The disruption of psychosocial functioning (PSF) is currently listed as one of the DSM-IV diagnostic criteria for schizophrenia and PSF is increasingly recognized as an important determinant of a successful treatment of the disease. However, despite the widespread use of the term, there is limited consensus about its definition and measurement. The workshop will provide a review of current definitions and measures of PSF in schizophrenia and an update of findings on PSF relationships with symptoms, cognitions and ICF. The inclusion of PSF in ICD-11 diagnostic criteria for schizophrenia will also be discussed.
