According to the editors of New Ideas in Therapy, cognitive behaviorist theory is increasingly hampered by intrinsic theoretical limitations. A promising alternative and the subject of this book is interbehaviorism--a theory introduced by the late J.R. Kantor that looks at clinical events in terms of multiple causes and relationships operating within a integrated field or system. Written by a distinguished group of researchers and practitioners who have expanded upon Kantor's work, this study presents a new account of therapy that demonstrates, for the first time, how his field theory can be applied in modern clinical practice.
