What is the defining characteristic of generalized anxiety disorder?

Generalized anxiety disorder (GAD) is characterized primarily by persistent and excessive worry about various aspects of everyday life, often accompanied by a state of chronic tension and apprehension. Individuals with GAD find it difficult to control their worry and this anxiety can manifest in physical symptoms such as restlessness, fatigue, difficulty concentration, and muscle tension.

The defining aspect of this disorder is indeed the continual experience of tension and apprehension about a range of issues, such as health, work, social interactions, and daily responsibilities. This sense of unrest can affect the individual’s overall quality of life and daily functioning, leading to significant distress.

In contrast, other options describe features of different mental health conditions. For instance, a state of constant happiness and well-being does not align with anxiety disorders but rather suggests emotional stability or contentment. An obsession with specific thoughts is more characteristic of obsessive-compulsive disorder. Meanwhile, an overwhelming desire to avoid social interaction relates more closely to social anxiety disorder or avoidant personality disorder. Thus, the correct answer accurately captures the essence of generalized anxiety disorder.
