Depression and anxiety differentially influence physical symptom reporting. A study found that people who felt more depressed believed they had experienced more symptoms, even accounting for physical signs of depression. Another study found that participants induced to feel anxious reported a higher number of current physical symptoms. A third study found that anxious participants reported more current symptoms while depressed participants reported more retrospective symptoms. The researchers concluded that depression is associated with exaggerated recall of negative past experiences while anxiety is associated with vigilance of potential threats in the present.
