Research into self-harm in the developing world is however still very limited although an important case study is that of Sri Lanka, which is a country exhibiting a high incidence of suicide and self-poisoning with agricultural pesticides or natural poisons. Many people admitted for deliberate self-poisoning during a study by Eddleston et al. were young and few expressed a desire to die, but death was relatively common in the young in these cases. The improvement of medical management of acute poisoning in the developing world is poor and improvements are required in order to reduce mortality. Some of the causes of deliberate self-poisoning in Sri Lankan adolescents included bereavement and harsh discipline by parents. The coping mechanisms are being spread in local communities as people are surrounded by others who have previously deliberately harmed themselves or attempted suicide. One way of reducing self-harm would be to limit access to poisons; however many cases involve pesticides or yellow oleander seeds, and the reduction of access to these agents would be difficult. Great potential for the reduction of self-harm lies in education and prevention, but limited resources in the developing world make these methods challenging. Prison inmates
Deliberate self-harm is especially prevalent in prison populations. A proposed explanation for this is that prisons are often violent places, and prisoners who wish to avoid physical confrontations may resort to self-harm as a ruse, either to convince other prisoners that they are dangerously insane and resilient to pain or to obtain protection from the prison authorities.
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.
