Beck, MD, provides an understanding of how dysfunctional thinking is common to all psychological disturbances and can influence a person's mood and behaviors and vice versa ( ). Through CBT, the therapist delves deeper into the client's thoughts, beliefs about themselves, the world and others. When these thoughts become more positive, behaviors and feelings often project a more positive change as well. In adolescents with oppositional defiant disorder, CBT has been shown to be very effective in treating this disorder. It is often used to break the emotion-thought-behavior cycle. The cycle is explained as a person feeling an emotion which then leads to a particular thought that makes them uncomfortable, which then leads to negative behavior which then creates another negative feeling and the cycle continues. CBT is then used to change this cycle by creating more realistic thinking which the child can then see in terms where they are more in control and can help them see their errors in their thinking, which then leads them to behave more appropriately. ( ) Children often do not watch or even understand these thoughts or feelings and therefore act impulsively with their behaviors. With Tanyia, CBT helped her deal with her feelings of inadequacy and abandonment, which then create the idea that she is not loved or that no one loves her.
