Does the Convergent Validity of the PAI Antisocial Features Scale Depend on Offender Response Style?

Researchers have recently questioned the utility of the response style indicators included on many self-report measures of personality and psychopathology. We examined whether the size of convergent validity coefficients for Personality Assessment Inventory (PAI) Antisocial Features (ANT) scores depends on PAI validity scale scores. Using PAI and Psychopathy Checklist–Revised (PCL–R) scores from 477 offenders evaluated for civil commitment as sexually violent predators, we found that PAI Positive Impression (PIM), Negative Impression (NIM), Malingering Index (MAL), Defensiveness Index (DEF), and Infrequency (INF) scores moderated the association between ANT and PCL–R scores. The association between ANT and PCL–R scores decreased as offenders overstated psychopathology (i.e., higher NIM or MAL scores) or exhibited increasing disengagement (i.e., higher INF scores). However, the association between ANT and PCL–R scores increased as offenders engaged in defensive reporting (i.e., higher PIM or DEF scores). The interaction effects were most common for ANT–E (Egocentricity), and to a lesser extent ANT–A (Antisocial Behaviors). PAI discriminant function validity indexes did not exhibit moderating effects on ANT and PCL–R scores. There was no evidence of validity scale suppression effects. These findings provide support for the potential role of some PAI response style measures for ANT scale interpretation in forensic settings.     

Personality diagnostic questionnaire-revised (PDQ-R) personality disorder scores and negative life events independently predict changes in hopkins symptom checklist (SCL-90) Psychopathology Scores

The present study employed a prospective design to investigate whether Personality Diagnostic Questionnaire—Revised (PDQ-R) scores and/or Hassles Scale—Revised (HS-R) scores predict changes in Axis I psychopathology levels over 1 month, in a nonclinical sample of young adults. The PDQ-R, HS-R, and Hopkins Symptom Checklist (SCL-90) were administered to a mixed-sex sample of 100 undergraduate students on two occasions separated by 1 month. Hierarchical multiple regression analyses indicated that (1) time 1 PDQ-R composite scores predicted changes in scores on 11 SLC-90 scales; (2) time 1 PDQ-R impairment/distress index scores predicted changes in SCL-90 general symptom index scores; (3) only one of the individual PDQ-R personality disorder subscales—the schizotypal personality disorder subscale—predicted changes in SCL-90 general symptom index scores; (4) HS-R scores predicted changes in scores on 9 SCL-90 scales; and (5) in only 3 of the 27 analyses conducted did the statistical interaction between PDQ-R and HS-R scores predict changes in SCL-90 scores. These findings indicate that personality disorder symptomatology and negative life events may independently predict changes in Axis I psychopathology levels and, thus, support the continued inclusion of Axis II and Axis IV in future versions of the Diagnostic and Statistical Manual of Mental Disorders.     

Assessment of shame and guilt in a psychiatric sample: a comparison of two measures

The relationship between measures of shame, guilt, and psychopathology was examined in a heterogeneous inpatient sample (n=82) using the Test of Self-Conscious Affect (TOSCA) and the Personal Feelings Questionnaire-2 (PFQ-2). It was predicted that both shame scales would correlate positively with measures of psychopathology. This hypothesis was supported in bivariate analyses, however, when partialed for each respective guilt scale, only the TOSCA maintained significant associations with measures of psychopathology. It was predicted that only the PFQ-2 guilt scale would correlate positively with measures of psychopathology, and this hypothesis was supported in both bivariate analyses and partial correlations, controlling for shame scores. These findings support previous work, suggesting that the TOSCA and PFQ-2 guilt scales assess different constructs of guilt. Methodological issues of shame and guilt assessment with psychiatric patients also are discussed.     

Detection of malingering of psychiatric disorder with the personality assessment inventory: an investigation of criminal defendants

To assess the diagnostic accuracy of the Personality Assessment Inventory (PAI; Morey, 1991) Validity scales for the detection of malingered psychiatric disorders, we divided a sample of criminal defendants referred for forensic evaluation by the federal courts into malingering and not malingering groups based on their performance on the Structured Interview of Reported Symptoms (Rogers, Gillis, & Bagby, 1990). Logistic regression analyses (LGAs) revealed that there were no differences between the malingering and not malingering groups with respect to age, race, years of education, history of drug abuse, or number of previous felony convictions. LGA with malingering versus not malingering as the criterion revealed that the PAI Negative Impression Management (NIM) scale but not the Rogers Discriminant Function (RDF; Rogers, Sewell, Morey & Ustad, 1996) nor the Malingering index (MAL; Morey, 1996) significantly differentiated the malingering from the not malingering group. Receiver operating characteristics analyses demonstrated acceptable sensitivity and specificity for the NIM scale but not the RDF scale or the MAL index. We discuss the results in terms of the suggested cutoff scores for the PAI Validity scales in detecting criminal defendants who are attempting to feign psychiatric disorder.     

MMPI-2 characteristics of transsexuals requesting sex reassignment: comparison of patients in prehormonal and presurgical phases

To assess psychopathology in transsexuals at different phases of sex reassignment, we administered the Spanish adaptation of the MMPI-2 (Avila-Espada & Jiménez-Gómez, 1999) to 107 male-to-female and 56 female-to-male transsexuals. Except for the Mf scale, mean T scores from the Clinical scales were within the normal range and did not differ between sexes. Male-to-female transsexuals seeking sex-reassignment hormonal therapy, but not female-to-male patients, scored significantly higher on the Depression, Hysteria, Psychopathic Deviate, Schizophrenia, and Social Introversion scales than patients seeking sex-reassignment surgery. The results show that the majority of patients were free of psychopathology. Transsexuals in the initial phases of sex reassignment may experience more distress than in later phases; however, these results are unlikely to reflect clinically relevant differences.     

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.     

Psychometric characteristics of the MMPI-2 Cook-Medley Hostility scale

The Minnesota Multiphasic Personality Inventory (MMPI; Hathaway & McKinley, 1943) Cook-Medley Hostility scale (Ho) has been studied a great deal because of its relation to coronary disease and mortality. However, little research has been conducted with the Ho scale on the revised MMPI (MMPI-2; Butcher, Dahlstrom, Graham, Tellegen, & Kaemmer, 1989). This study examined the psychometric characteristics of the MMPI-2 Ho scale. Only nine of the original 50 Ho items were slightly changed in the revision. Ho scores were highly correlated with MMPI-2 scales CYN, K, TPA, and ASP, supporting the interpretation of Ho as a measure of cynicism. High correlations with other MMPI-2 scales also suggested that Ho is related to general psychopathology and negative affectivity. Male Ho scorers were rated by their spouses as hotheaded, bossy, demanding, and argumentative. For women, Ho scale scores were less strongly associated with ratings of overt hostility. Principal components analysis of Ho revealed four underlying dimensions: Cynicism, Hypersensitivity, Aggressive Responding, and Social Avoidance.     

Estimation of MCMI DSM-III Axis II Constructs From MMPI Scales and Subscales

Wiggins, Harris and Lingoes, and Serkownek Minnesota Multiphasic Personality Inventory (MMPI) scores were used to predict Millon Clinical Multiaxial Inventory (MGMI) scores in a 100-patient sample. Equations from the first sample were cross-validated on a sample of 212 inmate subjects. We conclude that scores on 19 of the 20 MCMI scales can be successfully predicted by the Wiggins, Harris and Lingoes, and Serkownek subscales of the MMPI. In further cross-validation, the equations were used to predict the Morey, Waugh, and Blashfield MMPI composites for the prison sample, again with strongly positive results. The results appear quite promising for the estimation of personality disorder constructs from MMPI scales and subscales.

Affective Styles in Panic Disorder and Specific Phobia: Changes Through Cognitive Behavior Therapy and Prediction of Remission

Affective styles appear to be relevant to the development of psychopathology, especially anxiety disorders. The aim of the current study was to investigate changes in affective styles in patients with panic disorder and specific phobia, as a result of undergoing cognitive-behavioral therapy, and to identify a possible link between certain affective styles and remission. The sample consisted of outpatients (N = 101) suffering from panic disorder, specific phobia, or agoraphobia who completed the Affective Style Questionnaire (ASQ) before and after therapy, as well as at a 6-month follow-up assessment. Multivariate analyses of variance were conducted to test for changes due to therapy. Logistic regression analyses were calculated to test for the impact of affective styles on remission from anxiety disorders, and hierarchical regression analyses were calculated to examine the association between changes in affective styles and symptom reduction. Results indicated significant increases on the ASQ subscales adjusting and tolerating after therapy. Concealing did not decrease significantly after therapy. In addition, higher scores on adjusting significantly predicted remission from anxiety disorders. Finally, we found a significant association between increases on the adjusting scale and the reduction of anxiety symptoms.     

Life event categories differentially predict psychopathology symptom levels.

The present study used a prospective design to investigate whether eight categories of daily negative life events or "hassles" differentially predict psychopathology levels, and/or changes in psychopathology levels over 1 month in a mixed-sex, nonclinical sample of undergraduate subjects. Hassles were assessed using the Revised Hassles Scale (HS-R; DeLongis, 1985); psychopathology was assessed using the Hopkins Symptom Checklist (SCL-90; Derogatis, Lipman, & Covi, 1973) on two occasions, separated by 1 month. Scores on all eight HS-R subscales predicted Time 2 scores on most or all of the SCL-90 psychopathology scales. However, the magnitudes of these correlations varied widely, indicating that these subscales may be substantially different in their abilities to predict psychopathology levels.     

Reliability of self-reported attachment style in patients with severe psychopathology

Little is known about whether severe psychopathology influences the assessment of self-reported attachment style. Fifty-eight randomly selected adult psychiatric inpatients completed the Experiences in Close Relationship questionnaire (ECR; Brennan, Clark, & Shaver, 1998) and were administered the 24-item Brief Psychiatric Rating Scale (BPRS; Ventura et al., 1993) and the Hamilton Depression Rating Scale (HDRS; Hamilton, 1960) at both admission and discharge. The Structured Clinical Interview for DSM-IV (SCID-I; First, Spitzer, Gibbon, & Williams, 1996) was used to establish Axis I diagnoses. The ECR scales showed good internal consistency and absolute stability both in patients with (n = 24) and without (n = 34) a psychotic disorder. Relative stability was only fair among patients with psychotic disorders but good among patients without psychotic disorders. Neither higher BPRS or HDRS scores, nor the presence of a psychotic disorder, significantly reduced the retest reliability of the ECR scales. These findings suggest that self-report measures might provide a reliable assessment of attachment style in patients with severe psychopathology, except for the most severely impaired patients.     

Convergent Validity of the Early Memory Index in Two Primary Care Samples

Karliner, Westrich, Shedler, and Mayman (1996) developed the Early Memory Index (EMI) to assess mental health, narrative coherence, and traumatic experiences in reports of early memories. We assessed the convergent validity of EMI scales with data from 103 women from an urban primary care clinic (Study 1) and data from 48 women and 24 men from a suburban primary care clinic (Study 2). Patients provided early memory narratives and completed self-report measures of psychopathology, trauma, and health care utilization. In both studies, lower scores on the Mental Health scale and higher scores on the Traumatic Experiences scale were related to higher scores on measures of psychopathology and childhood trauma. Less consistent associations were found between the Mental Health and Traumatic Experiences scores and measures of health care utilization. The Narrative Coherence scale showed inconsistent relationships across measures in both samples. In analyses assessing the overall fit between hypothesized and actual correlations between EMI scores and measures of psychopathology, severity of trauma symptoms, and health care utilization, the Mental Health scale of the EMI demonstrated stronger convergent validity than the EMI Traumatic Experiences scale. The results provide support for the convergent validity of the Mental Health scale of the EMI.     

Reliability, diagnostic efficiency, and validity of the Millon adolescent clinical inventory: examination of selected scales in psychiatrically hospitalized adolescents

This study examined the internal consistency, diagnostic efficiency, and validity of selected scales of the Millon adolescent clinical inventory (MACI; Millon et al., Manual for the Millon Adolescent Clinical Inventory, National Computer Systems, Minneapolis, MN, 1993). 241 psychiatrically hospitalized adolescents were administered the MACI and a battery of established self-report measures and a multidisciplinary team independently assigned DSM-IV psychiatric diagnoses at the time of discharge. The internal consistency of MACI scales ranged from 0.71 to 0.93. Conditional probabilities (sensitivity, specificity, positive predictive power, and negative predictive power) were calculated for selected disorders using independently generated clinical diagnoses as the standard. The diagnostic efficiencies for the selected scales were variable, with adequate performance for predicting classes of diagnoses but not for specific diagnoses. The MACI showed good criterion validity for most disorders, with participants with a clinical diagnosis having a significantly higher corresponding MACI scale score than participants not assigned that diagnosis. Concurrent validity, tested by correlating MACI scale scores with those of relevant, validated measures, was generally good. The MACI appears to be a psychometrically sound self-report instrument and appears valuable as a screening instrument for many problems found in adolescent psychiatric inpatients.     

Overload (Book)

Relationships between various personality styles measured by the basic and pathological personality scales of the Millon Clinical Multiaxial Inventory (MCMI) and mood or symptom states measured by the Profile of Mood State scales were examined. The MCMI personality scale-POMS symptom/mood scale relationships found in this study are compared with MCMI personality scale-MMPI and SCL-90 symptom/mood scale relationships reported in the MCMI manual. Consistent associations of moderate strength were found between: (a) the MCMI Compulsive-Conforming and Passive-Aggressive (Negativistic) scales (negative and positive associations, respectively) and various measures of depression, anxiety and hostility: (b) the MCMI Avoidant, Schizotypal and Borderline-Cycloid scales and various measures of depression and anxiety; (c) the MCMI Schizoid-Asocial scale and various measures of depression; and (d) the Histrionic-Gregarious scale and various measures of high energy-activity. These MCMI personality scale-symptom/mood scale relationships are generally consistent both with the underlying theory of personality and psychopathology upon which the MCMI is based and with the personality-symptom scale relationships found within the MCMI.     

An examination of the relationship between personality patterns and symptom/mood patterns

Relationships between various personality styles measured by the basic and pathological personality scales of the Millon Clinical Multiaxial Inventory (MCMI) and mood or symptom states measured by the Profile of Mood State scales were examined. The MCMI personality scale-POMS symptom/mood scale relationships found in this study are compared with MCMI personality scale-MMPI and SCL-90 symptom/mood scale relationships reported in the MCMI manual. Consistent associations of moderate strength were found between: (a) the MCMI Compulsive-Conforming and Passive-Aggressive (Negativistic) scales (negative and positive associations, respectively) and various measures of depression, anxiety and hostility; (b) the MCMI Avoidant, Schizotypal and Borderline-Cycloid scales and various measures of depression and anxiety; (c) the MCMI Schizoid-Asocial scale and various measures of depression; and (d) the Histrionic-Gregarious scale and various measures of high energy-activity. These MCMI personality scale-symptom/mood scale relationships are generally consistent both with the underlying theory of personality and psychopathology upon which the MCMI is based and with the personality-symptom scale relationships found within the MCMI.     

Psychometric properties of the Minnesota Multiphasic Personality Inventory-Adolescent (MMPI-A) Clinical, Content, and Supplementary scales in a forensic sample

In this study, we evaluated the internal psychometric properties and external correlates of scores on the Clinical, Content, and Supplementary scales in a forensic sample of 496 adolescents (315 boys and 181 girls) who were court-ordered to receive psychological evaluations. We examined Cronbach's alpha coefficients, scale intercorrelation matrices, and frequencies of scale elevations. Further, we found varying degrees of support for the convergent and discriminant validity of scores on the MMPI-A (Butcher et al., 1992 ) Clinical, Content, and Supplementary scales. This study adds to the body of literature establishing the utility of the MMPI-A in forensic evaluations.     

Detection of overreported psychopathology with the MMPI-2-RF [corrected] validity scales

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).     

Assessing MMPI Constructs Through the Measurement of Response Latencies

Responses to the Minnesota Multiphasic Personality Inventory (MMPI) were assessed with respect to their relevance to schema theory. The relation between scores on self-reported personality dimensions and the speed of processing test items associated with each dimension was examined. With previously derived factor analytic content scales, negative correlations were obtained between scale scores and mean latencies for endorsing relevant items, and positive correlations were found between scale scores and mean latencies for rejecting relevant items. A similar analysis completed on the traditional clinical scales revealed no such pattern. Results were interpreted as supporting the conceptualization of item responding as a content-based, schema-relevant process.     

Construct validity of the misrepresentation scales of the psychological screening inventory

This study provides construct validity evidence and reliabilities (consistency and stability) for 5 misrepresentation (response distortion) scales of the Psychological Screening Inventory (PSI; Lanyon, 1970, 1973, 1978) in assessing 3 constructs: exaggeration of psychopathology, exaggeration of personal virtue, and exaggeration of health problems. Using data from forensic cases, the existence and independence of these 3 constructs were confirmed in data from the MMPI-2 (Butcher, Dahlstrom, Graham, Tellegen, & Kaemmer, 1989) and the Balanced Inventory of Desirable Responding (Paulhus, 1986, 1991). The PSI scales were then shown to load highly on these constructs. The PSI scales also showed the expected patterns when their mean scores were examined for 15 sets of responses from participant groups with varied motivations to misrepresent. We present receiver operating characteristic data to show the success of the scales in distinguishing between simulators and appropriate comparison groups. Using the same data, we also present classification accuracy in terms of positive predictive power and negative predictive power based on a sensitivity level of 90% and misrepresentation base rates of .20 and .10.
