DEFINITION
Online Social Isolation Syndrome (OSIS) is a psychosocial condition characterized by progressive reduction in meaningful real-world interpersonal engagement despite ongoing or excessive digital social activity, resulting in loneliness, diminished belonging, impaired social fulfillment, and deterioration of relational wellbeing.
Individuals with OSIS may appear socially connected due to:
- Frequent social media activity
- Online gaming participation
- Digital communication
- Virtual communities
- Continuous internet engagement
However, underlying social needs remain insufficiently fulfilled through meaningful reciprocal relationships, producing a mismatch between perceived connectivity and actual social nourishment.
Within the SCF framework, OSIS is conceptualized as a social-attachment dysregulation disorder involving disruption of belongingness systems, social-reward pathways, identity integration networks, interpersonal reciprocity mechanisms, and community-engagement architecture.
ETIOPATHOGENIC CORE
Primary Pathogenic Theme
Digital interaction progressively substitutes for meaningful interpersonal connection, resulting in reduced social nourishment, weakened attachment fulfillment, diminished belonging, and chronic social deprivation.
Core Pathogenic Drivers
Domain | Contribution |
Excessive Virtual Interaction | Social displacement |
Reduced Face-to-Face Contact | Attachment deficits |
Superficial Social Engagement | Relational insufficiency |
Algorithmic Social Reinforcement | Behavioral dependence |
Social Comparison Exposure | Emotional distress |
Loneliness Amplification | Isolation persistence |
Community Disengagement | Belonging reduction |
Identity Fragmentation | Relational instability |
