Ratings of behaviour and family relationships were made on the basis of (a) a non-schedule standardised interview, (b) direct observation of family interaction during a meal time and (c) direct observation of mother-child interaction during free play. A number of scales met a battery of reliability and other criteria, and possible generalisation of these ratings across methods (interview versus direct observation) and settings (meal time versus free play) was assessed. For the vast majority of scales this was low. Reasons for this, together with some clinical implications, are discussed.
