Contextual aspects of mental disorders: a proposal for axis III of the ICD-10 multiaxial system.

After several years of development and testing, the World Health Organization (WHO) has recently completed work on the multiaxial presentation of ICD-10 for use in adult psychiatry. Axis III of the ICD-10 multiaxial system is intended for clinicians' reporting of contextual factors which may influence the diagnosis, treatment or prognosis of mental disorders that are recorded on Axis I. It was tested in two WHO-co-ordinated international field trials and found to be user-friendly, reasonably reliable and useful in routine clinical work, in the training of mental health professionals and in research on mental disorders.
