As the population of Arab Americans grows, so does their presence among mental health clientele, creating a need among clinicians for information about these clients. The broad lines of Arab culture are delineated: its roots, language, religion, and political history; patterns of immigration to the US; and the salient differences between Arab culture and the dominant US culture. The effects of negative stereotyping and discrimination against Arab Americans are examined, as are specific clinical issues in treating them. Recommendations for more culturally sensitive treatment are enumerated.
