Cognitive-behavioral therapy is a psychological treatment commonly used in psychiatry to treat patients with psychological disorders such as anxiety or depression. A patient’s cognition refers to a person’s view and perception of external things, an object or of himself, the patient’s opinion of the environment and things, etc. Cognitive-behavioral therapy is a structured, short-course, cognitively oriented treatment approach that is justified by correcting the patient’s cognition and changing the patient’s perceptions and attitudes about themselves, others or other things, so as to change the patient’s psychological problems and provide a good, positive and positive treatment effect. It has been developed for more than 50 years, and patients are able to partially improve their emotional disorders and psychiatric-psychological problems after using this treatment method, but they still rely on medication support assistance.
