100,000,000 Americans
Would develop mental disorders

BOSTON, June 6 - More than 46% of Americans experience a mental disorder at some point in their lives, with onset occurring by age 14 in half of all cases.

These are among the findings of four studies conducted by Ronald Kessler, Ph.D., and colleagues at Harvard Medical School. The studies were published in the June issue of the Archives of General Psychiatry.

They found that the 12-month prevalence for any disorder was 26.2%, with a prevalence of 18.1% for anxiety disorders, 9.5% for mood disorders, 8.9% for impulse control disorders, and 3.8% for substance abuse disorders.

Of these cases, 22.3% were classified as serious, 37.3% as moderate, and 40.4% as mild. Fifty-five percent of those with a disorder met criteria for only one disorder, 22% for two diagnoses, and 23% for three or more diagnoses.
