In the original plan of our book we set aside a chapter in order to review all the major models from a user-friendly point of view. However, this task has proved over-ambitious, so we have decided to limit ourselves to the two major influences within family therapy during the 1980s. As we have demonstrated in the opening chapters of our book, user-friendliness was primarily developed in order to address weaknesses in the way some of the original models of family therapy had been formulated. Family therapy has not remained static during the last 10 years, so it is necessary to ask the important question: have other models of family therapy evolved that can make a significant contribution to user-friendliness? Our preliminary answer to this question is that it is probably the ‘second-order’ models and models based on feminism that can contribute most to userfriendliness, but we also acknowledge that many other models (sadly unreviewed by us) are also capable of contributing important ideas.
