I realize this is a very, very old thread, but there's something I would like to point out:
Self-harm/Self-injury and self-mutilation are two very different things. Self-mutilation is a very, very severe form of self-harm/injury (those two terms are synonymous). Examples may include limb amputation, cutting or tearing out larger chunks of flesh, intentional breaking of bones, extremely deep cutting (not to go TOO deep into graphic detail, but say, three or four inches into tissue), second or third degree burns, shooting one's self non-fatally, and other things of that nature.
Self-injury/self-harm are more of the commonly thought cutting or burning behaviors. It can also take the form of excessive drinking, binging and purging, restricting as in refraining from eating as a client with anorexia nervosa would, abusing drugs, dermotillomania (compulsive skin picking), trichotillomania (compulsive hair pulling) and things that may not typically be though of as self-harming or self-injurious.
I merely bring this up because in a clinic setting, there would be a specific differentiation, and on the site itself [though I'm not sure whose attention I would bring this to], I feel self-mutilation and self-harm should be two separate categories of mental health issues.
While I'm not a clinician or an expert, I am a clinical psychology student and a clinical psychology patient that's been in therapy of many types, including talk therapy, CBT, a modified for of CBT known as CBT-i, DBT, Schema Therapy, Interpersonal Therapy, Intensive Outpatient Therapy for Binge Eating Disorder NOS/Unspecified, general group therapy, as well having been treated in-patient at one point. Different disorders are listed openly and honestly on my profile page. I've been in the American Behavioral Health System since I was 15 and am now almost 22, giving seven years of empirical experience. I just wanted to justify my concerns and back-up my knowledge with some sort of credentials. It's worrisome for me as it's potentially confusing for those who may use the terms interchangeably with an mental health practitioner and worsen the situation for themselves by unintentionally over-stating the extent of the wounds or understating the extent of necessity of treatment.
