The Effectiveness of Cognitive Behavioral Therapy (Cognitive Behavioral Therapy)IntroductionCognitive behavioral therapy (CBT) is a form of psychotherapy. Effectiveness has been the subject of extensive research over the years (Dobson, 2001). There are over three hundred published studies on the outcomes of cognitive behavioral therapy interventions. The main reason for this is that continuous adaptation of this form of psychotherapy makes it applicable to a large number of disorders and associated problems (Rounsaville and Caroll, 2002). Despite the relatively large number of studies on the effectiveness of cognitive behavioral therapy, questions remain about the levels of effectiveness for different disorders, the effects of cognitive behavioral therapy in the long term, and the implementation different studies on cognitive-behavioral therapies. behavioral therapy to prove its effectiveness. Meta-analyses can provide answers to these and related questions. For some researchers, the importance of meta-analyses on cognitive behavioral therapy is clear, as they can provide insight into comparing the treatment of different disorders with cognitive behavioral therapy (Rounsaville & Caroll, 2002). For others, however, the importance of meta-analyses is not as clear; they claim that a meta-analysis cannot say whether one form of psychotherapy is better than another. The main reason is that at least several aspects must remain constant in empirical research. Since effectiveness relies on studies across different disorders, several types of research methods are also used. Comparisons are difficult to make, just as it is difficult to draw a reliable conclusion. (Parker, Roy and Eyers, 2003). A logical alternative is to determine the effectiveness of cognitive behavior...... middle of article ......r therapy will help anyone with this form of disorder. The same goes for other disorders. It would be preferable to determine the duration of therapy on an individual basis. But whether this is done or not is unclear from the studies discussed in this article. Conclusion Cognitive behavioral therapy is moderately to very effective in the treatment of depression, generalized anxiety disorder, panic disorder, obsessive-compulsive disorder and schizophrenia. Some effects, however, are increased by using additional therapies for treatment. Questions nevertheless remain about several aspects of the therapy and the research carried out. This research was, however, limited in several respects; therefore, only a general conclusion about the positive effectiveness of cognitive behavioral therapy related to the mentioned disorders can be drawn.
