Narcissism Test (NPI-16)
The NPI-16 (Narcissistic Personality Inventory, 16-item) is a 16-item self-report questionnaire that measures grandiose narcissistic traits on a spectrum, scored 0–16 (Ames et al., 2006). This page also covers vulnerable narcissism, the DSM-5-TR NPD criteria, and why a high score is not a diagnosis.
Narcissism Test
The word "narcissist" gets thrown around a lot, often to describe anyone who's difficult, self-centered, or hard to deal with. The reality is more detailed. Narcissistic traits exist on a spectrum, and this test, the NPI-16, measures where you fall.
What the NPI-16 measures
Narcissism isn't just arrogance. At its core, it's a set of traits organized around an inflated sense of self-importance, a need for admiration, and a tendency to prioritize one's own interests, sometimes at the expense of others.
But here's what most online content gets wrong: narcissistic traits are on a spectrum everyone shares. Having some narcissistic characteristics is normal and even adaptive, high self-confidence, ambition, and assertiveness often show up in NPI scores. The question is degree and context.
The NPI-16 measures narcissistic traits in the general population. It was designed to measure subclinical narcissism, not Narcissistic Personality Disorder. Those are different things, and the distinction matters.
How to administer the NPI-16
The NPI-16 is a self-report questionnaire with 16 items. Each item presents two statements. For each item, choose the statement that better describes you, even if neither fits perfectly. There's no right answer. Respond as honestly as you can.
NPI-16 scoring and interpretation
Total scores range from 0 to 16; higher scores reflect more grandiose narcissistic traits. The NPI-16 was designed to measure subclinical narcissism in the general population, so it has no clinical cutoff and a high score is not a diagnosis of Narcissistic Personality Disorder.
Population norms from Ames et al. (2006) NPI-16 validation study. Mean score in adults ~7–8.
Psychometric properties
Ames, Rose, and Anderson (2006) created the NPI-16 as a shorter, unidimensional version of the 40-item NPI. Across two studies, Gentile et al. (2013) found that the NPI-16 showed good convergent and discriminant validity and adequate overall reliability. Because it is unidimensional, the NPI-16 yields a total score only; the NPI-13 was proposed as an alternative that also gives three subscale scores.
Limitations
- Not a diagnosis. The NPI-16 measures subclinical traits; NPD requires a clinical evaluation.
- Self-report bias. A core feature of narcissism is limited self-awareness about how one impacts others, which can bias results.
- Grandiose narcissism only. The NPI primarily measures the grandiose presentation and does not capture vulnerable narcissism well.
- Total score only. It does not separate facets such as leadership, exhibitionism, or entitlement.
Narcissistic Traits vs. Narcissistic Personality Disorder
This is the most important distinction you can make after taking this test. The NPI measures traits. NPD is a full clinical evaluation, a different thing entirely.
Narcissistic Traits (NPI measures this)
- Dimensional, everyone has some
- Can be adaptive (confidence, ambition)
- Responsive to feedback and relationships
- Does not require clinical intervention
- Not a diagnosis
Narcissistic Personality Disorder (clinical)
- Pervasive, inflexible pattern causing impairment
- Lacks empathy in clinically significant ways
- Causes distress in relationships and functioning
- Requires professional assessment to diagnose
- Affects 1–5% of population
Grandiose vs. Vulnerable Narcissism
Research distinguishes two narcissistic presentations that can look completely different, and people outside the field often only know the grandiose one.
Grandiose Narcissism
The "classic" presentation. High confidence, dominance, entitlement, low anxiety. Often charming and socially effective. The NPI primarily measures this type.
Vulnerable Narcissism
Hypersensitive, shame-prone, easily threatened. Feels entitled but insecure. Withdrawn or passive-aggressive rather than openly dominant.
DSM-5-TR Narcissistic Personality Disorder Criteria
NPD requires 5 or more of the following, present since early adulthood, and causing significant impairment:
If You're Here Because of Someone Else
Many people search for narcissism tests because they're trying to make sense of a relationship, a parent, partner, or boss who seems to fit the description. A few things worth knowing:
You cannot diagnose someone else with NPD, not from behavior patterns, not from a test they haven't taken, and not even from years of experience with them. That requires a clinical evaluation.
Many behaviors that feel narcissistic can come from trauma, attachment wounds, depression, or ADHD. The label matters less than understanding the pattern and what you need.
If someone's behavior is consistently harmful, the most useful work isn't diagnosing them, it's understanding your own responses, needs, and options with a good therapist.

Frequently Asked Questions
What does a narcissism test measure?
A narcissism test measures traits associated with narcissistic personality, such as grandiosity, entitlement, need for admiration, and lack of empathy. The widely used research scale is the Narcissistic Personality Inventory (NPI), which captures subclinical narcissism on a spectrum. High scores reflect narcissistic tendencies rather than a full clinical evaluation of Narcissistic Personality Disorder (NPD), which requires clinical evaluation.
What is the difference between narcissistic traits and Narcissistic Personality Disorder?
Narcissistic traits exist on a continuum in the general population — many people score moderately on NPI measures without meeting criteria for NPD. A DSM-5-TR diagnosis of NPD requires a pervasive and clinically significant pattern causing distress or functional impairment, assessed by a qualified mental health professional. Subclinical narcissism is common and does not automatically indicate a disorder.
Is there a difference between grandiose and vulnerable narcissism?
Yes. Grandiose narcissism (measured by the NPI) involves overt self-promotion, dominance-seeking, and low anxiety. Vulnerable narcissism involves hypersensitivity to criticism, shame-proneness, and a fragile self-esteem hidden beneath a defensive exterior. Research consistently finds these as two distinct phenotypes, both involving self-centeredness but with very different presentations and emotional profiles.
Can narcissism be treated?
Yes, though treatment is more effective earlier and requires sustained engagement. Schema Therapy targeting defectiveness and entitlement schemas, Transference-Focused Psychotherapy (TFP), and Mentalization-Based Treatment (MBT) have the strongest evidence bases for narcissistic presentations. Progress is possible, particularly when the individual recognizes the impact of their patterns on relationships and is motivated to change.
What causes narcissistic personality development?
Research points to a combination of genetic predisposition and early environmental factors. These include both excessive parental praise (overvaluation) and cold, critical, or neglectful parenting — suggesting multiple developmental pathways. Trauma, particularly childhood emotional invalidation, is implicated in vulnerable narcissism. No single cause has been identified.
How accurate are online narcissism tests?
Validated tools like the NPI-16 or NPI-40 provide reliable self-report data about narcissistic traits when completed honestly. However, a core feature of narcissism is limited self-awareness about how one impacts others, which can bias self-report results. These tools are best used for education and reflection rather than as definitive assessments. A clinical evaluation is needed for any diagnostic consideration.
