Heath, Nancy L.; Toste, Jessica R.; Beettam, Erin L. – Canadian Journal of School Psychology, 2006
Fifty teachers completed a survey to investigate knowledge, self-perceived knowledge, and attitudes regarding self-injury (SI). Teachers were aware of basic facts concerning SI; however, 78% underestimated prevalence, and only 20% felt knowledgeable. Attitudes were mixed, with 48% finding the idea of SI horrifying; however, 68% disagreeing that SI…
