Abstract

BACKGROUND: Grandiose narcissism has been associated with poor ability to understand one's own mental states and the mental states of others. In particular, two manifestations of Narcissistic Personality Disorder (NPD) can be explained by poor mindreading abilities: absence of symptomatic subjective distress and lack of empathy. METHODS: We conducted two studies to investigate the relationships between mindreading capacity, symptomatic subjective distress and narcissistic personality. In the first study (N = 246), we compared mindreading capacities and symptomatic distress in three outpatient samples: narcissistic patients (NPD); patients with other Personality Disorders (PD); patients without PD. In the second study (N = 1357), we explored the relationships between symptomatic distress, mindreading and specific NPD criteria. RESULTS: In the first study, the NPD patients showed poorer mindreading than the patients without PD and comparable to patients with other PDs. Symptomatic subjective distress in the narcissistic group was less severe than in the other PDs group and comparable to the group without PDs. However, no relationship emerged between mindreading and symptomatic subjective distress. In the second study, taking the clinical sample as a whole, symptomatic distress appeared negatively linked to grandiosity traits, while mindreading scores were negatively linked to empathy. CONCLUSIONS: NPD showed specific mindreading impairments. However, mindreading capacity did not appear to be directly connected with subjective distress, but did appear to be connected with specific aspects of narcissistic pathology.

TL;DR

In two Italian outpatient studies, grandiose narcissistic personality disorder (NPD) was associated with poorer interview-based mindreading than no personality disorder but similar to other personality disorders, while subjective distress was lower than in other PDs and comparable to no PD. Mindreading impairment was not linked to low subjective distress, but in a larger sample it was linked to specific narcissistic criteria, especially lack of empathy.

Key findings

  • Study 1 (N = 246: NPD n = 32, Other PD n = 157, No PD n = 57): NPD patients showed poorer mindreading on the MAI than No PD patients and comparable mindreading to Other PD patients; NPD had the lowest Differentiation and Decentration scores.
  • Study 1: NPD patients reported lower symptomatic distress (GSI) than Other PD patients and were comparable to No PD patients; no significant correlation emerged in the NPD group between symptomatic distress and alexithymia (r = .23, p = .201), symptomatic distress and metacognition (r = .16, p = .422), or alexithymia and metacognition (r = -.20, p = .316).
  • Study 2 (N = 1357): grandiosity was negatively associated with symptoms severity and alexithymia; lack of empathy was negatively associated with global MAI (β = -.18, p < .001) and positively associated with alexithymia and GSI.
  • Study 2: sense of entitlement, lack of empathy, and envy were negatively associated with global MAI; lack of empathy was negatively associated with each MAI dimension (Monitoring, Differentiation, Integration, Decentration).

Methods

  • Study 1 compared three outpatient groups selected from a larger treatment-seeking sample (N = 1346) at an Italian clinic between 2011 and 2016: NPD without other PD diagnoses, one other PD diagnosis without NPD criteria, and no PD. Measures included SCID-I/II, SCL-90-R Global Severity Index, TAS-20, and the Metacognition Assessment Interview (MAI).
  • Study 1 used MANOVA followed by univariate ANOVAs with LSD post-hoc tests and bivariate correlations.
  • Study 2 used the whole sample (N = 1357; 545 no PD, 812 at least one PD) and conducted three linear regressions with NPD criteria entered simultaneously as predictors of TAS-20, GSI, and MAI, plus regressions on the four MAI dimensions.

Limitations

  • Stated: Study 1 selected NPD patients without comorbid diagnoses, producing a smaller and less severe group than typically seen in clinical practice; findings may not transfer to the vulnerable narcissism phenotype; Study 2 was exploratory and could not clarify causal relationships between low empathy and low mindreading; analyses used categorical DSM criteria rather than dimensional measures.
  • Evident: the paper repeatedly notes small effect sizes in Study 2, and the cross-sectional design cannot establish temporal or causal direction.

  • People affected by narcissistic personality disorder describe themselves as superior but depend on and manipulate others to gain visibility and admiration.

    “People affected by NPD describe themselves as superior but, at the same time, depend on and manipulate others to gain visibility and admiration (a reality called “narcissist supply”) (27).”

    From The dark side of empathy in narcissistic personality disorder (2023) · cites this paper as [27]

    The Introduction describes NPD as involving grandiosity and pursuit of admiration, and says grandiose narcissists typically have an inflated self-image. Study 2 lists requests for admiration and interpersonal exploitation among NPD criteria. The paper does not say that people with NPD depend on and manipulate others to gain visibility and admiration, or describe this as “narcissist supply.” (LLM, conf=0.85)

Self-check

Percentages, sums and reported differences re-computed from the paper’s own numbers.

Each contradiction between two passages listed here was confirmed by an independent check.

  • Study 2's stated source sample changes size

    Minor

    Study 2 says it used the whole sample from which the Study 1 groups were selected, but Study 1 gives that source sample as 1,346 patients and Study 2 gives it as 1,357.

  • Reported MAI correlations are mathematically incompatible

    Minor

    Table 3 reports monitoring-differentiation as −.61, while monitoring-integration is .75 and differentiation-integration is .73. Three variables cannot simultaneously have those correlations: the two strong positive correlations require monitoring-differentiation to be positive.

  • Grandiosity's effect on symptom severity has conflicting signs

    Minor

    Table 4 gives a positive unstandardized coefficient (.09) but a negative standardized coefficient (−.11) for the same regression term. The text interprets the relationship as negative, which cannot be reconciled with the positive unstandardized coefficient.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Claims read by deepseek-v4.1-flash under definition version 3 (extract-v3) on 2026-10-09.

Classified by jev-1.13-20260917 (gold-guideline-v0.2) on 2026-10-09.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
