“…In fact, our current understanding of indirect aggression has centered on a limited number of variables that have, for the most part, been examined concurrently, and have converged on rather similar findings. These studies have shown that: (1) older children use indirect aggression more than younger children [e.g., Bjorkqvist, 1994;Bjorkqvist et al, 1992a,b;Lagerspetz et al, 1988], (2) those who use indirect aggression and fall victim to such attacks tend to suffer from a host of psychosocial adjustment problems [e.g., Crick et al, 1997Crick et al, , 1999aMcNeilly-Choque et al, 1996], and (3) females tend to use indirect aggression more than males, who in turn use physical aggression more than females [e.g., Bonica et al, 2003;Crick, 1995Crick, , 1996Crick et al, 1997Crick et al, , 1999aCrick and Grotpeter, 1995;Feshbach, 1969Feshbach, , 1971Lagerspetz et al, 1988;McNeilly-Choque et al, 1996;Ostrov and Keating, 2004;Tapper and Boulton, 2004]. Some researchers have reported no sex differences in the use of indirect aggression [Hart et al, 1998;Willoughby et al, 2001], or sex differences in favor of males [David and Kistner, 2000;Hennington et al, 1998;McEvoy et al, 2003;Salmivalli and Kaukianen, 2004;Tomada and Schneider, 1997].…”
