Cultural assessment in a healthcare setting

“Health defined by one cultural group may be different than that for another cultural group. For example, a child with a seizure disorder may be described as healthy and protected by higher powers in the H’mong culture, whereas the same child may be described as ill and disabled in a Western culture.” (Fadiman, 1997)
