Abstract This chapter covers the psychotherapies, a collection of treatments for mental disorders which employ language and communication as a means of producing change. It covers assessment and selection of an appropriate method for the individual patient, a history of Freud and other pioneers of psychotherapy to provide a background context, before examining different types of therapy. Briefly explaining the theory of psychotherapy, the phases of psychosexual development, and the object relations theory, it goes into detail on behavioural therapies such as cognitive behavioural therapy, interpersonal psychotherapy, dialectical behaviour therapy, and solution therapy. Counselling methods are described to aid the reader in developing their skills.
