They may offer alternative explanations for their injuries, or conceal their scars with clothing. Self-harm in such individuals may not be associated with suicidal or para-suicidal behavior. People who self-harm are not usually seeking to end their own life; it has been suggested instead that they are using self-harm as a coping mechanism to relieve emotional pain or discomfort or as an attempt to communicate distress.Studies of individuals with developmental disabilities (such as intellectual disability) have shown self-harm being dependent on environmental factors such as obtaining attention or escape from demands. Some individuals may have dissociation harboring a desire to feel real or to fit into societys rules. Signs and symptoms
Eighty percent of self-harm involves stabbing or cutting the skin with a sharp object, sometimes breaking through the skin entirely. However, the number of self-harm methods are only limited by an individuals inventiveness and their determination to harm themselves; this includes burning, self-poisoning, alcohol abuse, self-embedding of objects, hair pulling, bruising/hitting ones self, scratching to hurt ones self, knowingly abusing over-the-counter or prescription drugs, and forms of self-harm related to anorexia and bulimia. The locations of self-harm are often areas of the body that are easily hidden and concealed from the detection of others. As well as defining self-harm in terms of the act of damaging the body, it may be more accurate to define self-harm in terms of the intent, and the emotional distress that the person is attempting to deal with. Neither the DSM-IV-TR nor the ICD-10 provide diagnostic criteria for self-harm.
However, females who self-cut are more likely than males to explain their self-harm episode by saying that they had wanted to punish themselves. In New Zealand, more females are hospitalized for intentional self-harm than males. Females more commonly choose methods such as self-poisoning that generally are not fatal, but still serious enough to require hospitalization. Elderly
In a study of a district general hospital in the UK, 5.4% of all the hospitals self-harm cases were aged over 65. The male to female ratio was 2:3 although the self-harm rates for males and females over 65 in the local population were identical. Over 90% had depressive conditions, and 63% had significant physical illness. Under 10% of the patients gave a history of earlier self-harm, while both the repetition and suicide rates were very low, which could be explained by the absence of factors known to be associated with repetition, such as personality disorder and alcohol abuse. However, NICE Guidance on Self-harm in the UK suggests that older people who self-harm are at a greater risk of completing suicide, with 1 in 5 older people who self-harm going on to end their life. A study completed in Ireland showed that older Irish adults have high rates of deliberate self-harm, but comparatively low rates of suicide. Developing world
Only recently have attempts to improve health in the developing world concentrated on not only physical illness but also mental health. Deliberate self-harm is common in the developing world.
