Diagnostic and Statistical Manual of Mental Disorders (4th ed.) BDD was assessed with a reliable semi-structured measure. For participants with BDD, severity of BDD symptoms was assessed with the Longitudinal Interval Follow-up Evaluation Psychiatric Status Rating scale. At the initial assessment, 17 participants (3.3%; 95% confidence interval = 1.8%–4.8%) had current BDD; 22 (4.3%; 95% confidence interval = 2.6%–6.1%) had lifetime BDD. Participants with BDD had significantly lower Global Assessment Scale scores than those without BDD, indicating poorer functioning. The probability of full recovery from BDD was 0.76, and probability of recurrence, once remitted, was 0.14 over the 8 years. In conclusion, among individuals ascertained for anxiety disorders, the probability of recovering from BDD was relatively high and probability of BDD recurrence was low. *Rhode Island Hospital, Providence, RI; and Departments of †Psychiatry and ‡Family Medicine, Warren Alpert Medical School of Brown University, Providence, RI.
