A Study by Psychologist Henry Steadman and His Colleagues Monitored

A study by psychologist Henry Steadman and his colleagues monitored the behavior of more than 1,000 former mental patients for a year after they were discharged from psychiatric facilities.

B) Compared to the control group, the former mental patients were almost three times as likely to behave violently during the year.
C) Compared to the control group, the former mental patients were more likely to be victims of violent crime.
