July 21, 2022

The study covered in this summary was published on ResearchSquare.com as a preprint and has not yet been peer reviewed.

Key Takeaway

  • Maladaptive schemas (entitlement, vulnerability, and emotional deprivation) and cognitive evaluation systems (self-esteem and systemizing-empathizing) are associated with grandiose and vulnerable narcissism.

Why This Matters

  • The cognitive features and phenotypic diversity of narcissism subtypes are partially unknown.

  • This study integrates both grandiose and vulnerable narcissism into a common framework with cognitive components connected to these traits.

Study Design

  • This study enrolled 478 participants (397 female and 4 did not reveal their gender).

  • The average age of participants was 35 years (SD = 14.97), with a range of 18-76 years.

  • A 25-item version of the Narcissistic Personality Inventory (NPI), a 40-item self-report measure of narcissism traits, was used to assess the level of authority, grandiose exhibitionism, and entitlement/exploitativeness characteristics of study participants.

  • The Maladaptive Covert Narcissism Scale (MCNS), an expanded version of the 23-item self-report Hypersensitive Narcissism Scale (HSNS), was used to assess the level of hypersensitivity, vulnerability, and entitlement of study participants.

  • The Rosenberg Self-Esteem Scale (RSES), a 10-item self-report scale, was used to assess the level of self-esteem of study participants.

  • The Young Schema Questionnaire (YSQ-1) is a 244-item measure of 19 different maladaptive schemas and was used to observe Emotional Deprivation, Vulnerability to Harm and Illness, and Entitlement schemas of study participants.

  • The Empathizing Quotient (EQ) is a self-report measure and was used to assess the emotional intelligence of study participants.

Key Results

  • Moderate correlation between grandiose and vulnerable narcissism and the Entitlement schema was observed.

  • A moderate/strong connection was observed between vulnerable narcissism and the Vulnerability to Harm and Illness schema and a moderate connection with the Emotional Deprivation schema.

  • No significant correlation was observed between grandiose narcissism and the Emotional Deprivation schema.

  • A moderate, negative correlation between vulnerable narcissism and emotional skills was observed.

  • A positive, weak connection between grandiose narcissism and self-esteem; and a negative, moderate connection between vulnerable narcissism and self-esteem were observed.

  • Gender and age were associated with empathic skills, and age was weakly/moderately connected with self-esteem and vulnerable narcissism.

Limitations

  • This was a cross-sectional analysis investigating a temporally specific state of personality and cognitive functioning.

  • The gender ratio was shifted toward women in this study.

  • Conclusions drawn from connections between observed components are interchangeable and cause/effect connections cannot be discerned.

Disclosures

  • The study was supported by the National Research, Development, and Innovation Office (Grant No. NRDI–138040) and by the Human Resource Development Operational Program – Comprehensive developments at the University of Pécs for the implementation of intelligent specialization (EFOP-3.6.1-16-2016-00004). First author Dorian Vida's work was supported by the Collegium Talentum Programme of Hungary.

  • None of the authors disclosed any competing interests.
