Adding:

- First paragraph: definition of Schema as well as explanation of how it works in Beck's theory

- Paragraph on what a positive cognitive triad looks like --> felt like this section focused heavily on how negative schema contribute to depression and anxiety rather than a more general detailing of theories in CBT

- Added a paragraph about Locus of control and Julian Rotter's theory

- *need to add more about how this is used in CBT; might consider adding some background on it's use for depression and anxiety to keep with the general theme of this section

Theoretical approaches[edit]
One etiological theory of depression is Aaron T. Beck's cognitive theory of depression. His theory states that depressed people think the way they do because their thinking is biased towards negative interpretations. Beck's theory rests on the aspect of cognitive behavioral therapy known as schemata. Schemata are the mental maps used to integrate new information into memories and to organize existing information in the mind. An example of a schema would be a person hearing the word "dog" and picturing different versions of the animal that they have grouped together in their mind. According to Aaron T. Beck's cognitive theory of depression, depressed people acquire a negative schema of the world in childhood and adolescence as an effect of stressful life events, and the negative schema is activated later in life when the person encounters similar situations.

Beck also described a negative cognitive triad. The cognitive triad is made up of the depressed individual's negative evaluations of themselves, the world, and the future. Beck suggested that these negative evaluations derive from the negative schemata and cognitive biases of the person. According to this theory, depressed people have views such as "I never do a good job", "It is impossible to have a good day", and "things will never get better". A negative schema helps give rise to the cognitive bias, and the cognitive bias helps fuel the negative schema. Beck further proposed that depressed people often have the following cognitive biases: arbitrary inference, selective abstraction, overgeneralization, magnification, and minimization. These cognitive biases are quick to make negative, generalized, and personal inferences of the self, thus fueling the negative schema.

On the other hand, a positive cognitive triad relates to a person's positive evaluations of themself, the world, and the future. More specifically, a positive cognitive triad requires self-esteem when viewing oneself and hope for the future. A person with a positive cognitive triad has a positive schema used for viewing themself in addition to a positive schema for the world and for the future. Cognitive behavioral research suggests a positive cognitive triad bolsters resilience, or the ability to cope with stressful events. Increased levels of resilience is associated with greater resistance to depression.

Another major theoretical approach to cognitive behavioral therapy treatment is the concept of Locus of Control outlined in Julian Rotter's Social Learning Theory. Locus of control refers to the degree to which an individual's sense of control is either internal or external. An internal locus of control exists when an individual views an outcome of a particular action as being reliant on themselves and their personal attributes whereas an external locus of control exists when an individual views other's or some outside, intangible force such as luck or fate as being responsible for the outcome of a particular action.

A basic concept in some cognitive behavioral therapy treatments used in anxiety disorders is in vivo exposure. Cognitive behavioral therapy-exposure therapy refers to the direct confrontation of feared objects, activities, or situations by a patient. For example, a woman with PTSD who fears the location where she was assaulted may be assisted by her therapist in going to that location and directly confronting those fears. Likewise, a person with a social anxiety disorder who fears public speaking may be instructed to directly confront those fears by giving a speech. This "two-factor" model is often credited to O. Hobart Mowrer. Through exposure to the stimulus, this harmful conditioning can be "unlearned" (referred to as extinction and habituation).

Cognitive behavioral therapy for children with phobias is normally delivered over multiple sessions, but one-session treatment has been shown to be equally effective and is cheaper.

Adding:

- Need to add statistics about its level of effectiveness in bipolar disorder

- include a meta analysis of CBT used for bipolar disorder

- include section on it's shortcomings for treating bipolar disorder

Bipolar disorder[edit]
Many studies show CBT, combined with pharmacotherapy, is effective in improving depressive symptoms, mania severity and psychosocial functioning with mild to moderate effects, and that it is better than medication alone.

INSERM's 2004 review found that CBT is an effective therapy for several mental disorders, including bipolar disorder. This included schizophrenia, depression, bipolar disorder, panic disorder, post-traumatic stress, anxiety disorders, bulimia, anorexia, personality disorders and alcohol dependency.
