The following are all reasons why researchers have difficulty establishing prevalence rates of
  childhood onset-schizophrenia except:

  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.
