Man is committed by his biological and cultural evolution to a social existence. While the social environment is the source of many stressors, it may also be protective. This latter function is called 'support'. Social bonds are to be found universally, but some cultural groups have the integrity of these bonds conspicuously endangered. The application of the affective component of the social network to psychiatry promises to be useful, but cannot progress further until an instrument is developed for assessing the support available to an individual. We have gone some way towards a method for assessing the components of primary group interaction. The task now is to determine if low social support, such as is seen in Western suburban wives, some migrant groups and some women in the Middle East and Asia, is causally related to some psychiatric disorders The principal appeal of this area is that we may be tapping something very fundamental about human social organisation, something which, unlike adversity, is subject to modification
