Inventario IPIP-NEO: Estabilidad y Validez de Estructura Interna, Convergente y Concurrente en Muestras Argentinas

Abstract

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 traves 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.

The Influence of Gender and Age on the Open-Mindedness of University Students

“…By age, OM scores are highest in the youngest group in our study (<49 years), in line with the findings of authors such as [49,50,55], and decrease significantly with increasing age [81][82][83][84], until a critical point of decline at the age of 51-61 years, in which more cognitive than emotional traits may predominate [85], and interest in the new decreases, the mind becomes more conservative and seeks more security, to increase later, between 62 and 70 years of age, a stage in which the mind becomes more curious again, open to experience and new intellectual challenges, curious and flexible. This should be taken into account in the development of a university education that considers the peculiarities derived from age, making the most of the potential of the younger generations in Openness, motivating older and more conservative students towards more OM, and highlighting the potential of the older students in Intellect, based on their greater life experience, and as a complement to the lesser life experience of the younger students.…”

“…Authors such as [47,62] found significant differences in favour of older students (>25 years) compared to younger ones (<25 years), with a small effect size (d = 0.255). In some facets of OM, such as ideas and values, those over 50 years old obtained the highest scores [55]. In contrast, studies with large populations and different cultures have concluded that OM occurs mainly in younger people [50,55], with a small effect size (d of 0.443 and 0.23, respectively).…”

Longitudinal research showed decreasing openness to experience with age [49].…”

“…Other authors, such as Caballo et al [53], obtained slightly higher mean scores in females, but the differences were not significant. However, authors such as [54][55][56] found significant differences in favour of the male gender, with a small effect size (with Cohen's d between 0.22 and 0.477). Finally, other authors, such as Alvear [37,43,49,[57][58][59][60][61], found slightly higher mean scores in males, but the differences were not significant.…”

Influence of Training and Personality Traits on Entrepreneurial Intention and Behaviour

“…The variables measured were: Extraversion (4 items), Neuroticism (5 items), Agreeableness (4 items), Conscientiousness (6 items) and Openness to experience (4 items). The instrument was also used in other personality research [39], [40].…”
