The authors studied the hospital records of 400 hospitalized mentally
ill patients for evidence of violent behavior leading to admission. They
found that 36% of 321 admissions (excluding patients diagnosed as having a
personality disorder or as drug-and/or alcohol-dependent) were preceded by
some form of violent, fear-inspiring behavior. They suggest that mental
health professionals deal with the general public's fear of the mentally
ill on the basis of such findings rather than dismiss it as illogical.
