The effectiveness of cognitive behavioral therapy (cognitive behavioral therapy)
Cognitive behavioral therapy (CBT) is a form of psychotherapy. The effectiveness has been researched extensively over the years (Dobson, 2001). There are over three hundred published studies about the outcomes of cognitive behavioral therapy interventions. The main reason for this is that an ongoing adaptation of this form of psychotherapy makes it applicable to a vast amount of disorders and related problems (Rounsaville & Caroll, 2002). Despite the relatively great amount of studies on the effectiveness of cognitive behavioral therapy, questions still remain about the levels of effectiveness for different disorders, about the effects of cognitive behavioral therapy on the longer term, and about the set up of the different studies on cognitive behavioral therapyin proving its effectiveness.
Meta-analyses can give answers to these and related questions. For some researchers, the importance of meta-analyses on cognitive behavioral therapy is clear, since it can give insight in the comparison on the treatment of different disorders with cognitive behavioral therapy (Rounsaville & Caroll, 2002). For others however, the importance of meta-analyses is not so clear; they state a meta-analysis cannot tell whether one form of psychotherapy is better than another. The main reason is that at least several aspects must be kept constant in an empirical research. Since the effectiveness is studies for different disorders, also several kinds of research methods are used. Comparisons are difficult to make, just as drawing a realiable conclusio. (Parker, Roy & Eyers, 2003). A logical alternative is to determine the effectiveness of cognitive behavioral therapy for several disorders and draw a more general conclusion about the overall effectiveness. This paper therefore focuses on several known disorders and its treatment by cognitive behavioral therapy. The next section will discuss shortly the content of cognitive behavioral therapy. Then the effectiveness of cognitive behavioral therapy for several disorders will be presented as is known in literature. However, it is out of the scope of this paper to present all known literature on this subject. Therefore, literature mentioning het main results about the effectiveness of cognitive behavioral therapy will be presented. The differences and similarities will be discussed and at the end the conclusion will provide insight in the overall effectiveness.
Cognitive behavioral therapy
Cognitive behavioral therapy differs in several respects from more traditional forms of therapy. It focuses on two specific elements: cognitive restructuring and behavioral activation. The client and therapist work together in cognitive restructuring with the goal to restructure thinking patterns. In behavioral activation, the client overcomes barriers to participating in activities. The main focus is on the present and on specific...
