Convergence of the dimensional assessment of personality pathology (DAPP-BQ) and the five-factor personality inventory for the international classification of diseases 11th edition (FFiCD) in the context of the five-factor model and personality disorders.

The current manuscript presents the convergence of the Dimensional Assessment of Personality Pathology (DAPP-BQ), using its short form the DAPP-90, and the Five-Factor Personality Inventory for International Classification of Diseases (ICD-11), the FFiCD, in the context of the five-factor personality model and the categorical approach of personality disorders (PDs). The current manuscript compares the predictive validity of both the FFiCD and the DAPP-90 regarding personality disorder scales and clusters. Results demonstrate a very high and meaningful convergence between the DAPP-90 and the FFiCD personality pathology models and a strong alignment with the FFM. The DAPP-90 and the FFiCD also present an almost identical predictive power of PDs. The DAPP-90 accounts for between 18% and 47%, and the FFiCD between 21% and 47% of PDs adjusted variance. It is concluded that both DAPP-90 and FFiCD questionnaires measure strongly similar pathological personality traits that could be described within the frame of the FFM. Additionally, both questionnaires predict a very similar percentage of the variance of personality disorders.

Examination of Construct Validity of ANX and DEP Scales of the PAI-A.

Anxiety and depression are the two most common psychiatric problems of adolescence. The Personality Assessment Inventory, Adolescent Version (PAI-A) is a broadband instrument designed to assist in the detection and differential diagnosis of common psychiatric disorders in adolescents, and it includes a Depression scale (DEP) to detect the presence of major depressive episodes and an Anxiety scale (ANX) designed to detect clinically significant anxiety. However, there is limited research on this measure. The current study examined both the convergent and discriminant validities of the PAI-A Anxiety and Depression scales by observing their relationships to other self-report measures (e.g., PAI-A scales, MMPI-A), observer ratings (e.g., HPRS), and performance-based measures (e.g., Rorschach CS). The sample consisted of 352 records of the psychological assessments of adolescent inpatients between the ages of 13 to 17; the sample was about equally male (51.6%) and female with a mean age of 15.5 years. The sample was ethnically diverse with 48.7% of individuals identifying as Caucasian, 12.9% Black, 16% Hispanic, 2.6% Asian, 3.2% Other, and 16.6% unknown. There is strong evidence for convergent validity for the PAI-A ANX and DEP scales with r's ranging from .11 to .78. There is moderate evidence for discriminant validity for these scales. Results demonstrated that PAI-A scales correlated strongest with self-report, followed by therapist rating scale, and then performance-based measures. Various strengths of the PAI-A for the assessment of anxiety and depression are discussed.

Is an irritable ADHD profile traceable using personality dimensions? Replicability, stability, and predictive value over time of data-driven profiles.

Pediatric attention deficit/hyperactivity disorder (ADHD) is a heterogeneous condition. In particular, children with ADHD display varying profiles of dispositional traits, as assessed through temperament and personality questionnaires. Previous data-driven community detection analyses based on temperament dimensions identified an irritable profile of patients with ADHD, uniquely characterized by elevated emotional dysregulation symptoms. Belonging to this profile increased the risk of developing comorbid disorders. Here, we investigated whether we could replicate this profile in a sample of 178 children with ADHD, using community detection based on personality dimensions. Stability of the identified profiles, of individual classifications, and clinical prediction were longitudinally assessed over a 1-year interval. Three personality profiles were detected: The first two profiles had high levels of neuroticism, with the first displaying higher ADHD severity and lower openness to experience (profile 1; N = 38), and the second lower agreeableness (profile 2; N = 73). The third profile displayed scores closer to the normative range on all five factors (profile 3; N = 67). The identified profiles did only partially replicate the temperament-based profiles previously reported, as higher levels of neuroticism were found in two of the three detected profiles. Nonetheless, despite changes in individual classifications, the profiles themselves were highly stable over time and of clinical predictive value. Whereas children belonging to profiles 1 and 2 benefited from starting medication, children in profile 3 did not. Hence, belonging to an emotionally dysregulated profile at baseline predicted the effect of medication at follow-up over and above initial ADHD symptom severity. This finding suggests that personality profiles could play a role in predicting treatment response in ADHD.

Comparative Content Analysis of Self-Report Scales for Level of Personality Functioning.

Content validity analyses of eight self-report instruments for assessing severity of personality disorder (PD), also known as Level of Personality Functioning (LPF), were conducted using the conceptual scheme of the Alternative Model for Personality Disorders (AMPD; APA, 2013). The item contents of these eight inventories were characterized for the LPF constructs of Identity (ID), Self-Direction (SD), Empathy (EM), and Intimacy (IN) along with the pathological personality trait domains of Negative Affectivity, Detachment, Antagonism, Disinhibition, and Psychoticism. Severity of pathology (SV) reflected in item content was also rated. Raters demonstrated robust agreement for AMPD and SV constructs across instruments. Similarity between instrument AMPD construct profiles was quantified by intraclass correlations (ICC). Results showed the instruments were generally similar in AMPD-construct coverage, but some important differences emerged. The subscales of the instruments also were characterized for the degree to which they reflect the four LPF (ID, SD, EM, IN) domain constructs. Collectively, these content validity comparisons clarify the equivalence of instruments for AMPD constructs and the relative proportions of construct coverage within instrument subscales. These results can inform future research with LPF self-report instruments and guide clinicians in selecting an LPF-related instrument for use in practice.

Expanding G-Theory Models to Incorporate Congeneric Relationships: Illustrations Using the Big Five Inventory.

We used structural equation modeling techniques to expand traditional generalizability theory (G-theory) models to allow for congeneric relationships among item responses while accounting for the primary sources of measurement error that affect results from objectively scored, self-report measures. Data came from 919 respondents who completed the Agreeableness, Conscientiousness, Extraversion, Neuroticism, and Openness subscales of the Big Five Inventory (BFI; John et al., 1991) on two occasions. When compared to traditional and factor-based essential tau-equivalent G-theory models, congeneric models on average yielded superior fit statistics, higher estimates of reliability, and lower estimates of transient and specific-factor measurement error. Essential tau-equivalent and congeneric factor models also were configured to allow for simultaneous partitioning of systematic and measurement error variance at both total score and individual item levels. We provide detailed guidelines, examples, and computer code in R for all models discussed in an extended online supplement to enable readers to apply the demonstrated techniques.

A Bifactor Model of Personality Organization.

The aim of this study was to explore the viability of a bifactor model for the Inventory of Personality Organization (IPO), which is a self-report measure of personality functioning based on Kernberg's model of personality organization. A heterogeneous, predominantly clinical sample (N = 616) completed the German 83-item version of the IPO. Confirmatory and Exploratory Factor Analyses were applied to explore the factor structure of the IPO. We were able to establish a bifactor model with a general factor of personality functioning and three specific factors (Aggression, Reality Testing, Moral Values), which represent additional dimensions of personality organization. Virtually all items showed substantial positive loadings on the general factor, explaining roughly 66% of the common variance. Furthermore, we found support for convergent and discriminant validity of general and specific factors with regard to interview-based assessments of personality disorders and personality organization. The results lend support to a bifactor approach to Kernberg's model of personality organization. We also present a 30-item brief form of the IPO that efficiently implements the bifactor approach and may be further validated in future studies.

Exploring Gender Differences in Machiavellianism Using a Measurement Invariance Approach.

Research suggests that men and women differ on mean levels of Dark Triad personality constructs such as Machiavellianism, but few studies have investigated whether or not these differences are due to actual latent trait differences or bias in measurement. Further, recent research suggests important challenges associated with existing measures of MACH in terms of overlap with psychopathy and matching expert descriptions. The present study took a recently developed measure of Machiavellianism (the Five Factor Machiavellianism Inventory; FFMI), based on the five-factor model, and examined its invariance across gender. Strong (or scalar) factorial invariance was established, indicating that latent factor means can be compared between men and women using this measure. Mean-level differences showed that men had higher levels of latent factors related to antagonism and social dominance. In terms of total score, men reported significantly higher mean levels of Machiavellianism. The findings of the present study lend support to the notion that mean level differences in Machiavellianism across gender are not artifacts of measurement bias.

Further Validation of the Elemental Psychopathy Assessment - Short Form (EPA-SF) in a Large University Sample.

The purpose of the current study was to provide further validation of the short form of the Elemental Psychopathy Assessment (EPA-SF), which was developed on the basis of a general personality model, the Five Factor Model (FFM) of personality. This study evaluated the internal structure of the EPA-SF trait scales, and examined the EPA-SF scales against two other psychopathy measures, the Triarchic Psychopathy Measure (TriPM) and the Expanded Leveson Self-Report Psychopathy Scales (E-LSRP), as well as a general FFM measure, in a sample of 924 university students. Exploratory Structural Equation Modeling generally supported internal structure for EPA-SF scales, in that the 18 EPA-SF traits generally loaded onto their four respective domain scales: Antagonism, Emotional Stability, Inhibition and Narcissism. Tucker's congruence coefficients (.95-.99) indicated excellent replicability of the original structure. The EPA-SF total and domain scale scores also showed moderate to large correlations with TriPM, E-LSRP and FFM domain scales in a manner mostly consistent with conceptual expectations. Finally, EPA-SF trait scales were also mostly associated with their corresponding FFM trait scale counterparts. Overall, the EPA-SF scale scores showed evidence for good convergent and discriminant validity.

Factorial Structure and Nomological Network of the Inventory of Callous-Unemotional Traits Accounting for Item Keying Variance.

The factorial structure of the Inventory of Callous Unemotional Traits (ICU) is currently under dispute. The present study aims to test the factorial structure of a Greek adaptation of the ICU by considering item keying variance and examining alternative theoretical and empirically derived models. Additionally, it aims to investigate the nomological network of the ICU subscales, after controlling for item keying variance. The sample consisted of 1536 Greek-Cypriot adolescents, who completed a battery of questionnaires, including the ICU. Results showed that the consideration of item keying variance improved the overall fit of all the examined models and led to significant changes in the predictive validity of the subscales, while method factors presented distinct patterns of associations with external variables. Overall, results suggest that ICU is contaminated by item keying variance, which can be filtered out to provide clinically useful insight into the factorial structure of the ICU.

Psychometric Properties of the Personality Inventory for DSM-5-Brief Form in a Community Sample with High Rates of Trauma Exposure.

In the current study, we used a sample of predominantly African-American women with high rates of trauma exposure (N = 434) to examine psychometric properties of the Personality Inventory for DSM-5-Brief Form (PID-5-BF). We compared model fit between a model with five correlated latent factors and a higher-order model in which the five latent factors were used to estimate a single "general pathology" factor. Additionally, we computed estimates of internal consistency and domain interrelations and examined indices of convergent/discriminant validity of the PID-5-BF domains by examining their relations to relevant criterion variables. The expected five-factor structure demonstrated good fit indices in a confirmatory factor analysis, and the more parsimonious, higher-order model was retained. Within this higher-order model, the first-order factors accounted for more variance in the criterion variables than the general pathology factor in most instances. The PID-5-BF domains were highly interrelated (rs = .38 to .66), and convergent/discriminant validity of the domains varied: Negative Affectivity and Detachment generally showed the hypothesized pattern of relations with external criteria, while Antagonism and Disinhibition displayed less consistent and discriminant relations. Results are discussed in terms of the costs and benefits of using brief pathological trait measures in samples characterized by high levels of psychopathology.

The Effect of Personality Traits on Cognitive Behavioral Therapy Outcomes in Student Pharmacists with Rat Phobia: A Randomized Clinical Trial.

Background: Little is known about which personality traits determine the effectiveness of various types of cognitive-behavioral therapy (CBT) on animal phobia. The objective of the present study was to investigate a possible association between personality traits and the outcome of single- and multi-session CBT. Methods: The present randomized clinical trial was conducted from November 2018 to May 2019 in Shiraz, Iran. Forty female students with rat phobia, who met the Diagnostic and Statistical Manual of Mental Disorders (DSM-V) criteria, were systematically allocated into a single- and a multi-session therapy group (odd numbers one-session treatment, even numbers multi-session treatment). In both groups, the students were gradually exposed to rats as part of the treatment. Psychological measures (state-anxiety, rat phobia, and disgust questionnaires) were used to compare pre- and post-intervention outcomes. Multivariate analysis of covariance was used to assess which personality traits influenced the intervention outcome. The statistical analysis was performed using SPSS (version 20.0) and P values<0.05 were considered statistically significant. Results: Rat phobia was positively and significantly affected by conscientiousness (P=0.001) and agreeableness (P=0.003). Of these personality traits, only a higher degree of conscientiousness resulted in a further reduction of state anxiety after the intervention (P=0.005). There were no significant differences between the pre- and post-intervention outcomes. Conclusion: The outcome of single- and multi-session rat phobia therapies was associated with specific personality traits of the participants, namely conscientiousness and agreeableness. Both intervention methods had an equal effect on reducing rat phobia.

Measuring Uncertainty Intolerance in Surgical Residents Using Standardized Assessments.

BACKGROUND: Physicians are frequently called on to make medical decisions despite being uncertain about the outcomes of these choices. The psychological stress associated with these dilemmas, known as "Uncertainty Intolerance" (UI), can significantly impact the quality of a physician's practice as well as their own mental health. Coping with uncertainty is an important competency that all residents must master, and some residency programs are introducing new education initiatives aimed at improving UI. However, currently there is no standard protocol for measuring UI or the effectiveness of such interventions and there are no established methods for identifying the residents who would most benefit from the training. In this study, we aim to use the Physician Reaction to Uncertainty (PRU) and Physician Risk Attitude (PRA) scales as assessments for UI in surgical residents, and to determine if Myers-Briggs Type Indicator (MBTI) personality factors are associated with PRU and PRA scores and can be used to identify residents who are more likely to have higher UI. MATERIALS AND METHODS: The PRU and PRA scales, and the MBTI assessment were administered to a total pool of 71 general surgery residents. In addition to the survey questions, residents provided information regarding their gender (male or female), and stage of training (junior or senior). RESULTS: In total, 45 male residents and 25 female residents completed the PRA and PRU scales (98.6%). There were no statistically significant differences when comparisons were made between junior and senior residents or male and female residents. Thirty seven male residents and 18 female residents also completed the MBTI assessment (80.4% and 72%, respectively). PRU and PRA scores were analyzed with respect to personality factors to determine if certain dichotomies are associated with increased UI. There was a trend toward higher UI in individuals identifying with Judging. CONCLUSIONS: In this study, we have conducted a pilot study using the PRU and PRA scales to measuring the success of our new education initiatives aimed at improving uncertainty tolerance. We found that the PRU and PRA assessments were simple to administer and had a high completion rate. Our findings also suggest that individuals who identify with Judging may better tolerate the uncertainties associated with surgical practice, although larger studies will be required to determine if MBTI factors are linked to UI in surgical residents.

Assessing Callous-Unemotional Traits Using the Total Score from the Inventory of Callous-Unemotional Traits: A Meta-Analysis.

The Inventory of Callous-Unemotional Traits (ICU) is a widely used rating scale measure of callous-unemotional (CU) traits. Most studies have used a unit-weighted total score that sums all of the items into a composite, despite the consistent finding that items from this measure can be described using a bifactor model (1 general factor and 3 bifactors). We conducted a meta-analysis using the results of past published bifactor tests of the ICU, using indices to estimate the sources of variance in the total and subscale scores. We included studies in our review that tested and found adequate fit for the bifactor model of the ICU resulting in 12 published studies (M age = 9-26 from both community and justice-involved samples) using either the self-report (n = 9) or parent-report (n = 4) versions of the ICU scale (one published study conducted separate factor analyses for each version). We reported model-based reliability estimates that break down unit-weighted ICU scores into the variance due to individual differences in the general factor and the variance due to individual differences in the bifactors. The reliable variance in the unit-weighted total scale score of the ICU is largely determined by the general factor. Findings support the ICU total score as a measure of the general construct of CU traits, despite support for a bifactor model in multiple samples. Concerns about using the unit-weighted subscale scores from the ICU are raised since their reliable variance was strongly influenced by the general factor.

Adolescent Personality Pathology and the Alternative Model for Personality Disorders: Self Development as Nexus.

This paper reviews maladaptive trait development (DSM-5 Section III Criterion B), the development of DSM-5 Section II borderline personality disorder, and research on the development of identity, self-direction, empathy/mentalizing, and intimacy (DSM-5 Section III Criterion A). Combined, these previously disparate literatures begin to point to an integrated developmental theory of personality pathology, which suggests that Criterion A concepts (identity, self-direction, empathy, and intimacy) coalesce around the development of self, marking a discontinuous (qualitative) developmental shift. This developmental shift is a function of the demands placed on individuals to take on independent adult role function, combined with biologically-based maturational cognitive and emotional advances during adolescence. Section II personality disorder ensues when an integrated and coherent sense of self fails to develop, resulting in nonfulfilment of adult role function. In this sense, Criterion A self function can account for the onset of Section II personality disorder in adolescence, while Criterion B provides a useful descriptive account of continuous aspects of personality function over time.

Disinhibition and Detachment in Adolescence: A Developmental Cognitive Neuroscience Perspective on the Alternative Model for Personality Disorders.

Personality pathology often emerges during adolescence, but attempts to understand its neurocognitive basis have traditionally been undermined by problems associated with the categorical classification of personality disorders. In contrast, dimensional models of personality pathology, such as the Alternative Model for Personality Disorders (AMPD) in DSM-5, may provide a stronger foundation for neurobiological investigations of maladaptive individual differences in personality. As an example, we review studies of the adolescent development of reward processing and cognitive control and connect these systems to the normal personality hierarchy and to two dimensions included in the AMPD - Detachment and Disinhibition. We argue that by linking developmental changes in these systems to the AMPD, researchers will be better positioned to understand the relationship between neurocognitive development and the expression of personality pathology in adolescence and early adulthood.

The HEXACO-100 Across 16 Languages: A Large-Scale Test of Measurement Invariance.

The HEXACO Personality Inventory-Revised (HEXACO-PI-R) has become one of the most heavily applied measurement tools for the assessment of basic personality traits. Correspondingly, the inventory has been translated to many languages for use in cross-cultural research. However, formal tests examining whether the different language versions of the HEXACO-PI-R provide equivalent measures of the 6 personality dimensions are missing. We provide a large-scale test of measurement invariance of the 100-item version of the HEXACO-PI-R across 16 languages spoken in European and Asian countries (N = 30,484). Multigroup exploratory structural equation modeling and confirmatory factor analyses revealed consistent support for configural and metric invariance, thus implying that the factor structure of the HEXACO dimensions as well as the meaning of the latent HEXACO factors is comparable across languages. However, analyses did not show overall support for scalar invariance; that is, equivalence of facet intercepts. A complementary alignment analysis supported this pattern, but also revealed substantial heterogeneity in the level of (non)invariance across facets and factors. Overall, results imply that the HEXACO-PI-R provides largely comparable measurement of the HEXACO dimensions, although the lack of scalar invariance highlights the necessity for future research clarifying the interpretation of mean-level trait differences across countries.

Deprived and Grandiose Explanations for Psychological Entitlement: Implications for Theory and Measurement.

This work aimed to corroborate "vulnerable-based" and "grandiose-based" forms of psychological entitlement by amending the Psychological Entitlement Scale (PES; Campbell, Bonacci, Shelton, Exline, & Bushman, 2004), a popular unidimensional index of psychological entitlement. In 2 studies, participants completed PES items amended to include both deprived-identity-based and grandiose-identity-based rationales for item agreement and various individual-difference measures of constructs related to entitlement, self-evaluation, personality, and interpersonal orientations. The modified PES yielded a grandiose-based (PES-G) and vulnerable-based (PES-V) entitlement scale that showed good psychometric qualities. PES-G and PES-V converged well on core features of psychological entitlement (e.g., antagonistic outcomes) but generally failed to converge on self-evaluation, acquisitive versus defensive forms of entitlement, behavioral inhibition system and behavioral activation system, and interpersonal behavior indicative of claiming and cultivating grandiose versus deprived identities. This research supports the presence of grandiose-based and vulnerable-based entitlement forms, demonstrates a measurement technique to tap these forms, and suggests some theoretical implications.

Applicant Faking of Personality Inventories in College Admission: Applicants' Shift From Honest Responses Is Unsystematic and Related to the Perceived Relevance for the Profession.

This study aims to further our understanding of applicant faking twofold. First, it challenges viewing applicant faking as a systematic shift from otherwise honest responses. To this end, systematic item parameter shifts are proposed and tested across applicants and incumbents. Second, items' perceived relevance in a college admission process as real-life selection is scrutinized: Are applicants influenced by items' perceived relevance for the education, the prospective profession, or both? Participants (n = 840) filled out a Big Five inventory in a college admission process, and were retested 10 months later under standard instructions. Furthermore, they rated items' perceived relevancies for educational and professional purposes. Linear partial credit models were used to model item parameter shifts across response conditions. All proposed patterns of systematic shifts fit the data worse than unsystematic shifts. Unsystematic shifts were greater for lower response categories and items that were perceived as more relevant for the profession. The perceived relevance for education moderated the latter effect. Taken together, applicant faking should not be understood as applicants systematically shifting from their otherwise honest responses. Although applicants elevate their responses, it is not in a systematic way. Furthermore, determinants of applicant faking should be differentiated across real-life selection settings.

The Development and Validation of the Autotelic Personality Questionnaire.

Autotelic personality is a constellation of dispositional attributes that facilitate engagement and enjoyment in daily activities. However, there is no existing measurement directly capturing the attributes of autotelic personality that are identified in the literature. In the three studies reported here (total N = 900), we developed an Autotelic Personality Questionnaire (APQ) and evaluated its reliability and validity. Results from the studies provide support for adequate internal consistency, longitudinal invariance, and test-retest reliability (Study 1 and Study 2). Furthermore, APQ scores were significantly correlated with measures of conscientiousness, openness to experience, extraversion, neuroticism, and internal locus of control. In addition, APQ scores predicted flow proneness and satisfaction with life (Study 2). These results provide support for construct and criterion validity. Finally, people high in autotelic personality experienced more flow state than those low in autotelic personality during a word unscrambling task (Study 3), indicating good criterion validity of the APQ scores. Limitations, future research, and implications are discussed.

Clinical Utility of the Personality Assessment Inventory in Predicting Symptom Change and Clinical Outcome in an Inpatient Chemical Dependency Rehabilitation Unit.

Newly admitted inpatients in a 28-day chemical dependency rehabilitation unit completed the Personality Assessment Inventory (PAI) at admission and measures of clinical symptomatology (Symptom Checklist-90-Revised) and clinical outcome (Schwartz Outcome Scale-10) at admission and discharge. PAI drug and alcohol scale scores were clinically elevated in this inpatient sample. Modest elevations were found on scales measuring stress, depression, and antisocial and borderline features. Lower scores on most PAI clinical scales were associated with greater symptom reduction and improved psychological well-being, while controlling for pretreatment levels. Multivariate analysis controlling for contributions of clinical scales measuring borderline, depressive, and antisocial traits, as well as pretreatment outcome measures, demonstrated that the PAI Suicidal Ideation and Treatment Rejection scales were significant individual predictors of symptom reduction and improved psychological well-being, respectively, although the treatment scales as a group failed to incrementally contribute to prediction. Overall, the results support the clinical utility of using the PAI to predict clinical improvement among inpatients treated for substance use disorders.
