[New problems and results in behavior therapy].

What is presently observed is not only a rapid increase in the number of publications, but also a major change in the theoretical principles of behavior therapy. The former onesidedness of a form of behavior therapy theoretically substantiated by classical conditioning only may be regarded as having been completely overcome. For example, this is evident from new approaches to behavior diagnosis as an essential prerequisite of differentiated therapy planning. Recent concepts of the theoretical substantiation of the effectiveness of behavior therapy lead to an increasing consideration of both cognitive and motivational aspects and also take into account the complexity of the patient's social relations. This, in turn, results in the availability of a wide range of indication-specific methods of behavior therapy.
