The Aggression Questionnaire (Buss & Perry, 1992) is one of the most used instruments to assess aggression; it includes 29 items grouped into 4 factors. Furthermore, a reduced version of 12-item has been proposed (Bryant & Smith, 2001), and it has also been examined by several researchers. Nevertheless, Latin-American samples have rarely been included. In this study, exploratory and confirmatory models were evaluated among a sample of adolescents from Cordoba, Argentina (N = 371). Moreover, internal consistency and gender invariance were examined. A 2-factor structure resulted in the exploratory analysis, while 2- and 4-factor (short and long versions) structures showed acceptable fits in confirmatory analysis. In general, internal consistency was acceptable, and gender invariance was supported. Implications and limitations are discussed.
A new measure of positive and negative alcohol expectancies for children aged 8 to 12 years was developed and validated. Study 1: 117 children answered a structured open-format question to provide information regarding the effects of alcohol use that they anticipate. The pool of items obtained was analyzed by a group of three experts according to the following criteria: item correspondence with two different theoretical models and item semantic clarity. Following analysis of the agreement between judges, a set of 55 items was obtained. Study 2: 209 children answered the Alcohol Expectancy Questionnaire for Children (CEA-N). Internal structure was analyzed through the use of exploratory factor analysis. A principal components analysis with oblimin rotation yielded a five-factor structure. The measure was found to demonstrate good internal consistency for the global and "risk and aggression" scales, and moderate internal consistency for the remaining four scales: sociability, relaxation, courage and negative mood. These results indicate that the CEA-N is a valid and reliable measure for assessing alcohol expectancies in Argentinean children.
El objetivo de esta investigación fue evaluar las diferencias en función de la edad, el género y el nivel socio-económico en el comportamiento social (habilidades sociales y problemas de conducta), la atención focalizada, el control inhibitorio, la emocionalidad (positiva y negativa) y la regulación emocional (positiva y negativa) en niños argentinos de tres, cinco y siete años de edad. Se realizó un estudio evolutivo transversal en el cual participaron los padres y docentes de 623 niños. Los padres brindaron información acerca de aspectos socio-demográficos, y sobre el temperamento y procesos emocionales de los niños, mientras que los docentes lo hicieron con respecto al comportamiento social de los niños. El estudio de las comparaciones entre grupos se efectuó a través de análisis de varianza. Las diferencias más marcadas se atribuyeron, en primer lugar, a la edad de los niños, y en segundo lugar, al género. En términos generales, los niños de tres años mostraron un menor desempeño que el resto de los grupos, pero el desarrollo no fue lineal en todos los procesos ya que los niños de cinco años presentaron un desempeño semejante o mejor en comparación con los niños de siete años, según algunas variables.
