There are a number of different methods that can be used to treat self-harm, which concentrate on either treating the underlying causes or on treating the behavior itself. Other approaches involve avoidance techniques, which focus on keeping the individual occupied with other activities, or replacing the act of self-harm with safer methods that do not lead to permanent damage.
Self-harm is most common between the ages of 12 and 24.
Self-harm in childhood is relatively rare, but the rate has been increasing since the 1980s.
Self-harm can also occur in the elderly population.
The risk of serious injury and suicide is higher in older people who self-harm.
Captive animals, such as birds and monkeys, are also known to participate in self-harming behavior.
Classification
Self-harm (SH), also referred to as ''self-injury'' (SI), ''self-inflicted violence'' (SIV), ''nonsuicidal self injury'' (NSSI) or ''self-injurious behavior'' (SIB), are different terms to ascribe behaviors where demonstrable injury is self-inflicted.
The behavior involves deliberate tissue damage that is usually performed without suicidal intent. The most common form of self-harm involves cutting of the skin using a sharp object, e. g. a knife or razor blade. The term ''self-mutilation'' is also sometimes used, although this phrase evokes connotations that some find worrisome, inaccurate, or offensive.

Self-inflicted wound
A self-inflicted wound (SIW), is the act of harming oneself where there are no underlying psychological problems related to the self-injury, but where the injurer wanted to take advantage of being injured.

s'' is a specific term associated with soldiers to describe non-lethal injuries inflicted in order to obtain early dismissal from combat. This differs from the common definition of self-harm, as damage is inflicted for a specific secondary purpose. A broader definition of self-harm might also include those who inflict harm on their bodies by means of
disordered eating.
The older literature has used several different terms. For this reason research in the past decades has inconsistently focused on self-harming behavior without and with suicidal intent (including suicide attempts) with varying definitions leading to inconsistent and unclear results.
Nonsuicidal self-injury (NSSI) has been listed in section 2 of the DSM-5-TR under the category "other conditions that may be a focus of clinical attention".
While NSSI is not a separate mental disorder, the DSM-5-TR adds a diagnostic code for the condition in-line with the
ICD

. The disorder is defined as intentional self-inflicted injury without the intent of dying by suicide. Criteria for NSSI include five or more days of self-inflicted harm over the course of one year without suicidal intent, and the individual must have been motivated by seeking relief from a negative state, resolving an interpersonal difficulty, or achieving a positive state.
A common belief regarding self-harm is that it is an

engage in self-harm. An estimated 30% of individuals with
autism spectrum disorders engage in self-harm at some point, including eye-poking,
skin-picking, hand-biting, and head-banging.
Schizophrenia may also be a contributing factor for self-harm. Those diagnosed with schizophrenia have a high risk of suicide, which is particularly greater in younger patients as they may not have an insight into the serious effects that the disorder can have on their lives. There are parallels between self-harm and
Münchausen syndrome

, a psychiatric disorder in which individuals feign illness or trauma.
There may be a common ground of inner distress culminating in self-directed harm in a Münchausen patient. However, a desire to deceive medical personnel in order to gain treatment and attention is more important in Münchausen's than in self-harm.
Psychological factors
Self-harm is frequently described as an experience of
depersonalization or a
dissociative state. Abuse during childhood is accepted as a primary social factor increasing the incidence of self-harm,
as is
bereavement,
and troubled parental or partner relationships.
Factors such as war, poverty, unemployment, and substance abuse may also contribute.
Other predictors of self-harm and suicidal behavior include feelings of entrapment, defeat, lack of belonging, and perceiving oneself as a burden along with having an impulsive personality and/or less effective social problem-solving skills.
The onset of puberty, including the onset of sexual activity, often correlates with the onset of self-harm; this is because the pubertal period is associated with neurodevelopmental vulnerability and comes with an increased risk of emotional disorders and risk-taking behaviors.

Genetics may contribute to the risk of developing other psychological conditions, such as anxiety or depression, which could in turn lead to self-harming behavior. However, the link between genetics and self-harm in otherwise healthy patients is largely inconclusive.

Pathophysiology
![Self-injury](https://upload.wikimedia.org/wikipedia/commons/e/ea/Self-injury.svg)
Self-harm is not typically suicidal behavior, although there is the possibility that a self-inflicted injury may result in life-threatening damage.
Although the person may not recognise the connection, self-harm often becomes a response to profound and overwhelming emotional pain that cannot be resolved in a more functional way.
The motivations for self-harm vary, as it may be used to fulfill a number of different functions.
These functions include self-harm being used as a coping mechanism which provides temporary relief of intense feelings such as anxiety, depression, stress, emotional numbness and a sense of failure or
self-loathing
Self-hatred is personal self-loathing or hatred of oneself, or low self-esteem which may lead to self-harm.

. There is also a positive statistical correlation between self-harm and emotional abuse.

pain
Pain is a distressing feeling often caused by intense or damaging stimuli. The International Association for the Study of Pain defines pain as "an unpleasant sensory and emotional experience associated with, or resembling that associated with, ...
, in contrast to the pain experienced earlier in the person's life over which they had no control (e.g., through abuse).
Other motives for self-harm do not fit into medicalized models of behavior and may seem incomprehensible to others, as demonstrated by this quotation:
"My motivations for self-harming were diverse, but included examining the interior of my arms for hydraulic lines. This may sound strange."
Assessment of motives in a medical setting is usually based on precursors to the incident, circumstances, and information from the patient.
However, limited studies show that professional assessments tend to suggest more manipulative or punitive motives than personal assessments.

study reported only two motives: "to draw attention" and "because of anger".
For some people, harming themselves can be a means of drawing attention to the need for help and to ask for assistance in an indirect way. It may also be an attempt to affect others and to manipulate them in some way emotionally.
However, those with chronic, repetitive self-harm often do not want attention and hide their scars carefully.
Many people who self-harm state that it allows them to "go away" or
dissociate, separating the mind from feelings that are causing anguish. This may be achieved by tricking the mind into believing that the present suffering being felt is caused by the self-harm instead of the issues they were facing previously: the
physical pain
Pain is a distressing feeling often caused by intense or damaging stimuli. The International Association for the Study of Pain defines pain as "an unpleasant sensory and emotional experience associated with, or resembling that associated with, ...
therefore acts as a distraction from the original emotional pain.
To complement this theory, one can consider the need to "stop" feeling emotional pain and mental agitation. "A person may be hyper-sensitive and overwhelmed; a great many thoughts may be revolving within their mind, and they may either become triggered or could make a decision to stop the overwhelming feelings."
Alternatively, self-harm may be a means of feeling ''something'', even if the sensation is unpleasant and painful. Those who self-harm sometimes describe feelings of
emptiness
Emptiness as a human condition is a sense of generalized boredom, social alienation and apathy. Feelings of emptiness often accompany dysthymia, depression (mood), depression, loneliness, anhedonia,

), and physical pain may be a relief from these feelings. "A person may be detached from themselves, detached from life, numb and unfeeling. They may then recognise the need to function more, or have a desire to feel real again, and a decision is made to create sensation and 'wake up'."
Those who engage in self-harm face the contradictory reality of harming themselves while at the same time obtaining relief from this act. It may even be hard for some to actually initiate cutting, but they often do because they know the relief that will follow. For some self-harmers this relief is primarily psychological while for others this feeling of relief comes from the
beta endorphins released in the brain.
Endorphins are endogenous opioids that are released in response to physical injury, acting as natural painkillers and inducing pleasant feelings, and in response to self-harm would act to reduce tension and emotional distress.
Many self-harmers report feeling very little to no pain while self-harming
and, for some, deliberate self-harm may become a means of seeking pleasure.
As a coping mechanism, self-harm can become psychologically

Addiction is a neuropsychological disorder characterized by a persistent and intense urge to engage in certain behaviors, one of which is the usage of a drug, despite substantial harm and other negative consequences. Repetitive drug use oft ...
because, to the self-harmer, it works; it enables them to deal with intense stress in the current moment. The patterns sometimes created by it, such as specific time intervals between acts of self-harm, can also create a behavioral pattern that can result in a wanting or craving to fulfill thoughts of self-harm.

Emotional pain activates the same regions of the brain as physical pain, so emotional stress can be a significantly intolerable state for some people. Some of this is environmental and some of this is due to physiological differences in responding. The

controls physical processes that are automatic (e.g., saliva production). The sympathetic nervous system innervates (e.g., is physically connected to and regulates) many parts of the body involved in stress responses. Studies of adolescents have shown that adolescents who self-injure have greater physiological reactivity (e.g., skin conductance) to stress than adolescents who do not self-injure. This stress response persists over time, staying constant or even increasing in self-injuring adolescents, but gradually decreases in adolescents who do not self-injure.

At the same time, according to a study conducted in England, people who self-harm often experience that they don't receive meaningful care at the emergency department. Both people who self-harm and staff in the study highlighted the failure of the healthcare system to support, the lack of specialist care. People who self-harm in the study often felt shame or being judged due to their condition, and said that being listened to and validated gave them hope. At the same time staff experienced frustration from being powerless to help and were afraid of being blamed if someone commits suicide.
Therapy
Dialectical behavior therapy for adolescents (DBT-A) is a well-established treatment for self-injurious behavior in youth and probably useful for decreasing the risk of non suicidal self injury.
Several other treatments including integrated CBT (I-CBT), attachment-based family therapy (ABFT), resourceful adolescent parent program (RAP-P), intensive interpersonal psychotherapy for adolescents (IPT-A-IN), mentalization-based treatment for adolescents (MBT-A), and integrated family therapy are probably efficacious.

Dialectical behavior therapy (DBT) can be successful for those individuals exhibiting a personality disorder, and could potentially be used for those with other mental disorders who exhibit self-harming behavior.
Diagnosis and treatment of the causes of self-harm is thought by many to be the best approach to treating self-harm.
But in some cases, particularly in people with a personality disorder, this is not very effective, so more clinicians are starting to take a DBT approach in order to reduce the behavior itself. People who rely on habitual self-harm are sometimes hospitalized, based on their stability, their ability and especially their willingness to get help.

Psychological therapies with the largest effect sizes were dialectical behavior therapy (DBT), cognitive-behavioral therapy (CBT), and mentalization-based therapy (MBT).
In individuals with developmental disabilities, occurrence of self-harm is often demonstrated to be related to its effects on the environment, such as obtaining attention or desired materials or escaping demands. As developmentally disabled individuals often have communication or social deficits, self-harm may be their way of obtaining these things which they are otherwise unable to obtain in a socially appropriate way (such as by asking). One approach for treating self-harm thus is to teach an alternative, appropriate response which obtains the same result as the self-harm.
Avoidance techniques
Generating alternative behaviors that the person can engage in instead of self-harm is one successful behavioral method that is employed to avoid self-harm.
Techniques, aimed at keeping busy, may include journaling, taking a walk, participating in sports or exercise or being around friends when the person has the urge to harm themselves.
The removal of objects used for self-harm from easy reach is also helpful for resisting self-harming urges.
The provision of a card that allows the person to make emergency contact with counselling services should the urge to self-harm arise may also help prevent the act of self-harm.
Alternative and safer methods of self-harm that do not lead to permanent damage, for example the snapping of a rubber band on the wrist, may also help calm the urge to self-harm.

may help raise self-awareness of certain pre-occupations or particular mental state or mood that precede bouts of self-harming behavior,
and help identify techniques to avoid those pre-occupations before they lead to self-harm. Any avoidance or coping strategy must be appropriate to the individual's motivation and reason for harming.
Epidemiology
![Self-inflicted injuries world map - DALY - WHO2004](https://upload.wikimedia.org/wikipedia/commons/6/61/Self-inflicted_injuries_world_map_-_DALY_-_WHO2004.svg)
It is difficult to gain an accurate picture of incidence and prevalence of self-harm.
This is due in a part to a lack of sufficient numbers of dedicated research centres to provide a continuous monitoring system.
However, even with sufficient resources, statistical estimates are crude since most incidences of self-harm are undisclosed to the medical profession as acts of self-harm are frequently carried out in secret, and wounds may be superficial and easily treated by the individual.
Recorded figures can be based on three sources: psychiatric samples, hospital admissions and general population surveys.
The World Health Organization estimates that, as of 2010, 880,000 deaths occur as a result of self-harm.
About 10% of admissions to medical wards in the UK are as a result of self-harm, the majority of which are
drug overdose
A drug overdose (overdose or OD) is the ingestion or application of a drug or other substance in quantities much greater than are recommended. s.
However, studies based only on hospital admissions may hide the larger group of self-harmers who do not need or seek hospital treatment for their injuries,
instead treating themselves. Many adolescents who present to general hospitals with deliberate self-harm report previous episodes for which they did not receive medical attention.
In the United States up to 4% of adults self-harm with approximately 1% of the population engaging in chronic or severe self-harm.
Current research suggests that the rates of self-harm are much higher among young people
with the average age of onset between 14 and 24.
The earliest reported incidents of self-harm are in children between 5 and 7 years old.
In the UK in 2008 rates of self-harm in young people could be as high as 33%.
In addition there appears to be an increased risk of self-harm in college students than among the general population.
In a study of undergraduate students in the US, 9.8% of the students surveyed indicated that they had purposefully cut or burned themselves on at least one occasion in the past. When the definition of self-harm was expanded to include head-banging, scratching oneself, and hitting oneself along with cutting and burning, 32% of the sample said they had done this. In Ireland, a study found that instances of hospital-treated self-harm were much higher in city and urban districts, than in rural settings.
The CASE (Child & Adolescent Self-harm in Europe) study suggests that the life-time risk of self-injury is ~1:7 for women and ~1:25 for men.
Gender differences
In general, the latest aggregated research has found no difference in the prevalence of self-harm between men and women.
This is in contrast to past research which indicated that up to four times as many females as males have direct experience of self-harm.
However, caution is needed in seeing self-harm as a greater problem for females, since males may engage in different forms of self-harm (e.g., hitting themselves) which could be easier to hide or explained as the result of different circumstances.
Hence, there remain widely opposing views as to whether the gender paradox is a real phenomenon, or merely the artifact of bias in data collection.

/EURO Multicentre Study of Suicide, established in 1989, demonstrated that, for each age group, the female rate of self-harm exceeded that of the males, with the highest rate among females in the 13–24 age group and the highest rate among males in the 12–34 age group. However, this discrepancy has been known to vary significantly depending upon population and methodological criteria, consistent with wide-ranging uncertainties in gathering and interpreting data regarding rates of self-harm in general. Such problems have sometimes been the focus of criticism in the context of broader psychosocial interpretation. For example, feminist author Barbara Brickman has speculated that reported gender differences in rates of self-harm are due to deliberate socially biased methodological and sampling errors, directly blaming medical discourse for pathologising the female.
This gender discrepancy is often distorted in specific populations where rates of self-harm are inordinately high, which may have implications on the significance and interpretation of psychosocial factors other than gender. A study in 2003 found an extremely high prevalence of self-harm among 428 homeless and runaway youths (aged 16–19) with 72% of males and 66% of females reporting a history of self-harm. However, in 2008, a study of young people and self-harm saw the gender gap widen in the opposite direction, with 32% of young females, and 22% of young males admitting to self-harm.
Studies also indicate that males who self-harm may also be at a greater risk of completing suicide.
There does not appear to be a difference in motivation for self-harm in adolescent males and females. Triggering factors such as low self-esteem and having friends and family members who self-harm are also common between both males and females.
One limited study found that, among those young individuals who do self-harm, both genders are just as equally likely to use the method of skin-cutting. 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 hospital's 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. 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

s 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

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. Self-harm also occurs frequently in inmates who are placed in

refined his conceptual definitions of self-mutilation. His study on self-destructiveness differentiated between suicidal behaviors and self-mutilation. For Menninger, self-mutilation was a non-fatal expression of an attenuated death wish and thus coined the term ''partial suicide''. He began a classification system of six types:
# neurotic –
nail-biters, pickers, extreme hair removal and unnecessary cosmetic surgery.
# religious – self-flagellants and others.

diagnosis. The "coarse" cutters were older and generally psychotic.
Ross and McKay (1979) categorized self-mutilators into 9 groups: ''cutting'', ''biting'', ''abrading'', ''severing'', ''inserting'', ''burning'', ''ingesting or inhaling'', ''hitting'', and ''constricting''.
After the 1970s the focus of self-harm shifted from
Freudian psycho-sexual drives of the patients.
Walsh and Rosen (1988) created four categories numbered by Roman numerals I–IV, defining ''Self-mutilation'' as rows II, III and IV.
Favazza and Rosenthal (1993) reviewed hundreds of studies and divided self-mutilation into two categories: ''culturally sanctioned self-mutilation'' and ''deviant self-mutilation''.
Favazza also created two subcategories of sanctioned self-mutilations; ''rituals'' and ''practices''. The ''rituals'' are mutilations repeated generationally and "reflect the traditions, symbolism, and beliefs of a society" (p. 226). ''Practices'' are historically transient and cosmetic such as piercing of earlobes, nose, eyebrows as well as male circumcision (for non-Jews) while ''Deviant self-mutilation'' is equivalent to self-harm.

Self-harm in non-human mammals is a well-established but not widely known phenomenon. Its study under zoo or laboratory conditions could lead to a better understanding of self-harm in human patients.
Zoo or laboratory rearing and isolation are important factors leading to increased susceptibility to self-harm in higher mammals, e.g., macaque monkeys.
Non-primate mammals are also known to mutilate themselves under laboratory conditions after administration of drugs.
