The assessment, diagnosis, and classification of mental disorders are
embedded in social and cultural norms. In view of their Anglo-Saxon or
igins, the prevailing diagnostic criteria and instruments for their as
sessment have a strong Western influence. Yet they are used internatio
nally with the implied assumption of their cross-cultural applicabilit
y. The WHO Cross-Cultural Applicability Research (CAR) study was desig
ned to test this assumption as it applies to disorders relating to the
use of alcohol and drugs. This multidisciplinary research project was
conducted in nine countries having different patterns of alcohol and
drug use. The results suggest that, even though some similarities exis
t with respect to the definition of problematic use of alcohol in thes
e ethnically diverse societies, very substantial differences also exis
t. A number of core concepts underpinning diagnosis of disorders relat
ing to the use of alcohol have no equivalence in the local languages o
f the various cultures, while some others lacked cultural applicabilit
y because of their relative 'distance' from cultural and ethnic norms
of drinking. This distance often relates to the difficulties of adapti
ng descriptors of drinking norms in a 'wet' culture to one that is dec
idedly 'dry'.
