Phobias are associated with various mental health issues. The strongest associations were with anxiety disorders, panic disorders, and social phobia. This does not mean that phobias cause these other problems (or vice versa), but simply that if a person has a phobia, he or she is likelier to experience other mental health issues, as well.
