Cognitive Behavioral Therapy 
How  Cognitive Behavioral Therapy can be used as a treatment. Article  includes an introduction to CBT, exposure therapy, the Negative Triad as  well as the successes and criticisms of the treatment.


Cognitive Behavioral Therapy is a therapeutic approach in psychology  that is intended to help individuals learn to cope with anxiety inducing  or stressful situations by rationally addressing faulty cognition and  the ways in which it leads to inappropriate and self-defeating  behaviors. For those with some knowledge of the history of psychology,  even the name of the therapy might cause some confusion, as the  disciplines of cognitive psychology and behaviorism are often seen as  being at odds with one another. In this case, however, the theorists are  more firmly on the side of cognitive psychology – they definitely hold  cognitive processes to have some degree of agency in causing behavior.  They are not simply types of behavior in and of themselves.

The whole of cognitive behavioral therapy is quite vast, with a  number of different approaches and techniques that ultimately intend to  accomplish the same goals. As a therapeutic device, it has proven quite  successful in helping diminish phobias, overcome anxiety disorders, and  relieve the symptoms of posttraumatic stress disorder.

Exposure Therapy


One of the areas in which cognitive behavioral therapy, or CBT, has  made the most strides is in dealing with anxiety and phobia. The  underlying principle behind CBT is that one holds false beliefs and  expectations about the world that adversely color our interactions with  others, causing undue stress and anxiety. The psychologist O. Mowrer was  one of the first to attempt to undermine those false beliefs with a  form of therapy intended to improve behavior by way of cognition.

This type of therapy, known as exposure therapy, worked as follows.  Suppose that you were afraid of spiders. Even if you knew rationally  that a spider wasn't poisonous and posed no threat to you, you would  still feel anxious when a spider came near you, and have feelings close  to panic if one touched you. For the cognitive psychology, what is going  on here? You hold false beliefs about spiders on some level, such that  when you're exposed to them, your experience is affected adversely by  your irrational cognition. The anxiety and fear you feel as a result  reinforces those irrational feelings, making things worse. 

With exposure therapy, you would be gradually exposed to your  stressor (spiders), while at the same time having your typical response  (anxiety and fear) suppressed. For instance, a therapist might place a  spider near you and help you maintain a sense of calm through talking  and becoming slowly and gradually acclimated to the idea of having a  spider near you. In time, you might even be able to touch the spider.  Eventually, your fears should diminish entirely. How does this work?  It's simply that, if you're exposed to a spider without allowing your  anxiety to be triggered, the stimulus of the spider gradually becomes  disassociated from the response of anxiety, and the phobia is conquered.  

Aaron Beck’s Negative Triad


Another cognitive psychologist, Aaron Beck, was the first to  formalize the idea of the cyclical interplay between environment,  cognition, and behavior, calling it the negative triad. The negative  triad works as follows.

First, one holds a "negative schema" regarding the world. Maybe this  is the expectation that you will be treated poorly by others, or that  others are looking to harm you in some way. Maybe it's simply the  expectation that any cats you meet will bring you bad luck. Whatever the  case, these negative schema are self-destructive beliefs with the  tendency to induce stress in those who hold them.

When one interacts with the world, this negative schema provides the  framework in which the interaction will unfold. If one talks to a job  interviewer with a feeling of positivity, one might have good results.  By contrast, if one talks to a job interviewer with a negative schema in  place, feeling as if the situation is hopeless, then the meeting will  probably go bad. 

When the meeting does go bad, it reinforces our negative schema. We  feel that our expectations have been met, and are thus justified. What  we need to come to realize, according to Beck, is that our negative  schema actually *cause* the poor outcomes and our own self-destructive  behaviors. With conscious recognition, however, these cognitive biases  and negative schemas can be overcome, and one can approach the world  with feelings of confidence that will ultimately produce good results. 

Success with Posttraumatic Stress Disorder

&nbsp;Elsewhere, researchers have had a great deal of success applying CBT to  posttraumatic stress disorders. Typically, those suffering from this  disorder will feel a sense of generalized anxiety as a result of an  earlier, unresolved traumatic event. Generally, this event will have led  to the formation of negative schema that can, at least theoretically,  be undone with CBT. Mark Reinecke at Northwestern University has  conducted a number of recent studies that further verify the utility of  CBT in combating posttraumatic stress disorder.

Criticisms

While CBT is one of the most popular therapeutic approaches to come out  of clinical psychology in decades, it is not well loved by everyone.  There are detractors, for instance, who claim that the relative  simplicity and low implementation cost of CBT have led to its becoming  more popular than warranted. As evidence for this, they cite the general  lack of evidence that CBT can be therapeutically effective against  schizophrenia and other psychotic disorders.

Evaluation

Cognitive Behavioral Therapy is the attempt to overcome anxiety,  depression, and neuroses through the conscious recognition of  self-destructive beliefs, with the assumption being that changing this  cognition will ultimately change one's behavior, and thusly one's  experience with the world.

CBT has had success in treating phobias through a technique called  exposure therapy that involves gradual exposure to the object of fear,  coupled with a systematic repression of the anxiety response.

Aaron Beck formalized the cyclical interplay of environment,  cognition, and behavior with his "negative triad", a cycle in which  one's negative schema affects one's experiences, and those experiences  in turn reinforce one's negative schema.

While CBT has been shown to be effective in treating posttraumatic  stress disorder, depression, anxiety, and phobias, little evidence has  been cited that it is effective in dealing with schizophrenia and other  psychotic disorders.
