DEPENDENT PERSONALITY DISORDER

SCF-RDOS INDICATION REGISTRY ENTRY

Classification

DEFINITION

DEPENDENT PERSONALITY DISORDER (DPD) is a personality disorder characterized by a pervasive and excessive need to be taken care of that leads to submissive behavior, fear of separation, excessive reliance on others for guidance and reassurance, difficulty making independent decisions, and persistent concerns regarding abandonment.

Individuals with Dependent Personality Disorder frequently subordinate their own needs, preferences, beliefs, and goals to maintain attachment relationships and avoid perceived rejection or abandonment. The disorder is associated with impaired autonomy, diminished self-efficacy, excessive reassurance seeking, and chronic dependency on external support systems.

Within the SCF-RDOS framework, Dependent Personality Disorder is conceptualized as a maladaptive attachment-regulation disorder involving dysfunction across attachment systems, self-identity architecture, autonomy-development pathways, emotional-regulation mechanisms, interpersonal-security networks, and decision-making systems.

ETIOPATHOGENIC CORE

Primary Pathogenic Theme

Failure of autonomous self-development and secure attachment formation resulting in chronic dependency on external individuals for emotional security, decision-making, identity validation, and functional regulation.
