People Who Were Treated in State Hospitals During the Mid-1900s

People who were treated in state hospitals during the mid-1900s often developed additional symptoms that were more troubling than the original symptoms for which they were being treated. This is thought to be due to:

A) the dehumanizing conditions associated with being institutionalized.
B) the spread of contagious diseases that occur when people are overcrowded.
C) poorly trained nurses who failed to respond to the needs of patients.
D) the side effects of dangerous treatment procedures that were routinely used.
