This is from a paper I wrote last year, and I didn't paste the bibliography cause it's really long.
Many studies have been performed regarding bullying in the schools. Nansel, Overpeck, Pilla, Ruan, Simons-Morton, & Scheidt (2001) showed that bullying was more common between grades 6-8 than 9-10th grade (as cited in Chapell et al., 2004). A bullied child exhibits reactions such as school avoidance, low self-esteem, anxiety, depression, and thoughts of suicide more so than those who weren’t bullied (Chapell et al.). According to a few studies (Glendenning, 2001; O’Moore, Seigne, McGuire, and Smith, 1998; Quine, 2001; Rayner, 1997), bullying takes place beyond high school occurring more often in adult, office environments (as cited in Chapell et al.). According to a few studies (Baldry & Farrington, 1998; Olweus, 1980; Rigby, 1996), authoritarian parenting methods are correlated to child bullies (as cited in Chapell et al.). For college aged adults (n=1,025), 60% saw another student being bullied by another student while 44% saw teachers doing the bullying (Chapell et al.).
