In Australia, where about 16% of young people are born overseas and 24% are from a non-English-speaking background, adolescent health care is a multicultural challenge. "Cultural competency" involves challenging one's own cultural assumptions and beliefs, developing empathy for people from other cultures, and applying specific communication and interaction skills in clinical encounters. For health professionals, sensitivity to the cultural, ethnic, linguistic and social diversity among young people helps to avert problems and misunderstandings, improves satisfaction for all concerned and leads to better outcomes. Engaging the family and gaining the trust of parents is critical in treating young people from cultural backgrounds in which participation in health care is a family concern rather than an individual responsibility.
