Objective: Recent studies have suggested a link between a primary anxiety disorder and ADHD. Method: A total of 39 participants with a primary diagnosis of social phobia were compared with 178 patients with ADHD and 88 patients with other psychiatric disorders on measures for childhood and adult ADHD (the Wender Utah Rating Scale and the Adult ADHD Self-Report Scale). Results: Childhood symptoms of ADHD were reported by 7.8% of the social phobia participants, and 5.1% scored within the range of adult ADHD. The social phobia group reported significantly fewer ADHD symptoms than both of the comparison groups, who frequently reported social anxiety. Conclusion: Participants with social phobia recruited from the general population are less likely to suffer from ADHD. In contrast, patients with ADHD and patients with other psychiatric disorders appear to be likely to suffer from social anxiety. (Contains 1 note and 2 tables.)
