The following are all reasons why researchers have difficulty establishing prevalence rates of
childhood onset-schizophrenia except:
a. Relatively frequent revisions of the diagnostic criteria hinder researchers' ability to make
comparisons of studies conducted at different points in time and with different diagnostic
criteria.
b. Most studies of schizophrenia have been conducted with adults; studies of children and
adolescents are still rare.
c. Few studies have been conducted in non-industrialized countries.
d. Most studies have been conducted with middle- and high-income families, who are not
representative of the population as a whole.
e. The disorder is rare, making it difficult to conduct large epidemiological studies to
establish its prevalence with accuracy.
