If the aim of behavior therapy is to help individuals with clinical pr
oblems improve their lives, then the field has been, and will continue
to be, an outstanding success. However, the same problems that were p
resent for therapy researchers in the beginning days of the field rema
in, namely, how to improve the results of treatment, and what mechanis
ms underlie the effectiveness of treatment. Some current approaches to
these problems are outlined largely in reference to the eating disord
ers. The advent of managed care will, in my opinion, be advantageous f
or the further development of behavior therapy, which is likely to rem
ain a strong field, ultimately linking therapeutic behavior change wit
h neurochemical changes in the central nervous system.
