Sources of variance affecting receipt of aggression

36 boys and 33 girls from a suburban high school and 24 boys and 22 girls from an inner-city high school rated the frequency with which four other people hit or kicked them during the year. The four people were a brother, sister, non-family male (with whom they fought most during the year), and nonfamily female (with whom they fought most during the year). When responses were dichotomized into "hit" versus "not hit" by a particular person during the year, there was no effect of environment (suburban vs inner-city). The percentage of boys reporting being hit by girls was higher than the percentage of girls reporting being hit by girls. People with siblings were more likely to report being hit by them than by a nonfamily member (although frequency of contact might account for this finding).
