title: Global function scales.
abstract: There is a close relationship between impairment of global functioning and mental illness. However valid measurement of global functioning is difficult, and there is no perfect scale. The instruments reviewed in this paper illustrate a range of different approaches. Despite the inherent difficulties the measurement of functioning is a critical domain in mental health evaluative research.
