The relationship was examined between the self-reported cooperativeness of Australian secondary-school students and their involvement in peer abuse at school, both as bullies and as victims. An 18-item Likert-type measure, the Cooperativeness Scale, was developed, and its reliability and concurrent validity were supported by the results of its application to two samples of Australian students (N = 176 and N = 763, respectively) attending different coeducational secondary schools, the first in a predominantly middle-class area and the second in a lower class socioeconomic area. At both schools, girls scored higher in cooperativeness than boys. Students at the second school also anonymously completed multiple measures of the extent of their involvement during the current year in bullying, victimization, or both. As predicted, correlations and multiple regression analyses supported the hypothesis that relatively low levels of cooperativeness were characteristic, not only of both boys and girls who engaged in bullying, but also, to a lesser extent, of those who were frequently victimized by their peers at school.
