Final answer:
People with an anxiety disorder are more likely to experience another anxiety disorder compared to other types of psychiatric disorders. Anxiety disorders can co-occur, with individuals sometimes having more than one disorder within the anxiety spectrum.
Step-by-step explanation:
People with an anxiety disorder are most likely to experience a second anxiety disorder. This is supported by the fact that mental illnesses can often occur in clusters, with individuals suffering from one disorder being at increased risk for developing another, particularly within the same category such as anxiety disorders. Conditions like post-traumatic stress disorder (PTSD), obsessive-compulsive disorder (OCD), panic disorder, and phobias all fall within the anxiety spectrum, and it's not uncommon for someone to struggle with more than one of these issues. This is different from mood disorders, such as major depression or bipolar disorder, which are also common but not as likely to co-occur with anxiety disorders to the same extent.
