Cross-cultural investigation from nine countries on the associations of antisocial traits and the WHO's containment measures for the COVID-19 pandemic.

Personality traits play a role in prosocial behavior in relation to containment measures intended to tackle the COVID-19 pandemic. Empirical findings indicated that individuals high in socially aversive traits such as callousness are less compliant with containment measures. This study aimed to add cross-cultural data on the relationship between antisocial traits and adherence to COVID-19 containment measures. The sample consisted of 4,538 adults recruited by convenience in nine countries (Australia, Brazil, England, Iraq, Iran, Italy, Jordan, Saudi Arabia, and the United States). Statistical analyses indicated two latent profiles from our sample, empathic and antisocial, and six COVID-19 containment-measure-related factors using measures covering antisocial traits (PID-5), empathy (ACME), global personality pathology (LPFS-BF), and COVID-19 behaviors and beliefs. Through MANCOVA, the antisocial profile consistently showed less compliance and concern about the COVID-19 containment measures, even when controlling for demographics and local pandemic covariables. The network analysis indicated a lack of empathy and callousness as crucial traits of the predisposition to non-compliant behavior. In elaborating on prosocial campaigns in community emergencies, our cross-cultural findings would need to consider personality traits that focus on antisociality, anticipating similar associations and potential impacts in future disease outbreaks.

Preliminary findings on the associations between personality traits and engagement behavior to the COVID-19 containment measures.

In March 2020, the World Health Organization (WHO) had declared the coronavirus disease 2019 (COVID-19) pandemic. Three weeks after WHO's declaration, almost 900,000 cases of COVID-19 were confirmed, with more than 43,000 deaths worldwide. Containment measures were recommended, such as social distancing and hand hygiene. Although they are known to be helpful to slow down the spread of the COVID-19, the efficiency of these measures depends on people's adherence. We explore whether personality traits account for variations in the commitment to the COVID-19 containment measures. The sample consisted of 814 Brazilian adults who answered a questionnaire about adherence to COVID-19 containment measures (COVID-19 questionnaire), factors of the Personality Inventory for DSM-5 (PID-5), and the affective resonance factor of the Affective and Cognitive Measure of Empathy (ACME). We conducted a network analysis. All connections observed in the network analysis were significant (p < .05). Empathy was the personality trait to present more connections to the COVID-19 questionnaire variables. The strongest positive connection was observed for emotional lability (PID-5) and the tendency to be concern about others getting the COVID-19 (COVID-19 questionnaire). Our findings indicated that empathy and emotional lability might be key traits directly associated with the propensity to adhere to the COVID-19 containment measures.

Compliance with containment measures to the COVID-19 pandemic over time: Do antisocial traits matter?

This study investigated the relationships between antisocial traits and compliance with COVID-19 containment measures. The sample consisted of 1578 Brazilian adults aged 18-73 years who answered facets from the PID-5, the Affective resonance factor of the ACME, and a questionnaire about compliance with containment measures. Latent profile analyses indicated a 2-profile solution: the antisocial pattern profile which presented higher scores in Callousness, Deceitfulness, Hostility, Impulsivity, Irresponsibility, Manipulativeness, and Risk-taking, as well as lower scores in Affective resonance; and the empathy pattern profile which presented higher scores in Affective resonance and lower scores in ASPD typical traits. The latent profile groups showed significant differences between them and interaction with the containment measures and weeks. The antisocial and empathy groups showed significant differences. These differences were sustained in the interaction with the containment measures and weeks separately, but not when all were interacting together. Our findings indicated that antisocial traits, especially lower levels of empathy and higher levels of Callousness, Deceitfulness, and Risk-taking, are directly associated with lower compliance with containment measures. These traits explain, at least partially, the reason why people continue not adhering to the containment measures even with increasing numbers of cases and deaths.

Does the Rorschach Performance Assessment System (R-PAS) Differ from the Comprehensive System (CS) on Variables Relevant to Interpretation?

We examined the impact of the changes in administration and coding introduced by the Rorschach Performance Assessment System (R-PAS) relative to the Comprehensive System (CS) on the Rorschach response process, as manifested in variables relevant to interpretation. We also examined the efficiency of each system to obtain protocols in an optimal range of responses (R) for interpretation. As hypothesized, when comparing 50 CS and 50 R-PAS nonpatient protocols, R-PAS produced many more protocols in the optimal R range (18-27) than the CS (78% vs. 24%) and it eliminated the need for re-administration, which was required for five CS protocols. As expected, R was less variable with R-PAS, as were two variables derived from it, R8910% and Complexity. In addition, as expected because of different Form Quality tables, R-PAS showed notably fewer and less variable perceptual distortions than the CS, and an increase in more conventional perceptions. The other 58 variables showed no reliable differences in means or standard deviations, though modest power precluded definitive inferences about equivalence. Overall, our results support previous findings about the benefit of R-PAS to obtain protocols in an optimal range for interpretation, while keeping the core manifestations of the response process unchanged.

Measuring pathological traits of the schizotypal personality disorder through the HiTOP model.

Schizotypal personality disorder (STPD) is characterized by difficulties in intimate relationships, social and interpersonal deficits, and perceptual distortions. Encompassing this personality disorder and other mental conditions, the Hierarchical taxonomy of psychopathology (HiTOP) is an evidence-based, dimensional model covering pathological traits in its lower range. This study aimed to develop a self-report scale for screening pathological traits of STPD from the perspective of the HiTOP. The sample consisted of 474 Brazilian adults aged 18-70 years who answered the developed scale, the IDCP-STPD, facets of the Personality Inventory for DSM-5 (PID-5), and factors of the Computerized Adaptive Assessment of Personality Disorder Static Form (CAT-PD-SF). The scale was composed of 73 items distributed in two factors. Internal structure reliability was higher than 0.80 for all scores of the scale. The factors showed associations with the expected external measures, and the groups based on the STPD external measures (healthy and pathological) showed big to huge differences. Although initial, our findings suggested the IDCP-STPD as a helpful measure to the clinical context to screen the STPD pathological traits. Moreover, the structure observed for the IDCP-STPD confirms the spectrum level of the HiTOP.

Dimensional clinical personality inventory-2: investigating key factors on the assessment of dependent personality disorder.

Dimensional literature reinforces the relevance of specific Dependent personality disorder (DPD) traits, as submissiveness, insecurity and avoidance of abandonment. In this paper we measured these traits through the Dimensional Clinical Personality Inventory-2 (IDCP-2). This study aims to verify the capacity of IDCP-2 factors to discriminate and predict DPD related symptoms. From a dataset with 4,503, a total of 305 people was divided in three groups: the community group (n = 200), the non-DPD group (N = 84), and the DPD group (n = 21). We administered six factors from IDCP-2, Insecurity, Abandonment Avoidance, Self-devaluation, Submissiveness, Masochism, and Self-driven Hopelessness. Groups comparison were significant, showing high effects in mostly cases. Multiple regression analysis showed the best predictors of the groups, i.e. Abandonment Avoidance and Self-driven Hopelessness. The findings of this study demonstrate that IDCP-2 covers the core traits of DPD, therefore, being a valid and applicable measure to discriminate DPD, which is particularly relevant in clinical settings. Although our findings suggested two factors as the most relevant measures to discriminant DPD patients from non-DPD/community samples, we did not suggest the restrict use of the Abandonment Avoidance and Self-driven Hopelessness factors for DPD screening. Limitations of the study were discussed.

Potential Projective Material on the Rorschach: Comparing Comprehensive System Protocols to Their Modeled R-Optimized Administration Counterparts.

Exner ( 1989 ) and Weiner ( 2003 ) identified 3 types of Rorschach codes that are most likely to contain personally relevant projective material: Distortions, Movement, and Embellishments. We examine how often these types of codes occur in normative data and whether their frequency changes for the 1st, 2nd, 3rd, 4th, or last response to a card. We also examine the impact on these variables of the Rorschach Performance Assessment System's (R-PAS) statistical modeling procedures that convert the distribution of responses (R) from Comprehensive System (CS) administered protocols to match the distribution of R found in protocols obtained using R-optimized administration guidelines. In 2 normative reference databases, the results indicated that about 40% of responses (M = 39.25) have 1 type of code, 15% have 2 types, and 1.5% have all 3 types, with frequencies not changing by response number. In addition, there were no mean differences in the original CS and R-optimized modeled records (M Cohen's d = -0.04 in both databases). When considered alongside findings showing minimal differences between the protocols of people randomly assigned to CS or R-optimized administration, the data suggest R-optimized administration should not alter the extent to which potential projective material is present in a Rorschach protocol.

The Impact of R-Optimized Administration Modeling Procedures on Brazilian Normative Reference Values for Rorschach Scores.

To generate normative reference data for the Rorschach Performance Assessment System (R-PAS), modeling procedures were developed to convert the distribution of responses (R) in protocols obtained using Comprehensive System (CS; Exner 2003 ) administration guidelines to match the distribution of R in protocols obtained using R-Optimized Administration (Meyer, Viglione, Mihura, Erard, & Erdberg, 2011 ). This study replicates the R-PAS study, examining the impact of modeling R-Optimized Administration on Brazilian normative reference values by comparing a sample of 746 CS administered protocols to its counterpart sample of 343 records modeled to match R-Optimized Administration. The results were strongly consistent with the R-PAS findings, showing the modeled records had a slightly higher mean R and, secondarily, slightly higher means for Complexity and V-Comp, as well as smaller standard deviations for R, Complexity, and R8910%. We also observed 5 other small differences not observed in the R-PAS study. However, when comparing effect sizes for the differences in means and standard deviations observed in this study to the differences found in the R-PAS study, the results were virtually identical. These findings suggest that using R-Optimized Administration in Brazil might produce normative results that are similar to traditional CS norms for Brazil and similar to the international norms used in R-PAS.

Development and Validation of Dimensional Clinical Personality Inventory 2 (IDCP-2) Algorithms to Assess ICD-11 Personality Trait Domain Qualifiers.

With the advent of the new diagnostic model for personality disorders in the 11th revision of the International Classification of Diseases (ICD-11), researchers and practitioners in World Health Organization signatory countries are urged to implement it. This study aims to develop a brief, reliable, and valid scale for assessing maladaptive personality traits according to the ICD-11 model, using the item pool of the Dimensional Clinical Personality Inventory (IDCP-2). Quantitative and qualitative criteria for item selection were applied to a sample of 251 Brazilian adults. As a result, the 25 items (five items per factor) were selected, demonstrating promising evidence of validity based on the internal structure with a database of 1,659 Brazilian adults. In addition, we found good evidence of validity based on relationships with external variables, particularly those related to personality pathology, in a sample of 617 Brazilian adults. The implications of these findings are discussed.

Antisocial personality traits relationship with behaviours and beliefs on COVID-19 containment measures: Investigation in a large Brazilian sample.

In the COVID-19 context, traits associated with antisociality can decrease concern and awareness about the potential harmfulness of the virus. This study investigated associations of pathological traits of antisocial personality disorder (ASPD) with behaviours and beliefs linked to COVID-19 containment measures. The sample consisted of 2230 Brazilian adults who answered ASPD-related facets of the Personality Inventory for DSM-5 and a questionnaire regarding adherence to COVID-19 containment measures. We applied the DSM-5 ASPD criteria to divide the sample into antisocial and non-antisocial groups. Our findings suggest that individuals meeting the criteria for ASPD tend to exhibit reduced compliance with pandemic control measures and lower adherence to hygiene practices. Moreover, sex, income, and age should be considered potential covariates in research investigating the relationship between antisocial traits and adherence to COVID-19 preventive measures. Altogether, our findings highlight ASPD traits' role in the predisposition to lack of prosocial behaviours of adherence to COVID-19 containment measures.

Comparing the Validity of the Rorschach Performance Assessment System and Exner's Comprehensive System to Differentiate Patients and Nonpatients.

Building on the comparative nonpatient study of Pianowski et al., we examine data from the Rorschach Performance Assessment System (R-PAS) and Comprehensive System (CS) in 100 nonpatients and 100 patients, 50 of each per system. Replicating their results but now in a patient sample, R-PAS produced more patient protocols having an optimal number of responses (R) for interpretation and eliminated the need for readministration due to low R. The R-PAS protocols were also much less variable in R, despite having about 2.5 more responses. Extending their results, we document that the primary markers of psychopathology in each system validly differentiate patients from nonpatients. However, R-PAS produced stronger effects. Finally, Complexity added to the valid discrimination of patients from nonpatients just for R-PAS, with patients producing less complex and rich records. The more erratic variability in R for the CS produced larger Complexity standard deviations (SDs) that obscured these genuine differences in people. We discuss implications for research and applied practice, along with directions for future research.

Inventory of Interpersonal Problems-Personality Disorders: adaptation to Brazil and test of a bifactor model.

OBJECTIVE: The Inventory of Interpersonal Problems-Personality Disorders (IIP-PD-47) has a controversial factor structure, as some studies have provided support for 5 correlated factors, and others have suggested the existence of a general second-order dimension. One approach of data modelling that reconciles multidimensionality and the existence of a general factor is the bifactor analysis. We used unrestricted exploratory-confirmatory bifactor modelling to validate the Brazilian version of the IIP-PD-47. METHODS: The sample consisted of 1,091 subjects aged 18-64 years who answered the IIP-PD-47 and a collateral measure of pathological traits, the Dimensional Clinical Personality Inventory 2 (IDCP-2). RESULTS: After testing many candidate models, our data were best represented by a bifactor model with one general factor and five specific uncorrelated factors. Nevertheless, a closer inspection of the discriminant validity of each IIP-PD-47 factor revealed strong support for the general factor and a factor capturing aggressive behaviours, but less support for the additional four specific factors. CONCLUSIONS: The theoretical and practical implications of these findings are discussed, and some recommendations are offered about the need for controlling response styles when assessing PD traits via self-report inventories. Our findings indicate that the Brazilian version of IIP-PD has promising psychometric properties.

Personality differences and COVID-19: are extroversion and conscientiousness personality traits associated with engagement with containment measures?

Introduction In December 2019, an outbreak of the novel coronavirus, the coronavirus disease 2019 (COVID-19) probably occurred in Wuhan, China. By March 2020, the World Health Organization (WHO) had declared a pandemic. Containment measures such as social distancing and hand hygiene were recommended. In this study, we start from the hypothesis that engaging with containment measures in a pandemic situation should be more comfortable for some people than for other people. Thus, individual differences should be associated with engagement with containment measures. Objective To investigate to what extent two personality traits, extroversion and conscientiousness, are associated with engagement with two containment measures (social distancing and handwashing). Methods The sample consisted of 715 Brazilian adults aged 18-78 years, who answered the Big Five Inventory 2 Short (BFI-2-S) and factors from the Dimensional Clinical Personality Inventory 2 (IDCP-2). Results Higher scores for extroversion were associated with lower means for social distancing (p < 0.001) and higher scores for conscientiousness were associated with higher means for social distancing and handwashing (p < 0.05). Conclusion The findings indicate the importance of acknowledging extroversion and conscientiousness traits as relevant to people's engagement with the measures recommended for COVID-19 containment.

Relationship between religiosity domains and traits from borderline and schizotypal personality disorders in a Brazilian community sample.

INTRODUCTION: Research suggests that religiosity domains are associated with mental health constructs. Some studies have focused on the relationship between religiosity and personality disorders. OBJECTIVE: To investigate the relationship between religiosity domains and pathological traits of the borderline (BPD) and schizotypal (SZPD) personality disorders. METHODS: Participants were 751 adults from the general population who answered the Multidimensional Inventory for Religious/Spiritual Well-Being (MI-RSWB-E), the Attachment to God Inventory (AGI), and factors of the Dimensional Clinical Personality Inventory 2 (IDCP-2). Pearson's correlation and regression analysis were conducted with pathological traits as independent variables and religiosity domains as dependent variables. RESULTS: Correlation and regression analyses indicated slightly higher associations between religiosity domain and BPD traits in comparison to SZPD traits. BPD traits showed higher associations with the hope immanent, forgiveness and hope transcendent domains, while SZPD presented higher associations with connectedness. The SZPD-related paranormality factor presented the highest correlation observed in the study and was the best SZPD predictor of religiosity domains. The BPD-related hopelessness factor was the predictor with significant contribution to most regression models. BPD traits presented slightly higher average association with religiosity domains, whereas spiritual-related domains (e.g., connectedness) tended to show higher associations with SZPD traits. CONCLUSIONS: Our findings help explain the relationship between specific pathological traits and religiosity domains.

Dependency, mood instability, and inconsequence traits for discriminating borderline personality disorder.

INTRODUCTION: Borderline personality disorder (BPD) is one of the most widely studied personality disorders (PDs). It recurrently shows traits of emotional lability, anxiety, separation insecurity, depressiveness, impulsiveness, risk exposure, and hostility, mainly affecting the domains of negative affectivity and antagonism. OBJECTIVES: To investigate the most discriminant dimensions of the Dimensional Clinical Personality Inventory (Inventário Dimensional Clínico da Personalidade 2 [IDCP-2]) to distinguish people diagnosed with BPD from people without this diagnosis. METHODS: A total of 305 participants were included in this study: psychiatric outpatients diagnosed with BPD (n = 30), psychiatric outpatients diagnosed with other PDs (n = 75), and a community sample (n = 200). BPD traits were assessed using the dependency, mood instability, and inconsequence dimensions of the IDCP-2. RESULTS: Analysis of variance (ANOVA) comparisons indicated highest mean measures in the BPD group, and mood instability factors were the most discriminant ones when considering all groups. Applying the multiple regression analysis, we found an adjusted r 2 = 0.50, and hopelessness was the most predictive measure (ß = 0.32; t = 6.19; p < 0.001). CONCLUSIONS: We found discriminatory capacity for factors of all dimensions, although at different levels, and more consistent results to discriminate the BPD group from the community sample.

Investigating Correlations Between Defence Mechanisms and Pathological Personality Characteristics.

INTRODUCTION: The purpose of this study was to investigate the relationship between defence mechanisms and pathological personality traits. MATERIAL AND METHODS: We analysed 320 participants aged from 18 to 64 years (70.6% women, 87.5% university students) who completed the Dimensional Clinical Personality Inventory (IDCP) and the Defence Style Questionnaire (DSQ-40). We conducted comparisons and correlations and a regression analysis. RESULTS: The results showed expressive differences (d>1.0) between mature, neurotic and immature defence mechanism groups, and it was observed that pathological personality traits are more typical in people who use less mature defence mechanisms (i.e., neurotic and immature), which comprises marked personality profiles for each group, according to the IDCP. We also found correlations between some of the 40 specific mechanisms of the DSQ-40 and the 12 dimensions of pathological personality traits from the IDCP (r ≥ 0.30 to r ≤ 0.43), partially supported by the literature. In addition, we used regression analysis to verify the potential of the IDCP dimension clusters (related to personality disorders) to predict defence mechanisms, revealing some minimally expressive predictive values (between 20% and 35%). DISCUSSION: The results indicate that those who tend to use immature defence mechanisms are also those most likely to present pathological personality traits. CONCLUSIONS: The findings indicate the importance of investigating these correlations as a possible improvement to clinical assessment and intervention.

Investigating the Spectra constellations of the Hierarchical Taxonomy of Psychopathology (HiTOP) model for personality disorders based on empirical data from a community sample.

OBJECTIVE: The Hierarchical Taxonomy of Psychopathology (HiTOP) posits that psychopathology is hierarchically structured. For personality disorder (PD) traits, there are five spectra: internalizing, thought disorder, disinhibited externalizing, antagonistic externalizing, and detachment. Empirical findings suggest a sixth group, compulsivity. In this research, we tried to recover the five HiTOP spectra, plus compulsivity, specifically for PD traits. METHODS: The sample was composed of 4,868 Brazilians (54.9% women, age ranging from 18 to 70; mean = 25.7; SD = 9.64). All participants answered the Dimensional Clinical Personality Inventory 2 (IDCP-2), a self-report inventory for adults, developed in Brazil, for assessment of pathological personality traits. RESULTS: Parallel analysis yielded up to nine factors. On exploratory structural equation modeling (E-SEM), the balance between interpretability and fit index suggested the six-factor solution as the best solution. The fit indexes for the confirmatory factor analysis were slightly less adjusted in comparison to the empirical model. CONCLUSION: The hypothesis was confirmed, as we did find the groups proposed at the spectrum level of the HiTOP. We also found a compulsivity factor, encompassing the main traits from the conscientiousness dimension of IDCP-2, which is related to obsessive-compulsive PD. Finding the six groupings of traits in the HiTOP model contributes to the validity of this model, and confirms the existence of proposed spectra.

Teaching differential diagnosis with Anakin Skywalker: the duel between borderline personality disorder and bipolar disorder / Ensinando diagnóstico diferencial com Anakin Skywalker: o duelo entre transtorno da personalidade borderline e transtorno bipolar

Objective: Previous publications have focused on a leading pop culture phenomenon, Star Wars, to teach several issues in psychiatry, which can make understanding challenging themes easier. This article delves into matters of differential diagnoses regarding two psychiatric disorders. Methods: We examine and compare the symptoms and specificities of borderline personality disorder and bipolar disorder in the light of the fictional villain of the films, Darth Vader/Anakin Skywalker. Results and Conclusion: Our considerations of his diagnosis should be interpreted as an academic exercise with two main goals: to discuss the differential diagnosis between borderline personality disorder and bipolar disorder in an illustrative, soft, and ludic way; and to teach how to connect one's behaviors with diagnostic criteria - in this case, those related to borderline personality disorder.

Objetivo: Publicações de outrora utilizaram um dos principais fenômenos da cultura pop, Star Wars, para ensinar diversas questões sobre psiquiatria, demonstrando que usar os filmes da série para ensinar tais assuntos pode facilitar a compreensão de temas desafiadores. O objetivo deste artigo é aprofundar as questões do diagnóstico diferencial de dois transtornos psiquiátricos. Métodos: Nós examinamos e comparamos as especificidades do transtorno de personalidade borderline e transtorno bipolar à luz do personagem fictício dos filmes Star Wars, o vilão Darth Vader/Anakin Skywalker. Resultados e Conclusão: As considerações sobre o diagnóstico de Darth Vader devem ser interpretadas como um exercício acadêmico com dois objetivos principais: discutir o diagnóstico diferencial entre transtorno de personalidade borderline e transtorno bipolar de forma ilustrativa, suave e lúdica; e ensinar como relacionar os comportamentos com critérios diagnósticos, neste caso, especificamente relacionados ao transtorno de personalidade borderline.

Inventory of Interpersonal Problems-Personality Disorders: adaptation to Brazil and test of a bifactor model

Objective: The Inventory of Interpersonal Problems-Personality Disorders (IIP-PD-47) has a controversial factor structure, as some studies have provided support for 5 correlated factors, and others have suggested the existence of a general second-order dimension. One approach of data modelling that reconciles multidimensionality and the existence of a general factor is the bifactor analysis.

Objetivo: El Inventario de Problemas Interpersonales-Trastornos de la Personalidad (IIP-PD-47) tiene una estructura factorial controvertida, ya que algunos estudios han apoyado 5 factores correlacionados y otros han sen˜ alado la existencia de una dimensión general de segundo orden. Un enfoque del modelado de datos que concilia la multidimensionalidad y la existencia de un factor general es el análisis de bifactores. Para validar la versión brasileña del IIP-PD-47, se utilizó un modelo bifactorial confirmatorio exploratorio sin restricciones. Métodos: La muestra incluyó a 1.091 sujetos de 18 a 64 anos que respondieron al IIP-PD-47 y una medida colateral de rasgos patológicos, el Inventario de Personalidad Clínica Dimensional 2 (IDCP-2). Resultados: Después de probar muchos modelos candidatos, nuestros datos se representaron mejor mediante un modelo bifactorial con 1 factor general y 5 factores específicos no correlacionados. Sin embargo, una inspección más cercana de la validez discriminante de cada factor IIP-PD-47 reveló un fuerte respaldo del factor general y un factor que capta comportamientos agresivos, pero menos respaldo a los 4 factores específicos adicionales. Conclusiones: Se discuten las implicaciones teóricas y prácticas de estos hallazgos y se ofrecen algunas recomendaciones sobre la necesidad de controlar los estilos de respuesta al evaluar los rasgos de la EP a través de inventarios de autoaplicados. Nuestros hallazgos indican que la versión brasileña de IIP-PD tiene propiedades psicométricas prometedoras.
