Which symptom is most likely to be reported by individuals with anxiety disorders?

Individuals with anxiety disorders commonly experience sleep disturbances, making this the most likely symptom to be reported. Anxiety often leads to difficulties in both falling asleep and staying asleep, resulting in symptoms such as insomnia, restless sleep, or nightmares. This relationship is due to the hyperarousal and incessant worry characteristic of anxiety, which can interfere with the body's ability to relax and achieve restful sleep.

In contrast, increased appetite is typically associated with depression rather than anxiety. Consistent happiness is also not a symptom of anxiety disorders; individuals with anxiety often experience feelings of dread or worry. Reduced social interaction can occur as a result of anxiety, as individuals may avoid situations that provoke anxiety, but it is more of a consequence of the disorder rather than a primary symptom that individuals are likely to report. Hence, sleep disturbances stand out as a core symptom that those experiencing anxiety are likely to identify.
