Parasuicide refers to deliberate self-harming behavior that resembles a suicide attempt but is typically carried out with low intent to die. The term was coined in the 1960s to describe acts like self-poisoning or self-cutting that bring a person into medical contact without a clear, sustained wish to end their life. Although the word has fallen out of favor in some clinical circles, replaced by broader labels like “deliberate self-harm” or “non-suicidal self-injury,” the phenomenon it describes remains one of the most common psychiatric emergencies worldwide and a persistent challenge for clinicians trying to distinguish who is at serious risk of dying by suicide and who is not.
Where the Term Came From and Why It Is Contested
The psychiatrist Norman Kreitman introduced “parasuicide” in the late 1960s to fill a gap in clinical language. Before that, doctors tended to classify every act of deliberate self-harm as a “suicide attempt,” which lumped together vastly different situations: a person who survived a high-lethality act by chance and a person who took a handful of pills in a moment of crisis with no clear desire to die. Kreitman’s term was meant to capture the second scenario, an act that sits alongside suicide without being the same thing. Research through the following decades generally supported this distinction, finding that parasuicide is usually associated with low suicidal intent even as rising rates made it a growing clinical problem.1PubMed. Hopelessness and low-intent in parasuicide
The controversy is straightforward: calling something “para” (meaning beside or resembling) suicide can sound dismissive, as if the behavior is not serious. Critics argue the label may lead clinicians to underestimate risk. Others counter that collapsing all self-harm into the category of “suicide attempt” inflates risk assessments for people who need a different kind of help. Today, you will encounter the term most often in European research and in older literature. American psychiatry tends to prefer “non-suicidal self-injury” (NSSI) for acts without intent to die and “suicide attempt” for acts with intent, though the boundary between the two is anything but sharp in real clinical practice.
How Common It Is and Who Is Most Affected
Reported annual rates of parasuicide vary enormously depending on how studies define the behavior and which populations they measure, ranging from roughly 3 to 1,100 per 100,000 people. Lifetime prevalence estimates land between about 720 and 5,930 per 100,000. The most consistently identified risk factors are younger age and female gender.2PubMed. A review of the literature on the epidemiology of parasuicide in the general population Those wide ranges reflect real differences across countries, time periods, and study methods, but the pattern of younger women being disproportionately affected holds up across most datasets.
Gender differences become more nuanced when you look at intent. A cross-national study found that serious suicide attempts were rated more frequently in men, while women were more often categorized in the “suicidal gesture” and “suicide parasuicide” groups, where intent to die was lower.3PubMed Central. A cross-national study on gender differences in suicide intent This does not mean women’s self-harm is less dangerous. It means the typical presentation differs: women engage in parasuicidal behavior more often, while men who do self-harm tend to use more lethal methods, which partly explains the long-standing gap between female rates of self-harm (higher) and male rates of completed suicide (higher).
Age of onset matters too. Research on adolescent outpatients found that starting self-harm at a younger age and continuing it over a longer period were both significantly associated with more frequent episodes of self-injury and a greater risk of making a first suicide attempt.4PubMed Central. Is age of self-harm onset associated with increased frequency of non-suicidal self-injury and suicide attempts in adolescent outpatients? In other words, early-onset parasuicide is not something people simply outgrow. The longer the behavior persists, the more it escalates.
What Drives Parasuicidal Behavior
There is no single cause. Parasuicide sits at the intersection of emotional pain, limited coping skills, psychiatric illness, and life circumstances. But a few factors stand out in the research as especially important.
Childhood maltreatment is one of the strongest and most replicated predictors. The severity of childhood abuse or neglect is positively linked to how frequently someone engages in self-harm, and the behavior may serve as a way to escape trauma-related symptoms like intrusive memories or dissociation.5PubMed Central. The relationship between childhood maltreatment and self-harm: the mediating roles of alexithymia, dissociation, internalizing and posttraumatic symptoms One study found that compared to a low-risk reference group, people whose profiles were dominated by childhood maltreatment had more than six times the odds of engaging in non-suicidal self-injury.6PubMed Central. Distinct profiles of childhood maltreatment and recent stress in relation to non-suicidal self-injury: the roles of self-criticism and self-compassion
Difficulty regulating emotions is the psychological thread that runs through most explanations of why people harm themselves. A systematic review and meta-analysis found that among the various dimensions of emotion dysregulation, having limited access to emotion regulation strategies showed the strongest link to self-injury, with a medium-to-large effect size. Purely cognitive aspects of emotion regulation, like the ability to reappraise a situation or stop ruminating, showed weaker associations.7PubMed Central. Emotion Dysregulation and Non-Suicidal Self-Injury: A Systematic Review and Meta-Analysis The practical takeaway from this finding is that people who self-harm often are not lacking insight into their emotions. They know they feel terrible. What they lack is a repertoire of strategies to do something about it other than hurt themselves.
The Role of Psychiatric Illness
Parasuicide rarely occurs in a vacuum. Most people who engage in it have at least one diagnosable psychiatric condition, and the overlap with certain disorders is striking. Borderline personality disorder (BPD) is the condition most tightly linked to repeated self-harm. In one comparative study, about 60% of patients with BPD had attempted suicide at least once in their lifetime, compared to 30% of those with bipolar disorder and 16% of those with major depression alone. When BPD and bipolar disorder co-occurred, lifetime suicide attempt rates exceeded 90%.8PubMed Central. Borderline Personality Disorder With Depression Confers Significant Risk of Suicidal Behavior in Mood Disorder Patients-A Comparative Study
Notably, the severity of borderline and other dramatic-erratic personality traits appears to predict past suicidal behavior better than depressive symptoms do.9Journal of Affective Disorders. Suicidal behavior in patients with major depression and comorbid personality disorders This is counterintuitive for many people who assume depression is the main driver of self-harm. Depression is certainly a risk factor, but the impulsivity, emotional instability, and interpersonal chaos characteristic of BPD create a more immediate and repeated pathway to parasuicidal acts.
What Happens in the Brain
The endogenous opioid system, the body’s own pain-relief and mood-regulation machinery, appears to be altered in people who engage in self-harm. Research has found that people with a history of non-suicidal self-injury have significantly lower baseline levels of certain endogenous opioids, including beta-endorphin and met-enkephalin, in their cerebrospinal fluid compared to people who do not self-harm.10PubMed Central. Nonsuicidal Self-Injurious Behavior, Endogenous Opioids and Monoamine Neurotransmitters The leading theory is that this chronic opioid deficit creates a state of emotional distress, and that the physical pain of self-injury triggers a release of endogenous opioids that temporarily relieves that distress.11PubMed. Endogenous opioids and nonsuicidal self-injury: a mechanism of affect regulation
Preliminary brain-imaging work is beginning to add anatomical detail. A PET study of people with BPD and self-harming behavior found that opioid receptor availability was about 5% lower in key limbic areas, including the amygdala, compared to healthy controls.12International Journal of Neuropsychopharmacology. 522. TARGETING OPIOID NEUROTRANSMISSION IN BORDERLINE PERSONALITY DISORDER WITH SELF-HARMING BEHAVIOR: PRELIMINARY FINDINGS OF A [11C]NOP-1A POSITRON EMISSION TOMOGRAPHY STUDY That is a small study and a small difference, but it points toward a biological substrate: the parts of the brain that process emotional pain and fear may be running with less opioid signaling than usual in people who self-harm, potentially contributing to their dampened pain sensitivity during episodes.
Genetic and Familial Risk
Self-harm runs in families, and not just because family members share environments. Genetic analysis has estimated that common genetic variants account for roughly 10 to 11% of the liability for both self-harm behavior and self-harm ideation, a heritable component that is partially independent of the psychiatric disorders that often accompany self-harm.13PubMed Central. Genetic aetiology of self-harm ideation and behaviour Twin studies have pushed heritability estimates higher, particularly for women, with one large study estimating heritability of self-harm thoughts at about 74% for women and 45% for men.14PubMed Central. Genetic and environmental contributions to self-reported thoughts of self-harm and suicide
The intergenerational picture is complicated by the fact that children of parents who self-harm are exposed to both shared genes and a specific family environment. An offspring-of-siblings study tried to tease these apart and found that about 29% of the association between maternal suicidal behavior and offspring suicidal behavior was due to environmental factors specific to being exposed to a parent’s self-harm, with the rest attributable to shared genetic factors.15Translational Psychiatry. The intergenerational transmission of suicidal behavior: an offspring of siblings study In plain terms, genes matter, but growing up in a household where self-harm occurs adds its own independent risk.
The Link to Later Suicide
This is the question that haunts every clinician who sees a patient after an episode of parasuicide: how seriously should they take it? The answer from long-term data is very seriously. A cohort study that tracked over 1,700 patients for 22 years after an episode of parasuicide found that 8% of them eventually died by suicide. The rate was considerably higher for men (12%) than women (5%). Most of the suicides happened in the first few years after the initial episode, but the risk remained elevated above the general population throughout the entire follow-up period.16PubMed Central. Suicide rate 22 years after parasuicide: cohort study
An 8% suicide rate over two decades may sound modest in percentage terms, but it is dramatically higher than the general population rate and makes a prior episode of parasuicide one of the single strongest predictors of eventual death by suicide. The clinical implication is clear: parasuicide should never be written off as “just attention-seeking.” Even when intent appears low, the behavior signals a level of distress and a pattern of coping that carries real long-term danger.
Why Assessment Is So Difficult
Given those stakes, you would hope there were reliable tools for sorting out who is at highest risk after an episode of self-harm. There are not. A systematic review that evaluated 15 different instruments designed to assess suicide risk found that none demonstrated sufficient diagnostic accuracy.17PubMed Central. Instruments for the assessment of suicide risk: A systematic review evaluating the certainty of the evidence The problem is fundamental: suicidal behavior is rare enough in absolute terms, even among high-risk groups, that any screening tool generates large numbers of false positives (flagging people who will not go on to die) or false negatives (missing people who will). Clinicians still rely heavily on clinical judgment, detailed history-taking, and familiarity with the specific patient, which is why continuity of care matters so much for this population.
A cross-cultural study also found that levels of suicidal intent among parasuicide patients across multiple European regions were surprisingly similar, with only small and clinically insignificant differences between regions, cultures, and genders.18Suicide and Life-Threatening Behavior. A Cross‐Cultural Study of Suicide Intent in Parasuicide Patients This suggests that the internal experience of parasuicide is fairly consistent across settings, which is useful for clinicians: what we know about the behavior from one population largely applies elsewhere.
Treatment Approaches
Treatment for parasuicide generally targets the underlying emotional and psychiatric problems rather than the self-harm directly, because the self-harm is a symptom of distress, not the root cause. The evidence base is stronger for psychotherapy than for medication, though both have been studied.
Dialectical behavior therapy (DBT) is the best-studied psychotherapeutic approach. Originally developed for borderline personality disorder, DBT teaches specific skills for tolerating distress, regulating emotions, and managing interpersonal crises. Reviews of outpatient DBT for adolescents who deliberately self-harm have generally found decreases in self-harm with and without suicidal intent, fewer hospitalizations, reduced depression, and improved quality of life.19PubMed Central. Outpatient Dialectical Behavior Therapy for Adolescents Engaged in Deliberate Self-Harm: Conceptual and Methodological Considerations The emphasis on building a concrete toolkit of alternative coping strategies aligns well with the research finding that limited access to regulation strategies, rather than poor cognitive insight, is most strongly linked to self-injury.
The pharmacological picture is less encouraging. A Cochrane review of drug treatments for self-harm in adults found only uncertain evidence for most medication classes. Newer-generation antidepressants did not clearly reduce repeated self-harm compared to placebo, and mood stabilizers showed no significant benefit either. One small trial of antipsychotics showed a lower rate of self-harm repetition (about 21% versus 75% on placebo), but the evidence was low-certainty and based on only 30 participants.20PubMed Central. Pharmacological interventions for self‐harm in adults A broader meta-analysis of psychotropic medications and suicidal/self-injurious behavior found that on average, medications produced only about an 8% reduction in the frequency of such behaviors. Only antipsychotics as a class, and two specific drugs (citalopram and ketamine), produced larger-than-average treatment effects. Stimulants and typical antipsychotics may actually worsen outcomes.21PubMed Central. Efficacy of psychotropic medications on suicide and self-injury: a meta-analysis of randomized controlled trials
The honest summary is that no medication reliably prevents self-harm on its own. Medications prescribed for the underlying conditions, such as antidepressants for depression or mood stabilizers for bipolar disorder, may indirectly help by improving the psychiatric illness driving the behavior, but treating self-harm itself pharmacologically remains an area with far more questions than answers.
Social Contagion and Peer Influence
Self-harm does not spread like a cold, but it does show patterns of social transmission, particularly among adolescents. Young people are especially susceptible to peer influence, and recent evidence supports social contagion in suicidal behavior alongside other harmful behaviors like bullying and violence.22PubMed Central. Social contagion, violence, and suicide among adolescents
A community study of adolescents who self-harmed found that about 44% reported having friends who also self-harm. Having friends who self-harmed was associated with roughly twice the odds of lifetime suicidality. Social media adds a layer of complexity: adolescents who had posted about their own self-harm online had about three times the odds of lifetime suicidality, though merely seeing self-harm content posted by others was not associated with increased risk.23PubMed Central. Relationship of Social and Behavioral Characteristics to Suicidality in Community Adolescents With Self-Harm: Considering Contagion and Connection on Social Media That distinction matters for parents and educators. Passive exposure to self-harm content online does not appear to be the primary driver. The stronger signal comes from active engagement: having close friends who self-harm, posting about one’s own behavior, and being bullied at school.
Emergency Departments and the Care Gap
Most people who engage in parasuicide first encounter the healthcare system in an emergency department, and the experience is often poor for both patients and staff. ED staff describe the environment as fundamentally ill-suited to meeting mental health needs, citing the chaos, the lack of privacy, and the pressure to move patients through quickly. Nonetheless, frontline workers have identified strategies that help: adapting the physical environment to be calmer and safer, improving processes for accessing mental health consultation, supporting the staff who provide direct care, and connecting patients to community mental health resources before discharge.24PubMed Central. Strategies to Care for Patients Being Treated in the Emergency Department After Self-harm: Perspectives of Frontline Staff
Communication inside the ED also matters. A network-modeling study in an Australian hospital found that psychiatric liaison nurses served as critical hubs for information flow when patients presented with risk of suicide or self-harm. Removing those nurses from the communication network significantly degraded the efficiency of the entire system, suggesting that while the liaison role is valuable, over-reliance on a single point of contact creates a vulnerability. When that person is unavailable, important clinical information can get lost between teams.25PubMed Central.

Digital Tools and Safety Planning
The gap between episodes of care, the days and weeks after an ED visit or between therapy appointments, is when many people are most vulnerable. Digital mental health interventions are increasingly being developed to fill that gap for young people who self-harm. A review of apps designed for adolescents and young adults with self-injurious thoughts and behaviors found that safety planning was the most common feature, present in over half the apps reviewed. Nearly all included customizable emergency contacts, about a third offered lists of coping strategies, and roughly one in five had self-tracking tools for things like mood and urge intensity.26PubMed Central. Digital Interventions for Adolescents and Young Adults Experiencing Self-Injurious Thoughts and Behaviors
Safety planning itself is a structured exercise where you work with a clinician to identify your personal warning signs, list coping strategies you can use on your own, name people you can contact for distraction or support, and include crisis line numbers and instructions for making your environment safer. Having that plan on your phone, accessible at 2 a.m. when a crisis hits, is a practical bridge between clinical appointments. These tools are not substitutes for therapy, but the evidence on safety planning as a brief intervention is growing, and the digital format makes it accessible in the moments when people actually need it.
The broader landscape of parasuicide research is marked by a tension between how common the behavior is and how little certainty exists about the best way to treat it. Psychotherapy works better than medication for reducing self-harm directly, but access to specialized therapies like DBT remains limited in many areas. Pharmacology offers only modest and uncertain effects on self-harm itself, even when medications effectively treat the underlying psychiatric condition. And screening tools, despite decades of development, still cannot reliably predict who will go on to attempt suicide. The clinical reality for now is that the strongest protection comes from attentive human relationships: a therapist who knows the patient’s history, a family member who recognizes warning signs, or even a well-designed app that prompts someone to call a friend before acting on an urge.
