Both Males and Females Self-harm
As noted in previous blogs, although some studies found that females were more likely to self-harm than men (World Health Organization, 1989), more recent estimates suggest that males may be just as likely as females to self-harm (e.g., Gratz, 2001; Gratz & Chapman, 2007; Klonsky, Oltmanns, & Turkheimer, 2003).
Self-harm is More Common in Adolescence to Early Adulthood
Self-harm typically begins in adolescence. Generally, the rates of self-harm are highest between age fourteen to about mid-twenties (Ross & Heath, 2002), although many people who self-harm are much younger or older (Auseinet, 2007; Pierce, 1987). Self-harm is much more rare among people older than 35 years old.
