Two self-report inventories developed to assess different dimensions of aggression, the Aggression Questionnaire and the EXPAGG, were administered to a sample (N = 400) of men and women undergraduates in two Japanese and Spanish universities. The factor structure of scales was assessed using exploratory factor analysis. Both questionnaires showed high correlations between their respective scales. In both cultures, males reported more physical aggression, verbal aggression, and hostility as well as higher instrumental beliefs, whereas females reported more expressive representation than males. Japanese students reported more physical aggression than their Spanish counterparts, who reported more verbal aggression, hostility, and anger and more expressive representation of aggression. Aggr. Behav. 27:313-322, 2001.

A total of 221 responses were obtained from a survey of international students in Japan, regarding the facilitative effects of social network formation on their adjustment. Regression analyses were conducted to explore the relationships among four types of adjustment revealed in a preceding study ("general adjustment," "self-control," "affiliative" and "dependent"), network size, demographic variables, expected social support, etc. For each adjustment type, predictive variables were identified. Two of the variables that showed network effects on adjustment were Japanese language proficiency and race (Asians vs. Westerners). From these results, it would appear that social network formation does facilitate adjustment, and insight into the effect of adjustment type and demographic variables on network functions was obtained. Furthermore, the actual conditions regarding network formation of international students in Japan were revealed.
