The present study investigated externalizing and internalizing behaviours in Greek (n = 599), Russian (n = 596), Indian (n = 571), and Chinese (n = 376) 7- to 12-year-old children. The Fairy Tale Test was used to measure impulsive and motivated aggression, fear of aggression, anxiety, and depression. The results indicated culture-specific patterns of the aforementioned behaviours. Greek children demonstrated the highest levels of impulsive and motivated aggression, while Russian children had the highest fear of aggression. Chinese children appeared to be most anxious among other cultural groups. Both Russian and Indian children were more depressed than their Greek and Chinese counterparts. Gender and age difference were obtained only for impulsive aggression. Regardless of culture, boys scored higher compared to girls; and 7- to 8-year-old children demonstrated higher level of impulsive aggression than older children. The obtained results are interpreted in light of contextual differences in child socialization in four cultures; suggestions for school psychology practices are offered. (Contains 2 tables.)
