Quality of life: a dimension in multiaxial classification

The study provides an overview of the historical aspects of multiaxial classification. Particular reference is paid to the multiaxial formats of ICD-10, DSM-IV and the WPA International Guidelines for Diagnostic Assessment (IGDA). The IGDA proposes a tetraaxial format with quality of life as one axis as well as an axis on symptomatology, an axis on adaptive functioning and an axis on environmental/psychosocial conditions. The axis on quality of life is added in recognition of the increasing importance placed upon the patient's perception of his/her capacity of self fulfillment and the attention paid to quality of life as a major descriptor of health status as well as an outcome measure of clinical care.
