Some theoretical positions see cognitive therapy and behavior therapy as separate while others see the two as integrated forms of treatment. An open question is how these perspectives are reflected in therapeutic practice and whether in routine care one should speak from different modes and schools of treatment or rather an integrated form of cognitive-behavior therapy. Thirteen hundred and forty-four epidemiologically representative and extensive case reports, written for treatment application in routine outpatient care, were analyzed by content-analytic methods. The results indicated that cognitive and behavioral interventions were used at the same rate and in an integrated way under the heading of behavior therapy. Some differences in treatment modes were found between different mental disorders. In depressive disorders cognitive methods were slightly more prevalent (95%) than behavioral methods (86%) while in anxiety disorders behavioral technique (95%) were used somewhat more frequently than cognitive methods (83%). It was concluded that under the perspective of epidemiology of care an integrated form of cognitive behavior therapy is what therapists actually provide.
