CBT includes a variety of approaches and therapeutic systems; some of the most well known include cognitive therapy, rational emotive behavior therapy and multimodal therapy. Defining the scope of what constitutes a cognitive–behavioral therapy is a difficulty that has persisted throughout its development.
The particular therapeutic techniques vary within the different approaches of CBT according to the particular kind of problem issues, but commonly may include keeping a diary of significant events and associated feelings, thoughts and behaviors; questioning and testing cognitions, assumptions, evaluations and beliefs that might be unhelpful and unrealistic; gradually facing activities which may have been avoided; and trying out new ways of behaving and reacting. Relaxation, mindfulness and distraction techniques are also commonly included. Cognitive behavioral therapy is often also used in conjunction with mood stabilizing medications to treat conditions like bipolar disorder. Its application in treating schizophrenia along with medication and family therapy is recognized by the NICE guidelines within the British NHS.
Going through cognitive behavioral therapy generally is not an overnight process for clients; a typical course consists of 12-16 hour-long sessions. Even after clients have learned to recognize when and where their mental processes go awry, it can in some cases take considerable time or effort to replace a dysfunctional cognitive-affective-behavioral process or habit with a more reasonable and adaptive one. Cognitive Behavioral Therapy is problem focused and structured towards the client, it requires honesty and openness between the client and therapist, as a therapist develops strategies for managing problems and guiding the client to a better life.
