Purpose: To explore the differing interpersonal consequences of grandiose and vulnerable narcissism, in line with Wink’s (1991) conceptualization.

Narcissism: Defined as self-love, inflated self-views, self-serving bias, and a demanding display of entitlement (Campbell, Brunell & Finkel, 2006; Twenge & Campbell, 2009).
Wink’s Dual Conceptualization of Narcissism (1991):
- Grandiose Narcissism (Overt): Characterized by exhibitionistic tendencies, a desire for admiration, and a pretense of self-image maintenance.
- Vulnerable Narcissism (Covert): Features include preoccupation with grandiose fantasies, oscillation between feelings of superiority and inferiority, and fragile self-confidence.
Clinical vs Social-Personality Perspectives:
- Grandiose narcissism corresponds to social-personality conceptualization.
- Vulnerable narcissism resembles clinical conceptualizations (Miller & Campbell, 2008).

Focus on self-construal's effect on attachment styles and love styles within romantic relationships.
To validate the Narcissistic Personality Inventory (NPI) and Narcissism Inventory (NI) as measures of the respective traits.

Correlations:
- Grandiose Narcissism positively correlates with high self-esteem and independent self-construal.
- Vulnerable Narcissism negatively correlates with self-esteem and positively correlates with interdependent self-construal.
Attachment Styles:
- High vulnerable narcissism leads to higher attachment anxiety than low vulnerable narcissism.
- High grandiose narcissism implies lower attachment avoidance than low grandiose narcissism.
Love Styles:
- Vulnerable narcissism is a more powerful predictor of love styles than grandiose narcissism.

Study 1: 124 respondents (37 men, 87 women)
- Age: Mean age 28 years (SD = 10, range 18-68 years)
Study 2: 92 respondents (31 men, 61 women)
- Age: Mean age 24 years (SD = 5)
- All participants lived with a partner; average relationship length 37 months.

Self-Construal:
- Self-Construal Scale (SCS) (Singelis, 1994)
- Example items:
  - Interdependent: "I have respect for the authority figures with whom I interact."
  - Independent: "I’d rather say ‘No’ directly than risk being misunderstood."
- Internal consistency: Interdependent (α = .79), Independent (α = .63).
Self-Esteem:
- Feelings of Inadequacy Scale (FIS): 16 items (higher scores indicate higher self-esteem).
- Internal consistency: α = .85.
Narcissistic Personality Assessment:
- Narcissistic Personality Inventory (NPI): 40 items (grandiose narcissism).
- Narcissism Inventory-Revised (NI-R): 36 items (vulnerable narcissism).
- Significant correlation found between measures of both narcissism types (NPI and NI-R).
Attachment and Love Styles:
- Experiences in Close Relationships Scale (ECR): 36-item quiz assessing attachment anxiety and avoidance.
- Marburg Attitude Inventory for Love Styles (MEIL): Measures styles as per Lee (1973).
- Love styles captured: Eros, Ludus, Pragma, Storge, Mania, Agape (each love style represented by five items).

Correlations (p < .05):
- Grandiose narcissism positively correlates with self-esteem (higher NPI = higher self-esteem).
- Vulnerable narcissism correlates negatively with self-esteem (higher NI-R = lower self-esteem).
- NPI is positively related to independent self-construal and negatively related to interdependent self-construal.
- NI-R positively correlates with interdependent self-image.
Comparative Analysis for Love Styles:
- Grandiose narcissism correlated positively with Eros, Ludus, and Pragma.
- Vulnerable narcissism showed higher correlations with Mania and Agape.

Replicated Results: Confirmed findings from Study 1, emphasizing the associative patterns between narcissism types and self-esteem, self-construal, and attachment styles.
Attachment Styles: NI-R had a strong association with attachment anxiety.
- NPI correlated negatively with attachment avoidance.
Love Styles: NI-R emerged as a key predictor for positive love styles, while NPI correlated with Ludus but showed no significant connection to Agape.

Grandiose narcissism aligns with high self-esteem, independent self-construal, and various love styles primarily, while vulnerable narcissism connects with lower self-esteem, interdependent self-construal, attachment anxiety, and a wider array of love styles (especially Mania and Agape).
The evidence underscores that vulnerable narcissism plays a critical role in romantic relationships and interpersonal dynamics.
Cultural Implications: The study suggests a cultural dimension whereby Western norms foster grandiose narcissism associated with an independent view of self, compared to non-Western norms, which may emphasize vulnerable narcissism and interdependence.

Measurement Restriction: Each narcissism type was assessed by only one inventory, potentially limiting the findings' generalizability.
Participant Characteristics: Predominantly student sample, mostly female, affecting generality to broader populations.
Self-Report Bias: All data gathered via self-reports may inflate correlations due to shared method variance.
Correlational Design: Experimental manipulations are recommended to deepen insight into the relationships between narcissism types and interpersonal consequences.

This research demonstrates the importance of recognizing the duality within narcissistic traits, revealing unique psychological and relational dynamics associated with both grandiose and vulnerable narcissism. Vulnerable narcissism is emphasized as particularly influential in romantic and interpersonal contexts.
