We now see interventions as what happens when a family and a therapist are together; that is, we see the whole interview as a punctuation in the family's experience which can make a difference to them. Our evidence for saying this is the kind of deductions we make from hunches about non-verbal behaviour during interview, and the fact that family members begin to be able to give information from another level, which suggests they are no longer stuck with the bit of the belief system which caused them to give the kind of information they presented at the beginning. This has been called 'interventive interviewing' (see Tomm 1987). In the case of the Johnson family discussed earlier (Page 22), the following dialogue from the last session with them illustrates this point.
