How should we measure social disadvantage in clinic settings?

Background: Despite a large research literature supporting their validity, deprivation indices derived from census data have not been routinely applied to clinic populations.

Method: A case-note sample of 201 cases was examined, to identify whether such data (Jarman indices) predicted presenting disability separately from diagnostic class (behaviour, emotional, mixed, other, and no diagnosable disorder), or conventional clinic measures of social adversity (ICD-10 psychosocial diagnostic codes).

Results: Jarman index scores predicted disability in behaviour disorders or other disorders. Conventional clinic measures of adversity predicted disability in mixed disorders. For emotional disorders, and those cases with no diagnosed disorder, clinically measured adversity and Jarman scores interacted.

Conclusions: Postcode related census data capture information about clinic children's presenting disability that is not available from routine clinic assessment of psychosocial adversity. It should therefore be collected as part of the routine clinical child psychiatry assessment.
