Narcissistic personality disorder (NPD) is defined in the
DSM-5-TR (
1) in terms of a pervasive pattern of grandiosity (in fantasy or behavior), need for admiration, and lack of empathy, with onset by early adulthood and present in a variety of contexts. The disorder is found in 1%–2% of the general population, 1.3%–20% of the clinical population, and 8.5%–20% of the outpatient private practice population (
2). It is associated with increased risk and persistence of comorbid conditions—mood and anxiety disorders; alcohol and substance use disorders; suicide; and legal, vocational, relational, and marital problems (
3). People diagnosed as having NPD experience elevated distress (
4), cause more pain to others (
5), and have a lower quality of life (
6) than those without the disorder. Pathological narcissism is defined as pervasive and consistent difficulty maintaining realistic self-esteem that, at its extreme, manifests as NPD (
7).
In this article, we review advances in understanding and treatment of NPD during the past decade. We discuss changes in diagnostic approach, various manifestations and mechanisms of the disorder, developmental factors, naturalistic longitudinal course, and treatment strategies.
NPD: Categorical Versus Dimensional Diagnosis
Historically, NPD has been defined in the
DSM, including the
DSM-5, through a list of nine nomothetic criteria that capture grandiose narcissism. Fulfilling five out of nine criteria is a cutoff score for meeting inclusion criteria. This categorical approach makes clear who meets the criteria for the disorder and who does not, and it maintains continuity with the previous literature on the disorder and its treatment. However, this criteria-based definition has been criticized as too narrow (
8); at the same time, the categorical diagnosis of personality has been criticized as well (
9). These concerns have paved the way for development of the dimensional model of diagnosis (
10).
The dimensional model emphasizes four areas of functioning organized into two dimensions each—self (identity, self-direction) and interpersonal relations (empathy, intimacy), as well as two personality traits (grandiosity and attention seeking), which represent antagonism (
Box 1). The dimensional approach has the following strengths: it provides clinically meaningful description of the patient’s individual personality patterns, subjective motivation, and experiences (
11,
12); attends to fluctuations and range of phenotypic presentations; incorporates sense of self-agency (i.e., competence, decision making, motivation, and sense of control [internal and external]); and emphasizes a complex interaction among various capabilities, deficits, motivations, self-regulation, and self-enhancement in coloring expressions of self and interpersonal domains. This approach guides clinicians to assess the disorder and to remain open-minded to the complex and fluctuating manifestations of this disorder. The approach also suggests exploring various aspects of patient functioning, which are likely to be hidden by the patient or not mentioned if the assessment relies exclusively on unguided patient self-report.
Both the
DSM-5 (Section III) (
1) and the
ICD-11 (
13) recommend using a hybrid model of diagnosis, which combines the categorical and dimensional models, because this combination has the strongest predictive validity (
9,
14). The following vignette shows the complex interaction of an other-oriented sense of identity in the context of different experiences of self and others. Fluctuations in self-esteem with significant self-negativity are associated with difficulties tolerating and integrating emotions as well as with ambivalence toward one’s own aspirations and others’ ideal expectations.
Mr. A is a 25-year-old college graduate who worked as an office assistant in a law firm. He was recommended psychotherapy by his supervisor as he had begun smoking cannabis and avoiding exposure and challenges at work. He had been a competent basketball player for his college team. After graduation, he was forced to leave his team and, thus, struggled with emptiness and identity confusion. He felt lost and stuck in life, ashamed of his job, and, perceiving himself as a failure, unable and unmotivated to pursue education toward a law career. His biological father was an industrial worker and a devoted dog owner, whereas his stepfather, who came into his life when he was 5 years old, was a professor in law with international accomplishments. Although he loved his biological father and enjoyed playing with his dogs, Mr. A felt repelled by his father’s lifestyle and lack of ambitions. On the other hand, although the stepfather’s extraordinary recognition and competence intrigued and benefited him, Mr. A felt threatened and diminished by his presence. He was also aware that his stepfather had provided a significantly different lifestyle, with opportunities and security. He felt he put on different faces and facades in different situations to avoid conflicts and expectations, but also to gain approval. He also felt that he did not deserve to pursue a continuing basketball career. Further exploration in psychotherapy revealed Mr. A’s anger and disappointment at both of his fathers, as well as his deep shame thereof. In addition, he struggled with distrust and a lack of reliable support from his mother, whom he felt was critical and demanding, perceiving him as unable to measure up to the changed sociocultural values and economic standards in the new family.
Subtypes of NPD
Complexity in the clinical presentation of NPD has spurred description of different characterological types of the disorder. Are these different manifestations of the disorder or do they constitute different personality types? Since the beginning, the research literature has highlighted the multifaceted nature of pathological narcissism. Early emphasis on the grandiose presentation gave way to recognition of two types of narcissism: grandiose and vulnerable (
15,
16). This categorization remains consistent with the criticism of the construct of grandiose narcissism as being too restrictive (
17). Compared with the general population, people with grandiose narcissism appear as bold and charming, although they are more disagreeable, engage in more social comparison, feel more envy, are more extraverted, more likely to pursue status, and have higher reported self-esteem (
18,
19). People with vulnerable narcissism are more introverted, anxious, and avoidant, but they are disagreeable and less conscientious, and they report more anger, shame, and depression, as well as higher hostility and/or aggression and lower self-esteem, trust, and relationship satisfaction (
18,
19). Both manifestations are characterized by entitlement—a belief that one is deserving of special benefits and attention (
7). The presence of this belief proves important for the differential diagnosis of the vulnerable manifestation from other conditions, such as mood or anxiety disorders. Initially, both presentations were considered separate types of pathological narcissism that occurred among different people. Over time, clinical experience and documented research have proven that these two presentations tend to co-occur.
It appears that when levels of vulnerable or grandiose narcissism are low to moderate, these two dimensions are independent. However, grandiose and vulnerable narcissism tend to co-occur within the same patient when high levels of grandiosity are present (
19). More specifically, people who are grandiose tend to express both grandiose and vulnerable facets, whereas people who are vulnerable tend to present with high vulnerability and low grandiosity (
20).
Vulnerable narcissism is also associated with impaired optimism and future orientation, noticeable in diminished sense of agency and strivings toward personal growth (
21). The distinction between chronic depression in depressive personality disorder and vulnerable narcissism is important because both are often associated with similar qualities (
22). However, entitlement, assertiveness, overvaluing one’s own accomplishments, and aggressive reactions when aspirations fail or remain unrecognized are distinguishing features accompanying self-negativity and depressivity in vulnerable narcissism.
The co-occurrence of grandiose and vulnerable narcissism expresses itself in numerous ways. Some patients alternate between grandiose and vulnerable presentation in different sessions (
23):
When Mr. B started therapy, he described himself in a confident and haughty way. He self-identified as arrogant and very competitive, dreaming of making the “30 under 30 list” with his newly launched start-up company. Two sessions later, he described a paralyzing sense of insecurity, shame, and rejection sensitivity in his romantic relationship. He worried that his partner might break up with him because of his almost invisible hair loss, “a possibility” that he does not make enough money, and a worry that he will run out of jokes to make her laugh.
Other patients display an intermixture of vulnerable and grandiose traits concurrently. This presentation creates a paradoxical coexistence of seemingly contradictory traits and modes of operating and relating:
Ms. C started treatment in the context of pervasive insecurity about social interactions. She described difficulty initiating conversations because of fear of rejection and feelings of shame, combined with a tendency to be easily offended and an expectation to be automatically accepted by others. After a few months of treatment, she described a deep-seated tendency to judge herself and others and to think of others as “incompetent and stupid.” She wanted to feel better than others and frequently fantasized about becoming a world-famous artist, thus “proving to be better than others.”
Interpersonally, many patients with pathological narcissism, including NPD, are capable of a fluid adaptability, guided by impression management. This adaptability creates a chameleon-like clinical presentation accompanied by a theatrical, performative, and disingenuous atmosphere. Subjectively, the patient frantically attempts to mask personal limitations, make a “perfect” impression, and create an “ideal” connection. For some patients, this attempt leads to a haughty, grandiose presentation; for others, paradoxically, a vulnerable one. The latter scenario is more likely to occur when the patient invests in a narrative of helpless, agentless victim, or is afraid of expectations of change. In this way, the patient tries to lower the interviewer’s expectations.
Another form of fluidity has to do with the intrapsychic tendency to shift from one personal narrative to another to protect a sense of specialness and superiority (
24,
25). Similar to kings of the Assyrian Empire, patients re-tell their own history in order to erase failures, disappointments, or embarrassments, and to glorify their sense of specialness. Others are invested in perpetuating the opposite narrative to minimize expectations and, thus, shield themselves from anticipated failure (
26). Paradoxically, dysphoria has a protective effect on self-esteem for patients invested in negative predicaments.
An additional dimension of pathological narcissism is overt versus covert expression. The overt expression corresponds to the prototypical manifestations of grandiose or vulnerable narcissism. However, in some patients these manifestations become suppressed, dissociated, or kept secret (
27). As a result, patients experience their conscious self as bad, weak, inadequate, or shameful. Difficulties with intimacy are prevalent and so is the tendency to rely on interpersonal distancing, to the point of aloofness. This aloofness shields them from disappointments, rejections, and challenges to self-esteem. Clinically, although these patients may present with a wide variety of symptoms, overall, they display a pervasive difficulty maintaining self-esteem. Consequently, they tend to have strong internal reactions to disappointments, rejections, or challenges to self-esteem, which they then tend to dissociate and deny. Sometimes the covert presentation occurs because of a history of being humiliated, shamed, or criticized for overt expression of narcissistic experiences and needs (
27). The overt versus covert dimension is independent of the vulnerability versus grandiose dimension (
11,
28), although unlike the latter, it is relatively invariable over time and across domains. Some patients show a mixture of overt and covert features in different domains (
28).
These characteristics invite clinicians to take an open-minded, longitudinal, and careful approach to assessment, while considering multiple sources of information and paying attention to verbal and nonverbal reactions as well as to their own reactions to the patient.
Developmental Factors in the Etiology of NPD
One way to understand the multiplicity of the mechanisms is through the complexity of the developmental trajectories that lead to the development of pathological narcissism, including NPD. Early clinical observations attributed development of the disorder to single developmental factors, such overvaluation and lack of warmth, overindulgence and lenient discipline, role reversals with parents (parentification), molding the child according to parental wishes, childhood abuse, cold and rejecting parenting, and unavailable parents (
53).
Second-generation studies have relied on large samples, structured assessments, and mostly retrospective design to identify childhood antecedents of narcissism primarily among nonclinical samples, while focusing on single developmental factors. The third generation of studies has examined multiple factors concurrently. Those studies have documented differential etiologies for vulnerable versus grandiose narcissism and a multifactorial etiology of NPD.
Table 1 documents second- and third-generation studies (
54–
70).
Prospective studies (
71,
72) have identified temperamental characteristics, such as interpersonal antagonism, impulsivity, attention seeking, high activity level, histrionic tendencies, and low playfulness as childhood antecedents of grandiose narcissism. Vulnerable narcissism has been prospectively predicted by childhood impulsivity and unstable self-esteem (
72). Parental monitoring was found to protect against development of narcissistic traits in a prospective study (
59).
Parent-infant observational studies have highlighted putative, although untested, interactional patterns, such as lack of synchrony in emotional interactions (
73) and propensity for noncontingent marked mirroring of emotional experiences of the child (
74). We hope future studies will examine these possible antecedents in NPD etiology.
Mr. D came to treatment due to a paralysis in his career. He accepted a tenured position but found himself stuck in a perpetual cycle of procrastination and self-criticism that reduced his productivity to a dangerous low. He was ambitious and dreamt of effortlessly making groundbreaking research contributions. In treatment, he reported that his parents used to praise him unconditionally: “Everything I was doing was excellent; even when I was failing at school! I learned that no matter what I did, I was great. The word ‘success’ became meaningless to me, and I did not care to work or study hard.” Mr. D realized a close connection between his upbringing, his fantasies of effortless success, and work paralysis and started putting in effort at work.
Consistent with empirical findings of multiple developmental trajectories of maladaptive perfectionism (
75), clinical experience has shown multiple developmental trajectories of pathological narcissism, including NPD as an adaptation to neglectful parenting (emotional neglect, lack of warmth, rejection, childhood maltreatment) through overreliance on self; as an effort to protect unrealistic self-esteem (overvaluation by parents, lenient discipline, overprotective parenting) against disappointment; and as a compensation for humiliating and abusive interactions (emotional, physical, or sexual abuse and/or parental criticism).
Thus, many roads may lead to the development of NPD, and patients with similar clinical presentations may have differing developmental antecedents. This aspect highlights the importance of an open-minded exploration of a patient’s history, because making assumptions about childhood development is likely to repeat the cycle of misunderstanding.
Longitudinal Course
With numerous factors contributing to development of pathological narcissism, including NPD, one could expect a slow process of change. Overall, studies (
Table 2) (
76–
83) have documented the persistence of narcissistic pathology, even among patients who improve symptomatically. Patients with the disorder tend to improve slowly and gradually, and rapid improvements have not been documented (
84). Studies that have used categorical diagnosis of the disorder have tended to document symptomatic improvements, whereas studies that have relied on dimensional measures of pathological narcissism have tended to demonstrate stability of the disorder. A likely explanation of the disparity between the outcomes for categorical versus dimensional diagnosis has to do with the persistence of core narcissistic issues as well as of comorbid personality disorders (
84,
85). These comorbid conditions are likely contributors to the persistence of functional impairment (i.e., unrelenting challenges in interpersonal functioning, especially in the romantic arena) (
76). Age (
80–
82) is a likely moderator of outcome, as younger samples have shown slightly more improvement (
82). Life events, such as achievements, new relationships, and disillusionments, when processed in a sympathetic environment, allow some patients to learn from these experiences and to improve symptomatically (
79). On the other hand, paranoid thinking, antisocial traits, and ego-syntonic aggression impede improvement (
86). Effects of other likely moderators, such as history of adversity, employment, or interpersonal functioning, have not been tested. Taken together, these findings are consistent with the clinical observations that changes are possible, albeit slow and gradual.
Treatment of NPD
One moderator of the longitudinal course of NPD is treatment. Can treatment lead to significant change, and what treatment strategies seem to work? To date, no form of psychotherapy or pharmacotherapy has been tested empirically in randomized controlled trials. Treatments for patients with this disorder are challenging. When samples of patients with the disorder have been followed, categorical diagnosis of narcissistic personality disorder has been associated with a 63%–64% drop-out rate from psychotherapy (
87,
88), and the presence of elevated dimensional measures of pathological narcissism predicted an increased drop-out rate (
89). Factors, such as dismissive attachment, perfectionism, shame, and devaluation, have tended to predict worse outcome (
90–
93). Patients diagnosed with NPD tend to provoke powerful feelings in their therapist (
94), and these feelings, if unprocessed, often contribute to stalemates. Another frequent challenge is “nontreatment treatments”—therapies that continue despite lack of change. Typically, such nontreatment treatments take place because of a lack of clear, realistic, and measurable goals; a pervasive pattern of devaluation of treatment, competitiveness, or envy in the relationship with the therapist; or a persistent pattern of idealization, extreme therapist-pleasing behaviors, and a pattern of mutual idealization by the patient and the therapist. Patients who remain in therapy typically show slow, gradual changes, although therapeutic gains are less likely. These factors make development and validation of effective treatments for NPD an important priority.
A few pre-post studies have documented clinically significant change, including symptom reduction and improved functioning among patients (
95–
97) (Weinberg et al., 2019, unpublished manuscript), providing hope that treatments can make a difference.
Box 2 summarizes common principles in effective therapies.
How do treatments work? Motivation for coming to treatment appears to be influenced by numerous factors, such as ultimatums from work, family, or friends; dissatisfaction with life or inability to accomplish important goals; acute life crisis; worsening of another comorbid condition; and suicidality (
3). It is important to explore these motivations and to help the patient transform situational motivation into a commitment to long-term therapy.
At the outset of treatment, it is important to discuss diagnostic impressions regarding NPD with the patient (
2,
98,
99). Some patients welcome such diagnostic disclosure, whereas others experience it as a shameful label. This reaction requires sensitivity and flexibility from the clinician, who should consider discussing the diagnosis in experience-near terms without necessarily using the diagnostic label. Diagnostic disclosure anchors the treatment, aids in defining treatment goals and treatment-interfering behaviors, and helps create a longer treatment commitment. Psychoeducation helps prioritize treatment, especially when patients have comorbid disorders.
Identifying and working toward realistic goals that the patient wants to attain safe-guards against nontreatment treatment and anchors the treatment in reality. This work helps the patient develop a sense of agency, face and challenge self-defeating patterns (e.g., getting angry or paralyzed when disappointed), and develop a more functional approach to management of self-esteem and unavoidable life challenges.
Negotiation of the treatment frame addresses expectations regarding treatment (e.g., change does not happen instantly) and respective patient-therapist roles (e.g., therapist is not available around the clock). Anticipating treatment-interfering behaviors (e.g., how to handle dishonesty, substance use) may protect against early terminations or ineffective treatments.
Treatment entails close collaboration with the patient and attention to the complex and constantly changing clinical presentation. One aspect of treatment is gaining awareness of these dynamics and understanding the factors that affect the patient (e.g., feeling humiliated when evaluated). This awareness helps patients to develop a more coherent narrative about themselves (
2). However, attention to what patients with the disorder do is usually at least as important as what they say. This attention invites patients to examine their behaviors with the hope of promoting self-awareness and integration (
99,
100).
Building a collaborative treatment alliance with patients is both a strategy to increase the effectiveness of treatment as well as a treatment goal (
2). Attention to the patient’s inner experiences and behaviors, curiosity, and a nonjudgmental stance help throughout the treatment. Attention to the therapeutic relationship invites work on the ability to negotiate conflicting perceptions, staying connected through affective storms, and staying open-minded through cycles of alliance, rupture, and repair (
2,
99–
101).
Awareness of countertransference helps the clinician gain an understanding of the patient’s interpersonal patterns, as well as internal experiences that may remain outside the patient’s awareness or verbalization capacities. However, this awareness also invites clinicians to seek consultations when countertransference reactions lead to stalemates.
Treatment is expected to help the patient develop better awareness of maladaptive patterns, increase sense of agency, make progress toward measurable goals, and develop alternatives to maladaptive ways of relating to self (e.g., self-criticism) and others (e.g., admiration seeking, retaliation).
Adding couple’s or group therapy may be indicated to address relational patterns. Family therapy educates family members about the disorder, contains treatment-interfering reactions by the family, and, in some cases, addresses family dynamics (
98,
99). Case management has proven helpful for patients interested in learning life skills.
Many patients with the disorder have comorbid conditions (mood disorder, anxiety disorder, or substance use disorder) (
3). Although NPD needs to be made a priority, other conditions need to be incorporated into the treatment as well. Oftentimes, these disorders can be addressed within the treatment for NPD. However, if the patient presents with unmanaged bipolar disorder, substance use, a severe eating disorder, or obsessive-compulsive disorder, treatment of these comorbid disorders will likely require a separate focus. Such therapy may include participation in specialized substance use or eating disorder treatments.
