DEFINITION
GENERALIZED ANXIETY DISORDER (GAD) is a chronic anxiety condition characterized by excessive, persistent, and difficult-to-control worry regarding multiple domains of life, including health, finances, relationships, work, family, safety, future events, and routine daily responsibilities.
The anxiety is disproportionate to actual risk, persists for extended periods, and is accompanied by physical, cognitive, emotional, and behavioral symptoms that impair daily functioning. Individuals often experience a near-constant state of apprehension, anticipation of negative outcomes, heightened vigilance, and inability to achieve sustained psychological relaxation.
Within the SCF-RDOS framework, Generalized Anxiety Disorder is conceptualized as a chronic threat-anticipation disorder involving dysregulation across threat-detection systems, uncertainty-processing networks, emotional-regulation pathways, autonomic stress systems, cognitive-control mechanisms, and adaptive resilience architecture.
ETIOPATHOGENIC CORE
Primary Pathogenic Theme
Persistent overactivation of threat-detection and future-risk anticipation systems generates chronic worry, heightened vigilance, physiological stress activation, and maladaptive anxiety-maintenance cycles.

Uncertainty Intolerance | Persistent worry generation |
Emotional-Regulation Dysfunction | Anxiety persistence |
Cognitive Biases | Catastrophic expectation formation |
Stress-System Dysregulation | Physiological anxiety activation |
Hypervigilance | Constant threat monitoring |
Maladaptive Coping Behaviors | Anxiety reinforcement |
