This study conducts a comparative analysis of Histrionic Personality (HP) and Narcissistic Personality (NP) traits using the Deenz Histrionic Personality Scale (DHPS) and the Deenz Narcissistic Personality Scale (DNPS), developed by Deen (2024). Both HP and NP are characterized by a strong desire for attention and admiration, yet they manifest differently. Individuals with HP exhibit excessive emotional expressiveness and attention-seeking through dramatic or manipulative behaviors, while those with NP display an inflated self-image and seek admiration through a sense of superiority. Despite overlapping traits, such as attention-seeking, the motivations behind these behaviors differ significantly. The study involved 64 participants who completed computerized versions of the DHPS and DNPS, assessing facets such as grandiosity, fantasy, entitlement, emotional reactivity, impulsivity, and empathy. Results revealed that HP traits are more emotionally reactive and driven by a need for validation through dramatic emotional displays, whereas NP traits are rooted in a rigid belief in superiority and entitlement. These findings have important implications for clinical diagnosis and intervention strategies, enhancing our understanding of these personality types and informing tailored therapeutic approaches.
