The MMPI-2 Clinical Scales and Restructured Clinical (RC) Scales: comparative psychometric properties and relative diagnostic efficiency in young adults

We examined the psychometric properties of the Restructured Clinical (RC) scales (Tellegen et al., 2003) of the MMPI-2 (Butcher, Dahlstrom, Graham, Tellegen, & Kaemmer, 1989) in a large sample (N = 744) of 18-year-old college freshman. We found that the RC scales demonstrated good convergence with their Clinical scale counterparts and were more distinctive than the Clinical scales. The patterns of discriminant correlations for the RC scales were slightly clearer than those of the Clinical scales and a set of other existing MMPI-2 scales. Diagnostic efficiency statistics based on Clinical and RC scale elevation status did not differ appreciably. However, the diagnostic efficiency statistics of cutoff scores derived from mean RC and Clinical scale T scores improved on the traditional scale elevation measures. We consider the clinical implications of these findings.     

An investigation of the psychometric properties of the MMPI-2 Restructured Clinical (RC) scales with mental health inpatients

In this study, we compared the internal psychometric properties and external correlates of the MMPI-2 (Butcher et al., 2001; Tellegen et al., 2003) Restructured Clinical (RC) scales and corresponding MMPI-2 non-K-corrected Clinical scales in a sample of 280 men and 264 women admitted to inpatient psychiatric units. We evaluated the internal psychometric properties of the RC and Clinical scales by intercorrelation analyses and alpha coefficients. We investigated external correlates of scores from the RC and Clinical scales using selected chart variables, selected Symptom Checklist 90-Revised (Derogatis, 1983, 1994) items, and clinician ratings on the Brief Psychiatric Rating Scale (Overall & Gorham, 1988). Results showed psychometric support for the RC scales in terms of improved intercorrelation patterns and comparable or greater alpha coefficients. Further, external correlational analyses revealed varying degrees of evidence of improvement in convergent and discriminant validity.     

Psychometric evaluation of the MMPI-2 Restructured Clinical scales in two Dutch samples

In this article, we evaluate internal validity, internal consistency, and test-retest reliability of the MMPI-2 Restructured Clinical (RC) scales in the Dutch MMPI-2 normative sample (N = 1,244) and a Dutch outpatient psychiatric sample (N = 1,066). We pay special attention to a critique regarding construct drift of RC3 and the redundancy of the RC scales with existing MMPI-2 scales. The results indicate that the RC scales in both samples show comparable or better internal consistencies than the Clinical scales. Also, in both samples, the RC scales demonstrate lower scale-level intercorrelations than the Clinical scales. As to the structural characteristics, principal component analysis of the RC scales provided a clearer pattern than an analysis of the Clinical scales. Furthermore, mean raw scores on the RC scales for men in the Dutch normative sample corresponded highly with those in the U.S. normative sample except for RC2 and RC4. Less correspondence was found for women. Overall, we conclude that the RC scales show satisfactory reliability and promising internal validity in our Dutch samples. We suggest that U.S. validation studies on the RC scales may be generalized to the Dutch-language version of the MMPI-2 RC scales.     

Behavioral correlates of selected MMPI-2 clinical, content, and restructured clinical scales

In this study, we evaluated the validity of the Restructured Clinical (RC; Tellegen et al., 2003) scales by identifying and comparing behavioral correlates of selected RC scales (RCd, RC2, RC4), their original Clinical scale counterparts (Scale 2, Scale 4), and conceptually related Content scales (DEP, ASP, CYN) in an outpatient clinical sample (N = 150). The results of this study indicate that RC4 is a stronger predictor of several antisocial behaviors than Clinical Scale 4 or the Content Scales ASP and CYN. In contrast, RC2 demonstrated significantly lower correlations with several behaviors conceptually related to depression than its Clinical scale counterpart or DEP. DEP was highly correlated with RCd (r = .91, p < .0001), suggesting that the 2 scales may be measuring similar constructs. Overall, the results of this study demonstrate relatively few differences among the scales selected in their ability to predict extratest behaviors.     

Empirical correlates of the MMPI-2 Restructured Clinical (RC) Scales in a nonclinical setting

We examined the empirical correlates of the MMPI-2 Restructured Clinical (RC; Tellegen et al., 2003) scales in a nonclinical setting. We administered 12 criterion measures assessing variables expected to be associated differentially with the RC Scales along with the MMPI-2 to a sample of 1,038 college students (Men, N = 407; Women, N = 631). Criteria included measures of somatization, depression, Machiavellian negativism, drug and alcohol abuse, anger, anxiety, social phobias, obsessive-compulsive tendencies, magical ideation, perceptual aberration, lability, and impulsivity. Results demonstrate good convergent and discriminant validity for the RC scales and add to a growing body of empirical correlates of these scales.     

Psychometric Properties of Various Scales Measuring Psychological Well-Being in a South African Context: The FORT 1 Project

The aim of this study was to do a first phase screening of psychometric properties of various scales measuring facets of psychological well-being so as to address further questions in the FORT 1 project (FORT 1 = Clarifying the nature of psychological strengths). All scales (except one) were developed in a Western context, and measure facets of cognitive, affective, conative, social, and spiritual psychological well-being. As it could not be assumed that scales are valid in South African contexts, a broad screening of their psychometric properties was necessary before specific questions could be adressed. A convenience sample (N=514) including white (n=384) and black (n=130) students and adults from the North West Province and Gauteng areas completed all questionnaires. Psychometric properties of scales varied from acceptable to unacceptable for use in a specific subgroup.     

The phobic stimuli response scales: a new self-report measure of fear

Data from two large undergraduate samples were used to develop the phobic stimuli response scales (PSRS). Factor analyses of data from the first sample (N = 380) led to the creation of several scales, two of which (Social and Blood-Injection Fears) demonstrated good reliability and convergent validity. Analyses of data from a second sample (N = 330) were used to modify the three remaining scales (Animal, Bodily Harm, and Physical Confinement Fears), which also showed sound psychometric properties. As predicted, the PSRS were differentially correlated with neuroticism and extraversion, which may represent predisposing factors for these phobic responses. These new scales improve our understanding of the individual differences that are associated with various fears.     

Psychometric characteristics of Carver and White's BIS/BAS scales in Dutch adolescents and their mothers

The psychometric characteristics of Carver and White's (1994) BIS/BAS scales were examined in 2 groups of Dutch adolescents (497 early adolescents and 237 middle adolescents, M (Age) = 13.0 years and 16.4 years, respectively) and their middle-aged mothers (M (Age) = 45.2 years; N = 734). Confirmatory factor analyses revealed an acceptably fitting 2-factor model for adapted BIS /BAS scales in all 3 groups, reflecting separate BIS and BAS factors. Reliabilities of the 2 scales were satisfactory. The results supported the convergent validity of BIS and BAS scales. BIS was positively correlated with internalizing problem behaviors and neuroticism. BAS was positively correlated with externalizing problem behaviors and extraversion. The discriminant validity of the BIS/BAS scales received mixed support in our data. BIS was negatively correlated with extraversion, and BAS was not correlated with depression. However, BIS was also found to be correlated with externalizing problem behaviors, and BAS was positively correlated with neuroticism. In sum, the scales are suitable for use in research settings, but caution is advocated in application for clinical practice.     

A comparison of the correlational structures and elevation patterns of the MMPI-2 restructured clinical (RC) and clinical scales

The relationship between the MMPI-2 restructured clinical scales and the original clinical scales was evaluated using an outpatient clinical sample (N = 150). Similar patterns of correlations to those reported by Tellegen et al. in 2003, such as high correlations between the restructured scales and their original scale counterparts and lower intercorrelations among the restructured scales than among the original scales, were found in the outpatient sample. The former provided evidence of convergence between the two sets of scales, whereas the latter increases the potential for discriminant validity in the restructured scale profiles. Mean T-scores of the restructured scales were significantly lower than their original scale counterparts for every clinical scale except Scale 1 (hypochondriasis). Individual profiles exhibited fewer scale elevations using the restructured clinical scales (M = 2.15, Mdn = 2.0) than the original clinical scales (M = 3.29, Mdn = 3.0). The majority of client profiles (56%) had fewer scale elevations when plotted using the restructured scales versus the original clinical scales.     

Mapping the MMPI-2 Restructured Clinical scales onto normal personality traits: evidence of construct validity

The MMPI-2 Restructured Clinical (RC; Tellegen et al., 2003) scales were developed to remove common factor variance that saturates the clinical scales and create a more distinct set of measures, yielding a new set of scales with improved convergent and discriminant validity. In this study, we examined the relation between RC scale scores and scores on the Multidimensional Personality Questionnaire (MPQ; Tellegen, in press), a measure of normal personality, using a sample of 811 college students. The results indicate strong convergence between the RC scales and expected MPQ higher order factors and primary scales. The RC scales also demonstrated expected improved convergent and discriminant validity over the clinical scales.     

An Evaluation of the Psychometric Properties and Criterion Validity of the Religious Social Support Scale

This study evaluates the psychometric properties and criterion validity of the Religious Social Support (RSS) Scale in a diverse, representative community sample of new mothers ( N = 1,156). Results indicated that two factors best represented the RSS. Criterion validity was established by demonstrating that the RSS was associated with relational and health outcomes. However, these associations were reduced to statistical insignificance once a general measure of social support was included as a covariate. There were no indications that race moderated either the psychometric properties of the RSS or the relationships between social support and outcomes. Qualitative analyses indicated that religious social support is a salient construct in the lives of women that we studied and suggested ways to improve future developments of RSS scales.     

Psychometric Evaluation of the MMPI–2 Restructured Clinical Scales in Two Dutch Samples

In this article, we evaluate internal validity, internal consistency, and test–retest reliability of the MMPI–2 Restructured Clinical (RC) scales in the Dutch MMPI–2 normative sample (N = 1,244) and a Dutch outpatient psychiatric sample (N = 1,066). We pay special attention to a critique regarding construct drift of RC3 and the redundancy of the RC scales with existing MMPI–2 scales. The results indicate that the RC scales in both samples show comparable or better internal consistencies than the Clinical scales. Also, in both samples, the RC scales demonstrate lower scale-level intercorrelations than the Clinical scales. As to the structural characteristics, principal component analysis of the RC scales provided a clearer pattern than an analysis of the Clinical scales. Furthermore, mean raw scores on the RC scales for men in the Dutch normative sample corresponded highly with those in the U.S. normative sample except for RC2 and RC4. Less correspondence was found for women. Overall, we conclude that the RC scales show satisfactory reliability and promising internal validity in our Dutch samples. We suggest that U.S. validation studies on the RC scales may be generalized to the Dutch-language version of the MMPI–2 RC scales.     

Incremental validity of the MMPI-2 Restructured Clinical (RC) scales in a private practice sample

Building on results reported in Sellbom, Graham, and Schenk (2005), in this study, we examined the incremental validity of the newly introduced MMPI-2 (Butcher et al., 2001) Restructured Clinical (RC) scales (Tellegen et al., 2003) over both the Clinical and Content scales. Participants were 647 clients in private practice who were administered the MMPI-2 and the Multiaxial Diagnostic Inventory (Doverspike, 1990) early in therapy. The results indicate that the RC scales had acceptable internal consistency, reduced intercorrelations (compared to the Clinical scales), and promising convergent and discriminant validity. Hierarchical regression analyses revealed that the RC scales added incrementally to both the Clinical and Content scales in predicting self reported clinical symptoms. These findings suggest that the RC scales are relatively homogenous measures of core clinical constructs that can add unique information to the understanding of private practice clients above and beyond the Clinical and Content scales.     

What do the MMPI-2 restructured clinical scales reliably measure? Answers from multiple research settings

The Restructured Clinical (RC; Tellegen et al., 2003) scales were developed to improve measurement of the core constructs of the MMPI-2 (Butcher et al., 2001) Clinical scales by removing "demoralization," hypothesized to affect these scales adversely. Using 25 samples with MMPI-2 responses from 78,159 subjects across diverse clinical settings, we found that each RC scale was highly correlated with a Supplementary, Content, or Personality Psychopathology 5 (PSY-5; Harkness, McNulty, & Ben-Porath, 1995) scale: higher, in fact, than the correlation between the RC scale and its parent scale. Furthermore, for over half the RC scales (i.e., RC1, RC3, RC7, RC8, and RCd), the correlations were strong enough to conclude that the RC scales replicate MMPI-2 scales with rich empirical foundations; the remaining RC scales were not redundant. Next, we examined reliability estimates using alpha coefficients and interitem correlations and did not reveal superior reliability for most of the RC scales over existing MMPI-2 scales.     

Climate for work group creativity and innovation: Norwegian validation of the team climate inventory (TCI)

The present study assessed the psychometric properties and the validity of the Norwegian translation of the Team Climate Inventory (TCI). The TCI is a measure of climate for innovation within groups at work and is based on the four-factor theory of climate for innovation (West, 1990). Cronbach's alpha revealed satisfactory reliabilities and exploratory factor analysis successfully extracted the four original factors as well as a fifth factor that has also been reported in other studies (N = 195 teams from a wide range of professions). Results from confirmatory factor analysis, using a different sample (N = 106 teams from the Norwegian public postal service), suggested that the five-factor solution had the most parsimonious fit. Criterion validity was explored by correlating TCI scores from 92 post offices and 395 postal distribution teams with customer satisfaction scores. Significant positive relationships were found between three of four TCI scales and customer satisfaction.     

Psychometric properties of the Danish 16PF and EPQ

A Danish translation of the Cattell's 16PF has been used in studies evaluating the effects of prenatal drug exposure. This paper reports a psychometric analysis of the 16PF and Eysenck's EPQ based on a sample of 558 young Danes. Many 16PF scales had unacceptable psychometric properties (as indicated by coefficient alpha and item–total score correlations), but more satisfactory results were obtained with the EPQ N and E scales. A factor analysis of all 16PF and EPQ scales suggested a six factor solution that roughly corresponds to the second-order factor structure obtained by Krug and Johns (1986). It is concluded that the second-order factor structure should be the basis of interpretation of the 16PF in both practical and research contexts.     

Examination of racial differences on the MMPI-2 clinical and restructured clinical scales in an outpatient sample

The current study examined the possibility of differential predictive accuracy of selected Minnesota Multiphasic Personality Inventory-Second Edition (MMPI-2) clinical and Restructured Clinical (RC) scales in a group of Black and White mental health center clients. Results indicate that Black clients scored higher than White clients on one non-K-corrected clinical scale and 4 RC scales. All these differences produced medium effect sizes and were clinically significant according to Greene's (1987) criterion. These differences, however, were not accompanied by differential predictive accuracy of the scales in Black versus White clients. Although additional research is needed, especially on the RC scales, this study indicates that the MMPI-2 is not a biased predictor of symptomatology for Black versus White test takers.
