with influences coming from many sources. Some of these contributory streams have been information pro­ cessing, behavior therapy, Constructivist psychology, and dynamic psychotherapy. Each of these sources have added color, shading, and depth to the CT model. What was originally uni­ dimensional in terms of the CT focus on depression has become multidimensional as the CT model has been applied to virtually every patient population, treatment setting, and therapy context. CT must now be seen as a general model of psychotherapy that, with modifications, can be applied to the broad range of clinical problems and syndromes. What has tied these various applications of CT together is the emphasis on a strong grounding in cogni­ tive theory, a commitment to empirical support, and a dedication to broadening the model.
