Cultural Considerations
 Culture shapes the expression of some psychiatric
symptoms.
Ex. The content of hallucinations
 Some disorders are culture-bound.
Ex. Bulimia
 Psychiatric disorder exists only in societies that medicalize
distress.
 Psychiatric disorders can also be viewed as expressions of
social problems.
