La muestra total fue de 1703 participantes; 878 mujeres y 825 hombres, con una edad media de 20.5 años y 20.9 años, respectivamente. Los análisis factoriales confirmatorios mostraron que una estructura tetrafactorial (miedo a las personas mayores, apariencia física, miedo a las pérdidas, y preocupaciones psicológicas) es viable y adecuada para ambas poblaciones (mujeres y hombres) de acuerdo a los requisitos psicométricos establecidos cuando los informantes son los propios alumnos. Además, la estructura factorial, las cargas factoriales y los interceptos se consideran invariantes en las dos poblaciones. Sin embargo, existen diferencias entre las poblaciones para las medias de los factores miedo a las personas mayores y miedo a las pérdidas.

The overall sample consisted of 1703 participants: 878 women and 825 men, with a mean age of 20.5 years old and 20.9 years old, respectively. Psychometric analysis showed that a tetrafactorial structure (fear of old people, physical appearance, fear of losses, and psychological concerns) is feasible and adequate for both populations (women and men) according to the established psychometric requirements when the informers are the students themselves. In addition, factor structure, factor loadings and intercepts of the instrument could be considered invariant across groups. However, there are differences between groups for the means of the factors fear of old people and fear of losses.

Anxiety is a feeling of fear, dread or restlessness and can develop into a weight-related disorder. The objective was to analyze the psychometric properties of the trait anxiety subscale of the Physical Appearance State and Trait Anxiety Scale (PASTAS), as well as the invariance in Mexican preadolescents. The sample consisted of 604 participants, 285 female and 319 male, whose ages ranged between 11 and 12 years (M = 11.37; SD = 0.48). The questionnaire’s factor structure was analyzed using confirmatory factor analyses. The analyses show the viability and adequacy of a two-factor structure (weight and non-weight factors) both for the total sample and for the populations of male and female. The two-factor structure showed adequate reliability and validity fit indicators. The factor structure, the factor loadings and intercepts are considered invariant according to the variable sex; however, differences between female and male participants were found for levels of anxiety caused by physical appearance. In conclusion, the PASTAS can be considered a convenient instrument to assess the variables related to anxiety generated by one’s physical appearance, as well as allowing more participants to be quickly assessed.

Anxiety about aging is an important mediating factor in attitudes and behavior toward elderly individuals as well as a mediating factor in the adjustment to one’s own aging processes. The aim of this study was to analyze the factor structure, internal consistency and factorial invariance by sex of the Lasher and Faulkender Anxiety about Aging Scale. The sample consisted of 601 Mexican older adults, 394 women and 207 men, with a mean age of 70.69 ± 8.10 years. The factor structure of the questionnaire was analyzed using confirmatory factor analysis. Analyses show that a four-factor structure is feasible and adequate. The four-factor structure (fear of the elderly, psychological concerns, physical appearance and fear of loss), according to statistical and substantive criteria, showed adequate reliability and validity indicators. However, the obtained model does not fully coincide with that proposed by the questionnaire authors, although it continues to support the multi-factor component of anxiety about aging. On the other hand, the factor structure, the factor loadings and the intercepts are considered invariant in the two populations (men and women); however, there are differences between populations on the means of the physical appearance and fear of loss factors.

En este estudio se comparan los perfiles de estilos atributivos en el área de logros académicos en universitarios mexicanos. La muestra total fue de 1285 participantes; 660 mujeres y 625 hombres, con una edad media de 20.51 y 20.83 años respectivamente. La investigación fue de enfoque cuantitativa, descriptiva, tipo encuesta. Los participantes contestaron la versión informatizada del Cuestionario de Estilos Atributivos en el área de logros académicos adaptado previamente por los autores el año 2016. Los análisis de varianza multivariante y univariados, muestran que las mujeres en comparación con los hombres reportan mayores niveles de control interno en las dimensiones atribución a la suerte, atribución a la habilidad, atribución al profesor y sin diferencias en atribución al esfuerzo. Se concluye que dichas diferencias sugieren que al diseñar cualquier intervención para promover el cambio en los estudiantes hacia un estilo de control más interno habrá que tomar en cuenta al género.

Child abuse is not only a serious violation of children's rights and well-being, but also the worst example of how to relate and bond with others. Violence against an intimate partner during adulthood may have as background the emotional experiences and early learning associated with parents as the most significant developmental figures. The study of men who have been convicted of crimes of domestic violence against women may shed light on how childhood experiences impact aggressive adult behavior. Accordingly, this research explores the relationships between attachment style, childhood parental abuse experiences and aggression in adult life in a sample of men convicted of intimate partner violence (N=265). This was carried out using the Spanish version of the Buss and Perry Aggression Questionnaire and the Melero and Cantero Adult Attachment Questionnaire. After the cleaning and analysis of the data by means of k-means cluster analysis, ANOVA and multiple hierarchical linear regression, it becomes clear that the fact of having been a victim of childhood abuse among this type of men, although it constitutes a risk factor for violent behavior in adult life, does not determine it. Something similar could be said about the different attachment styles, with secure types functioning as a protective factor and insecure types being associated to a greater extent and with different forms of violence.

The present study analyzes the psychometric properties of the Dimensional Self-Concept Questionnaire (AUDIM-M) in university men and women. The total sample was of 730 participants; 365 women and 365 men, with a means age of 20.55 years (SD = 1.87) and 20.78 years (SD = 1.90) respectively. According to the established psychometric requirements, the confirmatory factor analyzes showed that a four-factor structure (personal selfconcept, physical self-concept, social self-concept and academic self-concept) is viable and suitable for both populations (women and men). In addition, the factorial structure, the factorial loads and the intercepts are considered invariant in the two populations; however, there are differences between the populations for the means of the factors physical self-concept and social selfconcept.
