ABSTRACT
Resumen Las principales herramientas de evaluación de la personalidad se construyeron a partir de las bases teóricas del modelo de los Cinco Factores. Particularmente, en Argentina, el IPIP-NEO es uno de los instrumentos, basados en este modelo, que presenta resultados satisfactorios en los estudios de consistencia interna (confiabilidad) y de validez mediante evidencia de estructura interna (análisis factorial exploratorio). El objetivo de este trabajo fue aportar nuevos estudios psicométricos a la escala utilizando una muestra heterogénea de argentinos (N = 499). Se estimó la estabilidad temporal de las puntuaciones a través del método test-retest y se realizó un estudio de validez de estructura interna mediante análisis factorial confirmatorio. Por otro lado, se aportó validez externa a través de estudios de convergencia, estudios de contraste de grupos divididos por sexo y edad, y un análisis test criterio mediante regresión múltiple con actividades recreativas. Los resultados sugieren que las puntuaciones que del IPIP-NEO son estables, con adecuados índices de confiabilidad y evidencias de validez externa, lo que indica que puede ser utilizado en muestras argentinas. Se planifica la elaboración de un baremo local y nuevos estudios de validez externa con implicancias clínicas y laborales.
Abstract The main personality assessment tools were built on the theoretical basis of the Five Factors model. Particularly, in Argentina, IPIP-NEO is one of the instruments, based on this model, that presents satisfactory results in the studies of internal consistency (reliability) and validity through evidence of internal structure (exploratory factor analysis). The aim of this work was to contribute new psychometric studies to the scale using a heterogeneous sample of Argentinean (N = 499). The temporal stability of the scores was estimated through the test-retest method and an internal structure validity study was performed by confirmatory factor analysis. On the other hand, external validity was provided through convergence studies, contrast studies of groups divided by sex and age, and a test criterion analysis through multiple regression with recreational activities. The results suggest that the IPIP-NEO scores are stable, with adequate reliability indices and evidence of external validity, indicating that it can be used in Argentine samples. The development of a local scale and new studies of external validity with clinical and labor implications are planned.
ABSTRACT
Antecedente: La conducta antisocial refiere al conjunto de actos que violan las normas establecidas para la convivencia de una sociedad. Entre las medidas de autoinforme para valorar esta conducta se encuentra la Escala de Desviación de la Norma (EDN). Objetivo: Considerando que en el contexto argentino no se encontraron estudios sobre las propiedades psicométricas de la escala, el objetivo de este estudio fue analizar sus propiedades psicométricas en una muestra de jóvenes argentinos. Método: Para este fin, se conformó una muestra de 794 participantes con edades comprendidas entre los 18 y 25 años. Se realizó un análisis factorial confirmatorio, se analizó el índice de confiabilidad compuesta y se estudió la validez convergente, discriminante y concurrente (utilizando una escala de autocontrol). Además, se analizó la invarianza del modelo de medida. Resultados: Entre los principales resultados se confirmó la estructura factorial original de la escala sin equivalencia factorial entre los grupos evaluados considerando el sexo, y se encontraron adecuadas propiedades psicométricas para la mayoría de las dimensiones que componen el instrumento. Discusión: Se discuten los hallazgos, limitaciones y futuras líneas de investigación.
Background: Antisocial behavior refers to a set of acts that violate the rules established for the coexistence of society. One of the self-report measures to assess this type of behavior is the normative deviance scale (NDS). Objective: Considering that in the Argentine context no studies on the psychometric properties of the scale were found, the present study aimed to analyze the psychometric properties of the scale in a sample of Argentine youths. Method: To this end, a sample of 794 participants aged between 18 and 25 years was collected. A confirmatory factor analysis was performed; the composite reliability was calculated; and the convergent, discriminant and concurrent validity was assessed (using a self-control scale). In addition, the invariance of the factorial structure of the scale was analyzed. Results: The results confirmed the original factorial structure of the scale with no factorial equivalence across the assessed groups regarding the sex. Also, the results showed adequate psychometric properties for most dimensions which make up the instrument. Conclusions: Findings, limitations and further lines of research are discussed.
ABSTRACT
PURPOSE: Few studies have been conducted on Latin American population to explore how facets of personality, eating disorders, and obesity are related. The main purpose of this study was to explore the personality traits among patients diagnosed with anorexia nervosa (n = 23), bulimia nervosa (n = 32), and obesity (n = 16), in comparison to control group (n = 82). METHODS: A total of 153 individuals participated in the study, 125 were female (81.7%) and 28 were male (18.3%). Participants' ages ranged between 18 and 37 years (mean 24.21, SD 4.84) and they were all native Spanish speakers, living in the city of Córdoba, Argentina. Participants completed the Eating Disorder Inventory-2 and the IPIP-NEO Personality Inventory. RESULTS: In this study, the subjects diagnosed with anorexia in comparison to control group showed high and significant scores in neuroticism and openness to experience and low scores on agreeableness, conscientiousness, and extraversion. For their part, the subjects diagnosed with bulimia, in comparison to the control group, had higher and significant scores on neuroticism, extraversion, and conscientiousness. Lastly, the patients with obesity in comparison to the control group presented high and significant scores on neuroticism and low and significant scores on agreeableness, extraversion, conscientiousness, and openness to experience. CONCLUSIONS: The results obtained from this study support previous research devoted to the study of eating disorders and obesity. This situation favors the valid and relevant nature of the study of personality traits as factors that contribute to explaining behavior disorders associated with eating pathologies. This is a preliminary and necessary step for future research to examine the risky combination of personality traits and anorexia, bulimia, and obesity in the local context using a larger and more generalized sample.
