One Trend in Psychiatry Over the Years, as Seen in the Development

One trend in psychiatry over the years, as seen in the development of DSM-IV, has been to

A) collapse all psychiatric diagnoses into just a few major categories, instead of drawing distinctions among different types of disorders.
B) give a psychiatric diagnosis to more and more clients, including some who have only minor and understandable difficulties.
C) treat more and more people with psychoanalysis and fewer people with drugs or other medical interventions.
D) keep people in large mental hospitals for longer and longer periods of time.
