ABSTRACT
This chapter examines the ways of revising underlying assumptions and rules. Assumptions are best tested with behavioural experiments. The 'If' part of the assumption put to the test in order to determine if the 'then' part realized. Fennell suggests that 'alternatives to dysfunctional assumptions can written on flash-cards for patience to read repeatedly until acting accordance with them becomes second nature'. Behavioural experiments can used straight away to test the usefulness of clients' new rules and assumptions instead of being used first to test validity of the old ones. Mooney and Padesky suggest a several advantages if the focus on constructing new rules and assumptions: Changes occur more quickly. The collaborative process is creative rather than revisionist. Client motivation and interest increased. More change may occur if a panorama of possibilities considered instead of the constricted vision offered by focusing on old patterns of behaviour.
