Though self-harm is not a mental health disorder, it is often a symptom of other conditions, which makes understanding self-harm facts and statistics essential.

Self-harm involves a person damaging their body by cutting, burning, scratching or practicing any other behavior that results in pain or injury. Different motivators can encourage people toward self-harm, such as feeling overwhelmed or numb. Though self-harm is not a mental health disorder, it is a common symptom of many psychological conditions. Self-harm statistics and facts show the widespread trend of self-harm throughout the United States.

Article at a Glance:  

  • Self-harming behaviors include cutting, burning, and scratching oneself.  
  • The rates of self-harming behaviors are likely much higher than the statistics actually reported.  
  • Teens have the highest rates of self-harming behaviors.  
  • Self-harming behaviors are often co-occurring with eating disorders and substance abuse.  
  • Self-harm is not a mental health condition in itself, but treatment is available if self-harm is connected to drug and alcohol abuse. 

Self-Injury Prevalence

Even though self-harm has been studied extensively for over a decade, findings are never entirely accurate because of the stigma and shame that still surrounds self-injury. The actual rates are likely quite higher than those currently reported.

One analysis of self-injury across more than 40 countries found that:

  • About 17% of all people will self-harm during their lifetime
  • The average age of the first incident of self-harm is 13
  • 45% of people use cutting as their method of self-injury
  • About 50% of people seek help for their self-harm but only from friends instead of professionals

Not only is self-harm prevalent, but rates are increasing. According to emergency room trends, there’s been a 50% increase in reported self-injury among young females since 2009.

Who Self-Harms?

While anyone can practice self-harm, rates tend to differ among certain populations:

  • Adults. Aside from very young children, adults are the least likely group of people to follow through with self-injury. Only about 5% of adults have self-injured in their lifetime.
  • Teens. Adolescents have the highest rate of self-injurious behaviors, with about 17% admitting to self-injury at least once in their life.
  • College Students. Studies find that about 15% of college students report engaging in self-harm.
  • Women vs. Men. While women are more likely to self-harm, males may represent at least 35% of total self-injury cases. Men are more likely to underreport self-injury and have other people hurt them than women.
  • Sexual MinoritiesGay and bisexual people are at a high risk of self-injury. Nearly half of all bisexual females engage in self-injury.

Age of Onset

As mentioned, the average age of onset for self-injury is 13. This age seems to align with new stressors and expectations at school and home as the child enters their teenage years. Age 13 represents a time of great physical, social and mental change and development. This time is also linked to the emergence of mental health conditions like anxiety and depression, which may further trigger a desire to self-harm.

Self-Harm Risk Factors

There is not just one factor that contributes to self-harm. Instead, there are a variety of biological and environmental issues known to cause self-harm, including:

  • Having friends or family members who self-injure
  • Experiencing stressful life situations like traumatic events, family instability and sexual identity uncertainty
  • Living in social isolation
  • Mental health conditions, like depressionanxiety and personality disorders
  • Drug and alcohol use or addiction

The more of these factors a person has, the higher their risk of self-harm.

Diagnosing Nonsuicidal Self-Injury Disorder (NSSID)

Nonsuicidal self-injury is not a diagnosable mental health condition: yet. Currently, the American Psychiatric Association (APA) lists nonsuicidal self-injury as one of the “Conditions for Further Study” in the most recent Diagnostic and Statistical Manual of Mental Disorders (DSM-5). This designation implies the group may include the condition in future versions of the text.

Nonsuicidal self-injury involves symptoms like:

  • Engaging in self-harm on five or more days over the last year
  • Self-injuring to find relief from an unwanted feeling, solve a relationship conflict or create a desired feeling
  • Self-harm involves unwanted feeling like depression, anxiety or anger, an intense focus on completing the behavior and frequent thoughts of self-injury

Since self-injury is not currently an official mental health diagnosis, a medical or mental health professional will ask the person questions about the behavior and the purpose of the behavior to assess the situation.

Rates of Self-Harm and Co-Occurring Conditions

Self-harm often co-occurs with mental health disorders. Historically, self-harm was thought to be directly connected to borderline personality disorder. Now, it’s understood that the behavior can be associated with many conditions, like:

One study found that of people who self-injure:

  • 20% have personality disorders
  • 13.5% have adjustment disorders
  • 11% have mood disorders, like depression or bipolar disorder

Addition research shows that about 55% of people who self-harm have eating disorders.

Although the conditions may overlap, nonsuicidal self-injury is often not linked to:

Self-Harm and Suicide

Although an act of self-harm is different from a suicide attempt, there is a strong association between self-injury and suicide attempts. It seems that as incidents of self-harm increase, the likelihood of suicide attempts also increase.

People who engaged in 20 or more self-harm behaviors are about 3.5 times more likely to attempt suicide compared to those who have fewer self-injury actions.

Self-Harm Prognosis

Establishing a self-harm prognosis is based on:

  • Frequency of self-harm
  • Intensity of self-harm
  • Duration of self-harm
  • Presence of other mental health symptoms or conditions
  • Available professional or social support

The APA reports in the DSM-5 that self-injury tends to peak by the time a person is 29, so the prognosis improves as age increases.

Statistics on Self-Harm Treatment

Since self-harm is not a mental health condition of its own, tracking treatment statistics is challenging. What experts do know is that treatment must focus on the factors that trigger self-harm, as well as the self-harm itself.

For example, if your self-harm is connected to substance use, getting help from The Recovery Village could reduce self-harm as you find recovery from alcohol and other drugs. Call today to speak to a representative about available treatment options for self-harm and substance use disorders.
