DEFINITION

INTERNET ADDICTION is a behavioral addiction characterized by excessive, compulsive, and poorly controlled internet use that persists despite negative consequences and leads to significant impairment in personal, social, educational, occupational, psychological, or physical functioning.

The condition extends beyond frequent internet use. Individuals experience loss of control over online behavior, preoccupation with internet-related activities, withdrawal-like symptoms when unable to access digital platforms, escalating use over time, neglect of responsibilities, and continued engagement despite awareness of harm.

Within the SCF-RDOS framework, Internet Addiction is conceptualized as a digital reinforcement and reward-capture disorder involving dysfunction across reward-processing systems, executive-control networks, attentional-allocation mechanisms, behavioral-reinforcement pathways, emotional-regulation architecture, and social-adaptation systems.

ETIOPATHOGENIC CORE

Primary Pathogenic Theme

Continuous access to highly reinforcing digital stimuli progressively captures attention, activates reward pathways, weakens inhibitory control mechanisms, and establishes compulsive internet-use patterns that impair adaptive functioning.

Core Pathogenic Drivers

Domain	Contribution
Digital Reward Reinforcement	Compulsive engagement
Dopaminergic Stimulation	Behavioral repetition
Executive-Control Dysfunction	Reduced self-regulation
Emotional-Avoidance Coping	Dependency formation
Social-Reinforcement Mechanisms	Usage escalation
Variable Reward Schedules	Habit consolidation
Attention Fragmentation	Cognitive impairment
Behavioral Conditioning	Addiction persistence
