HISTRIONIC PERSONALITY DISORDER

SCF-RDOS INDICATION REGISTRY ENTRY

Classification

DEFINITION

HISTRIONIC PERSONALITY DISORDER (HPD) is a personality disorder characterized by pervasive patterns of excessive emotionality, attention-seeking behavior, approval dependence, suggestibility, and interpersonal interactions driven by a persistent need to remain the focus of attention.

Individuals frequently experience discomfort when they are not the center of attention and may engage in dramatic emotional displays, provocative behavior, exaggerated self-presentation, impressionistic communication styles, or rapidly shifting emotional expressions to secure validation, affection, approval, or social engagement.

Within the SCF-RDOS framework, Histrionic Personality Disorder is conceptualized as a self-worth regulation and interpersonal-validation disorder involving dysregulation across attachment systems, self-identity architecture, emotional-expression networks, social-reward pathways, attention-allocation mechanisms, and interpersonal dependency circuits.

ETIOPATHOGENIC CORE

Primary Pathogenic Theme

An unstable internal sense of self-worth becomes increasingly dependent upon external validation, attention, approval, and interpersonal reinforcement, resulting in persistent attention-seeking behaviors and exaggerated emotional expression.
