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.

Two-year retest reliability and predictive validity of the Self- and Informant-Personality Inventory for ICD-11 in older adults.

The International Classification of Diseases, 11th edition (ICD-11) adopted a fully dimensional model of personality disorder. The Personality Inventory for ICD-11 (PiCD) and Informant-Personality Inventory for ICD-11 (IPiC) were developed to assess the ICD-11 trait model, and the PiCD has since received significant validation support. However, there has only been one prior study of longitudinal predictive validity of the PiCD, two relatively short test-retest reliability studies of the PiCD, and no prior longitudinal tests of the IPiC. Longitudinal psychometric support for psychological assessment measures is essential. The present study provides a longer, larger, 2-year psychometric validation test of the PiCD and IPiC. Participants (N = 711) and their informants (N = 569) were recruited in the St. Louis Personality and Aging Network. The results demonstrated strong 2-year retest reliability for the PiCD and IPiC, as well as mean-level stability. Additionally, we explored the relationships between the PiCD and IPiC and important life outcome measures (depressive symptoms, satisfaction with life, and health status). The analysis revealed several significant associations between PiCD and IPiC scales and the outcome variables across time. Further, the PiCD Negative Affectivity and IPiC Detachment scales demonstrated incremental validity over each other and the outcome variables at Wave 1 in the prediction of depressive symptoms and satisfaction with life, respectively. The findings provide essential longitudinal test-retest reliability and predictive validity support for the PiCD and IPiC. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

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.

Measurement Invariance of the Pathological Narcissism Inventory and Multimethod Examination of Narcissistic Presentations in Community and Clinical Samples.

The Pathological Narcissism Inventory (PNI) is extensively used in recent empirical literature on pathological narcissism. However, most studies using the PNI are community-based, and no studies have used the PNI to investigate narcissistic presentations in personality disordered patients. This study investigates measurement invariance of the PNI in community participants and patients with personality disorders, and examines differences of narcissistic presentations in these samples through a multimethod approach. Results show that the PNI can be used reliably to measure and compare traits of pathological narcissism in community participants and patients with personality disorders. Personality disordered patients show higher traits reflecting vulnerable narcissism and overt manifestations of grandiose narcissism, compared with controls. Finally, network analysis indicates that traits of grandiose fantasies and entitlement rage have a central role in defining manifestations of PNI pathological narcissism, regardless of the presence of an underlying personality disorder. Research and clinical implications are discussed.

Test-retest reliability of the HEXACO-100-And the value of multiple measurements for assessing reliability.

Despite the widespread use of the HEXACO model as a descriptive taxonomy of personality traits, there remains limited information on the test-retest reliability of its commonly-used inventories. Studies typically report internal consistency estimates, such as alpha or omega, but there are good reasons to believe that these do not accurately assess reliability. We report 13-day test-retest correlations of the 100- and 60-item English HEXACO Personality Inventory-Revised (HEXACO-100 and HEXACO-60) domains, facets, and items. In order to test the validity of test-retest reliability, we then compare these estimates to correlations between self- and informant-reports (i.e., cross-rater agreement), a widely-used validity criterion. Median estimates of test-retest reliability were .88, .81, and .65 (N = 416) for domains, facets, and items, respectively. Facets' and items' test-retest reliabilities were highly correlated with their cross-rater agreement estimates, whereas internal consistencies were not. Overall, the HEXACO Personality Inventory-Revised demonstrates test-retest reliability similar to other contemporary measures. We recommend that short-term retest reliability should be routinely calculated to assess reliability.

Validation and psychometric properties of the Brazilian-Portuguese dispositional flow scale 2 (DFS-BR).

INTRODUCTION: Flow state is a psychological concept used to describe the optimal engagement in different activities. Therefore, the DFS-2 has been developed as an instrument to measure an individual's dispositional tendency to flow state as a personality trait. OBJECTIVE: Aiming to obtain an adapted version of the DFS-2 for the Brazilian-Portuguese language (DFS-BR) and for general activities, we performed its forward- and backward-translation, and we validated it. METHODS: After gathering answers from 681 Brazilian participants, we performed: (1) the construct validity of the DFS-BR; and (2) the psychometric item quality analysis. RESULTS: the Confirmatory Factorial Analysis (CFA) indicates the best fit for the gathered data is a nine multi-correlated factorial model (χ2/df = 4.23, CFI = 0.94, TLI = 0.93 and RMSEA = 0.069). Reliability tests performed in this structure indicates excellent internal consistency for the DFS-BR. The item quality analysis indicates that its difficulty and discriminating parameters have a good endorsement to estimate the dispositional flow state. Additionally, we proposed and validated a short version of the DFS-BR (composed of only nine items). The validation results indicates good fit (χ2/df = 2.94, CFI = 0.98, TLI = 0.97 and RMSEA = 0.053) and good internal consistency. The Test Information Curve of the short version indicates that it is very informative in the estimation of individual dispositional flow state. DISCUSSION AND CONCLUSIONS: In view of these results, we conclude that the DFS-BR showed good evidence of its validity to be used with Brazilian people. We also suggest the use of a short version when we need only measure the person's flow state based on the principle of Occam's razor. This principle is supported by the analysis presented in this article.

Resilience matters: Explaining the association between personality and psychological functioning during the COVID-19 pandemic / La resiliencia importa: explicación de la asociación entre personalidad y funcionamiento psicológico durante la pandemia de COVID-19

BACKGROUND/OBJECTIVE: The objective of the study was to elucidate the underlying mechanism through which basic personality dimensions predict indicators of psychological functioning during the COVID-19 pandemic, including subjective well-being and perceived stress. As a personality characteristic highly contextualized in stressful circumstances, resilience was expected to have a mediating role in this relationship. METHOD: A sample of 2,722 Slovene adults, aged from 18 to 82 years filled in the Big Five Inventory, the Connor-Davidson Resilience Scale, the Perceived Stress Scale, and the Mental Health Continuum. A path analysis with the Bootstrap estimation procedure was performed to evaluate the mediating effect of resilience in the relationship between personality and psychological functioning. RESULTS: Resilience fully or partially mediated the relationships between all the Big Five but extraversion with subjective well-being and stress experienced at the beginning of the COVID-19 outburst. Neuroticism was the strongest predictor of less adaptive psychological functioning both directly and through diminished resilience. CONCLUSIONS: Resilience may be a major protective factor required for an adaptive response of an individual in stressful situations such as pandemic and the associated lockdown

ANTECEDENTES/OBJETIVO: El objetivo fue dilucidar el mecanismo subyacente a través del cual las dimensiones básicas de la personalidad predicen indicadores del funcionamiento psicológico durante la pandemia de COVID-19, incluido el bienestar subjetivo y el estrés percibido. Como característica de la personalidad altamente contextualizada en circunstancias estresantes, se esperaba que la resiliencia tuviera un papel mediador en esta relación. MÉTODO: Una muestra de 2.722 adultos eslovenos (18-82 años), completó el Big Five Inventory, la Connor-Davidson Resilience Scale, la Perceived Stress Scale y el Mental Health Continuum. Se realizó un análisis de ruta con el procedimiento de estimación Bootstrap para evaluar el efecto mediador de la resiliencia en la relación entre la personalidad y el funcionamiento psicológico. RESULTADOS: La resiliencia medió total o parcialmente las relaciones entre los Cinco Grandes, y la extraversión con bienestar subjetivo y el estrés experimentado, al comienzo del estallido de COVID-19. El neuroticismo fue el predictor más fuerte de un funcionamiento psicológico menos adaptativo, tanto directamente como a través de la disminución de la capacidad de resiliencia. CONCLUSIONES: La resiliencia puede ser un factor de protección importante y requerido para una respuesta adaptativa de un individuo en situaciones estresantes como la pandemia y el confinamiento asociado

Psychometric properties and normative information on the child and adolescent behavior inventory with ratings for Spanish children from parents and teachers / Información Psicométrica y Normativa del Child and Adolescent Behavior Inventory con Evaluaciones de Madres, Padres y Maestros de Niños Españoles

BACKGROUND: Psychometric properties and initial normative information are provided for the sluggish cognitive tempo, attention-deficit/hyperactivity disorder-inattention, attention-deficit/hyperactivity disorder-hyperactivity/impulsivity, oppositional defiant disorder, callous-unemotional behavior (limited prosocial emotions specifier), anxiety, depression, social impairment, and academic impairment scales of the Spanish Child and Adolescent Behavior Inventory. METHOD: Mothers, fathers, and teachers of 2,142 third to sixth grade Spanish children (49.49% girls; ages 8-13) from randomly selected schools on the Balearic Islands completed the Child and Adolescent Behavior Inventory. RESULTS: Scores from the scales demonstrated reliability (internal consistency and inter-rater), structural validity, and convergent/discriminant validity with attention-deficit/hyperactivity disorder and learning disorder diagnoses for boys and girls separately for each source. Normative information (T-scores) is provided for the nine scales separately for boys and girls, with test information functions supporting use of the symptom scales for screening purposes. CONCLUSIONS: Although more comprehensive Spanish norms are still needed, the initial normative information on the scales should be useful to inform the clinical care of individual Spanish children, with the positive psychometric properties of the scores also supporting the use of the scale for research. Copies of the Spanish Child and Adolescent Behavior Inventory and norms are available for free to clinicians and researchers

ANTECEDENTES: en este trabajo se presenta información psicométrica y normativa inicial de la versión española del Child and Adolescent Behavior Inventory para las escalas: tempo cognitivo lento, inatención e hiperactividad/impulsividad del trastorno por déficit de atención e hiperactividad, negativismo desafiante, dureza emocional, ansiedad, depresión, afectación social y deterioro académico. MÉTODO: una muestra de madres, padres y maestros de 2.142 niños españoles de tercer a sexto curso de escuelas seleccionadas al azar en las Islas Baleares completaron el Child and Adolescent Behavior Inventory. RESULTADOS: las puntuaciones de las escalas demostraron fiabilidad, validez estructural y validez de criterio con diagnósticos de TDAH y de trastornos del aprendizaje para niños y niñas. Se proporciona información normativa para las nueve escalas por separado para niños y niñas, mientras las funciones de información del test han respaldado el uso de las escalas de síntomas para fines de detección inicial. CONCLUSIONES: aunque todavía son necesarios datos normativos más completos en niños de muestras españolas, la información normativa inicial que proporcionamos de las escalas CABI debería ser útil para los informes en el ámbito clínico, además los datos psicométricos positivos de sus puntuaciones también apoyan su uso en investigación

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.

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.

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.

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.

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.

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.

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.

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.

The Development and Preliminary Psychometric Evaluation of the Theory of Mind Inventory: Self Report-Adult (ToMI:SR-Adult).

This study describes the development and psychometric evaluation of a new self-report measure of social cognition: the Theory of Mind Inventory:Self-report-Adult (ToMI:SR-Adult). Adults with autism (or a suspicion of autism; n = 111) and typically developing adults (n = 109) completed a demographic questionnaire and the ToMI:SR-Adult online. Both quantitative and qualitative self-reports of one's own theory of mind functioning were collected. The ToMI:SR-Adult performed well under all examinations of reliability and validity (internal consistency, accuracy of classification, contrasting-groups). The qualitative data confirmed impressions of validity and revealed that the adults in our sample had high levels of self-insight regarding their own theory of mind. The ToMI:SR-Adult is offered as a promising research and clinical tool for the assessment of social cognition in adults.

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.

A dimensional measure of schizotypy: cross-cultural adaptation and validation of the Oxford-Liverpool Inventory of Feelings and Experiences short version for Brazilian Portuguese (O-LIFE-S)

Abstract Introduction The Oxford-Liverpool Inventory of Feelings and Experiences (O-LIFE) is a widely-used scale, and the first to include a dimensional approach to understanding schizotypy. Objective To adapt the short version of the O-LIFE (O-LIFE-S) into Brazilian Portuguese. Method a) Two independent bilingual professionals translated the original instrument into Brazilian Portuguese; b) a third bilingual professional summarized the two translations; c) a fourth bilingual expert translated the Portuguese version back into English; d) this back-translation was adjusted by a committee of psychology experts; e) a pilot study was conducted with 10 participants from the general population. Results O-LIFE-S was considered ready to be used in a formal validation study in Brazil. Conclusion The scale appears to cover the dimensional approach to schizotypy. However, a future validation study needs to be conducted to determine the internal consistency and reliability of the Brazilian Portuguese version of the O-LIFE-S .

Translation and cultural adaptation of the DSM-5 Personality Inventory - Brief Form (PID-5-BF)

Abstract Introduction The Personality Inventory for the DSM-5 - Brief Form (PID-5-BF) - is an instrument for assessment of the five pathological personality traits from the Diagnostic and Statistical Manual of Mental Disorders, 5th edition (DSM-5) alternative model of personality disorders. Objectives To determine the psychometric properties of the version of the PID-5-BF translated and adapted to Brazilian Portuguese. Methods The process of translating and cross-culturally adapting the text was carried out by independent translators and the resulting version was administered to 176 patients in two hospitals in Rio Grande do Sul. The internal structure was tested by means of confirmatory factor analysis. Evidence of reliability was tested by examining the internal consistency of the scales and their convergent and concurrent validity with other methods of psychopathology. Results The five factors were replicated in the present sample with adequate indicators of fit of the data to the model. Appropriate reliability coefficients for the scales and evidence of validity were observed, indicating the clinical usefulness of the PID-5-BF in the Brazilian context. Conclusion The psychometric properties of PID-5-BF proved satisfactory in an initial sample of Brazilians.
