ABSTRACT
Abstract The aim of this study was to develop a version of the Dimensional Clinical Personality Inventory 2 (IDCP-2) focusing on the Histrionic Personality Disorder (HPD) traits according to the Hierarchical Taxonomy of Psychopathology (HiTOP) model, and to verify its psychometric properties. The method was divided into two stages. The first was related to the revision procedures of the IDCP-2 based on the HiTOP, focusing on the assessment of features typical of HPD. The second aimed to verify the psychometric properties of the new version of the IDCP-2 (i.e., IDCP-HPD) in a convenience sample (N=208), mainly composed of women, with data collection carried out online. The IDCP-HPD was administered with the Personality Inventory for DSM-5 (PID-5) and Five-Factor Histrionic Inventory (FFHI) factors. Of the 16 initial traits provided by the HiTOP, 8 were selected as relevant for the HPD and 17 items were selected to compose the new factors. The 4 factor solution found through exploratory structural equation modeling, the correlations with the external measures and the effects found in the between-group comparisons suggest the psychometric adequacy of the IDCP-HPD. The findings of this study should be interpreted as initial evidence for the IDCP-HPD, indicating the practicality of the test.
Resumo O objetivo deste estudo foi desenvolver uma versão do Inventário Dimensional Clínico da Personalidade 2 (IDCP-2) focada nos traços do transtorno da personalidade histriônico (TPH) de acordo com o modelo Hierarchical Taxonomy of Psychopathology (HiTOP), e verificar suas propriedades psicométricas. O método foi dividido em dois estágios. O primeiro para revisão do IDCP-2 de acordo com o HiTOP, focando nos traços típicos do TPH. O segundo objetivou verificar as propriedades da nova versão do IDCP-2 (i.e., IDCP-HPD) em uma amostra por conveniência (N=208), coletada via online. O IDCP-HPD foi aplicado junto a fatores do Personality Inventory for DSM-5 (PID-5) e Five-Factor Histrionic Inventory (FFHI). Dos 16 traços iniciais baseados no HiTOP, 8 foram selecionados para o TPH e 17 itens foram selecionados para os novos fatores. A solução com 4 fatores observada via exploratory structural equation modeling, as correlações com medidas externas e os efeitos das comparações entre grupos indicam a adequação psicométrica do IDCP-HPD. Os achados devem ser interpretados como evidências iniciais para o IDCP-HPD, indicando a praticidade do teste.
Resumen El objetivo de este estudio fue desarrollar una versión del Inventario Dimensional Clínico del Personalidad 2 (IDCP-2) que se centra en los rasgos del desorden histriónico de la personalidad (HPD) según el modelo de Taxonomía Jerárquica de la Psicopatología (HiTOP) y verificar sus propiedades psicométricas. El método se dividió en dos. Primero se relacionó con los procedimientos de revisión del IDCP-2 basados en el HiTOP, centrándose en la evaluación de las características típicas de HPD. El segundo verificou las propiedades psicométricas de la nueva versión del IDCP-2 (IDCP-HPD) en una muestra de conveniencia (N = 208), con la recopilación de datos en línea. El IDCP-HPD se administró con el Personality Inventory for DSM-5 (PID-5) y Five-Factor Histrionic Inventory (FFHI). De los 16 rasgos iniciales del HiTOP, 8 fueron seleccionados para el HPD y 17 ítens fueron seleccionados para componer los nuevos factores. La solución de 4 factores encontrada en modelo exploratorio de ecuaciones estructurales, las correlaciones y los efectos en las comparaciones entre grupos sugieren la adecuación psicométrica del IDCP-HPD. Los hallazgos de este estudio deben interpretarse como evidencia inicial para el IDCP-HPD, que indica la practicidad de la prueba.
ABSTRACT
Objective: To investigate the unique contribution of narcissism and impulsivity, in addition to callous-unemotional (CU) traits, in explaining concurrent prosocial and antisocial behavior. Method: Two hundred and forty-nine schoolchildren (53% female; age 9-12 years) completed the self-report Strengths and Difficulties Questionnaire (SDQ) and the Antisocial Process Screening Device (APSD). Two statistical models were tested, predicting conduct problems (CP) and prosocial behavior (PB). In the first one, CU traits and gender were entered into the equation. The second model added narcissism and impulsivity. Results: Gender, narcissism and impulsivity, but not CU, were statistically significant predictors of CP in the second model (F3,226 = 45.07, p < 0.001, R2 = 43.7%; betas: gender = -0.20, narcissism = 0.29, impulsivity = 0.36, CU = 0.06). PB was significantly predicted by all domains except gender (F3,226 = 42.57, p < 0.001, R2 = 42.4%; betas: gender = 0.08, narcissism = -0.16, impulsivity = -0.23, CU = -0.41). Conclusion: Our results confirmed that CU traits refer to a distinct manifestation of psychopathy in youth, but we also found that narcissism and impulsivity are equally important when predicting CP. Previous reports of sex differences on APSD and SDQ domains were also corroborated.

OBJECTIVES: The symptomatic and behavioral correlates of childhood trauma in schizophrenia are beginning to emerge in the literature. This study aimed to investigate whether the association between personality traits and schizophrenia with childhood abuse can be replicated in Koreans using the Multiphasic Minnesota Personality Inventory (MMPI). METHODS: Eighteen schizophrenias with childhood abuse and 24 schizophrenic comparisons without abuse history were recruited at the inpatient units of two general hospitals and the subjects completed the MMPI. RESULTS: Subjects with schizophrenia plus childhood history of abuse had less educational years (p<.001). After controlling the educational year as a covariate, abused schizophrenic patients had higher scores in the Schizotypal (p=.003), Dependent (p=.014), Passive-aggressive (p=.034), Borderline (p=.045) subscales. For the validity and clinical subscales, significant differences were found in the F scale (p=.036), Hypochondriasis (p=.042), Depression (p<.001), Hysteria (p=.002), Personality disorder (p=.001), Paranoia (p=.024), Psychasthenia (p=.001) and Schizophrenia (p=.006) subscales. CONCLUSION: Our findings suggest that childhood abuse in schizophrenia is associated with more complex features of personality characteristics rather than specific cluster B personality traits.

Objective: To study the defense style of undergraduates with cluster B personality disorders. Methods:26 undergraduates with cluster B personality disorders were diagnosed by PDQ~ +4 and PDI from 2826 undergraduates, then they and 63 normal undergraduates were assessed with DSQ (defensive style questionnaire). Results: ①The incidence of histrionic, narcissistic, borderline and antisocial personality disorders were 0.25%?0.50%?0.39% and 0.11% .②The undergraduates with B cluster personality disorder had higher scores in immature defenses and idealization, omnipotenic-devaluation and isolation than normal control (t=3.18-7.03)(P
ABSTRACT
Objective: To explore the symptomatology of cluster-B personality disorders from perspective of the Five-Factor Model (FFM).Methods:PDQ +4 was administered to college students and minor criminals to screen cluster-B subjects, Cluster-B patients were then diagnosed by conducting interview using PDI-IV.FFM of the subjects are measured with NEO-PI-R.Results:Cluster-B patients scored higher in Neuroticism(62.0?10.6), and lower in, Agreeableness(38.4?11.5) and Conscientiousness (38.4?11.2)than normal adult.Extraversion(45.9?11.5)and Openness to Experience(45.0?9.3)are near the lower limits.Bivariate analysis between PDI-Ⅳ and NEO-PI-R showed that APD negatively correlated with Agreeableness (r=-0.25,P
