Estructura factorial de la versión reducida del 'Eysenck Personality Profiler'

El objetivo de este trabajo es analizar la estructura factorial de la versión reducida del Eysenck Personality Profiler (EPP-SF), un cuestionario recientemente elaborado por Eysenck, Wilson y Jackson (1996) que permite la evaluación de los rasgos primarios más importantes que constituyen cada una de las tres dimensiones básicas de personalidad. Los resultados derivados de la aplicación de la técnica de análisis factorial y escalamiento multidimensional a las puntuaciones del EPP-SF de una muestra española de 946 sujetos replican los datos obtenidos en la muestra inglesa. La estructura factorial de la escala perfila claramente una composición tripartita y evidencia un aceptable grado de homogeneidad entre los rasgos primarios que constituyen cada uno de los tres tipos básicos de personalidad. Si bien, el rasgo primario de impulsividad sigue presentado saturaciones importantes en más de una dimensión. Este resultado es interpretado en los términos aducidos por el propio Eysenck, y otros autores, sobre la naturaleza multifactorial de este atributo de personalidad. Hecho que viene a constatar la necesidad de realizar estudios centrados en el análisis de la supuesta unidimensionalidad de las escalas que constituyen el EPP-SF.

Psychometric properties of the French version of the Zuckerman-Kuhlman Personality Questionnaire

Este estudio instrumental fue diseñado para investigar las propiedades psicométricas de la versión francesa y replicabilidad transcultural del Zuckerman-Kuhlman Personality Questionnaire (ZKPQ) en sus factores y facetas. El ZKPQ es un instrumento destinado a evaluar los cinco factores básicos del Alternative Five-Factor Model (AFFM). Los participantes fueron 843 suizos francófonos, principalmente estudiantes universitarios. Obtenidos los factores estos mostraron una fiabilidad entre 0,73 y 0,87, y sus facetas entre 0,57 y 0,77. Las diferencias entre géneros son similares a las informadas en la muestra americana. Las mujeres alcanzaron puntuaciones superiores en N-Anx, y puntuaciones más bajas en ImpSS y Act. El resultado de los análisis factoriales exploratorios respaldó la estructura de cinco factores y sus correspondientes facetas. Las correlaciones entre las escalas sostienen que los cinco factores básicos del AFFM son ortogonales. Los coeficientes de congruencia muestran la elevada eplicabilidad transcultural de los factores y sus facetas. Se puso a prueba el ajuste del modelo en sus factores y facetas mediante análisis factorial confirmatorio. Los resultados indican que la versión en lengua francesa del ZKPQ es un instrumento fiable y válido y posee buena replicabilidad transcultural.

The five and seven factors personality models: differences and similitude between the TCI-R, NEO-FFI-R and ZKPQ-50-CC

The present study tests the relationships between the three frequently used personality models evaluated by the Temperament Character Inventory-Revised (TCI-R), Neuroticism Extraversion Openness Five Factor Inventory – Revised (NEO-FFI-R) and Zuckerman-Kuhlman Personality Questionnaire-50- Cross-Cultural (ZKPQ-50-CC). The results were obtained with a sample of 928 volunteer subjects from the general population aged between 17 and 28 years old. Frequency distributions and alpha reliabilities with the three instruments were acceptable. Correlational and factorial analyses showed that several scales in the three instruments share an appreciable amount of common variance. Five factors emerged from principal components analysis. The first factor was integrated by A (Agreeableness), Co (Cooperativeness) and Agg-Host (Aggressiveness-Hostility), with secondary loadings in C (Conscientiousness) and SD (Self-directiveness) from other factors. The second factor was composed by N (Neuroticism), N-Anx (Neuroticism-Anxiety), HA (Harm Avoidance) and SD (Self-directiveness). The third factor was integrated by Sy (Sociability), E (Extraversion), RD (Reward Dependence), ImpSS (Impulsive Sensation Seeking) and NS (novelty Seeking). The fourth factor was integrated by Ps (Persistence), Act (Activity), and C, whereas the fifth and last factor was composed by O (Openness) and ST (Self- Transcendence). Confirmatory factor analyses indicate that the scales in each model are highly interrelated and define the specified latent dimension well. Similarities and differences between these three instruments are further discussed.

I want you! An experiment studying the selection effect when assigning distributive power.

We study whether selection affects motivation. In our experiment subjects first answer a personality questionnaire. They then play a 3-person game. One of the three players decides between an outside option assigning him a positive amount, but leaving the two others empty-handed and allowing one of the other two players to distribute a pie. Treatments differ in the procedure by which distributive power is assigned: to a randomly determined or to a knowingly selected partner. Before making her decision the selecting player could consult the personality questionnaire of the other two players. Results show that knowingly selected players keep less for themselves than randomly selected ones and reward the selecting player more generously.

Análisis de los componentes principales del rasgo "impulsividad" y de su relación con las

La multidimensionalidad de la escala “Impulsividad” ha sido y es un tema controvertido en el modelo teórico de Eysenck (Fusté y Ruiz, 2000a). Si bien, Eysenck y Eysenck (1977) defienden una estructura multicomponencial de la escala, el tratamiento que recibe en la versión reducida del Eysenck Personality Profiler (EPP-SF) (Eysenck, Wilson, y Jackson, 1996) no presenta la mencionada subdivisión en factores. Estudios precedentes sobre la estructura factorial de la escala ponen de manifiesto una composición tetrafactorial semejante a la propuesta por Eysenck y Eysenck (1977) (Fusté y Ruiz, 2000b), a la vez que demuestran saturaciones importantes de la escala en más de una dimensión (Fusté y Ruiz, 2000a). Es por todo ello que el objetivo de este estudio es analizar si los cuatro componentes que aparecen, pertenecen al dominio del Psicoticismo o por el contrario están más cerca de la Extraversión. Para ello se han analizado las puntuaciones obtenidas por una muestra de 1056 sujetos en cada uno de los cuatro componentes factoriales de la escala impulsividad obtenidos mediante un análisis de componentes principales de los ítems que componen dicha escala.

Adaptación española del cuestionario E.P.I. de Eysenck

A partir de la evolución de la estructura del gasto alimentario en los hogares españoles a lo largo de los últimos cuarenta, el artículo analiza la relación entre los cambios sociales, económicos, tecnológicos, demogrdficos, ideológicos, sanitarios, de estética corporal, etc. y los cambios habidos en 10s comportamientos alimentarios. Estos cambios permiten caracterizar una ccmodemidad alimentarias cuyos contenidos referirían a una articulación dinámica y compleja entre una revalorizacibn de las tradiciones culinarias y una udlización cada vez más frecuente de los productos elaborados por las industrias alimentarias.

¿Qué Calidad de Vida tienen nuestros asmáticos? Aplicación de la Versión Española Reducida del “Asthma Quality of Life Questionnaire” (AQLQ) o mini-AQLQ.

Estudio descriptivo transversal llevado a cabo en un centro urbano de atención primaria, con una muestra de 250 asmáticos, de entre 536 registrados en el centro, que pretende estudiar su calidad de vida y su relación con diferentes variables (edad, sexo, tabaquismo, patologías crónicas más prevalentes, ansiedad y/o depresión, rinitis alérgica, tipo de asma y grado de control). Para ello se les aplicó el test Mini-AQLQ, que valora la calidad de vida en una escala del 1 al 7 (15 preguntas), donde 1 supone el mayor grado de discapacidad y 7 el mayor grado de autonomía.

Subset correspondence analysis: Visualizing relationships among a selected set of response categories from a questionnaire survey

It is shown how correspondence analysis may be applied to a subset of response categories from a questionnaire survey, for example the subset of undecided responses or the subset of responses for a particular category. The idea is to maintain the original relative frequencies of the categories and not re-express them relative to totals within the subset, as would normally be done in a regular correspondence analysis of the subset. Furthermore, the masses and chi-square metric assigned to the data subset are the same as those in the correspondence analysis of the whole data set. This variant of the method, called Subset Correspondence Analysis, is illustrated on data from the ISSP survey on Family and Changing Gender Roles.

Revised NEO personality inventory normative data for catalan police officer selection: preliminary study

El Servei d'Avaluació, Seguiment i Selecció de l'ISPC han elaborat un estudi sobre el perfil de personalitat dels aspirants al Curs de Formació bàsica per policies, que es va presentar a l'International Society for the Study of Individual Differences Meeting celebrat al CosmoCaixa de Barcelona i que organitzen conjuntament l’Associació Iberoamericana per a la recerca de les diferències individuals i la Universitat de Barcelona. L’estudi, titulat Revised NEO Personality Inventory Normative Data for Catalan police officer selection: A preliminary study, té com a objectiu comparar els perfils de personalitat d’una mostra d’aspirants de l’ISPC amb els resultats d’una mostra d’aspirants a policia dels EUA, publicada en una revista científica de prestigi el mes de febrer passat. Els resultats mostren que els aspirants catalans destaquen per obtenir millors puntuacions en les dimensions de responsabilitat i amabilitat, cosa que indicaria que aquest tret es valora especialment durant el procés de selecció de la policia de Catalunya; en altres característiques de la personalitat les dues mostres obtenen resultats similars. Els trets característics del perfil del policia català seria el de persones estables emocionalment, poc impulsives, amb capacitat per gestionar l’estrés, orientades a les persones, agradables, sociables, responsables, disciplinades i cauteloses.

Resiliencia y persistencia académica en estudiantes inmigrantes

This article presents some of the results of a research project whose main objective was to analyse the relationship between resilience and school success of students of foreign origin at a time of special academic vulnerability: the transition from compulsory secondary education (ESO) to post-compulsory education (PO). By non-probabilistic-incidental sampling, the study was conducted in four schools of Barcelona and province, with 94 participants from 15 to 18 years old. This research of a longitudinal design had five phases combining strategies to collect qualitative and quantitative data. The results presented here are the result of the SV-RES adapted scale and two other self-produced toolsa center scale and a general questionnaire. The results obtained have confirmed the fulfilment of the hypothesis: immigrant students who manage to persevere in post-compulsory stages (Spanish Baccalaureate and/or Vocational Training) show higher levels of resilience.

Estudio del factor de personalidad Extroversión_Introversión mediante la técnica de los tiempos de reacción

A partir de una breve revisión bibliográfica de las caracteristicas y aplicaciones de la técnica de los tiempos de reacción, se ha planteado una experiencia en la que, siguiendo la linea de Eysenck, se aplica dicha técnica al estudio de la personalidad, concretada aquí en el factor introversión-extroversión. La hipótesis, confirmada en parte por los resultados obtenidos, planteaba en forma afirmativa la existencia de diferencias significativas entre el rendimiento y comportamiento de un grupo de introvertidos, ambivertidos y extrovertidos en unas pruebas de reacciometria.

The burnout syndrome and associated personality disturbances. The study in three graduate programs in Dentistry at the University of Barcelona

Objective: Determine the presence of"burnout" syndrome and characteristic personality patterns in the students and faculty of three graduate programs in Dentistry at the University of Barcelona: Department of Oral Surgery and Implantology, Department of Orthodontics and Department of Integrated Dentistry. Materials and Methods: The study was carried out in 78 dentists. The level of"burnout" was evaluated using the Maslach Burnout Inventory, socio-demographic variables and, finally, the personality test. Results: Oral surgeons constituted the group of highlevel"burnout". The profile of an individual with a propensity to"burn out" is a single man, with a median age of 27, that is in the first years of the graduate program and that combines studies with 30 hours of clinical practice and/or other work (p<0,05). Narcissistic and borderline are the types of personality most frequently found in the individuals that present"burnout" syndrome (p<0,05). Conclusions: In general, no high levels of"burnout" were registered in the studied population, only 2-3%, if applying strict definition of"burnout", and 10% if these criteria were amplified. We believe it is necessary to identify the individuals with a tendency towards"burnout", in order to establish preventive measures and avoid future negative behaviour at work as well as at the personal level.

Translation and validation of the Ten-Item-Personality Inventory into spanish and catalan

In response to an increasing need for ever-shorter personality instruments, Gosling, Rentfrow, and Swann (2003) developed the Ten-Item-Personality Inventory (TIPI), which measures the dimensions of the Five Factor Model (FFM) using 10 items (two for each dimension) and can be administered in about one minute. In two studies and using a multi-judge (self and observer) and multi-instrument design, we develop Spanish (Castilian) and Catalan versions of the TIPI and evaluate them in terms of internal consistency, test-retest reliability, convergent, discriminant, and content validity, as well as self-observer correlations. Test-retest correlations were strong, and convergence with the NEO-PI-R factors was significant. There were also strong correlations between observer ratings and the participants’ self-ratings. Despite some inconsistencies with respect to the Agreeableness scale, the Catalan translation and both translations into Spanish of the original TIPI demonstrated sufficient psychometric properties to warrant use as a Five Factor personality measure when the use of longer instruments is not convenient or possible. Furthermore, as the first translation of a brief standard Big Five Instrument into Catalan, this work should facilitate future research on personality in the Catalan-speaking population.

Implicación de la ansiedad y la depresión en los trastronos de alimentación de jovenes con obesidad

Objectives: the goals of the present study were: 1) to compare the levels of anxiety, depression, and eating disorders in young patients assisted at a children"s hospital for obesity; 2) to determine whether anxiety and depression explain the symptoms of the eating disorders; and 3) to know which of these symptoms better discriminate the young people with different degrees of obesity. Materials and method: Descriptive, cross-sectional study with a sample comprised by 281 youngsters (56% girls) aged 11-17 years. The BMI percentiles were calculated by using the WHO growth tables. Two study groups were created: severe obesity and overweight/light-moderate obesity. The following questionnaires were used: Eating Disorders Inventory-2 (EDI-2), depression questionnaire (DQ), and Status-Trait Anxiety Questionnaire (STAI). Results: The youngsters with obesity showed more psychological problems than youngsters with overweight/ light-moderate obesity, 12% had anxiety, and 11% depression. In both groups, the behaviours related with eating disorders were partially explained by the presence of symptoms of anxiety and depression. Dissatisfaction with the body and high anxiety trait increased the risk for perpetuating the obesity and were the two symptoms that better discriminated the patients with or without severe obesity. Conclusion: Obesity prevention programmes should include body dissatisfaction and the anxiety trait into the assessment and management protocols, and prevent anxiety getting fixed as a personality trait.
