cognitive behavior therapy (CBT), a common form of psychotherapy used to help people become aware of and to change their inaccurate or negative patterns of thinking. Unlike many traditional psychotherapies, cognitive behavior therapy (CBT) is not directed at uncovering the origins of a person’s particular problem. Instead, CBT focuses on how people’s thinking patterns affect their emotions and behaviors. By changing these patterns, individuals can become better able to manage their emotions and alter their behaviors, and they can learn to deal more realistically and effectively with the problems and stresses in their lives. For many people, CBT is more effective than other types of psychotherapy because it requires fewer sessions to achieve positive results.
CBT can be used alone or with other therapies and psychiatric medications to treat a wide range of mental health conditions. These include post-traumatic stress disorder, phobias (irrational fears), attention deficit/hyperactivity disorder (ADHD), anxiety disorders, excessive anger, obsessive-compulsive disorder, substance abuse, and eating disorders. In addition, CBT methods have helped those without mental health issues to learn to manage periods of high stress, such as those resulting from the death of a family member.
Historical development
Modern CBT has its roots in the 1950s and ’60s, when psychologists and psychiatrists working in South Africa, England, and the United States began to study the use of psychotherapeutic interventions based on principles of learning theory. Before long, behavior therapy became an established form of treatment that included exposure-based strategies, techniques based on classical and operant conditioning, and other strategies aimed at directly changing problem behaviors.
By the early 1960s the term behavior therapy had appeared in several important publications. Related terms, such as behavior modification, began to be used more frequently during the decade. In 1963 the first scientific journal devoted to behavior therapy (Behaviour Research and Therapy) began publication, and in 1966 the Association for Advancement of Behavior Therapy (AABT) was formed.
In the 1960s and ’70s several psychologists began to combine behavior therapy with cognitive treatments meant to change clients’ negative patterns of thinking and information processing. Although a number of individuals played important roles in the early advancement of cognitive treatments, Aaron Beck and Albert Ellis are most often credited with the development of these treatments. Both were originally trained as psychoanalysts, and both described their dissatisfaction with traditional psychoanalysis as the reason they sought to develop new approaches to treating depression, anxiety, and related problems. Ellis referred to his form of treatment as rational emotive therapy and, later, rational emotive behavior therapy, and Beck used the term cognitive therapy. Both treatments were focused on helping clients to shift their beliefs, assumptions, and predictions from being negative, depressive, anxious, and dysfunctional to being more realistic, positive, and adaptive. With effective behavioral and cognitive treatments becoming more established, researchers in the 1970s and ’80s began to develop protocols that included strategies from both forms of treatment.
Forms of treatment
Duration, frequency, and format of CBT sessions vary greatly, depending on the type of problem being treated, the therapist’s availability, and the client’s preferences. Typically, treatment consists of 10–20 sessions, usually occurring weekly. However, individuals with complex presentations (e.g., significant comorbidity and personality disorders) may take longer than 20 sessions to treat, and individuals with very-focused problems (e.g., specific phobias) can often be treated in a much smaller number of sessions. Treatment may occur individually or in groups.
Although CBT is often administered on an outpatient basis, there are also inpatient and day-treatment programs based on a CBT approach. CBT sessions usually begin with the therapist and client collaborating to set an agenda for the meeting. The bulk of each session is spent teaching, reviewing, or applying specific CBT strategies to the client’s problems. Early sessions are often more didactic, with the therapist describing how to use particular techniques, while in later sessions more time is spent using the new strategies. Homework is often assigned to encourage clients to review and practice the CBT strategies on a daily basis.
Dialectical behavior therapy (DBT) is a type of CBT that emphasizes the acceptance of all feelings and behaviors while at the same time attempting to change some of those behaviors.
Client assessment
A variety of assessment procedures are used to understand the client’s therapeutic needs, to determine which CBT techniques to use in treatment, and to measure progress. As with almost all forms of psychotherapy, the clinical interview is an important tool for therapists who use CBT. In addition to the usual topics covered during the interview (e.g., history of the presenting problem, personal and family history, etc.), CBT therapists inquire about the types of behavioral excesses and deficits that are associated with the client’s difficulties, the triggers and consequences of problem behaviors, and the types of cognitions that are associated with negative mood states such as anxiety, depression, and anger. Often, semi-structured interviews are used to ensure a standardized approach to assessment that is unlikely to accidentally miss important features of the problem.
Direct behavioral observation involves observing a client in a relevant situation and noting behaviors and responses of interest. For example, when treating social anxiety disorder using CBT, therapists may first administer a behavioral approach test (BAT), in which the client confronts a feared situation (e.g., a casual conversation with a stranger, or a brief presentation). During the BAT, the therapist has the opportunity to observe the client in order to note any skill deficits and to observe any avoidance or safety behaviours that are used during the test. After the BAT, clients typically report on the severity of their anxiety and on any anxious thoughts that occurred during the exercise. Behavioral observation has the advantage, over other forms of assessment, of being able to identify behaviors or other features of a problem of which a client may be unaware.
Monitoring diaries are forms that clients complete on a regular basis to measure relevant symptoms or to monitor their use of particular CBT strategies. For example, in the treatment of depression it is common to have clients monitor their depressive thoughts and to use cognitive diaries to challenge their patterns of negative thinking. An advantage of monitoring diaries is that they avoid problems of retrospective recall bias. By having clients report on their symptoms as they occur, they are more likely to provide an accurate account of the frequency and severity of their symptoms than they might be if they were simply trying to re-create the memory of the symptoms while sitting in the therapist’s office several days or weeks later.
Numerous standardized scales exist for measuring the most important features of almost every diagnostic category. For anxiety disorders alone, more than 200 empirically supported scales were in use in the early 21st century. For example, in the case of panic disorder and agoraphobia, scales measure the frequency of panic attack symptoms, the severity of agoraphobic avoidance, and the extent to which the client is fearful of panic-related sensations (a hallmark feature of panic disorder). Information obtained on self-report scales can be used to help select targets or goals for treatment as well as to select the most appropriate strategies for dealing with the problem.
