Psychotherapy is a general term referring to therapeutic interaction or treatment contracted between a trained professional and a client or patient; family, couple or group. The problems addressed are psychological in nature and of no specific kind or degree, but rather depend on the specialty of the practitioner. Psychotherapists employ a range of techniques based on experiential relationship building, dialogue, communication and behavior change that are designed to improve the mental health of a client or patient. Learn more about the many various branches of psychotherapy that aim to help people with a wide range of mood and mental problems in this book.
