“…A single item question rendered a prevalence rate of 17% in a study measuring DSH, without differentiating on the basis of intent (Landstedt & Gillander Gådin, 2011). Internationally, prevalence rates of NSSI in community samples of adolescents usually range somewhere between 13-25% around the world (Baetens et al, 2011;Brunner et al, 2007;Brunner et al, 2014;Guan et al, 2012;Hankin & Abela, 2011;Jacobson & Gould, 2007;Laye-Gindhu & Schonert-Reichl, 2005;Martin, Swannell, Hazell, Harrison, & Taylor, 2010;Muehlenkamp & Gutierrez, 2004;Muehlenkamp, Williams, Gutierrez, & Claes, 2009;Nixon, Cloutier, & Jansson, 2008;Plener, Libal, Keller, et al, 2009;Plener et al, 2013;Tolmunen et al, 2008;You, Leung, Fu, & Lai, 2011;Zoroglu et al, 2003).
