Narcissism: trait vs personality disorder, grandiose and vulnerable forms, common myths and what helps

“Narcissist” has become an everyday word for anyone self-centred or rude, but in psychology it has three layers. The first is narcissism as a trait. The APA Dictionary of Psychology defines narcissism as “excessive self-love or egocentrism”, and in psychoanalytic theory as taking one’s own ego or body as the object of love (APA, 2023a). The second is the psychiatric diagnosis, narcissistic personality disorder (NPD). The same dictionary summarises it as a personality disorder marked by a long-standing pattern of grandiose self-importance and exaggerated talents and achievements, fantasies of unlimited sex, power, brilliance or beauty, an exhibitionistic need for attention and admiration, either cool indifference or rage, humiliation or emptiness in response to criticism, indifference or defeat, and interpersonal disturbances such as feeling entitled to special favours, taking advantage of others and being unable to empathise, and notes that it is included in DSM-5-TR (APA, 2023b). This guide does not reproduce the DSM criteria list. A diagnosis is made by a clinician in an interview, not by counting how many items on a list seem to fit.

Third, the World Health Organization’s ICD-11 has no category called “narcissistic personality disorder” at all. ICD-11 uses a single diagnosis of personality disorder, rated as mild, moderate or severe, with prominent trait domains added (negative affectivity, detachment, dissociality, disinhibition, anankastia and a borderline pattern). Its essential requirements are problems in functioning of aspects of the self, such as identity, self-worth and accuracy of self-view, or in interpersonal functioning, persisting over an extended period, “e.g. lasting 2 years or more”, showing across a range of situations, and associated with substantial distress or significant impairment. On the CDDR’s descriptions, the domain closest to narcissism is dissociality, whose core feature is disregard for the rights and feelings of others, encompassing both self-centredness and lack of empathy; self-centredness shows as a sense of entitlement, expecting others’ admiration, attention-seeking to stay the centre of focus, and anger or denigrating others when the expected admiration is not granted (WHO, 2024).

The research picture that ties the three together is a spectrum. The narcissism spectrum model reflects extensive evidence of continuity between normal and abnormal personality expression and tries to settle problems that have “plagued narcissism scholarship for more than a century”: what the key features of narcissism are and how they are organised (Krizan & Herlache, 2018). So being high in narcissistic traits and having narcissistic personality disorder are different statements, and neither is settled by a label given to someone online. mind.io does not offer a narcissism test. Research scales exist, but this guide prints no items or cut-offs and does not judge any particular person to be “a narcissist”. It sets out the three meanings of the word, the two faces called grandiose and vulnerable, how narcissism differs from healthy confidence and ordinary selfishness, how common it is and how it changes, why these relationships are hard, and what helps when you are in one or recognise it in yourself.

The distinction that matters most in research is between grandiose and vulnerable narcissism. A review of 35 years of clinical theory found that descriptions of pathological narcissism consistently split into expressions emphasising grandiosity and expressions emphasising vulnerable affects and self-states, and that personality research repeatedly finds two broad factors, grandiosity-exhibitionism and vulnerability-sensitivity-depletion. The DSM criteria for narcissistic personality disorder, however, mostly emphasise overt grandiosity, which the review said had left the diagnosis with poor discriminant validity, modest temporal stability and the lowest prevalence of any personality disorder (Cain et al., 2008).

The two faces look quite different. An Annual Review of Clinical Psychology paper summarised grandiose narcissism as “overtly immodest, self-centered, entitled, domineering” and vulnerable narcissism as “self-centered, distrustful, neurotic, introverted”, and argued that failing to distinguish them had made the literature less coherent (Miller et al., 2017). A study that factor-analysed three narcissism scales in 858 people and then compared the two dimensions’ correlates in 238 undergraduates found that both go with treating others antagonistically, but that their networks of relations with personality, interpersonal behaviour and psychopathology were otherwise unrelated (Miller et al., 2011). A meta-analysis of gender differences described vulnerable narcissism as “marked by low self-esteem, neuroticism, and introversion” (Grijalva et al., 2015). In other words, the vulnerable face can look less like a confident person than like an anxious one with low self-esteem.

In Korea, the Pathological Narcissism Inventory, which measures both factors, has been translated and validated. In 327 university students, grandiosity correlated positively with positive affect and not significantly with depression or negative affect, whereas vulnerability correlated positively with depression and negative affect and negatively with positive affect. Both correlated positively with trait anger, and the relatively grandiose and relatively vulnerable groups did not differ on trait anger (Yang & Kwon, 2016). The two faces are not mutually exclusive types, though. A recent review concluded that strong support exists for the co-occurrence of the two presentations among people with high levels of grandiose narcissism (Weinberg & Ronningstam, 2022). Rather than sorting people into one or the other, it is closer to the research to notice which face comes forward in a given person at a given time.

Narcissism is not self-esteem turned up too high. Psychologists and popular culture alike have called it “an exaggerated form of high self-esteem” or “inflated self-esteem”, but a developmental review gathered research showing that narcissism differs markedly from self-esteem in its phenotype, its consequences, its development and its origins. The review defines narcissism as “a personality trait characterized by a sense of superiority and a desire for respect and admiration from others”, and proposes that interventions could raise self-esteem while curtailing narcissism at the same time, from an early age (Brummelman et al., 2016). Research on love separates the two as well. Across five studies, narcissism was associated mainly with a game-playing love style, which stemmed from a need for power and autonomy and was linked to perceiving more alternatives and feeling less commitment; self-esteem, by contrast, was negatively linked to manic love and positively to passionate love (Campbell et al., 2002). Healthy confidence survives without putting others down or demanding admiration. The signs to look at when your self-esteem feels low are in the guide to signs of low self-esteem, and the difference between self-esteem and self-compassion in the self-compassion vs self-esteem guide.

It also differs from ordinary selfishness. Everyone looks after their own interests at times, and nobody sees other people’s needs well when they are exhausted. ICD-11 states that its personality trait domains are “continuous with normal personality characteristics in individuals who do not have personality disorder or personality difficulty” and are not diagnostic categories. What differs is degree, persistence and range. Personality disorder is diagnosed only when problems in self or interpersonal functioning have persisted over an extended period (for example 2 years or more), are not limited to specific relationships or roles, and come with substantial distress or impairment. Below that sits a separate level, “personality difficulty”, for pronounced personality characteristics that show only intermittently, such as under stress, or at low intensity, with problems in functioning that are not severe enough to disrupt social, occupational and interpersonal life noticeably (WHO, 2024).

Culture matters too. ICD-11 notes that traits of self-involvement that are accepted or positively valued in individualistic cultures may be considered narcissistic in collectivist cultures, and that a personality disorder diagnosis must take the person’s cultural background into account (WHO, 2024). In a culture that expects modesty, as Korea often does, assertive self-presentation can be called “narcissistic” rather easily. So the question to ask before using the word is not “is this person confident?” but “do they disregard other people’s rights and feelings over a long time and across situations, and is that actually harming them or the people around them?” The word “psychopath” works the same way: it is an everyday label, not a diagnosis. What it means and how it differs from antisocial personality disorder are set out in the psychopath and sociopath guide.

How common narcissistic personality disorder is depends heavily on how it is measured. In a US national survey that interviewed 34,653 adults face to face in 2004 and 2005, the lifetime prevalence on DSM-IV criteria was 6.2%, 7.7% in men and 4.8% in women. It was more prevalent among younger adults and among people who were separated, divorced, widowed or never married, co-occurrence with substance use, mood and anxiety disorders and other personality disorders was high, and the authors concluded that the disorder may not be as stable as DSM-IV described (Stinson et al., 2008). By contrast, a systematic review of 7 studies using structured or semi-structured interviews published between 1980 and August 2008 put the mean prevalence in adult non-clinical samples at 1.06%, with a range of 0% to 6.2%, and called it low overall (Dhawan et al., 2010). Within what we could find, Korea has no population estimate. The items of the K-CIDI used in the 2021 National Mental Health Survey of adults cover nicotine and alcohol use disorders, anxiety disorders, depressive disorders, obsessive-compulsive disorder and post-traumatic stress disorder, and suicidality, with no personality disorder module (NCMH, n.d.).

There is a gender difference, but it is small. A meta-analysis pooling 355 studies and 470,846 people found men scoring higher than women in narcissism with an effect size of d = 0.26, driven mainly by the exploitative/entitlement and leadership/authority facets. On vulnerable narcissism, men and women did not differ (42 studies, d = −0.04). The authors warned against overapplying small effect sizes to perpetuate gender stereotypes (Grijalva et al., 2015).

The claim that younger generations are more narcissistic has mixed support. A meta-analysis of US college students’ NPI scores (107 studies, 49,818 students) reported an increase of d = 0.37 from 1982 to 2008 once campus was controlled for (Twenge & Foster, 2010). But a study comparing three cohorts, 1,166 students in the 1990s, 33,647 in the 2000s and 25,412 in the 2010s, was the first to test whether the items worked the same way across generations; after accounting for the items that did not, it found a small decline in overall narcissism from the 1990s to the 2010s (d = −0.27), with the leadership, vanity and entitlement facets all decreasing (Wetzel et al., 2017). Both are US college samples.

With age it generally declines. A meta-analysis of longitudinal data from 51 samples and 37,247 participants found that narcissism typically decreases from age 8 to 77: d = −0.28 for agentic narcissism, d = −0.41 for antagonistic narcissism and d = −0.55 for neurotic narcissism, while rank-order stability over an average gap of 11.42 years was high at .73, .68 and .60 respectively. Averages fall, that is, but people’s relative positions are fairly well kept. The data were mostly Western and White samples (Orth et al., 2024). A study that followed 747 people born between 1923 and 1969 from age 13 to 77 likewise found that the more maladaptive forms, such as hypersensitivity and wilfulness, declined across life while autonomy increased (Chopik & Grimm, 2019).

It starts out attractive. In a study in which 73 psychology freshmen judged one another on brief self-introductions (2,628 pairs), higher narcissism went with greater popularity at first sight, and the aspects that are most harmful in the long run, exploitativeness and entitlement, were the most attractive at zero acquaintance (Back et al., 2010). In discussion groups of 4 to 6 people who met 7 times, trait self-enhancers made positive impressions at the first meeting, seeming agreeable, well adjusted and competent, but after 7 weeks they were rated negatively and their self-evaluations diverged from the evaluations their peers gave them (Paulhus, 1998). A study in which 311 people met weekly in small groups for 3 weeks videotaped the process: over time, people high in narcissism became less popular, as the dominant, expressive behaviour tied to the admiration-seeking facet lost its effect and the arrogant, aggressive behaviour and the impression of untrustworthiness tied to the rivalry facet grew (Leckelt et al., 2015). This is part of why the relationship gets harder the closer it gets.

Commitment tends to be lower. In two studies of people in ongoing romantic relationships, narcissism was negatively related to commitment, and the link was explained mainly by perceiving alternatives to the current relationship and attending to alternative partners (Campbell & Foster, 2002). The game-playing love style of people high in narcissism was confirmed by their past and current partners (Campbell et al., 2002). After marriage it shows slowly. In a community sample of 146 newlywed couples assessed 6 times over the first 4 years of marriage, wives’ total narcissism and entitlement/exploitativeness scores predicted steeper declines in marital satisfaction and steeper increases in marital problems, while husbands’ narcissism generally had few effects on their own or their wives’ marital quality; the authors noted that the effects of personality may take time to show (Lavner et al., 2016). These are associations in group averages; they do not say how any one person’s relationship will go.

There is also a link with aggression. In a meta-analysis of 437 studies and 123,043 participants, narcissism was related to aggression (r = .26) and violence (r = .23); the link was stronger under provocation (r = .29) than without it (r = .12) but significant even without provocation, and it held for both “normal” and “pathological” narcissism, for grandiose and vulnerable narcissism, and in individualistic and collectivistic countries. The authors’ reading was that people high in narcissism have “thin skins” and are prone to aggression when provoked (Kjærvik & Bushman, 2021). In 328 people from the general population (176 women), vulnerable narcissism predicted physical or sexual abuse perpetration and grandiose narcissism predicted psychological abuse perpetration in men, while in women only vulnerable narcissism predicted either (Green et al., 2020). In a preregistered study of how acceptable people found gaslighting tactics, all of the Dark Tetrad traits, narcissism among them, went with more acceptance, with the limitation that it measured acceptance, not perpetration (March et al., 2023). All of these are correlations, and r = .26 is a modest size: most people with high narcissism scores are not violent, and none of this is grounds for declaring a particular person dangerous. But if you are afraid of the other person’s anger, or there are threats or violence, safety comes first whatever the trait is called. In immediate danger, call your local emergency number.

If manipulation that shakes your sense of reality keeps repeating, see the gaslighting guide; the common conflicts that come from distance are in the guide on talking with an avoidant partner.

To be honest, within what we could find there is no self-help method with tested effects for the partners or family of a highly narcissistic person. What follows is general advice from the clinical literature and counselling practice, not a method proven in research. First, name behaviours, not the person. “You are a narcissist” is neither a diagnosis nor an opening for conversation; “when you cut me off and turn it to your story, I feel dismissed” points at something that can change. Second, avoid power struggles. Clinicians who reviewed treatments of patients with narcissistic personality disorder listed, among the common mistakes therapists make, engaging in a power struggle with the patient, overindulging the patient’s grandiosity and directly challenging it (Weinberg & Ronningstam, 2020). If that is true for trained therapists, an argument about who is right is unlikely to go well for a family member either. Third, decide your limits in advance: which words or actions mean you stop the conversation and leave the room, and then do exactly that. It is not a way to change the other person; it concentrates on what you can control on your side.

Keep an outside perspective. In group studies in which strangers spent a few weeks together, ratings of people high in narcissism worsened over time, and arrogant, aggressive behaviour and an impression of untrustworthiness played a growing part (Leckelt et al., 2015; Paulhus, 1998). Those studies did not follow close relationships directly, but being inside one for long can make it hard to trust your own judgement, so tell someone you trust exactly what is happening and ask how it looks to them. Writing down what happened and when gives you something to check your memory against later. You can seek counselling even when you are not sure whether the relationship counts as abuse. In Korea, the Women’s Emergency Line 1366 offers anyone, men and women alike, who is struggling with domestic or dating violence initial counselling 24 hours a day (MOGEF, n.d.), and the mental health crisis line 1577-0199 (24 hours) connects you to the nearest community mental health welfare centre (MOHW, 2025). Elsewhere, your local domestic abuse helpline and your family doctor are the first ports of call. In immediate danger, call your local emergency number.

If the relationship feels like too much to carry, or you have thoughts of hurting yourself, reach out first to a crisis line: call or text 988 in the US and Canada, call Samaritans on 116 123 in the UK and Ireland, or find a line at findahelpline.com elsewhere. If you are in immediate danger, contact your local emergency services.

Some people feel this about a parent. Research on how a parent’s narcissistic traits affect children is still thin, and within what we could find there was no representative study worth citing. Still, if as an adult you always feel small around a parent, exhaust yourself seeking their approval, or feel guilty for keeping your distance, that in itself is a topic worth taking to counselling. Whoever the other person is, if your sense of self has not recovered after the relationship ends, a psychiatrist or psychotherapist can help. Practising treating yourself kindly again is covered in the self-compassion guide and the guide to building self-esteem, and the attachment style test shows how you draw close and pull away in relationships. Neither is a test that judges the other person; they are tools for looking at yourself.

Being able to worry that this might be you is itself the starting point: it means you can see yourself through other people’s eyes. Check two things first. One is what brought you here: whether you feel empty when admiration dries up, whether rage or humiliation comes first when you are criticised, whether the people close to you keep saying the same thing. The other is whether this is the vulnerable face. Vulnerable narcissism goes with low self-esteem, neuroticism and introversion (Grijalva et al., 2015), and in Korean university data vulnerability rose together with depression and negative affect (Yang & Kwon, 2016). If so, what needs attention right now may be depression, anxiety or self-esteem rather than the question “am I a narcissist?”. The self-esteem test shows how much you value yourself at the moment, and the self-compassion guide whether you drive yourself or treat yourself kindly. In personality research the two faces share an antagonistic way of treating others but diverge on broad traits such as neuroticism and extraversion (Miller et al., 2011; Miller et al., 2017); the Big Five personality test shows those broad traits, but it is not a narcissism test.

It does change, but slowly. In the longitudinal meta-analysis, narcissism declined on average across the life span, and the antagonistic and neurotic aspects declined most (Orth et al., 2024). On treatment, a recent review concluded that longitudinal studies support the view that patients with narcissistic personality disorder can improve, but that such improvement is gradual and slow, and that the several treatments developed for the disorder mostly share clear goals, attention to the treatment frame, attention to relationships and self-esteem, and alliance building (Weinberg & Ronningstam, 2022). Clinicians who reviewed treatments named as principles of effective therapy helping patients identify the goals and direction of therapy, promoting a sense of agency, promoting a shift of focus to the sense of vulnerability, and anticipating difficulty in building and keeping the alliance (Weinberg & Ronningstam, 2020). Know the limits of the evidence too: a team that systematically searched the literature from 1980 to August 2008 found no controlled studies of treatment for narcissistic personality disorder without other co-occurring conditions (Dhawan et al., 2010). The treatments described in the literature are psychotherapies. The disorder co-occurs at high rates with substance use, mood and anxiety disorders (Stinson et al., 2008). So in practice, treatment may begin with a co-occurring problem such as depression or anxiety.

What you can do day to day is small: let the other person finish without turning the conversation to yourself, wait a day before answering criticism rather than firing back, and apologise without a “but” when an apology is due. These are not research-tested methods but general exercises drawn from the treatment principles above. The developmental review proposed that, because self-esteem and narcissism arise from different socialisation experiences, it is possible to raise self-esteem and curtail narcissism at the same time from an early age (Brummelman et al., 2016). Whether the same is possible in adults is outside what that review covered. Ways of building a self-esteem that does not need to put others down are in the guide to building self-esteem. If the emptiness runs deep, or you have thoughts of hurting yourself, reach out first to a crisis line: call or text 988 in the US and Canada, call Samaritans on 116 123 in the UK and Ireland, or find a line at findahelpline.com elsewhere. If you are in immediate danger, contact your local emergency services. With a psychiatrist or psychotherapist, you can start from what hurts right now instead of asking whether you are “a narcissist”.

Q. Is there a narcissist test? A. mind.io does not offer a narcissism test. Research uses scales such as the Narcissistic Personality Inventory (NPI) and the Pathological Narcissism Inventory (PNI), and the PNI has a translated and validated Korean version (Yang & Kwon, 2016). Those scales are for research, though, and the result of an online “narcissist test” is not a diagnosis. A personality disorder is diagnosed by a clinician, in an interview, by checking whether problems in self and interpersonal functioning have lasted a long time across situations and whether they cause impairment (WHO, 2024). There is certainly no test designed for judging someone else. The attachment style test shows how you draw close and pull away in relationships, the self-esteem test how much you value yourself right now, and the Big Five personality test your broad traits, but none of the three is a narcissism test.

Q. I have heard that narcissists never change. A. That is not what the research says. In a longitudinal meta-analysis of 51 samples, narcissism declined on average from age 8 to 77, with the antagonistic and neurotic aspects declining most. People’s relative positions were fairly stable, though, so someone higher than others tends to stay relatively higher later (Orth et al., 2024). In treatment, a recent review concluded that patients can improve but that improvement is gradual and slow (Weinberg & Ronningstam, 2022). “They never change” does not match the research, and we found no evidence for “my love will change them”. Whether the other person changes depends on their own will and on treatment; what you can do is keep your own limits.

Q. Are men more narcissistic? A. There is an average difference, but it is small. In a meta-analysis of 355 studies men scored higher than women, at d = 0.26, and on vulnerable narcissism there was no difference; the authors warned against overapplying small effects to gender stereotypes (Grijalva et al., 2015). In the US national survey the lifetime prevalence of narcissistic personality disorder was 7.7% in men and 4.8% in women, a difference, but a minority in both (Stinson et al., 2008). There are no grounds for “all men are like that” or “women never are”.

Q. Is today’s generation more narcissistic? A. The evidence conflicts. A meta-analysis of US college data reported an increase of d = 0.37 between 1982 and 2008 (Twenge & Foster, 2010), but an analysis that first tested whether the items meant the same thing across generations found a small decrease from the 1990s to the 2010s (d = −0.27; Wetzel et al., 2017). Within what we could find, no study has tracked generational change with Korean data. Self-display being more visible on social media and people’s personalities changing are different questions.

Q. My partner says I am a narcissist. A. The word has spread in a broad sense, so it easily becomes a label thrown at each other in arguments, and a label settles nothing. A personality disorder is diagnosed by a clinician (WHO, 2024), and having high narcissistic traits and having the disorder are different statements. Still, if you keep hearing the same thing, look for what might be worth hearing in it: concrete behaviours such as cutting the other person off and turning the conversation to yourself, or answering criticism with anger. If, on the other hand, neuroticism and low self-esteem lie underneath, as in the vulnerable face, that is what needs attention (Grijalva et al., 2015). If arguments always end in who is the problem, counselling together or separately is worth trying.

Q. My parent seems narcissistic. Should I cut contact? A. Nobody can make that decision for you, and this guide neither tells you to nor tells you not to. Research on how a parent’s narcissistic traits affect adult children is still thin, and within what we could find there was no representative study worth citing. What you can do is set the terms of distance and contact yourself, redirect the energy you spent trying to change the parent into your own life, and take the guilt to counselling if it is too heavy. When your sense of self wavers, see the self-compassion guide, and when loneliness lingers the loneliness guide. If things feel like too much right now, or you have thoughts of hurting yourself, reach out to a crisis line: call or text 988 in the US and Canada, call Samaritans on 116 123 in the UK and Ireland, or find a line at findahelpline.com elsewhere. If you are in immediate danger, contact your local emergency services.
