinal Complaints, Head Pain Complaints, and Neurological Complaints) indicated that the latent construct of somatization is a dimensional variable with a bifactor structure. However, consistent with the scale's construction, a unidimensional model also provided adequate fit. A 2-parameter logistic item response theory model better accounted for observed item responses than did 1- or 3-parameter models. Results suggest that the RC1 scale is most precise for T score estimates between 55 and 90. Overall, the scale appears to be well suited for the assessment of somatization.

Detecting random, partially random, and nonrandom Minnesota Multiphasic Personality Inventory-2 protocols.

The ability of the Minnesota Multiphasic Personality Inventory-2 (MMPI-2; J. N. Butcher et al., 2001) validity scales to detect random, partially random, and nonrandom MMPI-2 protocols was investigated. Investigations included the Variable Response Inconsistency scale (VRIN), F, several potentially useful new F and VRIN subscales, and Fb - F ≥ 30 and Fb ≥ 90. Protocols completed by 150 adults participating in custody evaluations at a juvenile court setting, screened for randomness with a matched-pair Millon Clinical Multiaxial Inventory-III (T. Millon, R. Davis, & C. Millon, 1997), were compared with 500 computer-generated all-random protocols and with three levels of partially random protocols. VRIN was the most effective scale in detecting uninterpretable random protocols; however, VRIN ≥ 80 failed to identify 37% of them. Fb - F ≥ 30 and Fb ≥ 90 misidentified 41% of the 50%-65% random protocols as partially interpretable. Using the new scales, a decision algorithm was described that correctly classified 97%-100% of the protocols as interpretable, partially interpretable, or uninterpretable.

"Custody evaluation practices: A survey of experienced professionals (revisited)": Notice of clarification to Ackerman and Ackerman (1997) article.

Explains that the original article by M. J. Ackerman and M. C. Ackerman (Professional Psychology: Research and Practice, 1997[Apr], Vol 28[2], 137–145) was based on the same dataset and presented the same data as that in Ackerman and Ackerman (Family Law Quarterly, 1996, Vol 30, 565–586). Although highly similar wording was used, the authors used different formats to reach different audiences, but cross-references between papers were omitted. (The following abstract of this article originally appeared in record 1997-03377-007.) W. G. Keilin and L. J. Bloom (1986) explored 70 issues related to child custody evaluation practices. The current study replicates Keilin and Bloom's study and looks at an additional 42 items. Two hundred and one psychologists from 39 states were surveyed about 112 aspects of child custody evaluation practices. The analysis was divided into evaluation practices, sole-joint custody decision making, and recommendations. Comparisons between the findings of this study and those of Keilin and Bloom are made. The current practice of child custody evaluations is reported. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

The MMPI-2 considered in the contexts of personality theory, external validity, and clinical utility.

The MMPI-2 promises to be a substantial improvement over its predecessor and is a major contribution to the field of personality assessment. Much of the former research and the clinical experience that one has accumulated over the years will continue to be applicable to the MMPI-2. The author is somewhat surprised that the revision of the basic scales was not a more substantive one. Based on the research literature, psychometric considerations, and clinical needs, a more fundamental revision may have been appropriate. Improvements in and possible limitations in the MMPI-2 are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

MMPI-2 with male and female state and federal prison inmates.

This study examined the base rates, patterns, and configurations of male and female prisoners on the Minnesota Multiphasic Personality Inventory-2 (MMPI-2; J. N. Butcher, W. G. Dahlstrom, J. R. Graham, A. Tellegen, & B. Kaemmer, 1989) validity, basic, supplementary, and content scales and compares them with the MMPI-2 adult norms and with the performance of offenders on the original MMPI (S. R. Hathaway & J. C. McKinley, 1943). Expectations as to which scales would show significant and meaningful elevations and effect scores were generally upheld. The most prominent MMPI-2 scales are Infrequency, 4, 6, 9, MacAndrew Alcoholism Scale-Revised, and Antisocial Practices for both genders, and Scales 5 and Addiction Admission Scale among women. Scales 0 and Responsibility scale appeared to be inhibitory scales. Men and women had similar profile configurations, but the female offenders' scores were more deviant than those of the men.
