Term history

In the United StatesWrist cutSelf-harm like this has been popular since the 1960s[5].. 1990年代以前には、自傷行為を表す英単語としてself-mutilationという語が使われていたが、mutilationとは機能不全にするように切断するというような意味であり、1990年代半ばからself-injuryという語に置き換わっていったBefore the XNUMXs, the word self-mutilation was used as an English word for self-harm, but mutilation means cutting to make it dysfunctional, and since the mid-XNUMXs self-mutilation. It was replaced by the word injury[6]..偶発的に起こることではないIt's not something that happens accidentally[7]..In 1999 in JapanSteven LevenkronThe translator who translated "Self-harm Girl" into Japanese introduced in the postscript that the word "self-harm" is unfamiliar, and it will be a problem in Japan after that.[5].

In 1983, Pattison and Kahan proposed the concept of "Deliberate self-harm syndrome", the three signs of which are "substance abuse or addiction," "self-harm," and "eating behavior." "Abnormal" was mentioned[8]..女性ではFor womenEating disorderIt is said that 60 to 70% of men are accompanied by self-harm, and more than 50% of substance abuse is accompanied by self-harm, which may be related as a common pathology or a common acting out factor.

Body modificationタ ト ゥ ー,EarringsThese are culturally endorsed, symbolic or aesthetically pleasing in most cultures, and although it is inappropriate to consider them as self-harm, they take such an aesthetic point of view. Can be self-harm if given by oneself in the absence, especially if it is done impulsively motivated to escape psychological distress[9]..アメリカでタトゥー、ピアスを自傷行為と考える専門家は80〜90%であったが、2000年半ばには5〜10%であり、ゆえに社会的に容認されていれば、身体改造を自傷と考えることは不適切であるIn the United States, XNUMX-XNUMX% of experts consider tattoos and piercings to be self-harm, but in mid-XNUMX it was XNUMX-XNUMX%, so if socially acceptable, body modification would be self-harm. Is inappropriate to think[9].

Distinguishing between self-harm and suicide

Self-harm and suicide are strictly different.Misunderstanding self-harm as suicide hinders treatment (Lineham, 1993a)[Detailed information for identifying documents]).

suicideHowever, it is motivated by the desire to end consciousness and to stay away from pain forever.[10]..自傷に多い、切るという方法は、自殺では1.4%の者しかとらないOnly XNUMX% of people commit suicide by cutting, which is common in self-harm.[10].

Self-harm is to relieve and change psychological distress, as many self-harms self-report, while a few say that robotic emotional emptiness is distressing and escapes from it. Report[10]..自傷では、切る、火傷、殴る、頭をぶつける、タトゥー、ピアス、抜毛など、極端な事例を除けば死に至る可能性は低く、自殺とは異なり反復的に行われ、その部位も選択されているSelf-harm is unlikely to result in death except in extreme cases, such as cutting, burns, hitting, hitting the head, tattoos, piercings, and plucking. Are[11]..そうではなく、より強く傷をつける場合には、行動のコントロールができなくなっていることを示唆し、自傷というよりは上述したself-mutilationであるInstead, if you hurt more strongly, it suggests that you are out of control of your behavior, and it is the self-mutilation mentioned above rather than self-harm.[11].


Sadness and anger,孤独When feelings such as feelings and inferiority complex make the urge uncontrollable, orDifficulty breathing,headache, Nausea, etc.stressIt is generally said that when the symptoms caused by the above occur at the same time, they hurt themselves in order to suppress them.However, it is usually unclear to the individual what exactly triggers the self-harm.自傷を行う者は「ただ強い衝動があった」などといったはっきりとしない妙な説明をしてしまうことが多く、中には自傷をしている時点でThose who do self-harm often give unclear and strange explanations such as "I just had a strong urge", and some of them at the time of self-harmMemory,ConsciousnessThere may be no.これはいわゆるThis is so-calledDissociative disorderSeems to be.

The purpose is to reach deathsuicideRather, it is an act in which the desire to live appears in a refracted form, such as "reconfirmation of oneself" and "stress relief" to dispel the feeling of loneliness and emptiness.However, although self-harm is an act of wanting to live, the person often has suicidal ideation.Self-harm helps prevent suicide, but suicidal ideation can eventually lead to suicide.However, it is difficult to distinguish between accidental death and suicide due to self-harm, and the actual situation is not clear.Self-harm is often regarded as mysterious and difficult to understand in society.However, it is necessary to understand it as a danger signal for the person's condition.

Doctors may also suspect a brain organic disorder at first, but that is just a precaution.肉体を切るとWhen you cut your bodyEndorphinTo sayhormoneIs secreted and mental pain is relieved, so it is thought that some people unconsciously expect it and cut it.だが、大抵本人はこの事は分かっていないBut most of the time he doesn't know this[Source required].

Mental illness

The most suspected of self-harmBorderline personality disorder[3],Dissociative identity disorder.DSM-IV-TRThe fifth diagnostic criterion for borderline personality disorder includes "repeated suicide, pretense, intimidation, or self-harm."この他にはBesides thisdepression[3],Bipolar disorder[3]Histrionic personality disorder,Narcissistic personality disorder,Obsessive-compulsive disorderEtc. are also suspected.Also,schizophreniaMay be judged[3].

PsychiatryAbove is self-harmPersonality disorder,Dissociative disorderSuch asMental disorderIt is considered to be a secondary symptom of, and is not considered to occur alone.However, in reality, it has been found that the severity of symptoms does not always match the severity of self-harm.This seems to depend on whether or not the person has an "identity as a self-harm (wrist cutter)".これはかつて多くの精神病者と病院との間の関係でThis was once the relationship between many mentally ill people and hospitalsSociologyIt was pointed out by the people, and it is said that it is because the friendship at the hospital becomes steady and the consciousness that "I am a healthy person" is lost.

Drugs and alcohol

Alcohol abuse,Substance abuseRelated to[3].. At the age of 10-24SSRIThe results have shown that antidepressants of the system increase self-harm, with the frequency of self-harm doubling, especially when started at high doses.[12].

Genetic and biochemical factors

In the brain as a cause of self-harmSerotoninInactivity is also considered.しかし、そのBut thatBiochemistryAt this time, no conclusions have been reached as to whether the factor is identical to the genetic factor, as it is also said to be formed by trauma in early childhood.

AlcoholismSuch asHeredityTarget factors are thought to be factors that make self-harm worse.

Lack of self-ownership of the body

In some cases, the sense of ownership of one's body is weak, and the problem of the underlying pathology can be pointed out, but the direct causal relationship with self-harm is unknown.There is no view that a socio-cultural system such as the patriarchal system causes a vague perception that one's body is not one's own.There are no reliable reports that the patriarchal system is long like the Islamic society, and even now, self-harm in extremely strong countries is more common than in developed countries such as Japan.

Relevance to abuse

Abused people do not necessarily self-harm.

Kagoshima Universityが2006年1月に発表した、九州の5大学に通う1〜2年生1626人を対象にした調査がある。回答者1592人(男性831人、女性761人)のうち、自傷行為の経験者は120人(7.5%)であり、「家族からの放任や罵倒などを経験した」と答えた人が自傷行為をする危険性は、そうでない人の8.7倍、「第三者からの性的暴力を受けた」が5.8倍、「教師や友人からの無視を経験した」が5.5倍、「両親からかわいがられた経験がない」が4.2倍であった[Detailed information for identifying documents].

About direct motive

As a cause,FreudRelated toPsychoanalysisSometimes the interpretation of[13], Currently not so influential.精神分析学的PsychoanalyticEgo psychologyAccording to the interpretation related to, self-harm is caused by anxiety about separation from the mother when she was a child (around 1 to 3 years old), and it is claimed that it is used as a temporary means of confirming self-existence.この説はThis theoryPsychoanalysisThis happened because it was thought that the wrist was touching the breast and that it was trying to communicate with the mother.Based on this theory, self-harm is considered to be a type of communication with others such as mothers.However, first of all, if the wrist expresses communication with the mother, this theory is often inadequate at the time of leg cutting.Moreover, many patients continued to self-harm, although some were successful in actually improving their ability to communicate.For this reason, researchers have determined that self-harm has more complex causes, and the theory that there may be different causes is currently prevailing.In any case, we must be fully aware that the background differs from person to person.

It is known that in the case of self-harm, it may or may not dissociate.Many seem to use the two properly.The typical motives are described below, but it is not possible to clearly distinguish which one.However, the more dissociated it is, the more severe it is.

Try to attract the eyes and attention of the surroundings
This is done to satisfy the desire to intentionally make eye-catching scratches and be worried because we want to overcome the feeling of being abandoned, such as not being worried or seen by others.わざととはいっても、この動機はOn purpose, this motive is無意識It is a typical thing, and the person himself does not clearly understand it.Dissociative self-harm is almost the opposite, and in most cases, the wound is shown off without trying to hide it from the beginning.
Perform as a ritual
This is done when you lose your lover or family in an accident.In this case, the act of self-harm is considered to be the way of the funeral of the person himself / herself.If the contact with the family or lover is weak, even if you try to visit the grave, you cannot go, and it is said that it is performed as a funeral ceremony for the death of the lover or family by cutting your wrist or arm and bleeding.In this case, it is often the case that they could not afford to be sad at first due to work or personal circumstances, and it is said that it often occurs a year later.
BibleSome of them describe self-harm as a religious ritual.[14][15].
Means for recognizing oneself
This is done to reconfirm the outline of your existence and suppress the feeling of self-disassembly.This is to deny the idea that "I may not be necessary in this world" when I feel abandoned by others.This is also the case when one's existence is projected onto the pain due to being abused.It is done because you can feel relieved by reconfirming your own life by seeing pain and flowing blood.
Means to seek help by pain
This is done when you seek help from the pain itself when you are in a very dangerous situation.It is said that this is to imitate suicide and suppress one's own desire to commit suicide.For example, this is the case when you hesitate to die even though you want to escape from this reality due to a work failure.
Direct the urge to attack yourself
This is done when a person (often women) who cannot direct his or her own aggression impulse outwards directs the impulse inward.For example, this is done when you realize that you cannot forgive your existence that is not loved by your parents or those around you.It can also be interpreted that when you get angry at the surroundings who do not understand you, you personalize and attack the wrists and the like as if they were around them.
Means of escapism
If you run into something very difficult, use it to temporarily deal with that reality by cutting yourself.For example, if you realize that you don't need to love your parents because of your parents' discord or abuse of yourself, or if your friendship is cracked because of you, you must be yourself. This is the case when you think "I'm glad".In this case, it is considered that they are begging for "forgiveness" by being punished.However, it does not really give forgiveness, and it is said that addiction will progress.
Means to make yourself another person
It is used as a means of separating oneself by seeing what one is doing with the eyes of others.By slashing yourself and making your normal struggling self unbelievable, by treating yourself like others, denying yourself, and recognizing another self who is not. , Deny oneself who is in conflict with each other, and gain mental stability.
Means to eliminate one's own existence
Use it as a means of losing your past experiences and memories.The conflict of "parent murder" may occur in the person.The situation is also described as "pure white."It transcends one's own mental pain with physical pain, thereby destroying thoughts and regressing oneself inward.In other words, I feel that there is no one who can protect me mentally other than my own physical pain.


Early symptoms

Self-harm, including wrist cuts, begins精神It is often several years behind the most unstable period, starting around the age of 10 at the youngest.It may be started with alcohol or medicine, but in many cases it develops spontaneously.The initial feeling was strong resentment,不安,パ ニ ッ クAnd so on.As a precursor, they may throw or destroy things in an attempt to suppress their emotions.

Initially, the wound is often hidden from shame on the surroundings.通常はNormally腕 時 計,WristbandHide the wound with long sleeves.<span>Grade 1-2</span>For example, if you are young, you often do self-harm with something other than a knife, probably because you do not have much knowledge about self-harm.


Self-harm temporarily relieves the initial mental distress.However, since it is only immediately after injuring oneself, even if one wants to stop it, in most cases, it will be repeated many times due to new mental distress and become addictive.If you cut it many times, the feeling of that part will be paralyzed and you will become accustomed to seeing blood, so addiction will progress further.Also, when it comes to summer clothes, the wrists stand out, so arm cuts are more common than wrist cuts.

In generalrazor,cutter knifeI often use sharp blades.Not only do you cut self-harm, but you can also hit yourself.In addition, a hair dryer may be used for burning.また、激しい痛みを求める場合にはAlso, if you want severe painscissors,KnifeIn some cases, a blade with a jagged edge is used.切る時はただ切りたいという衝動に駆られるだけで切ることが多いが、後で傷跡やWhen cutting, it is often just driven by the urge to cut, but later scars andkeloidSometimes I feel ugly when I see it and despise myself.

Relationships often become unstable.Social withdrawalHowever, it is often temporary because we basically want to contact people.However, interpersonal relationships are often still unstable.If this condition continues, the ability to examine reality will be weakened overall.

Although it is extremely rare for self-harm to result in death,静脈Even a cut can cause a considerable amount of bleeding, which can be harmful to your health, such as weakening your heart due to extreme anemia.また、精神的に乖離している場合、予定外にAlso, if you are mentally divergent, unplannedarteryIn this case, it may result in death regardless of the person's will.


After a certain amount of time, self-injured people often express their mental stress in words.Since many people were unable to express their own suppressed stress, they often recover depending on the surrounding environment.In fact, if you calm down mentally, self-harm often subsides,ageAt the same time, the number of people who self-harm will decrease.This is thought to be because he gained a way to establish himself through age-appropriate experience.In addition, it may be cured by marriage.However, there are many people who cannot cope with love well and get divorced and self-harm again.

However, there are many cases where the impact is seen throughout the life.より深刻なMore seriousPost-traumatic stress disorder,Dissociative identity disorderThere may be some people.


First of all, in a medical facility, protect it in a safe and privacy environment and do not leave it alone[16]..特に児童青年が自傷行為を行った場合、通常は児童青年病棟に一晩入院させるべきであり、それ以降にフォローアップを行うとNICEは勧告しているNICE recommends that child and adolescents should normally be hospitalized overnight in the child and adolescent ward, especially if they commit self-harm, and follow-up after that.[*1]..非精神科病棟への入院は好ましくなく、やむをえない場合は自傷が繰り返されないよう厳密な対策が求められるHospitalization in a non-psychiatric ward is not desirable, and strict measures are required to prevent repeated self-harm if unavoidable.[16].

Borderline personality disorder,Post-traumatic stress disorderIf you have symptoms of related diseases such as (PTSD), perform psychotherapy / drug therapy according to each guideline.[17].

Assistance policy

It is said that general punishment attitudes should be avoided[18][19]..また、接している者が感情的に混乱するとか、悲しくなるとか、軽蔑してしまうとか、身体の反応としてめまいや興奮、心拍の増加を感じることがあり、それは「正常な反応」であるが、自傷行為を抑制する点では役に立たないため、冷静さを取り戻す必要があるIn addition, the person in contact may feel emotionally confused, sad, despised, or feel dizziness, excitement, or increased heart rate as a physical reaction, which is a "normal reaction". , It is useless in suppressing self-harm, so it is necessary to regain calmness[16][20]..強い反応は、大人を騒がせたい思春期の子どもなど強い反応を期待している行為者にとっては、自傷行為を強化することになるA strong reaction will strengthen self-harm for adolescents who want to make a noise with adults and other actors who expect a strong reaction.[21]..あるいは、自分が他者に拒否されたという体験を追認させ、自傷行為の原因となりえる体験をまたひとつ作り出してしまうOr, let others confirm the experience of being rejected and create another experience that can cause self-injury.[22]..It is then necessary to avoid strong reactions from negative emotions.

You need to be empathetic, but a strong, emotionally positive reaction to help or help can also encourage a stronger self-harm to provoke a protective reaction. is there[23]..つまり、否定的であろうと肯定的であろうと、強い反応は有害であるということであるThat is, a strong reaction, whether negative or positive, is harmful.[24].

It is said that it is important to have good contact with people at that time, not trying to stop anything, but being undecided, compassionate, and not seeking rapid change.[25].

There is no evidence that a self-harm contract has a suppressive effect on self-harm, and the author of the Self-harm Treatment Guide does not recommend it because it is more dangerous.[26]..実際に自傷行為に替わる方法を身につける前の段階での契約では自傷行為を行わないことは難しく、それにもかかわらず「していないと言う」ようになる可能性があるIt's difficult not to do self-harm with a contract before you actually learn how to replace it, and you may nevertheless say you're not.[26].

The Self-harm Treatment Guide contains the Bill of Rights for Self-Injured People, especially for emergency medical professionals.[27][28]..つまり、治療が悪化につながることがあり、それを避けるために、叱責されず思いやりのある治療を受ける権利があり、他に傷がないか強制的に検査することは発見されにくい部位に傷を隠すようになるとか、決めつけをもった態度で接しないようにするための注意であるIn other words, treatment can be exacerbated, and to avoid it, you have the right to receive compassionate treatment without being reprimanded, and forcibly inspecting for other wounds will damage areas that are difficult to find. It is a precaution to avoid hiding or dealing with a prescriptive attitude.[27].

Psychological and social support

Cognitive behavioral therapyIs common.Family therapyEtc. may be used.UK National Institute of Medical Technology(NICE) guidelines suggest 3-12 sessions of psychotherapy[29].

If there is trauma such as PTSD, it refers to cognitive behavioral therapy to solve it.[32].

Drug use policy

For the purpose of reducing self-harm itselfDrug therapyNICE recommends not to go[33]..抗うつ薬や抗不安薬の服用が自傷行為の回数を増加させることもあるし、こうした薬物のTaking antidepressants and antidepressants may increase the frequency of self-injury, and of these drugsOverdoseMay also cause.併存疾患の治療のために薬物を処方する際には、過剰摂取の毒性を検討しConsider the toxicity of overdose when prescribing drugs for the treatment of comorbidities[16][34]For example, in antidepressants, the tricyclic system is highly toxic and should not be prescribed.SSRIIs preferred[34].

Even if it is a single agent, pay attention to the danger of overdose, especiallyBenzodiazepinesAnxiolyticIs recommended to avoid[36].

Epidemiology in Japan

Research on self-harm is extremely late in Japan.本項目でも日本における調査を参考までに多く取り上げているが、これらの調査に対して自傷症患者を取材してきた記者からは「そもそも自傷行為の定義がはっきりしていない」とか「本当に注目しなければならないのは中毒症状になってしまった場合であるのにその辺りが曖昧である」といった疑問が投げかけられており、調査は大まかな指針にはなっても実際には実態を表していない可能性が強いとされているThis item also covers many surveys in Japan for reference, but reporters who have interviewed patients with self-harm for these surveys said, "The definition of self-harm is not clear in the first place." The question has been raised, "What you have to do is when you have a addiction symptom, but the area is ambiguous." It is said that there is a strong possibility that there is no[Source required].

Self-harm in Japan has been known since the 1970s, when cases from Europe and the United States were introduced.In Japan, the number of actual cases tends to increase with the spread of psychoanalysis and psychological terms.奈良教育大学の調査によるとAccording to a survey by Nara University of Education1999It is said that the number has increased sharply from around that time.[Source required].

The contagiousness of self-harm isインターネットThe impact on the above self-harm related sites was also pointed out. According to the evening edition of the Mainichi Shimbun on February 2, at a public junior high school in the Tokyo metropolitan area in 6, several third-year students began to make wrist cuts, but the number has increased sharply since then, and there are less than 2005 third-year students. It is said that the number of people exceeded 3 even if the school was aware of it.Doctors sometimes say that if they are not good at relationships, they may self-harm in order to feel a sense of companionship.

According to the third year survey, responses from 3 second-year high school students,Masako KiharaAs a result of the aggregation and analysis by the assistant professor of Kyoto University Graduate School, 5.3% of boys and 10% of girls had experience of self-harm.また、同調査では「出会い系サイト」は男子3.9%、女子5.8%、「援助交際」は男子1.1%、女子1.5%が経験していると回答しているIn addition, in the same survey, "dating site" was experienced by XNUMX% of boys and XNUMX% of girls, and "enjo kosai" was experienced by XNUMX% of boys and XNUMX% of girls.[42].

Social dimension


Self-harm used to besuicideIt was a symptom that was not understood enough to be regarded as an act.病院でもその行為が理解できない医者が大半であり、病院側も対処に困るケースが大半であったMost of the doctors did not understand the behavior even in hospitals, and in most cases the hospitals had trouble dealing with it.[43].
