| Abstract: | The aim of this multimethod, longitudinal study was to examine similarities and differences in aggressive expression and prediction among school-aged boys and girls. The primary research sample involved 174 children (93 females, 81 males). They were in the fourth grade at the beginning of the study, and the fifth grade at its conclusion. Embedded in the primary sample was a subgroup of 20 children identified as being highly aggressive (ten males, ten females), and a subgroup of 20 matched control children. The research measures included teachers' ratings of aggressive behavior, peer-nominations/reports of prior conflicts, individual interviews/self-ratings, and extensive behavioral observations. Analyses of the concurrent relations among measures pointed to a “public” cluster of measures (including peer-nominations, behaviors, and teacher ratings) and relatively “private” measures (ie, subjects' self-evaluations). In the primary sample, significant developmental trends were detected in the teacher ratings with increasing gender differentiation as children grew older. Few gender differences were observed in the high-aggressive subgroup, but the aggressive and the matched control groups differed on virtually all comparisons. Gender differences in predictability were a function of risk status, with high-aggressive girls showing as much stability as high-aggressive boys. |
