What is NOT a characteristic of anxiety-based disorders?

The option that states "consistent feelings of happiness" is not a characteristic of anxiety-based disorders because anxiety conditions are fundamentally associated with negative emotional states. Individuals experiencing anxiety disorders often encounter pervasive feelings of worry, fear, and distress rather than consistent happiness.

In contrast, panic attacks, obsessive thoughts, and physical symptoms such as heart palpitations are hallmark features of anxiety disorders. Panic attacks involve sudden periods of intense fear that can trigger physical reactions, while obsessive thoughts pertain to persistent and intrusive ideas that cause significant anxiety. Physical symptoms, including heart palpitations, may occur as part of the body's response to anxiety. Understanding these characteristics helps in identifying and addressing anxiety-based disorders effectively.
