RESUMO
The aim of this work was to adapt and validate the Sibling Attachment Inventory (SAI) in Mexican young adults and analyze its psychometric properties. Using an Internet-based survey, data were collected from 307 (64.5% female) Mexican young adults university students (aged 18-30). Exploratory and confirmatory factor analyses were performed to determine the factor structure of the revised Mexican version of the Sibling Attachment Inventory (SAI-RMx). Convergent and predictive validity were verified by carrying out correlations with the parent form of the Inventory of Parent and Peer Attachment (IPPA), the Lifespan Sibling Relationship Scale (LSRS), the Satisfaction With Life Scale (SWLS), and the Rosenberg Self-Esteem Scale (RSE). Results indicated that the SAI-RMx presents good levels of internal consistency and a monodimensional structure, also providing evidence for convergent, predictive, and construct validity. Furthermore, secure attachments were linked with high levels of self-esteem, as well as with high levels of life satisfaction. The SAI-RMx is expected to be a reliable instrument for measuring the global level and the three components of secure attachment between siblings in the young adult's Mexican population.

El presente estudio tuvo como objetivo explorar el significado que una muestra de adolescentes y adolescentes tardíos del sur de Italia atribuye a las funciones familiares, para analizar la relación entre la percepción de las transformaciones de las funciones paternas y maternas en particular la carencia de roles normativos y de contención afectiva y la agresividad como modalidad preferencial de gestión del conflicto. Se aplicó un diferencial semántico (DF, De Rosa, Parrello, & Sommantico, 2006) y un instrumento de agresividad, adaptado a población europea (AQ, Buss & Perry, 1992, 2003) a 259 sujetos, de edad comprendida entre los 17 y los 35 años, divididos en dos grupos, 139 de bachillerato y 120 de licenciatura. Los resultados del análisis del DF indicaron un perfil monofactorial, a diferencia del trifactorial obtenido por Osgood, Suci y Tannembaum (1957), mientras que en el AQ se encontraron diferencias significativas entre la media de la agresividad general (ξ=2,73) y factores del instrumento como agresividad verbal (ξ=3,29), la rabia (ξ=2,86) y hostilidad (ξ=2,86). Se concluye que las cualidades de tamaño y seguridad le son atribuidas específicamente a la madre, y que el nivel de agresividad verbal supera el índice de agresividad general.
The main objective of this study was to explore the meaning attributed to family functions by a sample of adolescents and late adolescents of the southern part of Italy. Accomplishing this objective permitted to understand the relationship between the perception of the transformations in both paternal and maternal functions specifically the lack of normative roles and of affective containment- and aggressiveness as the most preferable manner to deal with conflict. A semantic differential (DF, De Rosa, Parrello and Sommantico, 2006) and an instrument for measuring aggressiveness, adapted for the European population (AQ Buss and Perry, 1992, 2003) was applied to 259 participants, ranging from 17 to 35 years old; participants were divided in two groups, 139 of them in high school and the other 120 in college. The results of the DF analysis indicated a monofactorial profile, different from the trifactorial profile obtained by Osgood, Suci, &Tannembaum (1957). In the AQ analysis, significant differences between the average of general aggressiveness (ξ = 2,73) and other factors evaluated by the aggressiveness instrument were found, such as verbal aggression (ξ =3,29), anger (ξ =2,86) and hostility (ξ=2,86). It is concluded that the qualities of size and security could be attributed specifically to the mother, and that the level of verbal aggression goes beyond any other index of general aggression.
