In this article is shown a re-riding of the historical path of psychology and cognitive psychotherapy. Cognitive psychotherapy is a field with several components, particularly fragmented and characterized by a wide multiplicity of aspects. Discussing if integration is possible it at first requires the comprehension of the differences and, most of all, the origins of these differences. The aim of this work is to give a referential context that allows to understand on which basis is nowadays possible to think about different models’ integration. The interesting perspective might be that to apply to cognitive therapy those lines which have dominated the more general integration field. We have identified four main lines: a) common factors; b) technical eclecticism; c) integrative assimilation; d) theoretical integration.
Keywords: Cognitive psychotherapy, integration.
