Empathy Deficits and Familial Impact of Narcissistic Personality Disorder Subtypes: A Quantitative Analysis of Relational Dynamics

Abstract Background: This study explores Narcissistic Personality Disorder (NPD) by analyzing how grandiose and covert narcissistic traits impact family dynamics. Leveraging psychoanalytic theory and quantitative methodologies, it investigates empathy deficits as a core mechanism behind manipulative behaviors and relational dysfunction associated with NPD. The study employs the Narcissistic Personality Inventory (NPI) and the Interpersonal Reactivity Index (IRI) to quantitatively assess empathy and its relational effects across narcissistic subtypes. Case Representation A case analysis of a 65-year-old man with grandiose narcissism highlights significant family discord resulting from his manipulative interactions. Structural equation modeling (SEM) reveals that his empathy deficits are key in perpetuating relational dissatisfaction, underscoring the subtype-specific pathways through which narcissistic traits impact family cohesion. Conclusion: The findings emphasize empathy deficits as a central mediator in the relationship between narcissistic traits and family dysfunction. This study advocates for subtype-specific therapeutic approaches—targeting behavioral regulation for grandiose narcissists and empathy development for covert narcissists—to improve relational outcomes. Future research should adopt longitudinal approaches to further investigate these dynamics across diverse cultural contexts. Keywords – cognitive empathy, covert narcissism, grandiose,
