Psychotherapy (also psychological therapy or talking therapy) is the use of psychological methods, particularly when based on regular personal interaction with adults, to help a person change behavior and overcome problems in desired ways. Psychotherapy aims to improve an individual's well-being and mental health, to resolve or mitigate troublesome behaviors, beliefs, compulsions, thoughts, or emotions, and to improve relationships and social skills. There are also numerous types of psychotherapy designed for children and adolescents, such as play therapy. Certain psychotherapies are considered evidence-based for treating some diagnosed mental disorders. Others have been criticized as pseudoscience.
