Analysis of relationships between personality factors and the risk of Eating Disorders

Introduction: Regarding the origin of Eating Disorders, different psychological variables such as the personality, have been identified as risk factors for the onset and subsequent development of these pathologies. This study aimed to analyse the relationships between personality and different risk variables for the development of ED in the population of female students without disorders. Method: Participants included 627 women, Spanish university students, who completed the Eating Disorder Inventory-3 (EDI-3) and the Five-Factor Inventory (NEO-FFI). Correlation and regression analyses were conducted in order to observe patterns of common variation among the variables, and to determine the contribution of the personality traits in the explanation of the variables. Results: Neuroticism correlated significantly with all scales and is the main predictor of the risk scales (drive for thinness, bulimia and body dissatisfaction), and the seven psychological scales. The remaining factors showed negative correlations with all of the scales. Extraversion was the main predictor variable in the explained variance of interpersonal insecurity and interpersonal alienation. In addition, conscientiousness and agreeableness demonstrated an effect on different scales in combination with other factors. Conclusion: The study sustained the importance of personality in the risk of developing ED. Neuroticism is the factor that is most closely related to the risk variables and psychological constructs which are conceptually relevant in the development and maintenance of these disorders. The study of personality should help in identifying at-risk populations, and will enable adopting solutions aimed at the prevention of ED.

Introducción: En el origen de los trastornos alimentarios han sido identificadas diferentes variables psicológicas como factores de riesgo, como la personalidad, para el inicio y posterior desarrollo de estas patologías. El objetivo del estudio fue analizar las relaciones entre la personalidad y diferentes variables de riesgo para el desarrollo de trastornos alimentarios, en la población de mujeres universitarias sin trastornos. Método: Las participantes fueron 627 mujeres, estudiantes universitarias españolas, que completaron el Eating Disorder Inventory-3 (EDI-3) y el Five-Factor Inventory (NEO-FFI). Se realizaron análisis de correlación y regresión para observar los patrones de variación común entre las variables y para determinar la contribución de los rasgos de personalidad en la explicación de las variables. Resultados: El neuroticismo correlacionó significativamente con todas las escalas, y fue la principal variable predictiva en la varianza explicada de las escalas de riesgo (obsesión por la delgadez, bulimia e insatisfacción corporal), y siete escalas psicológicas. Los rasgos de personalidad restantes mostraron correlaciones negativas con todas las escalas. Extraversión fue la principal variable predictora de la varianza explicada de inseguridad interpersonal y alienación personal. Además, responsabilidad y amabilidad mostraron efecto en combinación con otros factores en diferentes variables. Conclusión: El estudio apoyó la importancia de la personalidad en el riesgo de desarrollar trastornos alimentarios. El neuroticismo es el factor que más se relaciona con las variables de riesgo y constructos psicológicos conceptualmente relevantes en el desarrollo y mantenimiento de estos trastornos. El estudio de la personalidad debería ayudar a identificar a las poblaciones de riesgo y adoptar soluciones dirigidas a la prevención.

Five-factor model of personality and Parkinson's Disease: a systematic review

Some studies have associated Parkinson's disease with specific personality traits. We aimed to analyze personality profiles in Parkinson's disease based on the Five- Factor Model, using the following 3 instruments as parameters: NEO Personality Inventory, revised NEO Personality Inventory, and NEO Five-Factor Inventory. A systematic review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses. The PsycINFO, PubMed, Scopus, and Web of Science databases were searched. The initial search resulted in 232 studies, and 11 studies were selected for full-text review. The personality traits most commonly associated with Parkinson's disease were high neuroticism and low extraversion and conscientiousness. These results cannot be attributed only to Parkinson's disease because other associated diseases were present in the included studies. Evidence from these studies is insufficient to state that there is a typical personality profile associated with Parkinson's disease, given that this profile is nonspecific and found in many psychopathological disorders that differ considerably from each other. This study was registered with PROSPERO (registration number CRD42021271526)

Alguns estudos têm associado a doença de Parkinson a traços de personalidade específicos. Esta pesquisa teve como objetivo analisar o perfil de personalidade na doença de Parkinson com base no Modelo dos Cinco Fatores, utilizando como parâmetro três instrumentos baseados nessa teoria: NEO Personality Inventory, NEO Personality Inventory revisado e NEO Five-Factor Inventory. Foi realizada uma revisão sistemática de acordo com os critérios de Preferred Reporting Items for Systematic Reviews and Meta-Analyses. Foram consultadas as bases de dados PsycINFO, PubMed, Scopus e Web of Science. A busca inicial resultou em 232 estudos, e 11 deles foram selecionados para análise completa. Os traços de personalidade mais frequentemente associados à doença de Parkinson foram o elevado neuroticismo e baixos níveis de extroversão e de conscienciosidade. Estes resultados não podem ser atribuídos apenas à doença de Parkinson, uma vez que outras doenças associadas estavam presentes nos trabalhos avaliados. Não há evidências suficientes nestes estudos para afirmar que existe um perfil de personalidade típico associado à doença de Parkinson, visto que esse perfil é inespecífico e encontrado em muitos transtornos psicopatológicos que diferem consideravelmente entre si. Este estudo foi registrado na plataforma International Prospective Register of Systematic Reviews ­ PROSPERO (número CRD4202127151526)

Changes in personality traits in patients with Alzheimer's Disease / Mudanças nos traços de personalidade em pacientes com doença de alzheimer

ABSTRACT. Changes in personality traits in patients with Alzheimer's disease (AD) are extremely common throughout the course of the pathology, and these behavioral changes present themselves as challenges in clinical management and as a significant cause of caregivers' burden. Objective: Using a personality inventory based on the five-factor model of personality, this study aimed to assesses the change in these factors by comparing the premorbid and current personality of individuals recently diagnosed with AD. Methods: A total of 30 AD patients were recruited, and their respective family members responded to the personality inventory at home through a hosted site. The patients were also divided into two groups according to the Clinical Dementia Rating (CDR): mild dementia (CDR 1) and moderate dementia (CDR 2). Results: Among all patients, there was a significant increase in neuroticism factor levels and a significant decrease in the extraversion, conscientiousness, openness, and socialization factors. When comparing the groups, only the extraversion factor showed a difference, with CDR 1 group accusing a higher change in scores. Higher scores in the factor neuroticism in the premorbid personality correlated with the current severity of the disease. Conclusions: This research draws the attention of family members and health professionals to changes in personality traits or behavior of relatives or patients, because it can reflect an underlying neurodegenerative process.

RESUMO. Mudanças em traços de personalidade em pacientes com doença de Alzheimer (DA) são extremamente comuns ao longo do curso da referida patologia, e essas alterações comportamentais apresentam-se como desafios no manejo clínico e como causa significativa de esgotamento dos cuidadores. Objetivo: Por meio de um inventário de personalidade baseado nos cinco fatores de personalidade, este estudo avalia a mudança nos escores desses fatores comparando a personalidade pré-mórbida e a atual dos indivíduos com DA. Métodos: O total de 30 pacientes com DA foi recrutado, e seus familiares responderam ao inventário de personalidade. Os pacientes também foram divididos em dois grupos conforme a avaliação clínica da demência: demência leve (CDR1) e demência moderada (CDR2). Resultados: Em todos os pacientes, houve aumento significativo nos escores do fator neuroticismo e decréscimos significativos nos fatores extroversão, realização, abertura e socialização. Quando feita a comparação entre grupos, apenas o fator extroversão apresentou diferença, com o grupo CDR 1 mostrando maiores mudanças nos escores. Os níveis do fator neuroticismo da personalidade pré-mórbida correlacionaram-se com a gravidade da doença no momento do diagnóstico. Conclusões: Este estudo procura esclarecer aos familiares e profissionais de saúde que mudanças em traços de personalidade de seus parentes ou pacientes podem refletir processos neurodegenerativos subjacentes.

Cuestionario Revisado de Personalidad de Eysenck (versión reducida): análisis con la teoría de respuesta al ítem / Revised Eysenck Personality Questionnaire (Brief Version): Analysis with Item Response Theory

Resumen El objetivo de este trabajo es aportar nuevas evidencias de calidad psicométrica para la adaptación argentina de la versión reducida del Cuestionario de Personalidad de Eysenck (EPQ-RS). Participaron 1136 personas de población general (52.5% femenino, edad media = 29.6 años, DE = 11.9) residentes en Buenos Aires, Argentina. La adaptación argentina se compone de 42 ítems con formato de respuesta dicotómica. Se realizó un análisis factorial confirmatorio a partir de la matriz de correlaciones tetracóricas. Esto permitió replicar la estructura propuesta por Eysenck para el modelo PEN (Psicoticismo-Extraversión-Neuroticismo) y la escala Sinceridad. Posteriormente, se ajustó el modelo logístico de dos parámetros por separado para los ítems de cada escala. Los ítems no mostraron funcionamiento diferencial según género. La discriminación de los ítems resultó moderada-alta. Los parámetros b se localizaron en rangos acotados de cada uno de los rasgos medidos, lo que originó que la precisión de las escalas varíe en el recorrido de los continuos. La escala Neuroticismo aporta más información en niveles medios del rasgo, Psicoticismo en los medio-bajos y Extraversión en los medio-altos. La escala Sinceridad mostró una función de información relativamente plana en todo el recorrido del rasgo. Se brindan evidencias de validez basadas en la relación con otras pruebas que miden facetas del neuroticismo y sintomatología. Las evidencias de validez y confiabilidad obtenidas ofrecen garantías de calidad suficientes para la aplicación de este instrumento en el contexto local y confirman la vigencia del modelo teórico que operacionaliza el EPQ-RS.

Abstract The aim of this work is to provide new evidence of psychometric quality for the Argentinean adaptation of the brief version of the Eysenck Personality Questionnaire (EPQ-RS). 1136 people from the general population (52.5% female, mean age = 29.6 years, SD = 11.9) residing in Buenos Aires, Argentina participated. The Argentinean adaptation consists of 42 items with dichotomous response format. A confirmatory factor analysis was performed from the tetrachoric correlation matrix. This allowed replicating the structure proposed by Eysenck for the PEN model (Psychoticism - Extroversion - Neuroticism) and the Lie scale. Subsequently, the two-parameter logistic model was adjusted separately for the items of each scale. The items did not show differential functioning by gender. Items discrimination was moderate-high. Parameters b were located in narrow ranges of each one of the measured traits, which caused the precision of the scales to vary along the trait continuums. The Neuroticism scale provides more information at medium levels of the trait, Psychoticism in the medium-low and Extraversion in the medium-high. The Lie scale showed a relatively flat information function throughout the trait. Evidence of validity based on the relationship with other tests that measure facets of neuroticism and symptomatology is provided. The evidence of validity and reliability obtained offers sufficient quality guarantees for the application of this instrument in the local context and confirms topicality of the theoretical model that operationalizes the EPQ-RS.

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

Abstract 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.

Risk Factors for Difficult Sedation-free Colonoscopy / 胃肠病学

Background: Colonoscopy has been widely applied in clinic because of its value in screening, diagnosis and treatment of colorectal diseases. Discomfort and pain account for a great part of incomplete intubation during sedation-free colonoscopy. Aims: To identify the predictive factors for difficult sedation-free colonoscopy. Methods: Patients aged 18-80 years old undergone sedation-free colonoscopy at the Tenth People's Hospital of Tongji University from January to December in 2017 were enrolled. The clinical data and medical history were collected. Each patient completed the Eysenck Personality Questionnaire (EPQ) with the help of nurse before colonoscopy. Sedation-free colonoscopy was performed by experienced endoscopist. The Ottawa bowel preparation scale and Visual Analog Scale were used to evaluate the quality of bowel cleansing and pain during the procedure. Results: The total cecum intubation rate was 97.1% (198/204), and 192 patients completing the EPQ were enrolled for analyses. Twenty-four patients had a difficult colonoscopy (intubation time prolonged to >10 min). By univariate analysis, gender, age, body mass index (BMI), history of surgery, pain level and score of Extraversion-Introversion Scale of EPQ (EPQ-E) were associated with difficulty during colonoscopy (all P<0.05). Multivariate analysis revealed that history of pelvic surgery was a risk factor for difficult colonoscopy (OR=6.833, 95% CI: 2.396-19.488, P<0.001), whereas overweight (OR=0.190, 95% CI: 0.038-0.962, P=0.045) and score of EPQ-E ranged from 8-15 (OR=0.367, 95% CI: 0.150-0.896, P=0.028) were protective factors. Conclusions: History of pelvic surgery, lower BMI and extraversion or introversion personality may increase the difficulty during sedation-free colonoscopy. EPQ-E might be used for selecting candidates of sedation-free colonoscopy when it is performed by an inexperienced endoscopist.

Relation of interpersonal adaptation to extraversion and self-control in college students / 中国心理卫生杂志

Objective: To explore the situation of interpersonal adaption and its relation to extroversion and self-control in college students. Methods: Totally 3125 college students (1497 males, 1628 females; age from 16 to24 years) were assessed with the interpersonal adaption dimension from China College Student Adjustment Scale (CCSAS), Neuroticism Extraversion Openness Five-Factor Inventory (NEO-FFI) and Self-Control Scale (SCS). Results: The average score of interpersonal adaption was (33. 3 ± 3. 6). Regression analysis showed that extraversion and self-control positively predicted interpersonal adaption (β = 0. 25, 0. 08), interaction of extraversion and selfcontrol negatively predicted interpersonal adaption significantly (β =-0. 08). In the introvert group, the interpersonal adaption scores were higher in students with higher self-control scores than in those with lower self-control scores (P ＜ 0. 001). Conclusion: It suggests that college students have good interpersonal adaptation. Self-control may buffer the negative effect of low extraversion on interpersonal adaption.

The analysis of pschological status of patients with oral lichen planus / 实用口腔医学杂志

Objective: To investigate the pschological status of the patients with oral lichen planus disease (OLP) . Methods: 100 patients with OLP and 100 healthy controls were included. The self-rating anxiety scale (SAS), self-rating depression scale (SDS), neuroticism extraversion openness (NEO) and WHOQOL-BREF were used to analyze the life quality and pschology of the subjects.Andrenocor-cicotropin (ACTH) and cortisol (CORT) in serum were measured. The relationship between OLP and mental illness, stress, personality traits and life quality was analyzed. Results: There were no significant differences of gender and age between the case group and the control group (P＞ 0. 05) . There were significant differences of the SAS score, SDS score, NEO score, WHOQOLBREF score and the level of ACTH and CORT (P ＜ 0. 05) in serum between the 2 groups. Logistic regression analysis showed that anxiety, depression, personality and life quality were the influencing factors of OLP prevalence. Conclusion: The development of OLP may be related to psychological status, depression, stress, anxiety and so on.

Statistical procedure of multipleregression and correlation was used.Results: Results displayed a positive correlation between neuroticism and loneliness for both age groups19 to 25 years and 40 to 50 years. However, there was a negative correlation between conscientiousnessand loneliness for age group 19 to 25 years; and negative correlation between extraversion and lonelinessfor age group 40 to 50 years.Conclusion: It can be concluded that there is a significant relationship between certain personality traitsand loneliness for specific age groups

Diferencias en temperamento según nivel socioeconómico en niños chilenos de 12 y 30 meses / Differences in temperament according to socioeconomic status in 12 to 30 months Chilean children

Resumen Se entiende el temperamento como el conjunto de diferencias individuales en reactividad y autorregulación, manteniéndose relativamente estable a través del tiempo, y siendo influenciado por la herencia, la maduración biológica y el contacto con el ambiente. En el presente estudio se buscó establecer si se dan diferencias en las dimensiones de temperamento de extraversión, afecto negativo y autorregulación según nivel socioeconómico, en niños chilenos asistentes a sala cuna. Se evaluaron 103 niños de ambos sexos, a los 12 y a los 30 meses de edad, con los cuestionarios IBQ-R-VSF y ECBQ-VSF, los cuales respondieron los padres. Los resultados mostraron que entre los 12 y 30 meses la extraversión se mantuvo constante, mientras que las dimensiones de afecto negativo y autorregulación disminuyeron de manera significativa. A los 12 meses los niños de NSE alto mostraron una mayor autorregulación, mientras que a los 30 meses los niños de NSE bajo evidenciaron un mayor afecto negativo. Se discuten los resultados en base a la evidencia encontrada sobre las diferentes realidades en los distintos niveles socioeconómicos.

Abstract Temperament is understood as the set of individual differences in reactivity and self-regulation, considered as stable through time, and influenced by the heritability, the biological maturation, and the interaction with the environment. The aim of this study was to determine if the dimensions of temperament (extraversion, negative affect, and self-regulation) show differences according to socioeconomic status in Chilean children attending to nurseries. For this study, 103 children from both genders were evaluated at 12 and 30 months old, using the IBQ-R-VSF and ECBQ-VSF questionnaires, which were answered by their parent. Results showed that between 12 and 30 months, extraversion remained constant, while the dimensions of negative affect and self-regulation decreased significantly. Children from high socioeconomic status showed higher self-regulation at age of 12 months, while the ones from low socioeconomic status decreased their negative affect at 30 months old. Results are discussed based on evidence about realities from different socioeconomic statuses.

Forensic Psychiatric Assessment for Organic Personality Disorders after Craniocerebral Trauma / 法医学杂志

OBJECTIVES@#To explore the occurrence and the differences of clinical manifestations of organic personality disorder with varying degrees of craniocerebral trauma.@*METHODS@#According to the International Classification of Diseases-10, 396 subjects with craniocerebral trauma caused by traffic accidents were diagnosed, and the degrees of craniocerebral trauma were graded. The personality characteristics of all patients were evaluated using the simplified Neuroticism Extraversion Openness Five-Factor Inventory （NEO-FFI）.@*RESULTS@#The occurrence rate of organic personality disorder was 34.6% while it was 34.9% and 49.5% in the patients with moderate and severe craniocerebral trauma, respectively, which significantly higher than that in the patients （18.7%） of mild craniocerebral trauma （P<0.05）. Compared with the patients without personality disorder, the neuroticism, extraversion and agreeableness scores all showed significantly differences （P<0.05） in the patients of mild craniocerebral trauma with personality disorder; the neuroticism, extraversion, agreeableness and conscientiousness scores showed significantly differences （ P>0.05） in the patients of moderate and severe craniocerebral trauma with personality disorder. The agreeableness and conscientiousness scores in the patients of moderate and severe craniocerebral trauma with personality disorder were significantly lower than that of mild craniocerebral trauma, and the patients of severe craniocerebral trauma had a lower score in extraversion than in the patients of mild craniocerebral trauma.@*CONCLUSIONS@#The severity of craniocerebral trauma is closely related to the incidence of organic personality disorder, and it also affects the clinical features of the latter, which provides a certain significance and help for forensic psychiatric assessment.

Personal characteristics of paradoxical insomnia: A case-control study / 中南大学学报(医学版)

Objective:To compare the personal characteristics between the patients with paradoxical insomnia and the patients with primary insomnia or the normal sleepers.Methods:A case-control study with the proportion at 1∶1∶1 was carried out.The patients with paradoxical insomnia were diagnosed in Sleep Medicine Center of West China Hospital of Sichuan University between March 2013 and December 2013.A case of paradoxical insomnia was matched with two controls:a primary insomnia patient and a normal sleeper.A total of 63 matched cases were collected.A face-to-face survey was conducted by using the following scales:General Data Scale and Eysenck Personality Questionnaire (EPQ).Results:The average scores of psychoticism,extraversion,and neuroticism for paradoxical insomnia cases were (52.1±10.2),(49.6±9.8),and (56.0±12.0),respectively.In general,31.7% of paradoxical insomnia patients had psychoticism or psychoticism tendency in their personality,which were more obvious than those in primary insomnia patients (7.9%) (x2=l 1.228,p0.0125).Conclusion:The personal characteristics for paradoxical insomnia patients did not reached obviously abnormal level.However,their psychoticism tendency,extroversion tendency and neuroticism tendency needed to be paid attention.

How Much We Think of Ourselves and How Little We Think of Others: An Investigation of the Neuronal Signature of Self-Consciousness between Different Personality Traits through an Event-Related Potential Study

Background: Previous studies have revealed that self-related tasks (items) receive more attention than non-self-related, and that they elicit event-related potential (ERP) components with larger amplitudes. Since personality has been reported as one of the biological correlates influencing these components, as well as our behavioural differences, it is important to examine how it affects our self-consciousness in relation to tasks of varied relevance and the neurological basis. Methods: A total of 33 male and female undergraduate Malaysian medical students of Universiti Sains Malaysia (USM) participated in the study. The participants were divided into two groups, Ambivert (n = 18) and Extravert (n = 15) groups, using the USM personality inventory questionnaire. In the ERP experiment, squares containing standard stimuli of any word other than self and non-self-related nouns (e.g., Bola, Gigi, Anak, etc.; in English: Ball, Teeth, Kids, etc., respectively), those containing self-related pronouns (Saya, Kami or Kita; in English: I, Us or We, respectively), and non-self-related pronouns (Dia, Anda or Mereka; in English: He/She, You or They, respectively), were shown 58%, 21% and 21% of the time, respectively, in a three-stimulus visual oddball paradigm. All words were presented in Bahasa Melayu. The participants were instructed to press 1 for self and 2 for non-self, and ignore standard stimuli. Results: Comparison of both N200 and P300 amplitudes for self-related and non-selfrelated pronouns in the Extravert group revealed significant differences at seven electrode sites, with self-related having larger amplitude at anterior electrodes and less at posterior. This was not seen in the Ambivert group. Conclusion: The present study suggests that self-relevant pronouns are psychologically more important to extraverts than to ambiverts; hence, they have more self-awareness. This may be due to large amount of dopamine in the brains of extraverts, which is more concentrated in the frontal lobe.

A psicopatia no contexto dos cinco grandes fatores da personalidade / Psychopathy in the context of the big five personality factors / Psicopatía en el contexto de los cinco grandes factores de personalidad

A psicopatia configura-se como um grave transtorno da personalidade. Apesar de resultados indicarem a extroversão e amabilidade como dois dos marcadores dos big five como seus preditores, são escassas as evidências no Brasil. Portanto, este estudo objetivou conhecer em que medida os fatores de personalidade normal se correlacionam com os três fenótipos avaliados pela Medida Triádica de Psicopatia (TriPM). Participaram da pesquisa 228 estudantes universitários de João Pessoa (PB), apresentando idade média de 25,1 anos, a maioria do sexo feminino (76%). Estes responderam a TriPM, o Inventário dos Cinco Grandes Fatores da Personalidade e perguntas demográficas. Os resultados indicaram que os fatores extroversão, abertura à mudança e amabilidade predisseram a psicopatia, corroborando estudos prévios. Estes achados são discutidos tomando como base o modelo dos big five para compreender este traço socialmente desviante, onde a ausência de afeto e o comportamento manipulador são características centrais.

Psychopathy is a severe personality disorder. Despite results indicating that extraversion and agreeableness are two markers of the big five as its predictors, evidence in Brazil are limited. Therefore, this study aimed to know whether normal personality (non-psychotic) factors predict the three phenotypes evaluated by the Triarchic Psychopathy Measure (TriPM). Participants were 228 undergraduate students from João Pessoa (PB), with mean age of 25.1 years, mostly were female (76%). They answered the TriPM, the Big Five Inventory, and demographic questions. Results indicated that the factors extraversion, openness to experience and agreeableness predicted psychopathy, which corroborated previous studies. These findings are discussed on the basis of the big five model in order to understand this socially deviant trait, in which the lack of affection and the manipulative behavior are central features.

La psicopatía se configura como un transtorno grave de la personalidad. Aunque los estudios indican extraversión y amabilidad como dos de los cinco marcadores como sus predictores, se ha observado poca evidencia en Brasil. Por lo tanto, este estudio tuvo como objetivo conocer en qué medida los factores de la personalidad normal se correlacionan con fenotipos contemplados por la Medida Triádica de Psicopatía (TriPM). Los participantes han sido 228 universitarios de João Pessoa (PB), con una edad promedia de 25.1 años, en mayoría mujeres (76%). Éstos contestaron la TriPM, Inventario de los Cinco Grandes Factores de Personalidad y preguntas demográficas. Los resultados indicaron que los factores extraversión, apertura a la experiencia y amabilidad se asociaron con la psicopatía, corroborando estudios previos. Se discuten estos hallazgos según el modelo de los cinco grandes, poniendo énfasis en ese rasgo socialmente desviante, caracterizado por la falta de afecto y la conducta manipuladora.

Influencia del tempo de la música en las emociones / Influence of music tempo on emotion

Se sabe que la música puede influir en dos componentes de las emociones: el arousal y la valencia. En particular, se ha reportado que el tempo o rapidez de la música está directamente relacionado con el arousal, aunque su relación con la valencia o medida de afecto no es aún clara. En este trabajo se analizó la influencia del tempo en ambos componentes mediante la exposición de 24 estudiantes de licenciatura a treinta extractos musicales de distinto tempo. Además se evaluó la posible modulación de la relación tempo-valencia por el rasgo de personalidad extroversión/introversión. Los resultados confirmaron la influencia del tempo sobre el arousal, pero no sobre la valencia, así como una posible mediación de la dimensión de personalidad introversión-extroversión sobre la valencia.

Arousal and valence, two main components of emotion, are known to be influenced by music. Particularly, some studies have shown a positive relationship between tempo (music speed) and arousal, but no conclusive evidence about tempo and valence relationship has been found. In this experiment, the effect of tempo on both arousal and valence was studied.Twenty four undergraduate students were exposed to 30 musical excerpts with different tempo. In addition, the possible mediation of the extraversion-introversion personality trait on the relationship tempo-valence was also determined. The results confirmed the effect of tempo on arousal but not on valence, and a mediating effect of introversion-extraversion personality dimension on valence.

College Students' Dietary and Health Behaviors related to Their Myers-Briggs Type Indicator Personality Preferences / 대한지역사회영양학회지

The objective of this study was to evaluate college students' dietary and health behaviors in relation to their Myers-Briggs Type Indicator (MBTI) personality preferences. Dietary and health behaviors were surveyed for 444 college students who performed the MBTI personality test. Only 6.1% of the subjects regularly had three meals a day, while 27.1% ate breakfast every day. Fifty-six point nine percent of the students took less than 15 minutes to eat a meal and had the habit of eating fast. The number of food groups they ate was, on average, 2.74 and was eaten mainly at dinner. This showed that college students did not eat a large variety of foods. Eighty-two percent of the subjects drank alcoholic beverages, 21.4% smoked, and 69.3% exercised. In addition, 73.9% of them were not satisfied with their body image, but they were not eager to try weight control. There were not many significant differences between Extraversion (E)-Introversion (I), Sensing (S)-iNtuition (N), and Thinking (T)-Feeling (F) in their dietary and heath behaviors, although some gender differences existed. Significantly better dietary and health behaviors were shown in subjects preferring Judging (J) rather than Perceiving (P). There behaviors included eating breakfast, regularly eating three meals a day, smoking less, exercising more and having a lower tendency to night-eating. The personality preference of J-P could be useful index for nutritional education and counseling or behavior modification programs for obese people.
