Validity of the Personality Assessment Inventory Aggression scales and Violence Potential index in veterans with PTSD

In this study, we examined the validity of the Personality Assessment Inventory (PAI; Morey, 1991) Aggression (AGG) scales and Violence Potential index (VPI) in 399 male combat veterans presenting for formal evaluation of posttraumatic stress disorder (PTSD). The AGG scales exhibited convergence with other measures of hostility and violence and demonstrated discriminant validity with alternative constructs. When we examined reports of interpersonal violence in the past year, the AGG composite scale displayed substantial incremental validity over the effects of PTSD severity, demographics, a simple dichotomous question regarding violence in the past 30 days, and MMPI-2 (Butcher, Dahlstrom, Graham, Tellegen, & Kaemmer, 1989) scales measuring aggression. The VPI, however, added no unique explanatory power over the AGG composite scale.     

Validity of the Personality Assessment Inventory Aggression Scales and Violence Potential Index in Veterans With PTSD

Examined humor appreciation of cartoons as a function of sex of subject and type of humor. Four broad types of humor were presented: sexual-exploitative, sexual-nonexploitative, nonsexual-hostile, and nonsexual-nonhostile. Sexual-nonexploitative humor was rated as funnier than the other three types but nonsexual-nonhostile humor was given a more positive overall rating than the other types. Relative to males, females gave greater ratings of hostility to the cartoons and rated them less positively. Correlational analyses further suggested that females were not as affected as males by variations in sexuality, exploitation, and hostility. For males, greater ratings of sexuality were associated with greater funniness ratings while the reverse was true for greater ratings of hostility. Possible interpretations of these data were discussed.     

Homelessness and Response Styles on the Personality Assessment Inventory in a Compensation-Seeking Sample

The relationship between validity measures of the Personality Assessment Inventory (PAI; Morey, 1991) and homelessness was investigated in this archival study. Two groups (N = 50) of compensation-seeking adults were included: homeless and domiciled. The purpose of the study was to determine if differences existed between these 2 groups on the validity measures of the PAI to inform the clinical evaluations of the compensation-seeking homeless. Results of independent sample t tests indicated no significant differences between the homeless and domiciled groups on the 4 validity scales and 2 additional indexes of exaggerated responding (Malingering Index [Morey, 1996] and Rogers Discriminant Function [Rogers, Sewell, Morey, & Ustad, 1996]). Results suggested the compensation-seeking homeless have similar elevations on the PAI validity indexes as domiciled groups seeking compensation.     

Predicting the Completion of an Integrative and Intensive Outpatient Chronic Pain Treatment With the Personality Assessment Inventory

The X-zero distinction has been used as the operational definition of MMPI item subtlety in previous research. A consistent finding has been that the X items, which are obvious in terms of pathological content, can be faked whereas the more subtle zero items cannot be faked. The present study examined the relationship between instructional sets and endorsement patterns, using a more refined, comprehensive measure of item subtlety. Sixty (30 male, 30 female) subjects completed two MMPI protocols, one under a standard instructional set and the other under either a fake-good or fake-bad response set. Order of administration and sex were counterbalanced. In general, the findings for the subtle-obvious dimension paralleled the previous findings with the X-zero distinction. Endorsement of obvious items was a direct function of instructional set, whereas endorsement of subtle items was inversely related to instructional set. Because subtle items did not appear to measure the constructs for which they had been originally intended, other uses for subtle items were discussed.     

The Validity of the Rorschach and the Minnesota Multiphasic Personality Inventory: Results from Meta-Analyses

Results from meta-analyses have been widely cited to defend the validity of the Rorschach. However, the meta-analyses have been flawed. For example, one meta-analysis included results that were obtained by calculating correlations but not results that were obtained by conducting t tests or analyses of variance. When we reanalyzed the data from the most widely cited meta-analysis (Parker, Hanson, & Hunsley, 1988), we found that for confirmatory studies (also called convergent-validity studies), the Minnesota Multiphasic Personality Inventory (MMPI) explained 23% to 30% of the variance, whereas the Rorschach explained only 8% to 13% of the variance. These results indicate that the Rorschach is not as valid as the MMPI.     

The German Adaptation and Standardization of the Personality Assessment Inventory (PAI)

We developed the German Adaptation of the Personality Assessment Inventory (PAI; Morey, 1991) under careful consideration of current adaptation literature and guidelines. The adaptation process included the translation of the 344 items into German, a back translation into English as well as the testing of the language equivalence using a bilingual sample. We then standardized the final German version of the PAI for the German population. We compared the American and German norm and reliability data. The observed differences in PAI scale means did not exceed 5 T scores. Internal consistency reliability showed a similar pattern in both language versions, although the German alpha coefficients were on average slightly lower than the American ones. Factor structure was similar in both versions. We discuss expectations about the German PAI and possible problems for its practical usefulness for the German-speaking population.     

The German Adaptation and Standardization of the Personality Assessment Inventory (PAI)

An attempt was made to evaluate the relationship between left-handedness and oppositional tendencies through the use of the White Space (S) response on the Rorschach. Right and left-handed males were administered the Rorschach, and it was found that the left-handed subjects gave significantly more S responses than did the right-handed males. It was felt that the results of this study indicated the existence of a relationship between hand-preference and oppositional tendency. Caution was raised concerning the assumption that oppositional tendencies foster left-handedness. It was pointed out that opposition could also be produced by being left-handed.     

Relationship Between the Holden Psychological Screening Inventory (HPSI) and the Basic Personality Inventory (BPI) in a Community Sample

Using a sample of 144 mature students, aged 18–53 years, attending a high school upgrading program, the screening properties of the Holden Psychological Screening Inventory (HPSI) and the correspondence of the HPSI to the Basic Personality Inventory (BPI) were evaluated. Correlations between the HPSI and the BPI scales and joint factor analysis of these two inventories demonstrated the validity of HPSI scales and their sampling adequacy from the major components of psychopathology measured by the BPI. Using the BPI as the Gold Standard, the HPSI has almost perfect specificity but the sensitivity of the HPSI is only about 50% at a T-score of 60, whereas at T = 55, the sensitivity is 70%, with a specificity of almost 80%. Overall, results indicated that the three HPSI scales distinctly measure the three major factors of the BPI, and the HPSI has considerable utility as a screening tool.     

Borderline pathology and the Personality Assessment Inventory (PAI): an evaluation of criterion and concurrent validity

In this study, we examined how patients diagnosed with borderline pathology (BP) would respond on the Personality Assessment Inventory (PAI; Morey, 1991) Borderline (BOR) scales in relation to patients without BP pathology. In addition, we examined whether the PAI BOR scales would be related to variables on the Social Cognition and Object Relations Scale (SCORS; Hilsenroth, Stein, & Pinsker, 2004; Westen, 1995) derived from early memory narratives. Results indicate that outpatients with a Diagnostic and Statistical Manual of Mental Disorders (4th ed. [DSM-IV]; American Psychiatric Association, 1994) diagnosis of BP scored significantly higher on the PAI BOR Total (BOR-Total) score, Identity Problems, and Self- Harm scales in comparison to a Non-BP clinical sample. The overall correct classification rate for the presence or absence of BP using the BOR Total scale (T >or= 70) was 73%. In addition, there were several significant relationships between dimensional PAI BOR scales and the presence versus absence of DSM-IV BP. Moreover, both the BOR-Total and Affect Instability scales were significantly related to the SCORS variable Complexity of Representations. We provide clinical examples to illustrate these research findings in an applied manner.     

A Measure of Adolescent Potential for Suicide (MAPS): Development and Preliminary Findings

This paper describes an instrument designed to assess the suicide potential of youth 14–18 years of age who are at risk for suicidal behaviors. A comprehensive measurement theory provides the basis for three central constructs in the Measure of Adolescent Potential for Suicide (MAPS): direct suicide risk factors, related risk factors, and protective factors. The MAPS entails an introductory questionnaire followed by a computer-assisted, structured interview. Two samples were used to examine psychometric properties of the MAPS (n = 43; n = 123). Results revealed generally strong validity (content, criterion, construct) and reliability (internal consistency) for the MAPS. Further verification studies with large and diverse samples are warranted.     

Assessment of Personality Organization in Couple Relationships: Factorial Structure of the Inventory of Personality Organization and Incremental Validity Over Neuroticism

Summary: Creative thinking was explored from several approaches to further understanding of the interrelationship of perception, personality, and cognition. College students (N = 45) were administered the Group Embedded Figures Test (GEFT), the Remote Associates Test (RAT), a questionnaire concerning RAT strategy, and two self-report scales. Field independent subjects were found to be significantly (p < .001) more creative than field dependents. Correlations between the RAT and GEFT and the self-report measures of conformity and creativity, while largely nonsignificant, were in the predicted directions. Results demonstrated that advanced strategy levels and insightful responses were significantly related to high performance on the RAT. Theoretical links between cognitive style and Piagetian concepts were discussed in regard to creative thought. Overall, these findings support the contention that the creative processes should be studied, not as isolated structures, but with relational and multifaceted emphasis.     

Psychometric Evaluation of the Rage Outbursts and Anger Rating Scale in an Outpatient Psychiatric Sample

The primary objective of this study was to examine the psychometric properties of a measure of anger/rage attacks—the Rage Outburst and Anger Rating Scale (ROARS)—in a sample of youth (n = 81, ages 7–17 years, 72.8 % male) receiving treatment at an outpatient pediatric psychiatric clinic. A trained rater completed the ROARS and Clinical Global Impression-Rage (CGI-Rage). Children completed the Spence Children’s Anxiety Scale for Children and Center for Epidemiological Studies Depression Scale. Parents completed the Spence Children’s Anxiety Scale for Parents. Internal consistency (α = .89), inter-rater reliability (κ = .94) and 1-week test–retest reliability (r = .72) were calculated for the ROARS. The ROARS was correlated with CGI-Rage (r = .68, ρ < .001), although not with parent- and child-rated anxiety symptoms or with child-rated depressive symptoms. Implications regarding clinical utility of the ROARS and directions for future research are discussed.     

A General Factor of Personality in the Millon Clinical Multiaxial Inventory-III, the Dimensional Assessment of Personality Pathology, and the Personality Assessment Inventory

A General Factor of Personality (GFP) occupies the apex of the hierarchy in three prominent personality disorder inventories. On the Millon Clinical Multiaxial Inventory-III, a GFP accounted for 41% of the variance in two second-order factors, 31% of the variance in five first-order factors, and 26% of the variance in all 24 scales. On the Dimensional Assessment of Personality Pathology, a GFP accounted for 61% of the variance in six first-order factors and 36% of the variance in all 18 scales. In a cross-validation study of the Personality Assessment Inventory, a GFP accounted for 65% of the variance in two second-order factors, 47% of the variance in five first-order factors, and 27% of the variance in all 18 scales.     

A Psychometric Examination of the Pathological Obsessive Compulsive Personality Scale (POPS): Initial Study in an Undergraduate Sample

Obsessive-compulsive personality disorder (OCPD) has been subject to numerous definition and classification changes, which has contributed to difficulties in reliable measurement of the disorder. Consequently, OCPD measures have yielded poor validity and inconsistent prevalence estimates. Reliable and valid measures of OCPD are needed. The aim of the current study was to examine the factor structure and psychometric properties of the Pathological Obsessive Compulsive Personality Scale (POPS). Participants (N = 571 undergraduates) completed a series of self-report measures online, including the POPS. Confirmatory factor analysis was used to compare the fit of unidimensional, five factor, and bifactor models of the POPS. Convergent and divergent validity were assessed in relation to other personality dimensions. A bifactor model provided the best fit to the data, indicating that the total POPS scale and four subscales can be scored to obtain reliable indicators of OCPD. The POPS was most strongly associated with a disorder-specific measure of OCPD, however there were also positive associations with theoretically disparate constructs, thus further research is needed to clarify validity of the scale.     

The Inwald Personality Inventory (IPI) and Hilson Research inventories: Development and rationale

This article provides a “behind-the-scenes” account of how and why the Inwald/ Hilson tests were developed. Since the 1970s, personality testing has been adapted and customized for use in selecting applicants for different occupations, including police, public safety, fire and emergency services personnel. The author developed the Inwald Personality Inventory (IPI) in 1979 as the first comprehensive behaviorally-based personality measure designed and validated specifically for use in high risk occupations, such as law enforcement. Over time, studies consistently demonstrated that the IPI was a better predictor of poor job performance than were traditional tests of psychopathology. While antisocial behavior patterns and characteristics measured by the IPI predicted poor job performance, there also developed a need for measures that would predict above-average/excellent performance in the workplace. In 1988, the author designed and validated the first comprehensive test of “positive” work-related characteristics or “emotional IQ,” the Hilson Personnel Profile/Success Quotient (HPP/SQ). Other instruments followed, including the Inwald Survey 5 — Revised (IS5-R) with questions added on domestic violence. This article describes the theoretical rationale, development and validation of several instruments developed by the author and now widely used for high risk occupations and for screening corporate managers and key personnel in occupational settings.     

Concurrent validity of the Personality Assessment Inventory Alcohol Problems (ALC) Scale in a college student sample

The concurrent validity of the Alcohol Problems scale (ALC) was investigated in a college student sample (N = 200). The relationships between the ALC and associated features of alcohol problems (e.g., consumption patterns, expectancies, maladaptive coping, and stress) were examined. The validity of the ALC for identifying clinically significant alcohol problems (assessed with the Structured Clinical Interview for the fourth edition ofthe Diagnostic and Statistical Manual of Mental Disorders) was also examined. The ALC was related to the associated features and was a valid indicator of alcohol problems. T scores of 80, 85, and 90 had superior hit rates for alcohol abuse; and scores of 80, 85, and 90 had superior hit rates for alcohol dependence.
