Cognitive-Behavioral Therapy for Personality Disorders (CBT)
Cognitive Behavioral Therapy (CBT) derives from cognitive-behavioral theory. CBT is a highly effective, evidence-based therapy that has been used to successfully treat a variety of mental disorders particularly depressive disorders and anxiety disorders such as Obsessive Compulsive Disorder, and Posttraumatic Stress Disorder (Paris, 2008). However, we will limit our discussion to the application of CBT in the treatment of personality disorders.
CBT techniques emerge from a fundamental premise of cognitive-behavioral theory: our thoughts (cognitions) lead to our emotions and subsequent behavior. Of particular importance for people with personality disorders is the way in which external events in the environment (such as interpersonal interactions with others) are uniquely interpreted and assigned a meaning based upon core beliefs. Childhood experiences, coupled with an innate, biologically-determined disposition, establish our initial beliefs about the world, and evolve into fairly stable, core beliefs which shape people's perceptions and interpretations of subsequent experiences. When these preconceived beliefs are faulty, distorted, or biased, we may end up drawing incorrect, irrational conclusions about the meaning of external events (particularly interpersonal interactions) and we may subsequently behave in ways that cause us unnecessary distress and suffering. For more detailed information about these concepts please return to the section on cognitive-behavioral theory.
You may recall, people with personality disorders have characteristic patterns of thinking that get them into trouble, because their ways of thinking tend to be somewhat extreme, inflexible, and distorted. CBT is particularly helpful for people with personality disorders because of its emphasis on identifying and changing dysfunctional thinking patterns while exposing and challenging the core beliefs that underlie those thoughts. Thus, cognitive-behavioral therapy functions to identify and challenge automatic and faulty interpretations of the environment that are driven by core beliefs. Once the person discontinues these faulty interpretations of the environment, and replaces them with more accurate, rational interpretations, the environment responds in kind because there is a circular causality between people and their environment: The environment has an effect upon me, and I have an effect upon my environment. These new, positive experiences allow for the person to update their core beliefs about the world, enabling them to have more positive and affirming experiences and so on. As core beliefs become more rational and less biased, the client's appraisals of the meaning of events becomes more accurate, and their emotional and behavioral reactions become less exaggerated and problematic.
There are several steps to this corrective process. First, the therapist and participant work together to identify the problematic patterns of interpretation. This is accomplished by asking the therapy participant to keep track of problematic events and to record their thoughts in response to these events. In other words, the person would be asked to keep track of what they say to themselves during these problematic events. Next, the participant would learn to consider whether there are alternative interpretations of the same event. The ultimate goal of this process is to identify the common patterns of distorted thinking and how they play out in this person's life, and then to interrupt the automatic but distorted thoughts as they occur, while learning to entertain the possibility that there may be alternative interpretations of these same events. With practice and gradual success, the recovering person begins to feel better and behave differently, and the environment responds more favorably to the new and different behavior.
Let's return to the example of the clumsy foot stepper and the man with a Paranoid Personality Disorder. His core belief, the-world-is-a-dangerous-place, causes him to misinterpret other people's behaviors as hostile and exploitive, with the intent of causing him harm. CBT would begin by asking him to record situations in which he felt threatened and to record his immediate thoughts and feelings when these situations occur. So one day when the clumsy foot stepper accidently stepped on our hypothetical man with Paranoid Personality Disorder, he might find himself thinking: "There we go again. That person just stepped on my foot intentionally. They want to hurt me. I better stand up for myself and get back at them. I'll show them! Just who do they think they are anyway?" The therapist would ask this client to consider alternatives to the conclusion the foot-stepper was intentionally trying to harm him, such as to consider that perhaps the foot-stepper was simply clumsy.
The therapist would also ask the client to rationally examine the evidence that led to the conclusion the foot-stepper was intentionally trying to harm him. For instance, how likely is it that someone would go out of their way to intentionally step on a stranger's foot, just for the sheer fun of it? If this event is highly unlikely, what caused the client to think of this unlikely explanation? In so doing, the client comes into contact with the core belief, the-world-is-a-dangerous-place, and learns to challenge that belief. Over time, the core belief is repeatedly challenged and is subsequently replaced with a core belief that is more realistic, flexible, and adaptive. As the dysfunctional core belief evolves into a more adaptive one, the client will begin to behave in ways that are less hostile and aggressive. In so doing, other people respond in kind. This new, positive experience of being treated well by other people further solidifies the new, more moderate and accurate belief, that most people are safe.
